# DTC for Children with Type 1 Diabetes: A Parent's Guide
CRA Functional Category: Life-Sustaining Therapy — therapy that is needed to support a vital function and that is required at least 3 times per week for an average of at least 14 hours per week.
Type 1 diabetes is one of the most clearly defined qualifying conditions for the Disability Tax Credit. CRA recognizes insulin therapy as life-sustaining therapy, and the time spent managing your child's diabetes almost always exceeds the 14-hour weekly threshold.
For the general diabetes DTC guide, see Type 1 Diabetes & Intensive Insulin Therapy. For an overview of all child-related DTC benefits, see our Child Disability Benefits page.
How CRA Evaluates Type 1 Diabetes in Children
CRA evaluates Type 1 diabetes under the life-sustaining therapy category. To qualify, your child's therapy must:
- Be essential to sustain a vital function (insulin is required to sustain life)
- Be needed at least 3 times per week (insulin is needed multiple times daily)
- Require an average of at least 14 hours per week of therapy time
What Counts Toward the 14 Hours
CRA allows you to count time spent on activities that are directly related to the therapy and would not be needed but for the condition:
| Activity | Typical Time |
|---|---|
| Blood glucose monitoring (6-10+ checks/day) | 3-5 min each |
| Insulin dose calculation and administration | 5-10 min each |
| CGM calibration and monitoring | Ongoing throughout day |
| Carbohydrate counting for every meal/snack | 5-10 min each |
| Treating hypoglycemic episodes | 15-30 min each |
| Treating hyperglycemic episodes | 15-30 min each |
| Insulin pump site changes (every 2-3 days) | 15-20 min each |
| Nighttime blood sugar checks | 10-15 min each |
| Preparing diabetes supplies | 10-15 min daily |
For most children with Type 1 diabetes, the total easily exceeds 14 hours per week — often reaching 20-25+ hours when all therapy-related activities are properly documented.
What Does NOT Count
CRA excludes time spent on activities that would be done regardless of the condition:
- Meal preparation (but carb counting does count)
- General exercise (but exercise-related glucose management counts)
- Travel to medical appointments
- Dietary restrictions that don't require active management
What Your Child's Practitioner Needs to Document
Who Can Sign
| Practitioner | Can Sign for Life-Sustaining Therapy? |
|---|---|
| Paediatric endocrinologist | Yes (recommended) |
| Paediatrician | Yes |
| Family physician | Yes |
| Nurse practitioner | Yes |
Key Documentation Points
The practitioner must certify:
- The therapy is life-sustaining — insulin is required to sustain life
- Frequency: At least 3 times per week (daily for T1D)
- Duration: At least 14 hours per week of therapy-related activities
- Onset date: When the child was diagnosed (this determines retroactive eligibility)
Important: The practitioner should document the total time spent on all therapy-related activities, not just injection/pump time. Many practitioners underestimate the total by only counting injection time.
The Combined Benefits for Families
Type 1 diabetes DTC approvals for children are typically strong and long-lasting:
| Benefit | Estimated Amount |
|---|---|
| DTC retroactive refund (from diagnosis date, up to 10 years) | $30,000–$40,000+ |
| Child Disability Benefit (tax-free, retroactive with written request) | $20,000–$34,000 |
| RDSP government contributions | Up to $4,500/year |
| Combined total | $50,000–$75,000+ |
Ongoing Annual Benefits
Beyond the retroactive lump sum, your family receives ongoing benefits every year:
- Annual DTC tax reduction: ~$3,000–$4,000/year
- Monthly CDB payments: Up to ~$284/month (tax-free)
- RDSP grants: Up to $3,500/year in matching grants
Common Mistakes in T1D Applications
- Underestimating therapy time — Only counting injection time, not the full scope of management activities
- Not including nighttime checks — Parents who check blood sugar overnight should include this time
- CGM confusion — CGM monitoring time counts, even though the device is continuous
- Pump vs. injection framing — Both qualify; pump management often takes more time, not less
- Missing the onset date — The diagnosis date determines how far back your retroactive claim goes
Insulin Pump and CGM Users
If your child uses an insulin pump and/or continuous glucose monitor:
- Pump site changes (every 2-3 days): 15-20 minutes each
- CGM sensor changes (every 7-14 days): 10-15 minutes each
- CGM alarm responses: Multiple times daily, 5-10 minutes each
- Pump adjustments: Basal rate changes, bolus calculations throughout the day
- Data review and pattern management: 15-30 minutes daily
Technology does not reduce the total therapy time — it often increases it due to device management, troubleshooting, and data review.
When to Apply
Apply as soon as your child is diagnosed with Type 1 diabetes. Key considerations:
- Diagnosis date = onset date: The practitioner should certify the onset as the diagnosis date
- No waiting period: You don't need to wait for the condition to be "established"
- Retroactive from diagnosis: If your child was diagnosed 5 years ago and you haven't applied, you can claim 5 years of retroactive benefits
- Indefinite approval: T1D DTC approvals are typically indefinite (the condition is lifelong)
