Families raising a child with autism or an intellectual disability, or supporting an adult relative with one, are often eligible for a meaningful number of federal and provincial supports. The trouble is that no one hands you the list. This guide is a plain-language overview of where to look, organized by who pays and what each program is meant to cover.
One note before we start. Eligibility rules and dollar amounts change every year, so the figures themselves are not in this guide. Verify current amounts and forms with the program directly: Retraite Québec for the Quebec child supplements, Revenu Québec for provincial tax credits, Service Canada for federal benefits, and the Canada Revenue Agency for federal tax credits. The links and forms on those sites are the authoritative versions.
1. Federal: the Disability Tax Credit (DTC)
The Disability Tax Credit is the gateway to most other federal supports. It is a non-refundable tax credit, but its real value is that it qualifies the family for a series of additional programs. To apply, a medical practitioner certifies that the person has a severe and prolonged impairment using federal Form T2201.
Once the DTC is approved, the family becomes eligible for:
- Child Disability Benefit (CDB). A monthly amount added to the Canada Child Benefit for families with a child under 18 who qualifies for the DTC.
- Registered Disability Savings Plan (RDSP). A long-term savings vehicle with federal contributions (the Canada Disability Savings Grant) and, for low-income families, additional bond payments. The RDSP is one of the more powerful long-term tools available, especially for parents thinking about adult life for a child with a disability.
- Disability supports deduction for working-age individuals.
If you do nothing else, get the DTC application started. Many of the other doors do not open without it.
2. Quebec: the Supplement for Handicapped Children
Retraite Québec administers the Supplément pour enfant handicapé (Supplement for Handicapped Children), a monthly amount paid to families of a child under 18 with a significant disability. It is provincial, separate from the federal CDB, and a family can receive both.
For children whose disability requires exceptional care, Retraite Québec also pays the Supplément pour enfant handicapé nécessitant des soins exceptionnels (SEHNSE), a higher monthly amount. SEHNSE has stricter eligibility criteria and requires documentation from the medical team.
Both supplements are applied for through Retraite Québec. The form requires medical documentation, and most pediatric clinics are familiar with the process.
3. Quebec: tax credits that compound
Quebec has several refundable and non-refundable tax credits that often apply alongside the federal ones:
- Tax credit for a severe and prolonged impairment in mental or physical functions: provincial counterpart of the federal DTC.
- Tax credit for caregivers: for a family member providing care to a person with a disability, sometimes available even when the caregiver does not live with the person being cared for.
- Refundable tax credit for medical expenses: broader than people often think, and worth checking against private therapy costs (speech therapy, occupational therapy, behavioural intervention).
- Refundable tax credit for childcare expenses: with higher limits for a child with a disability.
The exact way these stack depends on family income, household composition, and what other programs are already in place. An accountant who works with families of children with disabilities can usually find more than a generalist can.
4. Adult intellectual disability and autism: income support
For adults whose disability prevents employment, the main provincial program is the Programme de solidarité sociale (Social Solidarity Program), specifically the stream for people with a "severely limiting condition" (contrainte sévère à l'emploi). This is administered by the Ministère de l'Emploi et de la Solidarité sociale and provides a higher monthly benefit than regular social assistance, plus access to other supports.
Eligibility is established by medical documentation and is usually permanent once granted. For young adults with autism or an intellectual disability who are aging out of the youth-services system, this is often the income foundation that everything else is built on.
5. Services rather than money: CRDITED and the public network
Some of the most valuable supports are not cash transfers. The Quebec public network funds specialized services for autism and intellectual disability, often delivered through what was historically called CRDITED and is now integrated into each region's CIUSSS or CISSS. These include early intervention, behavioural support, residential services, day programs, and respite care.
Access is through the regional CIUSSS or CISSS, usually after a referral from a CLSC or a pediatric clinic. Wait times are real, and some families combine the public service with private therapy paid for partly through the tax credits above.
6. Respite for caregivers
The Chèque emploi-service program lets families hire their own respite worker and have part of the cost covered by the public system. It is administered through the CLSC and the Centre de traitement after an evaluation of need. For families burning out, this is one of the more practical levers, because it preserves choice over who provides the care.
Some community organizations also run subsidized respite programs, including weekend and overnight respite for children with significant needs. The CIUSSS social worker can usually point to the ones that exist in your area.
7. Education: a brief note on the IEP/PEI
Although it is not a subsidy, the school-side equivalent for a child with autism or an intellectual disability is the Individualized Education Plan (PEI in French, "plan d'intervention"). This document, developed by the school team and the family, sets out accommodations, services, and goals for the school year. It is the backbone of how special-needs services are delivered inside the public school system.
How to start
If you are reading this because you have a recent diagnosis or are about to, the practical sequence usually looks like this:
- Apply for the federal Disability Tax Credit first. The medical certification is the same paperwork that supports several of the other applications.
- Apply for the Supplément pour enfant handicapé through Retraite Québec for any child under 18.
- Open an RDSP as soon as the DTC is approved, even if you can only contribute a small amount. The federal contributions are the largest part of its value.
- Talk to an accountant who knows disability files, especially before tax filing season. The credits stack in non-obvious ways.
- Get on the CIUSSS waiting list for specialized services as soon as you have a diagnosis. The wait happens whether you are on the list or not.
