Future & Succession Planning in Ontario: A Guide for Aging Parents of an Adult with a Developmental Disability

If you’re an aging parent supporting an adult with a developmental disability in Ontario, the question “what happens when I’m gone?” can feel too large and too painful to face. This guide is meant to make it manageable. It walks through what a future plan actually contains, why a planned transition protects your son or daughter far better than an emergency one, and the free Ontario help that exists — with every figure sourced and dated. The reassuring truth underneath it all: the antidote to dread is a concrete, staged plan you build while you’re still well.

The short version

• The question is universal and urgent, but the fix is a process, not a single document. For the first time in history, adults with a developmental disability routinely outlive their parents, so nearly every aging caregiver faces the “what happens when I’m gone?” question — and the antidote to dread is a concrete, staged plan built while the parent is still well.
• A future or “lifetime” plan has six parts: (1) a person-centred vision of a good life; (2) a residential plan; (3) a financial plan; (4) a legal and decision-making plan; (5) a support network beyond the parents; and (6) a written record of the person’s routines, preferences and needs (often called a “letter of intent” or personal profile).
• Emergency and planned transitions produce very different outcomes. In Ontario, when a sole caregiver dies or is hospitalized without a plan in place, the person often lands in a crisis placement decided by strangers; a gradual, planned transition consistently protects wellbeing and skills better.
• The support network is the load-bearing wall. Models such as PLAN-style personal support networks, circles of support, and Microboards exist specifically so the person is not left alone when parents are gone — relationships, not just money, are the core safeguard.
• Help exists, and much of it is free. Ontario families can draw on Partners for Planning, PLAN, Family Alliance Ontario networks, Community Living organizations, DSO housing navigators, independent facilitators, and a portion of Passport funding for person-directed planning.

What every family should know

1. You are not an outlier; this is a demographic wave. The H-CARDD program’s population-based cohort identified 66,484 adults with developmental disabilities in Ontario (2009–2010 data), and peer-reviewed researchers restate “more than 66,000” as recently as 2025. Ontario’s April 2023 MCCSS (Ministry of Children, Community and Social Services) Minister’s briefing counted roughly 11,200 people with a developmental disability living with a caregiver aged 60 or older, projected to reach about 17,400 within five years (cited in the Ombudsman’s November 2025 report).

2. Waitlists mean you cannot assume a residential spot will appear when you need it. More than 52,000–53,000 Ontarians with developmental disabilities are on waitlists for developmental services, including over 28,000 waiting for supportive housing (2025). Wait times are severe: End The Wait Ontario (updated March 2026) reports that DSO group homes and supported independent living carry “20+ year waitlists in some regions,” and OASIS reports the housing waitlist “grows by about 1,200 every year” (up from roughly 13,000 waiting in 2014). See Housing and Residential Options for Adults with Developmental Disabilities in Ontario.

3. Avoidance is common and costly. Few families make formal plans or involve siblings; the cost of avoidance is emergency placement, hospitalization “by default,” and the loss of hard-won skills.

4. Planning is protective — and it starts now. The single most important move is to register with Developmental Services Ontario (DSO) as early as eligibility allows and to begin building a plan and a network while the parent is healthy, not in crisis.

5. Money is necessary but not sufficient. Trusts and RDSPs secure finances, but a person’s safety over a lifetime is most strongly tied to the number and quality of their relationships.

Why this affects nearly every aging caregiver

How many adults, and how many aging caregivers? The most rigorous Ontario population figure comes from the H-CARDD program at CAMH, whose Atlas identified a cohort of 66,484 adults with developmental disabilities using linked administrative data (2009–2010), a prevalence of about 0.78% — higher than the 0.5% previously assumed. The Ontario Ministry had earlier estimated about 62,000 adults (2012) using the older prevalence assumption; both figures circulate, but the H-CARDD administrative-data figure is more robust. Recent peer-reviewed work (2025) continues to cite “more than 66,000.”

The aging-caregiver figure is the heart of this guide. Ontario’s April 2023 MCCSS Minister’s briefing — cited in the Ombudsman’s November 2025 Lost in Transition report — stated that 11,200 people with a developmental disability live with a caregiver aged 60 or older, expected to rise to approximately 17,400 within five years. Nationally, the 2018 General Social Survey (analyzed by Palmeter, O’Donnell & Smith and published by the Public Health Agency of Canada in Health Promotion and Chronic Disease Prevention in Canada, May 2025) found that 79.2% of care receivers with a developmental disability lived in the same household as their caregiver.

People are living much longer. Per the National Down Syndrome Society and Global Down Syndrome Foundation, “As recently as 1983, a person with Down syndrome lived to be only 25 years old, on average. Today, the average life expectancy of a person with Down syndrome is almost 60 years and continuing to rise.” For intellectual disability generally, life expectancy (outside severe or multiple disability) now approaches that of the general population. This is the demographic engine behind the “my child will outlive me” reality — and behind Family Alliance Ontario’s framing that “for the first time in history children with a disability will outlive their parents.”

