Disability Tax Credit renewal
Some DTC approvals have an end date, shown on your notice of determination. The CRA reminds you on your notice of assessment a year before and in the year it expires; re-apply then so the Canada Disability Benefit, RDSP grants and other supports aren’t interrupted.
No upcoming dates match. Try “Anywhere in Canada” or “Everyone”.
Every date was checked on an official government page (linked on each one). Dates marked proposed were announced but aren’t law yet, so they could change. Past dates drop off automatically.
Not a government site. Always confirm with Service Canada, the CRA or your province.
