Deinstitutionalization in Ontario: A History for Families of Adults with Developmental Disabilities

Updated 2026-07-08advocacy-self-determination

If you’re supporting an adult with a developmental disability in Ontario, it helps to know where today’s services came from — because the values we now take for granted (community, inclusion, choice) were forged in reaction to more than a century of harm. For 133 years Ontario ran large residential institutions for people with developmental disabilities, and the movement to close them is the direct ancestor of the group homes, day programs, and direct-funding supports families rely on now. This page is a sober, sourced history: what the institutions were, how life inside was documented, why Ontario’s record differs from other provinces, how the reckoning unfolded in the courts and the Legislature, and why families and advocates still warn that the old model could quietly return.

This is a neutral, sourced reference, current as of 2025–2026. Historical terms such as “asylum for idiots,” “feeble-minded,” “retarded,” and “developmentally handicapped” appear only where they are needed for accuracy. They are offensive and are not endorsed here. Survivor experience is presented soberly and with respect.

The short version

  • For 133 years (1876–2009) Ontario ran a network of large residential institutions for people labelled “idiots,” “feeble-minded,” and later “developmentally handicapped.” The system began with the Orillia Asylum for Idiots (1876, later the Huronia Regional Centre) and grew to roughly sixteen provincial facilities by the mid-1970s, housing tens of thousands of children and adults in overcrowded, understaffed, and frequently abusive conditions.
  • Life inside was documented as neglectful and violent from at least Pierre Berton’s 1960 Toronto Star exposé onward: overcrowding, restraint and seclusion, forced unpaid labour, medication misuse, and physical, emotional and sexual abuse — corroborated by survivor testimony, the 1971 Williston Report, and the class-action litigation record.
  • Ontario’s institutional era was shaped by eugenics but, crucially, Ontario never passed a sterilization statute — unlike Alberta (1928–1972; 2,832 sterilizations performed) and British Columbia (1933–1973; an estimated few hundred). The 1917–1920 Hodgins Royal Commission recommended segregation but deliberately sidestepped sterilization.
  • Ontario’s last three large institutions — Huronia (Orillia), Rideau (Smiths Falls), and Southwestern (Blenheim/Cedar Springs) — all closed by March 31, 2009 (Southwestern in 2008). Survivor class actions produced settlements: $35 million for Huronia (2013), $32.7 million combined for Rideau and Southwestern (2013–14), and $35.9 million for twelve more “Schedule 1” institutions (2015–16). Premier Kathleen Wynne apologized in the Legislature on December 9, 2013.
  • The Community Living movement (parent associations from the late 1940s–1950s; the Ontario body founded 1953, the national body 1958) drove closure and remains the replacement model, built on inclusion, citizenship and person-centredness. But the promise was underfunded: tens of thousands remain on waitlists, and advocates warn of “re-institutionalization” in hospitals and long-term care.

What every family should know

1. The scale was enormous and long-lived. Institutionalization in Ontario spanned 1876–2009. By the mid-1970s the province operated about sixteen facilities. One advocacy tally holds that more than 50,000 people passed through these institutions across the era. Huronia alone had a peak of roughly 2,600 residents; at least 4,000 people died there in its first century.

2. The abuse was systemic, not incidental. Warnings existed from at least 1960 (Berton) and were formalized in the 1971 Williston Report, yet conditions persisted for decades. The litigation described overcrowding, understaffing, failure to implement abuse-prevention policies, and deliberate exploitation of residents’ unpaid labour.

3. Ontario’s eugenic record is distinct. Ontario embraced institutional segregation and had prominent eugenicists (Helen MacMurchy, C.K. Clarke, Clarence Hincks), but it never enacted sterilization legislation — a key contrast with Alberta and BC.

4. The reckoning was legal and public. Survivor-led class actions and the December 9, 2013 Premier’s apology constitute the formal acknowledgment. But survivors have criticized the settlements as inadequate, the claims process as retraumatizing, and the treatment of the Huronia cemetery as disrespectful.

