Type 1 diabetes is one of the most clearly qualifying conditions for the Disability Tax Credit under CRA's life-sustaining therapy category. If you or your child manages Type 1 diabetes with insulin therapy, you are very likely eligible for the DTC — and potentially significant retroactive refunds.
The Life-Sustaining Therapy Category
CRA defines life-sustaining therapy as therapy that is required to support a vital function and that must be administered at least three times per week. The total time spent on the therapy — including preparation, administration, and recovery — must average at least 14 hours per week.
For Type 1 diabetes, this includes all time spent on:
- Blood glucose monitoring (testing, recording, analyzing results)
- Insulin administration (injections or pump management)
- Carbohydrate counting and meal planning
- Managing insulin pump settings and supplies
- Treating and recovering from hypoglycemic episodes
- Medical appointments related to diabetes management
- Adjusting insulin doses based on activity, illness, or stress
When all diabetes management activities are properly documented, most Type 1 diabetes patients easily meet the 14-hour weekly threshold. The key is ensuring the T2201 form accounts for ALL time spent on therapy-related activities, not just insulin injections.
Common Documentation Mistakes
Even though Type 1 diabetes is a strong qualifying condition, applications are still sometimes denied due to documentation errors. The most common mistakes include:
- Only counting injection time (not total management time)
- Not specifying the frequency of blood glucose monitoring
- Failing to document time spent on carbohydrate counting
- Not including time for hypoglycemic episode management
- Using a medical practitioner who isn't familiar with the 14-hour calculation
Children with Type 1 Diabetes
Children with Type 1 diabetes are strong candidates for the DTC, which also unlocks the Child Disability Benefit (CDB). Parents should note that the time they spend managing their child's diabetes counts toward the 14-hour threshold — including overnight blood sugar checks, school communication about diabetes management, and emergency preparedness.
At My Benefits Canada, we work with your medical practitioner to ensure the T2201 accurately captures the full scope of diabetes management activities. Our goal is a thorough, well-documented application that clearly meets CRA's criteria.
