What is the highest cash back rate available in Canada?
+
Rates change as issuers revise their cards, so we don't quote them here. /ca/credit-cards/cash-back lists current cards with the rates from each card's record. Remember that category rates depend on the merchant's category code.
Is cash back taxable in Canada?
+
We don't give tax advice. The CRA guidance we cite covers one situation: points employees earn on employer-reimbursed business expenses. Under the CRA's administrative policy, redeeming those points isn't a taxable employment benefit if the employer doesn't control them, they aren't converted to cash, and the arrangement isn't a form of pay or tax avoidance. American Express's Membership Rewards terms also say there may be tax implications and that you are responsible for your own tax obligations. For your situation, ask the CRA or a tax professional.
How many cash back cards should I have?
+
There's no set number. FCAC advises applying for credit only when you need it and avoiding several applications close together, because each is a hard inquiry on your credit report.
Are cash back cards better than points cards?
+
Neither is better in general. Cash back has a clear value. Points can be worth more or less depending on how you redeem them: American Express's Membership Rewards terms, for example, give a $10 travel credit for 1,000 points but charge 130 points per dollar for most gift cards. Compare the value you'd realistically get with what a cash back card would pay.
