The DTC is a non-refundable tax credit that helps people with disabilities and their supporting family members reduce the amount of income tax they may have to pay. For children with autism, the application focuses on how the diagnosis affects their ability to perform daily tasks compared to peers of the same age. It is also the gateway to the Registered Disability Savings Plan (RDSP).
A family with a 5-year-old child who is non-verbal and requires constant supervision for safety applied for the DTC. Their pediatrician completed the T2201 form, detailing how the child's communication and social impairments constitute a "marked restriction." Once approved, the family was able to claim the disability amount on their taxes and open an RDSP with government matching grants.

How long do families wait for Ontario autism services?
VerifiedOntario autism wait times for core clinical services now exceed 5+ years (Ontario Autism Coalition, July 2026). Funding invitations are currently reaching families who registered in August 2021 (Ontario Autism Coalition, July 2026 (reported from community intake)).

Is the Ontario Autism Program underfunded?
VerifiedYes. The Financial Accountability Office (FAO) determined that $1.35 billion annually is needed to serve all registered children at 2018-19 service levels. The 2026-27 Ontario Budget allocated $965 million, leaving an estimated $385M+ annual shortfall. This gap is the primary driver of the perpetual 91,974+ child waitlist.