5. The values that replaced the institution grew directly out of rejecting it. Normalization (Nirje, Wolfensberger), social role valorization, and the Community Living movement produced today’s emphasis on inclusion, Self-Advocacy for Adults with Developmental Disabilities in Ontario: A Plain-Language Guide, and person-centredness — and a deep distrust of congregate/segregated settings, now sharpened by concern about “re-institutionalization.”

Where it began: Orillia, 1876

Ontario’s first institution specifically for people with developmental disabilities opened in Orillia in 1876. A branch of Toronto’s Provincial Lunatic Asylum had operated in a converted Orillia hotel from around 1859–1861 but closed by about 1870; in 1876 the province reopened the site as an independent facility, the Orillia Asylum for Idiots (also rendered “Asylum for Idiots and Imbeciles”). The first residents — about forty-four — arrived by train on September 25, 1876. In 1885 the province acquired land on Lake Simcoe two miles outside Orillia for a purpose-built “cottage plan” institution; the first cottages opened in 1887–1888 and the administration building in 1891.

The facility changed names repeatedly, tracking shifting ideology and euphemism:

  • Orillia Asylum for Idiots (1876)
  • Hospital for Idiots (1890)
  • Hospital for the Feeble-Minded (1911)
  • Ontario Hospital School (1936, reflecting a nominal educational role; came under the Department of Health in 1930)
  • Huronia Regional Centre (1974, on transfer to the Ministry of Community and Social Services)

Sources vary slightly on some dates: Thelma Wheatley and others date the “Ontario Hospital School” renaming to the 1930s, and the “Huronia Regional Centre” name to 1974, though some accounts say 1973. The 1876 opening, the eventual “Huronia” name, and the 2009 closure are firmly established.

The population climbed for decades. By 1908 there were about 775 residents; Berton reported 2,807 patients in late 1959; peak figures are cited between roughly 2,000 (1968) and about 2,600. Thereafter the population fell: about 1,857 daily average in April 1971; 1,812 in 1975; 583 in 1996; fewer than 350–360 by 2004, when the average resident age was about 49. In 1960 there was reportedly a waiting list of about 4,000 children, with three admitted per day and departures (by discharge or death) at less than half that rate.

The system expands: Rideau, Southwestern, and the wider network

As demand overwhelmed Orillia, the province built more. The two other very large facilities were:

  • Rideau Regional Centre, Smiths Falls — opened 1951 as an Ontario Hospital School; became Ontario’s largest such institution, peaking above 2,500 residents (one source cites exceeding 2,600 in 1955, though it was built for about 1,500). Closed 2009. The site later became the mixed-use Gallipeau Centre.
  • Southwestern Regional Centre, Cedar Springs/Blenheim (Chatham-Kent) — opened 1961 as the “Ontario Hospital School for Retarded Children at Cedar Springs”; the last large institution built in Ontario. Population reached about 1,200 (1966), with figures near 937 (1971) depending on the count, reduced to about 620 by 1979. Closed 2008. Demolished 2020.

By the mid-1970s Ontario operated roughly sixteen facilities. Others named in the later “Schedule 1” litigation include: Pine Ridge (Aurora), St. Lawrence Regional Centre (Brockville), D’Arcy Place (Cobourg), Adult Occupational Centre (Edgar), Bluewater Centre (Goderich), Muskoka Centre (Gravenhurst), the Children’s Psychiatric Research Institute/CPRI (London), Midwestern Regional Centre (Palmerston), Prince Edward Heights (Picton), Adult Rehabilitation and Training Centre (St. Thomas), Northwestern Regional Centre (Thunder Bay), Surrey Place Centre (Toronto), Durham Centre for the Developmentally Handicapped (Whitby), Oxford Regional Centre (Woodstock), Nipissing Regional Centre (North Bay), and L.S. Penrose Centre (Kingston).

