Rates and fees verified November 8, 2026.
One fact decides this whole guide, so here it is plainly: Costco warehouses in Canada accept Mastercard only (and debit). Visa and American Express do not work in-warehouse. Costco.ca takes more payment types, but at the warehouse door, your card needs to be a Mastercard — or you need to pay by debit.
This list starts with the cards we’ve fully verified; more are added as verification completes.

Best house card: CIBC Costco Mastercard
Annual fee: $0, with a Costco membership required. Earn: 2% at Costco.ca (first $8,000/yr) and 1% in-warehouse; 3% on restaurants and Costco gas, 2% on other gas and EV charging (gas tiers first $5,000/yr). Cash back is paid yearly as a Costco certificate. Extended warranty: +1 year. Foreign-transaction fee: 2.5%.
Be honest about the earn: in-warehouse earn is modest at 1%, and the 2% rate is for Costco.ca. This card earns its place through its 3% on restaurants and Costco gas, its $0 fee and its yearly Costco certificate — not through big in-warehouse rewards.
Best in-warehouse earner: Rogers Red World Elite Mastercard
Annual fee: $0. Earn: 2% on everything, including in-warehouse Costco purchases, with a Rogers, Fido or Shaw service (1.5% without). 3% on purchases in USD. Foreign-transaction fee: 2.5%. Extended warranty: +1 year. Income requirement: $80,000 personal / $150,000 household.
Note: Rogers terms change on November 18, 2026 — the Rogers-bill redemption bonus ends and some travel insurance is removed. Even so, this is the better in-warehouse earner in this list, at 2% on everything with a Rogers-family service.
Best for big-ticket Costco purchases: National Bank World Elite Mastercard
Annual fee: $150/yr. Earn: 1 pt/$1 at Costco. Extended warranty: triples the manufacturer’s warranty, up to +2 years. Foreign-transaction fee: 2.5%. Income requirement: $80,000 personal / $150,000 household.
Only 1 point per dollar at Costco — but its warranty triples the manufacturer’s warranty, up to +2 years. That is the play for big electronics and appliances bought at Costco, where an extra two years of warranty coverage can be worth far more than the points.
