The Medical Expense Tax Credit (METC) is a non-refundable federal tax credit for medical expenses that exceed a minimum threshold. For 2026, the threshold is the lesser of $2,814 or 3% of net income (line 23600). Expenses above the threshold are creditable at 15% federally. Provinces provide additional credits at their lowest provincial rate on the same eligible expenses. The METC is claimed on line 33099 (for the claimant and their dependants) of the T1 return.
What medical expenses qualify for the METC?
The list of eligible medical expenses is set out in Income Tax Regulation 5700 and in the Income Tax Act s.118.2(2). It includes: prescription drugs and medications; dental procedures (other than cosmetic work); vision care including glasses and contact lenses; physiotherapy; licensed medical practitioners’ fees; ambulance services; wheelchairs, crutches, and orthopedic devices; hearing aids and cochlear implants; home oxygen; attendant care costs; nursing home care; and many other prescribed devices and services. Over-the-counter medications (vitamins, supplements, non-prescription drugs) are generally not eligible unless prescribed by a medical practitioner and recorded in a pharmacist’s or pharmacy’s register.
How the METC is calculated
The threshold and credit rate
Step 1: Total eligible medical expenses paid in the 12-month period ending in the tax year (or any 12-month period the taxpayer chooses that ends in the tax year). Step 2: Subtract the threshold — the lesser of $2,814 (2026) or 3% of the claimant’s net income. Step 3: Multiply the remainder by 15% (federal) plus the provincial rate. For an Ontario resident with $12,000 of eligible expenses and $60,000 of net income: threshold = min($2,814, 3% x $60,000) = min($2,814, $1,800) = $1,800. Creditable expenses = $12,000 minus $1,800 = $10,200. Federal credit = 15% x $10,200 = $1,530. Ontario credit = 5.05% x $10,200 = $515. Total = $2,045 in combined tax reduction.
Claiming for a family member
Medical expenses for a spouse or common-law partner and for dependent children under 18 are claimed together on line 33099. For dependent children aged 18 or older, dependent parents, grandparents, siblings, aunts, uncles, nieces, or nephews, medical expenses are claimed separately on line 33199, with a threshold equal to the lesser of $2,814 or 3% of the dependant’s own net income. Claiming for dependants with low income (such as a dependent parent with low retirement income) is often highly valuable: if the dependant’s 3% of net income is very small, nearly all their medical expenses exceed the threshold.
The 12-month period election
Medical expenses can be claimed for any 12-month period ending in the tax year. If a large expense was paid in December 2024, the taxpayer can choose a 12-month period running January 2024 to December 2024, or February 2024 to January 2025 (which would include January 2025 expenses in the 2024 return), or any other 12-month window ending in 2024. This flexibility allows taxpayers to maximise the credit by timing the period to include the largest cluster of expenses. Expenses must not be claimed in two consecutive tax years; the same expense cannot appear in two different years’ returns.
Verified against source
The 2026 METC threshold of $2,814 is confirmed from the CRA chart of indexed amounts. The list of eligible medical expenses is confirmed from Income Tax Act s.118.2(2) and CRA’s Medical Expenses page (canada.ca/en/revenue-agency/services/tax/individuals/topics/about-your-tax-return/tax-return/completing-a-tax-return/deductions-credits-expenses/lines-33099-33199-eligible-medical-expenses). The provincial credit rates are confirmed from the Ontario T1 guide and provincial tax schedules. These values were verified in April 2026.
Key eligible and non-eligible expenses
| Eligible | Not eligible |
|---|---|
| Prescription drugs (pharmacist-registered) | Over-the-counter medications (general) |
| Dental (non-cosmetic) | Cosmetic procedures (teeth whitening, Botox) |
| Physiotherapy (licensed) | Gym memberships or fitness classes |
| Eyeglasses, contact lenses (prescription) | Sunglasses without prescription |
| Hearing aids | Personal care items |
| Wheelchairs, orthotics | Vitamins and supplements (generally) |
| Attendant care for a disabled person | General domestic help |
| Nursing home care | Room and board in assisted living (non-medical) |
| Medical travel (50+ km to nearest service) | Travel for non-medical reasons |
Disability supports deduction vs METC
Attendant care and disability-related expenses may be deductible under the Disability Supports Deduction (line 21500) instead of or in addition to the METC. The Disability Supports Deduction applies only to the person with the disability and is limited to earned income; it is a deduction (not a credit) that reduces net income. The METC is a credit on the lesser of actual expenses or net income. For high-income claimants, the Disability Supports Deduction may produce a larger tax saving than the METC. However, the same expenses cannot be claimed under both; CRA requires the claimant to choose the more beneficial treatment, and in many cases claiming attendant care under line 21500 is optimal.
Travel expenses for medical care
If the nearest specialist or facility offering the required medical service is more than 40 kilometres from the patient’s home, reasonable travel expenses are eligible for the METC. Eligible expenses include transportation (bus, train, taxi, or privately owned vehicle at a prescribed per-kilometre rate) and accommodation (reasonable hotel costs). If the travel is 80 kilometres or more, meals at a flat rate of $23 per meal (three meals per day for each person, including the accompanying attendant if one was required) are also eligible. These amounts apply to travel for medical appointments and procedures within Canada; foreign medical travel is more complex and requires that the medical service be unavailable in Canada.
Claiming medical expenses for the optimal year
Because the METC threshold is the lesser of $2,814 or 3% of net income, claimants with lower incomes may have a smaller effective threshold. A claimant with $30,000 of net income has a threshold of min($2,814, $900) = $900. The first dollar of eligible expenses above $900 generates a credit. Clustering expenses in a single 12-month period maximises the benefit: two years of expenses, if staggered, can produce a single large credit in one year rather than two small credits in separate years. For example, having major dental work in December and glasses in January creates an opportunity to choose a 12-month window (December 1 to November 30) that includes both, rather than splitting them across two tax years.
Provincial METC supplements
All provinces provide an additional METC credit at their lowest marginal rate on the same eligible expenses. Ontario’s provincial rate is 5.05%, which adds approximately $515 in provincial tax savings on $10,200 of creditable expenses. Quebec provides a refundable medical expense credit (Refundable Medical Expense Supplement) for low-income Quebecers who do not owe enough tax to use the non-refundable credit. Manitoba provides a refundable Medical Expense Supplement at the provincial level. These provincial supplements are calculated automatically on the provincial tax schedules (Form ON428 for Ontario, Form TP-1 for Quebec) when the METC is claimed federally.