Aging brings earlier frailty. H-CARDD found that as early as age 50, adults with developmental disabilities show frailty levels comparable to adults without disabilities aged 80+. Home-care use is highest at ages 45–54 (versus 75+ for the general population). This means the person and the caregiver are often both aging and declining at the same time.

The result is a wave of unplanned emergency transitions. Because system capacity is “maxed out,” a Ministry official told the Ombudsman that “basically somebody has to pass away in order to create a vacancy.” When a caregiver dies or is hospitalized suddenly, the person frequently enters an emergency placement — or, for those with complex needs, is inappropriately hospitalized.

Why planning gets avoided — and what avoidance costs

Future planning is emotionally heavy: it forces parents to imagine their own death and their child’s life without them. Research on siblings (Burke, Taylor, Urbano & Hodapp, 2012) found that few families make formal plans or involve siblings in planning at all. Yet the cost of avoidance is severe and well-documented in Ontario:

• Crisis placements decided by strangers. Without a plan, decisions about where a person lives and who supports them fall to whichever agency or ministry has a vacancy or a legal duty — not to people who know the person.
• Hospitalization “by default.” The Ombudsman’s November 2025 Lost in Transition report — the product of an investigation launched in March 2023 that examined 55 complaints and involved more than 120 interviews — documented seven adults who “languished in hospitals for years” awaiting appropriate housing; one young man was “tied to his bed and chemically sedated for most of his two years in hospital,” another was restrained at times “for up to 20 hours a day.” As of December 2024, Ontario Health reported 124 adults with developmental disabilities living in hospitals who no longer required acute medical care.
• Loss of skills. The Ombudsman found that during long hospitalizations “individuals often lose hard-won life skills,” and the longer the stay, the harder it becomes to find an agency willing to help them transition.

A planned transition, by contrast, lets the person visit, adjust gradually, and move while a parent is still alive to smooth the process and correct problems.

The six parts of a future or “lifetime” plan

A complete plan has six interlocking parts. This guide owns the process; several parts are covered in depth by AIM’s separate guides.

1. The vision, or person-centred plan. A clear articulation of what a good life looks like for this specific person — where and how they want to live, work, contribute, and connect. In Ontario, person-directed planning is formally recognized: families can use a portion of Passport funding to pay for it, and DSO publishes a guide to person-directed planning.
2. The residential plan. Where the person will live and with what supports (kept high-level here — see the network and housing sections below, and Housing and Residential Options for Adults with Developmental Disabilities in Ontario).
3. The financial plan. How the person will be financially secure — including ODSP, the RDSP, Henson trusts, and life insurance. The mechanics of trusts, RDSPs and ODSP asset rules are covered in AIM’s separate guide on Henson Trusts and Estate Planning for a Family Member on ODSP in Ontario. The RDSP (introduced in 2007) is widely regarded as the single most important disability-specific savings tool in Canada.
4. The legal and decision-making plan. How decisions will be made — powers of attorney, guardianship, or supported decision-making arrangements. Capacity and decision-making mechanics are covered in AIM’s separate guide on Legal Decision-Making in Ontario: Capacity, Powers of Attorney and Guardianship — A Family Guide.
5. The support network. The circle of committed people who will stay in the person’s life (see the next section).
6. The record of routines, preferences and needs — the “letter of intent” or personal profile (see the emergency-file section below).

The support network: building relationships beyond parents

This is the part families most often overlook, and the one that most determines lifelong safety. The Planned Lifetime Advocacy Network (PLAN), founded in Vancouver in 1989 by parents, is built on the premise that “safety is directly related to the increased number and quality of relationships in one’s life.” PLAN and its affiliates help families identify trusted friends, neighbours and community members, then nurture reciprocal relationships and prepare network members to take on advocacy and decision-making roles as parents age.

Several models put this into practice in Ontario:

• Personal support networks / circles of support: an intentional group of friends and family who commit to staying in the person’s life. Partners for Planning (formerly PLAN Toronto), founded in 2009 “by families and for families,” provides free resources and independent facilitation to build them, explicitly to answer “Who will love and protect our sons and daughters when we no longer can?”
• Independent facilitation: a facilitator “walks with” a person and family to build a community-based plan centred on the person’s gifts, and to develop and nurture the network. Families can find facilitators through the Ontario Independent Facilitation Network (OIFN) or Partners for Planning’s Professional Services Directory.
• Microboards: a small group (minimum five people) of family and friends who incorporate a non-profit around one person, formalizing the network so it can hold assets, administer individualized or direct funding, and provide lifelong governance. Microboards Ontario (incorporated provincially in 2018) supports their creation, drawing on the model that Vela Canada has used to create more than 1,000 such corporations in B.C. since 1990.

