In Ontario, Canada, dentures may be tax-deductible under certain conditions. The Canada Revenue Agency (CRA) allows individuals to claim a non-refundable tax credit for medical expenses, which includes dentures, through the Medical Expense Tax Credit (METC). To qualify, the total medical expenses must exceed the lesser of 3% of your net income or a set base amount specified by the CRA. It’s important to keep all receipts and documentation for your dental expenses. Since tax laws and regulations can change, it’s recommended to consult with a tax professional or refer to the CRA’s most current guidelines for detailed information on medical expense deductions.