Life inside

Documentation of conditions is extensive and consistent. Disease and infection were leading causes of death; the frequency of deaths from easily treatable enteritis is read by historians as evidence of poor care. Residents from a young age performed unpaid labour — food growing and preparation, laundry, garbage collection, cleaning shared washrooms, childcare, landscaping, shovelling coal — often “working full days by the age of 10.” Neglect, restraint, seclusion, medication errors, and physical, verbal, emotional and sexual abuse were reported. Residents lived in filthy, overcrowded, pest-infested conditions; children were sometimes confined to “cage cribs.”

The most famous early warning was journalist Pierre Berton’s column in the Toronto Daily Star, published early January 1960 (variously dated Jan. 6 or Jan. 7; titled “What’s Wrong at Orillia: Out of Sight, Out of Mind”). Having toured the Ontario Hospital School on New Year’s Eve 1959 — with the help of parent-advocate Jerry Anglin — Berton described 2,807 people in a facility built for under 1,000: beds “crammed together, head to head,” an “appalling” stench, and fire-unsafe buildings. He wrote: “Remember this: After Hitler fell, and the horrors of the slave camps were exposed, many Germans excused themselves because they said they did not know what went on behind those walls: no one had told them. Well, you have been told about Orillia.” The Minister of Health, Dr. M.B. Dymond, conceded the next day that the overcrowding charges were “perfectly true.” The government responded partly with a reassuring film, “One on Every Street.”

Survivor testimony gathered by the Recounting Huronia collective (a 2013–2016 arts-based project led by scholars including Kate Rossiter and Jen Rinaldi with survivor co-researchers, now a community archive at Wilfrid Laurier University) and the Remember Every Name survivors’ group documents violence “as care,” lifelong trauma, and loss. Author Thelma Wheatley and historians Kate Rossiter and Annalise Clarkson (“Opening Ontario’s ‘Saddest Chapter’: A Social History of Huronia Regional Centre”) provide historical accounts; Madeline Burghardt (Broken: Institutions, Families, and the Construction of Intellectual Disability) analyzes family impact. Filmmaker Barri Cohen’s 2022 documentary Unloved: Huronia’s Forgotten Children traced her two half-brothers institutionalized at Huronia in the 1950s; one, Alfie, died there in 1973.

The eugenics context — and what did and did not happen in Ontario

The institutional project was justified in part by eugenics — the belief that “feeble-mindedness” was hereditary and that segregating (and preventing the reproduction of) “defectives” would improve society. Ontario had influential eugenic advocates, notably Dr. Helen MacMurchy (Inspector of the Feeble-Minded, ~1906–1919), Dr. C.K. Clarke, and Dr. Clarence Hincks (co-founders of the Canadian National Committee for Mental Hygiene, 1918).

Involuntary sterilization did become law in two provinces:

  • Alberta’s Sexual Sterilization Act (1928–1972): created a four-member Eugenics Board; amended in 1937 to remove the consent requirement. Per Grekul et al., “Sterilizing the Feeble-Minded: Eugenics in Alberta, Canada, 1929–1972” (Journal of Historical Sociology, 2004), of 4,785 cases presented (99% approved), 2,832 sterilization operations were completed. Women and marginalized groups (Indigenous, Métis, immigrants, the poor) were disproportionately targeted. Leilani Muir sued Alberta and won: Justice Joanne B. Veit ruled for her on January 25, 1996 (Muir v. Alberta, 1996 CanLII 7287 (AB QB)), awarding C$740,780 in damages plus C$230,000 in legal costs, finding “the circumstances of Ms. Muir’s sterilization were so high-handed … that the community’s, and the court’s, sense of decency is offended.” Her case opened the door to hundreds more claims: by 1999 Alberta had paid roughly $142 million to more than 700 victims (about 500 claimants settling for $48 million in 1998, followed by an $82 million package for 247 more in 1999).
  • British Columbia’s Sexual Sterilization Act (1933–1973): created a Board of Eugenics; narrower in scope. Estimates of those sterilized vary — historian Angus McLaren estimated “no more than a few hundred,” and other estimates cluster around 200–400 (one figure: ~330). About nine in ten sterilized were women.