Residential transition: plan before crisis

Housing models are covered in AIM’s separate housing guide, but the succession-planning point is essential: a gradual, planned residential transition beats an emergency one. DSO is the single access point and maintains the service registry; families are advised to register as early as eligibility allows (application can begin at 16; eligibility at 18) precisely because waits are long and needs-based. DSO also offers housing navigators who help families build individualized housing and support plans beyond the traditional group-home model. Because vacancies are scarce, the practical strategy is to register early, keep the DSO file updated as circumstances change (the family’s ability to keep providing care is a factor in the priority score), and begin transition steps — overnight stays, respite, skill-building — years before they are needed.

The “what if I’m hospitalized tomorrow?” file

Distinct from the long-term plan, every family needs a grab-and-go emergency file that a substitute caregiver could use tonight. The widely used tool is a “letter of intent” (also called a letter of instruction or personal profile) — a document that is not legally binding but serves as an “instruction manual” for whoever steps in. It should be reviewed at least annually and stored with the family’s legal documents, and its existence and location must be known to the future caregiver. At a minimum it should capture:

• Identity and contacts: the person’s full legal name, date of birth, health card and key ID; and names and contact details for family, friends, doctors, therapists, and support workers.
• Medical: diagnoses, medical history, medications and schedules, allergies, treating clinicians, and preferred hospital.
• Communication: how the person communicates (speech, sign, devices) and how to interpret distress.
• Daily routine: schedule, personal-care needs, sleep, and tasks the person can do or loves to do.
• Food: diet, favourite and disliked foods, allergies, and any food–medication interactions.
• Triggers and comfort: what upsets the person, which situations to avoid, and what soothes them.
• Benefits and legal: ODSP, Passport, RDSP, trust and guardianship or POA details, and where the documents live.
• The vision: the parent’s and person’s hopes for their future life.

Ontario also publishes an emergency preparedness guide for people with disabilities, advising that households be self-reliant for at least three days and build an individualized emergency plan and kit.

Practical tools and where to get help in Ontario

• Partners for Planning (P4P) / Planning Network: free webcasts, resources and fee-for-service independent facilitation; the digitized Safe and Secure workbook; and the Future Planning Tool (covering housing, legal decision-making, finances and RDSP, personal networks and benefits for Ontario and B.C.). P4P convenes the RDSP Action Coalition of Ontario and a Professional Services Directory of vetted financial and estate professionals.
• PLAN (Planned Lifetime Advocacy Network): personal support network development and person-centred planning.
• Family Alliance Ontario: a network of autonomous family networks (founded 1997); publishes Safe & Secure – Seven Steps on the Path to a Good Life for People with a Disability and hosts a directory to find a family network locally (including the Waterloo Region Family Network, relevant to AIM’s service area).
• Community Living organizations (Community Living Ontario and local affiliates such as Community Living North Halton): planning support, family networks, and residential services.
• Developmental Services Ontario (DSO): eligibility, application, service registry, housing navigators, and the Housing Toolkit.
• Microboards Ontario / PooranLaw / Vela Canada: for families considering incorporating a Microboard.
• MCCSS-funded resources: Passport funding (usable for person-directed planning), person-directed planning guides, and the Knowledge Translation and Transfer (KTT) Hub.
• The Ontario Caregiver Organization: free counselling, peer support and respite navigation for caregivers.

The emotional side, handled with care

Future planning is grief work done in advance. Canadian data confirm the strain: per Palmeter, O’Donnell & Smith (PHAC, May 2025), analyzing the 2018 GSS, caregivers of people with developmental disabilities report poorer general and mental health than non-caregivers; “about two-thirds of DD caregivers reported feeling worried or anxious, or tired and almost half reported unmet support needs,” yet “a significantly higher proportion of DD caregivers described their caregiving experiences as rewarding.” Naming both truths matters.

• Guilt and grief are the normal texture of this work, not a sign of failing. Writing a letter of intent is itself “a very emotional experience” because it requires imagining the child’s life without the parent.
• Sibling roles and expectations must be discussed explicitly, not assumed. Heller & Kramer (2009) found that 38% of siblings anticipated becoming the primary caregiver to their sibling with a developmental disability. Burke, Taylor, Urbano & Hodapp (2012), surveying 757 siblings, found siblings were more likely to expect this role “if they were female, had closer relationships with and lived closer to their brother or sister… and were the lone sibling without a disability” — but few families had actually made plans or involved siblings in them. The siblings’ expressed needs were concrete: support groups, training on how to assume caregiving, financial support, and printed material on making future plans. The planning goal is not to conscript a sibling but to clarify what each person is (and is not) willing to do, and to build a wider network so no single person carries everything. See Adult Siblings of People with Developmental Disabilities: A Guide for Ontario Families.
• Starting the conversation: small, staged steps — a first family meeting, a draft vision, registering with DSO, writing a one-page emergency profile — turn an overwhelming question into manageable tasks and reduce dread.

