Is there an annual fee for the BMO CashBack Mastercard?

No, the BMO CashBack Mastercard has no annual fee, making it one of the best free cash-back cards in Canada for grocery shoppers.

Combined with its 3% cash back on groceries, this card delivers strong value with zero ongoing cost as long as the account stays in good standing.

What is the welcome offer on the BMO CashBack Mastercard?

The current welcome offer for the BMO CashBack Mastercard is 5% cash back on all purchases for the first 3 months, capped at $2,000 in spending and $100 in welcome rewards. After the 3-month promo period, the regular earning rates apply: 3% on groceries (up to $500/month), 1% on recurring bill payments (up to $500/month), and 0.5% on everything else. The current offer expires June 30, 2026, so apply soon to secure the welcome bonus.

How much cash back can I earn on groceries each year?

The BMO CashBack Mastercard pays 3% cash back on grocery purchases up to $500 per month, which works out to a maximum of $180 per year on groceries alone ($500 x 12 months x 3%). Above the $500 monthly cap, grocery spending earns the base 0.5% rate. For households spending more than $500/month on groceries, pairing this card with the BMO CashBack World Elite Mastercard (5% on $500 of monthly groceries) can stack the savings.

Is the BMO CashBack Mastercard accepted at Costco?

Yes, the BMO CashBack Mastercard is accepted at Costco Canada because Costco's exclusive credit card network is Mastercard. However, Costco purchases earn the base 0.5% cash-back rate, not the 3% grocery rate (since Costco classifies as a wholesale club, not a grocery store). For higher Costco rewards, consider pairing this card with the BMO CashBack World Elite Mastercard or stacking with another points-earning Mastercard like the National Bank World Elite, which earns 5 points per dollar in the grocery category.