Ontario is the crucial contrast: it never passed a sterilization statute. The province appointed the Royal Commission on the Care and Control of the Mentally Defective and Feeble-Minded in 1917, headed by Justice Frank Egerton Hodgins (final report ~1919–1920). It recommended segregation of the “feeble-minded,” marriage restrictions, and psychiatric and court reforms — but pointedly avoided explicitly eugenic language and declined to recommend sterilization (analyzed in C. Elizabeth Koester’s “An Evil Hitherto Unchecked,” Canadian Bulletin of Medical History, 2016, and her book In the Public Good: Eugenics and Law in Ontario). Despite lobbying (including from the Eugenics Society of Canada, formed around 1930), no Ontario sterilization law was ever enacted. This does not mean no sterilizations of institutionalized Ontarians ever occurred, but there was no legal sterilization regime comparable to Alberta’s or BC’s. This distinction matters for accuracy and is frequently blurred in popular accounts.

The turn against institutions

Multiple forces converged from the 1940s onward:

  • Parent movements / Community Living. Excluded from schools (children with IQ under 50 were barred by law), parents organized. A teacher in Kirkland Lake, Donald Frisby, opened a class for six children in April 1947; local associations formed across Ontario. The provincial body — founded April 27, 1953 as the Ontario Association for Retarded Children (later the Ontario Association for the Mentally Retarded; the Ontario Association for Community Living in 1987; now Community Living Ontario) — held its first meeting in Toronto in 1953. The national body, the Canadian Association for Retarded Children, was founded in 1958 (later the Canadian Association for the Mentally Retarded, 1969; Canadian Association for Community Living, 1985; Inclusion Canada since September 14, 2020).
  • Normalization and social role valorization. The normalization principle emerged in Scandinavia in the 1960s (Bank-Mikkelsen in Denmark; Bengt Nirje of the Swedish association, whose 1969 formulation called for “patterns and conditions of everyday life which are as close as possible to the norms of the mainstream of society”). Wolf Wolfensberger brought it to North America and, in 1983, reframed it as social role valorization. Nirje later worked in Toronto with the Ministry of Community and Social Services, giving Ontario a direct link to these ideas.
  • Media exposés (Berton 1960; National Film Board footage; ongoing later coverage).
  • Government reports. The 1971 Williston Report (Toronto lawyer Walter B. Williston, commissioned after the deaths of two Rideau residents, Frederick Elijah Sanderson and Jean Marie Martel) found conditions very poor and urged gradual institutional closure and reinvestment in community and family services. Robert Welch’s 1973 report advanced community-based service policy; the Developmental Services Act (1974) formalized the shift and moved responsibility from Health to Community and Social Services.
  • Cost pressures. Institutions were widely seen as financially inefficient; deinstitutionalization aligned with federal cost-sharing (the Canada Assistance Plan, 1965) and the appeal of cheaper, privatized community housing.

Deinstitutionalization and closure (1970s–2009)

Populations fell steadily from the 1970s as residents moved to group homes, foster care and other community settings — the beginnings of the Housing and Residential Options for Adults with Developmental Disabilities in Ontario families navigate today. Ontario’s institutions closed one by one over the following decades. On September 9, 2004, the government announced the “Facilities Initiative” to close the last three large institutions. Southwestern (Blenheim) closed in 2008; Rideau and Huronia closed on March 31, 2009 — the date the last resident left Huronia, ending Ontario’s 133-year institutional history. About 941 residents were repatriated to the community in the final phase; the government reported investing $276 million to support the moves. Some families opposed closure (the “Huronia Helpers”; a Divisional Court challenge). Government-commissioned evaluations reported that families and agencies perceived the vast majority of those who moved as having “excellent or good” quality of life — though these were perception surveys, not independent outcome audits.

