For many Canadians, tax season follows the same routine every year: enter your income slips, claim the standard deductions and hope for a refund. But hidden within the rules of the Canada Revenue Agency are several legitimate credits and deductions that often surprise even experienced taxpayers.
Financial columnist Christopher Liew says the tax system allows more flexibility than many people realize — provided the expense is reasonable, directly connected to earning income or medical needs, and backed by proper documentation.
One of the most surprising examples involves gluten-free groceries for people diagnosed with celiac disease. The CRA may allow taxpayers to claim the extra cost of gluten-free products compared with regular alternatives under the Medical Expense Tax Credit. That means not the full grocery bill, but the price difference between standard and gluten-free items. A doctor’s confirmation and detailed receipts are typically required.
Medical cannabis may also qualify. If prescribed by an authorized health-care practitioner and purchased from a federally licensed seller, eligible costs can be included as medical expenses. Many Canadians remain unaware that certain medically authorized cannabis purchases can be treated similarly to other health-related expenses.
For individuals who rely on trained service animals, some costs linked to the animal’s care may also be claimable. This can include food, veterinary expenses and related costs, but only when the animal meets CRA eligibility standards for assisting with a recognized medical condition.
Another lesser-known medical claim is the cost of a wig for abnormal hair loss caused by illness, injury or treatment such as chemotherapy. When supported by proper medical documentation, the expense may qualify.
Self-employed Canadians may have access to even broader deductions, though they must meet stricter tests. Expenses such as professional makeup for performers or creators, music subscriptions used by fitness instructors, or niche consulting services may qualify if they are directly tied to generating income and properly recorded. Personal use expenses, however, do not qualify simply because someone works independently.
Experts stress that unusual does not mean automatic. Claims must be truthful, reasonable and well documented. Receipts, invoices and a clear business or medical purpose are essential, especially if the return is reviewed.
The broader lesson for taxpayers is simple: many people focus only on the obvious deductions and overlook legitimate savings opportunities. Understanding the rules — and keeping organized records — can make a meaningful difference at tax time.
