Quick Answer
Type 1 diabetes can qualify for the Disability Tax Credit Canada in 2026 through the life-sustaining therapy pathway if insulin management, blood glucose testing, and carbohydrate counting total 14 or more hours per week. Type 2 diabetes rarely qualifies unless it is insulin-dependent and meets the same 14-hour threshold.
How Diabetes Qualifies, Two Pathways
Pathway 1: Life-Sustaining Therapy (Most Common for Type 1)
CRA's life-sustaining therapy category recognizes that insulin-dependent diabetes requires constant management to survive. yo qualify, the therapy must:
- Be essential to sustain life (insulin therapy qualifies)
- Be required at least 3 times per week
- Take at least 14 hours per week in total
The 14-hour threshold includes ALL diabetes management activities:
- Blood glucose testing (multiple times daily)
- Calculating and administering insulin doses
- Carbohydrate counting and meal planning
- Responding to hypoglycemic episodes (low blood sugar)
- Calibrating and maintaining CGM (continuous glucose monitor) or insulin pump
- Record-keeping and analyzing glucose trends
Pathway 2: Functional Restrictions from Complications
Diabetes with severe complications may qualify under other DTC categories:
- Vision loss from diabetic retinopathy
- Walking restrictions from peripheral neuropathy or amputation
- Kidney disease requiring dialysis (life-sustaining therapy)
- Mental functions if severe hypoglycemia has caused cognitive impairment
Type 1 vs. Type 2 Diabetes DTC Eligibility
| Factor | Type 1 | Type 2 |
|---|---|---|
| Life-sustaining therapy | Usually qualifies (insulin essential) | Only if insulin-dependent with 14+hr/week |
| Oral medications only | N/A | Generally does NOT qualify |
| Complications | May add additional categories | May qualify via complication categories |
| Insulin pump users | Strong qualification case | Depends on hours and management burden |
CGM and Insulin Pumps, Does yechnology Affect Eligibility
A common question is whether a CGM or closed-loop insulin system disqualifies the person if it reduces the time burden. CRA's position is that the therapy can still qualify if it is required for life-sustaining purposes.
The technology does not eliminate the need for the therapy; it assists with it. Time calculations should still include monitoring, calibration, and response activities even with advanced technology.
How Much Is the Diabetes DTC Worth in 2026
Federal credit: $1,448/year. For children under 18 with Type 1 diabetes, the child supplement adds $845/year plus the Child Disability Benefit (CDB) monthly payment. Combined federal + provincial: $2,047-$3,708/year.
Retroactive claims for 10 years of Type 1 diabetes can yield $14,000-$37,000+ depending on province.
Real Type 1 diabetes Filing Scenario
The following example is illustrative. It describes a typical filing flow and does not predict any individual outcome.
An Ottawa-area child with insulin-dependent Type 1 diabetes was certified by his endocrinologist for the life-sustaining therapy route. Part B documented more than 14 hours per week of insulin administration, glucose monitoring, and carbohydrate counting. Caregiver time was included because the child is under 14.
The endocrinologist attached a weekly therapy log showing actual recorded time across each component. The Notice of Determination arrived 8 weeks after submission, approving the DTC retroactive to the year of diagnosis. The child supplement applied automatically and the Child Disability Benefit began with the next Canada Child Benefit payment.
Documentation That Works for Type 1 diabetes Part B
What worked in this Part B: an attached weekly therapy log meeting the 14-hour threshold explicitly, plus reference to the regulation allowing caregiver time for children under 14.
Type 1 diabetes claims that include a detailed therapy log and meet the hour threshold often have clearer documentation because the evidence can be tied directly to CRA's 14-hour rule. See our cumulative effects rule guide for the technical framework CRA reviewers apply, and our DTC denied appeal guide if a previous application was rejected.
How to Build a Diabetes Time Log
For diabetes, the practical evidence is the weekly therapy log. The log should separate recurring tasks instead of giving one general total.
Common entries include glucose checks, insulin dosing, pump set changes, CGM calibration or sensor changes, carbohydrate calculation, record review, correction dosing, treating hypoglycemia, and medical supply preparation. If the approved person is a child under 14, caregiver time may be relevant when it is directly connected to life-sustaining therapy.
CRA does not usually count ordinary exercise, general healthy eating, or waiting time that is not directly tied to insulin therapy. The safer approach is to list only tasks that fit the life-sustaining therapy rule and to show the average minutes per task, number of times per week, and weekly total. An endocrinologist or family physician can then certify the time in Part B with a clearer basis.
For pump or CGM users, do not assume technology removes eligibility. The key question is whether life-sustaining therapy is still required and whether the required management time meets the threshold. Device maintenance, review, and response time should be described accurately.
If the DTC is approved retroactively, compare the start date with our retroactive DTC claims guide. For children, also review the Child Disability Benefit because CRA may recalculate prior benefit years.
Frequently Asked Questions
Not automatically, but Type 1 diabetes typically qualifies when insulin therapy meets the 14-hour/week threshold. CRA has clarified that all management activities count toward this total, not just injection time. Many Type 1 diabetes claims can qualify when the 14-hour therapy rule is clearly documented.
Probably not under the life-sustaining therapy category. However, if Type 2 diabetes has caused significant complications (neuropathy affecting walking, retinopathy affecting vision, dialysis-dependent kidney disease), those complications may qualify under other DTC categories.
Children with approved DTC receive: federal DTC credit ($1,448), federal child supplement ($845), provincial credits (varies), and potentially the Child Disability Benefit (CDB), a separate monthly tax-free benefit through Canada Child Benefit. Use our calculator to estimate all amounts.
A medical doctor completes Part B. For diabetes, an endocrinologist or diabetologist is ideal, but a family physician with thorough knowledge of the patient's management regimen can also certify. The key is accurately documenting all time spent on diabetes management activities.