The class actions and the reckoning

  • Huronia (Dolmage v. Ontario): Lead plaintiffs Patricia Seth and Marie Slark (each institutionalized around age six or seven), with litigation guardians Marilyn and Jim Dolmage (Marilyn a former Huronia social worker whose brother Robert died at the institution). Filed 2009, certified 2010, represented by Koskie Minsky LLP (Kirk Baert, Celeste Poltak, David Rosenfeld). The suit sought $1 billion; it settled September 17, 2013 for $35 million just as trial began. It was approved by the Ontario Superior Court on December 3, 2013. Terms included individual payments (up to roughly $35,000–$42,000 depending on severity), release of about 65,000 documents to the Archives of Ontario, cemetery maintenance and a burial registry, and the Premier’s apology. Roughly 3,700 surviving residents were eligible. Survivors later criticized the rollout: about half the fund reached survivors, roughly $8.5 million went to legal fees, about $3 million to the class proceedings fund, and non-verbal claimants were reportedly downgraded to a $2,000 minimum.
  • Rideau (McKillop) and Southwestern (Bechard): Settlements announced December 2013, approved February 24–25, 2014 by Justice Barbara Conway, totalling $32.7 million$20,619,000 for Rideau and $12,081,000 for Southwestern (the difference reflecting population size). Lead plaintiff for Rideau: David McKillop. About 4,300 former residents were covered; terms included a Premier’s apology and a plaque.
  • The twelve additional “Schedule 1” institutions: Certified August 20, 2015; a $35.9 million settlement was reached in November 2015 and approved April 25, 2016. It covered facilities including Pine Ridge, D’Arcy Place, the Adult Occupational Centre (Edgar), Bluewater, Muskoka Centre, Midwestern, Prince Edward Heights, Northwestern, Oxford, Durham and others. Attorney General Madeleine Meilleur called the compensation fair. Notably, this settlement came without a separate apology or project fund, and unclaimed funds reverted to the government — a departure criticized by advocates. (A related certified action, Yeo v. Ontario, settled in 2021 for CPRI in London, reported around $12 million.)

The apology. On December 9, 2013, Premier Kathleen Wynne rose in the Legislative Assembly and apologized to former residents of Huronia, Rideau and Southwestern — a landmark moment in the recognition of the Rights, Accessibility, and Anti-Discrimination Law for Adults with Developmental Disabilities in Ontario of Ontarians with developmental disabilities. Verified excerpts (Hansard / official text): “I offer an apology to the men, women and children of Ontario who were failed by a model of institutional care for people with developmental disabilities… As Premier and on behalf of all the people of Ontario, I am sorry for your pain, for your losses and for the impact these experiences must have had on your faith in this province and in your government. I am sorry for what you and your loved ones experienced and for the pain that you carry to this day… In the case of Huronia, some residents suffered neglect and abuse within the very system that was meant to provide them care. We broke faith with them and with you, and by doing so, we diminished ourselves.” She noted residents “were forcibly restrained, left in unbearable seclusion, exploited for their labour and crowded into unsanitary dormitories.” Opposition leaders Tim Hudak (PC) and Andrea Horwath (NDP) also apologized — significant to survivors because abuse occurred under Liberal, PC and NDP governments alike.

The Huronia cemetery and unmarked graves

Huronia was the only Ontario institution in the asylum system with its own cemetery. Before 1958, graves were marked only with sequential numbers (assigned by order of death), purportedly to protect privacy; from 1958 markers bore names and dates. The last burial was in 1971. The counts are contested: commonly cited figures are 571 marked graves and about 1,440 unmarked; the province’s confirmed list (compiled in 2014 with Remember Every Name) names 1,379 people, while the 1990 government monument and archaeological uncertainty suggest possibly “more than 2,000.” At least 4,000 people died at Huronia in its first century, though many were buried elsewhere by families. Grave markers were removed and reused as paving/walkway stones in the 1970s–80s; a 2014–15 investigation (Timmins Martelle Heritage Consultants, using ground-penetrating radar) prompted allegations that a septic/sewage system had been installed through burial rows — a handling that survivors and forensic anthropologist Dr. Jerry Melbye disputed. Survivors, using leftover settlement funds (“Investing in Justice”), commissioned a Survivors’ Memorial Monument (sculptor Hilary Clark Cole), unveiled August 24, 2019.

