Celiac Sentry

Harwick Digital

About this app

If you have Celiac disease in Canada, you may be able to claim the extra cost of gluten-free food as a medical expense on line 33099 of your T1 return. Most Canadians never claim it — not because they're ineligible, but because the paperwork is overwhelming.
Celiac Sentry fixes that.
Built by a Canadian family living with Celiac disease, for every Canadian family living with Celiac disease.

🧮 STATISTICS CANADA REFERENCE PRICES
Pre-loaded provincial average prices for bread, pasta, flour, cereal and more, so you have a defensible reference price from day one. Source: Statistics Canada, Table 18-10-0245-01: https://www150.statcan.gc.ca/t1/tbl1/en/tv.action?pid=1810024502

📅 SMART CLAIM PERIOD OPTIMIZER
You may claim any 12-month period ending in the tax year. Celiac Sentry helps you find the window that maximizes your eligible amount.

ELIGIBILITY
──────────────────────────────
To claim GF food expenses you need a formal Celiac disease diagnosis and a letter from your doctor. Celiac Sentry handles the records — your doctor handles the letter.
