1. Moving expenses
You can only claim moving expenses that your employer hasn't already reimbursed you for. If you have been reimbursed for some or all of your moving expenses, you must include this as income on your tax return.
2. Public transit costs
You can't claim day passes, tokens or tickets. You can only claim a monthly or annual transit pass.
3. Interest paid on student loans
You can only claim interest on student loans made to you under the Canada Student Loans Act, the Canada Student Financial Assistance Act, or similar provincial or territorial government laws. You can't claim interest paid on any other kind of loan, even if it is to finance your education. Example: a line of credit. You can’t transfer the claim to anyone else, even if they paid the interest on the loan.
4. Union and professional dues
Your employer may withhold dues from your pay. This will be noted on your T4 slip and you can claim a corresponding deduction. You may also get a receipt for these dues from your union or association. But you can only claim the deduction once. If you have been reimbursed for dues paid, you cannot claim any of the dues as a deduction unless your employer has included them as a taxable benefit on your T4.
5. Other deductions (line 232)
You can only use line 232 to claim allowable amounts not deducted anywhere else on your return. You can't use this line to claim personal or living expenses that are not legitimate tax deductions. Examples: funeral costs, wedding costs, legal fees paid for separation or divorce agreements.