The Community Living movement as the replacement model

The parent associations that fought to open schools and close institutions became the backbone of community-based services. Community Living Ontario is today a confederation of more than 100 local affiliates and a provincial member of Inclusion Canada. The governing philosophy — inclusion, citizenship, self-determination, person-centredness, inclusive education, and Self-Advocacy for Adults with Developmental Disabilities in Ontario: A Plain-Language Guide — is a direct repudiation of the institution. Ontario’s legislative framework followed suit: the Developmental Services Act (1974) gave way to the Services and Supports to Promote the Social Inclusion of Persons with Developmental Disabilities Act (2008), marking a rhetorical shift from “community living” to “social inclusion.”

Why this history still matters — and the honest complications

Deinstitutionalization’s promise was real, but its funding was not fully delivered. Community services were chronically under-resourced, producing what critics call transinstitutionalization — the recreation of institutional dynamics in group homes and the drift of people into other congregate settings. Key present-day concerns (2024–2026):

  • Waitlists. Community Living Ontario states that “Over 50,000 adults with developmental disabilities are currently on the waitlist for services in Ontario,” with fewer than 35,000 receiving support, and “only about a third of the 3,000 people who apply for services each year actually receive them” (Waiting2Belong campaign, Dec. 2024–Jan. 2025; drawing on Financial Accountability Office (2024) and Auditor General figures). The FAO reported that the supportive-living (residential) waitlist grew about 55% since 2018 even as the number housed fell, and more than 30,000 people wait for full Passport funding.
  • Re-institutionalization. Adults with developmental disabilities are documented being warehoused in hospitals (alternate level of care) and long-term care homes for lack of appropriate community Housing and Residential Options for Adults with Developmental Disabilities in Ontario — sometimes for years, and sometimes at young ages. A peer-reviewed ICES/CAMH study (Selick, Lunsky et al., Canadian Journal of Psychiatry, September 2025) found that of 1,466 long-stay psychiatric inpatients in Ontario on September 30, 2023, 22% (about 322 people) had an intellectual/developmental disability — a group that is under 1% of the population; an earlier CAMH snapshot put the comparable figure higher (555, or 28%), a discrepancy attributable to differing case definitions. The Ontario Ombudsman’s report “Nowhere to Turn” (Paul Dubé, August 24, 2016) investigated 1,436 complaints, detailed 18 cases and made 60 recommendations (all accepted by the ministry), calling the pattern “a modern-day version of institutionalization” in which “institutional care no longer happens through design but by default.”
  • Reform status. Ontario’s “Journey to Belonging: Choice and Inclusion” — the ministry’s plan (released 2021, framework updated April 2022) to move to individualized/needs-based direct funding — remained in the design/consultation stage as of 2024–2026 and had not been implemented; Community Living Ontario supports the direction but calls it “not enough” without a more expansive, evidence-based and transition-funded strategy.
  • Aging survivors. Institutional survivors are aging; their testimony, preserved by Remember Every Name and Recounting Huronia, is a finite resource, lending urgency to remembrance work.

The historical continuity is the point: the values that define good practice today — community, inclusion, person-centredness, and a wariness of segregated congregate care — were forged in reaction to a documented century of harm. The modern worry is that fiscal pressure and inadequate community capacity could quietly reproduce the very model Ontario apologized for.

Grey areas and points of confusion

  • Death tolls and burial counts at Huronia. “At least 4,000 died in the first century” is widely cited; buried-on-site counts range from a confirmed 1,379 names to estimates of “more than 2,000,” with about 1,440 graves unmarked. Poor record-keeping, removed markers, and disputed radar findings make a precise figure impossible.
  • Peak populations. Sources differ: Huronia’s peak is cited between ~2,000 (1968) and ~2,600; Rideau above 2,500 (one figure of 2,600+ in 1955); Southwestern ~1,200 (1966) or ~937 (1971).
  • Name-change dates. The “Ontario Hospital School” (1930s, often given as 1936) and “Huronia Regional Centre” (1973 vs. 1974) renamings are dated slightly differently across sources.
  • Numbers sterilized. Alberta: 2,832 operations completed (Grekul et al., 2004; also rendered “over 2,800” or “nearly 3,000”). BC estimates vary widely (a “few hundred,” 200–400, ~330).
  • Settlement accounting. Headline totals ($35M Huronia; $32.7M Rideau+Southwestern; $35.9M for twelve more) are firm, but how much actually reached survivors versus legal fees, the class proceedings fund, and reverted unclaimed money is disputed and criticized.
  • Modern warehousing figures. Estimates of people with developmental disabilities stuck long-term in psychiatric beds vary by definition and dataset (e.g., 322/22% peer-reviewed vs. 555/28% snapshot for the same date); cite with source and date.
  • Interpretive dispute. Government-commissioned evaluations frame the 2009 transition positively; survivor and disability-studies scholarship frames deinstitutionalization as incomplete and, in some settings, reproduced. Both perspectives are represented here.

