Only the “Form T2201” is sent to the Canada Revenue Agency, once the doctor completes and signs, than you are responsible for submitting the form.
The questions in the form “T2201” does not base any questions on whether you’re able to work.
It only asks about how your “Basic Activities of Daily Living”(BADL) are/is affected, and falls into the outlined eligibility criteria.
You only need 1 “Basic Activity of Daily Living” to qualify to be eligible for the Disability Tax Credit, that includes a section for “Cumulative Effects”. None of the other BADL’s sections have to be completed except the one/s you’re applying for.
If the CRA needs more information to make a decision they will write a letter to the Doctor that completed the form. It’s called a “Clarification Letter”.