Staged, concrete next steps

Stage 1 — this month (regardless of the person’s age or the caregiver’s health):

• Register (or confirm registration) with your regional DSO; if the person is 16–17, begin the application now.
• Draft a one-page emergency profile or letter of intent covering medical, communication, routine, food, triggers and key contacts. Tell at least two people where it lives. If the primary caregiver has any acute health event, expand this to a full binder immediately.

Stage 2 — next 6–12 months:

• Convene a first family or network conversation. Name the people who already love the person and invite them into a circle of support.
• Engage an independent facilitator (via OIFN or P4P) if the family wants help building the vision and network; use Passport funding for person-directed planning where eligible.
• Confirm the financial and legal scaffolding is in motion (RDSP opened, will and Henson trust drafted, POA or guardianship reviewed) — see AIM’s guides on Henson Trusts and Estate Planning for a Family Member on ODSP in Ontario and Legal Decision-Making in Ontario: Capacity, Powers of Attorney and Guardianship — A Family Guide.

Stage 3 — ongoing (annual review):

• Update the letter of intent and DSO file every year and after any major change (the family’s care capacity affects DSO priority).
• Begin graduated residential transition — respite stays, overnights, skill-building — well before it is needed; treat the 20+ year housing waitlist as a planning reality, not a last-minute option.
• Consider formalizing the network as a Microboard if the family wants a durable, legally accountable structure to manage funding and safeguard relationships for life.

Thresholds that should raise the urgency: the primary caregiver turning 65–70; any hospitalization or new diagnosis of the caregiver; the person’s own frailty markers appearing (common from age 50); or the loss of a co-caregiving spouse. Any of these should move items from “planned someday” to “acted on now.”

Grey areas and points of confusion

• Population counts differ by method. The Ministry’s ~62,000 (2012, 0.5% prevalence) and H-CARDD’s 66,484 (2009–10, 0.78%) reflect different methods; both are dated, and no precise current census of Ontario adults with developmental disabilities is published.
• Waitlist figures are inconsistent and imperfect. The Ombudsman explicitly found “no comprehensive accurate count” of people waiting for supportive living, average wait times, or numbers served, and noted available figures are “inconsistent and not generally available to the public.” The widely cited “52,000–53,000” total and “28,000 for housing” figures come from advocacy and ministry sources and should be read as order-of-magnitude, not audited.
• Model effectiveness is under-evidenced. Circles of support, PLAN networks and Microboards are widely endorsed and backed by decades of practice and compelling case stories, but rigorous outcome research (for example, controlled long-term studies showing they prevent crisis placement or improve wellbeing) is thin. Their value rests largely on practice wisdom and qualitative accounts rather than strong quantitative outcome data.
• The aging-caregiver headcount is partly a projection. The 11,200 (caregiver 60+) figure is from an internal 2023 MCCSS briefing cited by the Ombudsman; the “17,400 within five years” is a projection, not an observed count.

How current is this, and what to double-check

• Most current and most authoritative: the Ombudsman’s Lost in Transition (November 2025) and the PHAC 2018-GSS analysis (published May 2025) are recent and primary. The Ombudsman’s hospitalization figure (124 adults, December 2024) is point-in-time.
• Aging, frailty and prevalence data are older. The H-CARDD Atlas cohort (2009–2010) and aging-profile findings, while still the best population-based Ontario data, are more than a decade old and may understate today’s numbers as the population ages and life expectancy rises. Treat them as potentially stale.
• US context is labelled and not treated as Canadian. Some frequently cited “80% live at home” and “25% of caregivers over 60” figures are US estimates (for example, The Arc; Heller 2011) and are not used here as Ontario figures.
• “Letter of intent” guidance is largely US-sourced. The concept is universal, but many detailed templates come from US special-needs-planning firms; Ontario families should align the financial and legal sections with Ontario instruments (ODSP, RDSP, Henson trust, Ontario POA or guardianship) per AIM’s dedicated guides.
• Terminology: this guide uses person-first “adults with a developmental disability,” consistent with Ontario’s legal and funding language under the Services and Supports to Promote the Social Inclusion of Persons with Developmental Disabilities Act, 2008 (SIPDDA) and DSO/Passport. Research literature often uses “intellectual and developmental disabilities (IDD)”; the terms are treated as equivalent here.
• Scope boundaries: trusts and estate mechanics, legal-capacity and decision-making mechanics, and housing and residential models are referenced at a high level only and are covered by AIM’s separate guides.

This is general information for families, not legal or financial advice; align the details with your own situation and current Ontario rules before acting.