How current is this, and what to double-check

  • Recency: Facility histories and settlement facts (2008–2016) are stable and well-documented. Present-day waitlist, hospital-warehousing, and reform-status figures are current to 2024–2026 and will change; verify the latest data before relying on it.
  • Source reliability: The strongest sources are the litigation record (Koskie Minsky filings, court approvals), Hansard (the 2013 apology), peer-reviewed histories (Rossiter & Clarkson; Brown & Radford; Koester on the Hodgins Commission; Grekul et al. on Alberta), survivor/remembrance projects (Remember Every Name, Recounting Huronia), and independent government offices (Ombudsman, Auditor General, Financial Accountability Office, ICES). Some population and death-toll figures originate in secondary or advocacy sources and are flagged as such. Where sources conflict, both figures are given rather than one chosen silently.
  • Language: Historical names and clinical terms of the era are offensive and are used only where necessary for historical accuracy.
  • Survivor experience is presented soberly and with respect; this page intentionally avoids sensational detail while not minimizing documented harm.

Frequently asked questions

When did Ontario’s institutions for people with developmental disabilities close?

Ontario’s last three large institutions closed by March 31, 2009 — Southwestern (Blenheim) in 2008, and Rideau (Smiths Falls) and Huronia (Orillia) on March 31, 2009. That date ended a 133-year institutional era that began with the Orillia Asylum for Idiots in 1876.

Did Ontario ever sterilize people with developmental disabilities by law?

No. Unlike Alberta (Sexual Sterilization Act, 1928–1972; 2,832 operations performed) and British Columbia (1933–1973; an estimated few hundred), Ontario never passed a sterilization statute. The 1917–1920 Hodgins Royal Commission recommended segregation but deliberately declined to recommend sterilization.

Was there ever an apology or compensation for institution survivors?

Yes. Survivor class actions produced settlements of $35 million for Huronia (2013), $32.7 million combined for Rideau and Southwestern (2013–14), and $35.9 million for twelve more “Schedule 1” institutions (2015–16). Premier Kathleen Wynne apologized in the Legislature on December 9, 2013, though survivors criticized the settlements as inadequate.

What replaced Ontario’s institutions?

The Community Living movement — parent associations that organized from the late 1940s, with the Ontario body founded in 1953 — drove closure and became the model of community-based services built on inclusion, citizenship, and Self-Advocacy for Adults with Developmental Disabilities in Ontario: A Plain-Language Guide. Residents moved into group homes and other community settings from the 1970s onward.

Is institutionalization really over in Ontario?

Not entirely, advocates warn. Community services were chronically underfunded, and adults with developmental disabilities are still documented being housed long-term in hospitals and long-term care for lack of community Housing and Residential Options for Adults with Developmental Disabilities in Ontario — a peer-reviewed 2025 study found about 322 people (22% of long-stay psychiatric inpatients) had an intellectual/developmental disability. Over 50,000 adults remain on service waitlists.

How many people were institutionalized, and how many died at Huronia?

By the mid-1970s Ontario ran about sixteen facilities, and one advocacy tally holds more than 50,000 people passed through them. At least 4,000 people died at Huronia in its first century; burial counts remain contested, ranging from a confirmed 1,379 names to estimates of “more than 2,000.”
