"What credit cards does Costco Canada accept?"

"Costco Canada accepts Mastercard credit and debit cards only. Visa credit cards, American Express, and Visa Debit are not accepted at any Costco warehouse or at Costco.ca. This applies to all Costco locations across Canada. Costco also accepts cash, cheque, and debit (Interac). If you only have a Visa or Amex credit card, you will not be able to use it at Costco — you will need a Mastercard (or debit/cash)."

"Why does Costco Canada only accept Mastercard?"

"Costco Canada has an exclusive payment processing agreement with Mastercard. Costco negotiates low merchant processing fees in exchange for exclusivity — a business model consistent with Costco's low-margin, high-volume approach. The agreement means Costco does not pay Visa's or Amex's typically higher interchange fees. The Costco-Mastercard-only agreement is specific to Canada — Costco US accepts Visa, and Costco UK accepts Visa."

"Which Mastercard earns the most rewards at Costco Canada?"

"The best Mastercard for Costco Canada depends on your other spending. Top options: (1) CIBC Costco Mastercard — earns 3% cash back on Costco.ca and restaurant spending, 2% on Costco gas; purpose-built for Costco members. (2) Rogers Red World Elite Mastercard — earns 1.5% everywhere (including Costco); best for US spending too. (3) BMO CashBack World Elite Mastercard — earns 5% on grocery (Costco earns 1% as it's coded as a warehouse club, not grocery). (4) Tangerine Money-Back — 2% in chosen categories (grocery, gas, etc.); Costco may or may not qualify as grocery, depending on Mastercard coding. Check with Tangerine."

"Does the CIBC Costco Mastercard earn rewards at Costco?"

"Yes — the CIBC Costco Mastercard is purpose-built for Costco members and earns: 3% cash back at restaurants worldwide and on Costco.ca; 2% cash back at Costco gas bars; 1% everywhere else including in-warehouse Costco purchases (food court, pharmacy, and general merchandise). Cash back is issued annually as a Costco cash coupon redeemable in-warehouse. There is no annual credit card fee (though Costco membership is required)."

"Can I use my Visa at Costco Canada?"

"No — Visa credit cards are not accepted at Costco Canada warehouses or at Costco.ca. This includes all Visa cards: Visa Infinite, Visa Platinum, Visa Classic, and Visa Debit. If you arrive at Costco with only a Visa card, your only options are to pay with: a Mastercard (credit or debit), Interac debit, cash, or cheque. Consider applying for a no-fee Mastercard (Rogers Red, Tangerine, or CIBC Costco) to use at Costco alongside your Visa."

What Credit Card Does Costco Take in Canada? (2026)

Costco Canada accepts Mastercard only — no Visa, no Amex, no Visa Debit. This is one of the most common questions from new Costco members in Canada and it catches many shoppers off-guard.

Here’s everything you need to know: what’s accepted, why, and which Mastercard earns the most rewards at Costco.

What Costco Canada Accepts

Payment Method	Accepted at Costco Canada?
Mastercard (credit)	✓ Yes
Mastercard (debit)	✓ Yes
Interac Debit	✓ Yes
Cash	✓ Yes
Personal cheque	✓ Yes
Visa (credit)	No
Visa Debit	No
American Express	No
Discover	No

This applies to all Costco warehouse locations in Canada and to Costco.ca online shopping. In-store and online: Mastercard or debit/cash only.

Why Only Mastercard?

Costco operates on an exclusive agreement with Mastercard Canada (currently processed through CIBC Mastercard infrastructure). Costco’s business model is built on thin margins and high volume — accepting cards with lower interchange fees allows Costco to keep prices lower for members.

This is a Canada-specific arrangement:

Costco Canada: Mastercard only
Costco USA: Visa only (Citi Visa exclusive)
Costco UK/Australia: Visa accepted

If you frequently cross-border shop at Costco US, note that your Canadian Mastercard will work there (most Mastercards are accepted in the US), but Costco US’s own co-branded card is a Visa.

Best Mastercards for Costco Canada

1. CIBC Costco Mastercard — Best for Costco Members

Annual fee: $0 (Costco membership required, ~$65–$130/year)
Earn rates:

3% cash back at restaurants worldwide and on Costco.ca
2% cash back at Costco gas bars
1% cash back at Costco in-warehouse and everywhere else

Cash back is paid annually as a Costco Cash coupon redeemable in-warehouse.

This is the purpose-built Costco card in Canada — if you are a Costco member and spend heavily at Costco gas and Costco.ca, the CIBC Costco Mastercard earns more at those specific Costco touchpoints than any other card.

Limitation: Cash back is only usable at Costco (as a Costco Cash coupon), not as a general statement credit.

2. Rogers Red World Elite Mastercard — Best Flat-Rate

Annual fee: $0 (income requirement: $80K personal)
Earn rates:

1.5% cash back on all purchases everywhere — including Costco in-warehouse
3% cash back on foreign currency purchases (net +0.5% after 2.5% FX fee)

Rogers Red earns 1.5% on all Costco purchases — better than CIBC Costco’s 1% in-warehouse (though worse than CIBC’s 2% at Costco gas bars and 3% at restaurants). Cash back is a monthly statement credit, usable anywhere.

Best if you want simple flat-rate cash back that works at Costco and everywhere else.

3. BMO CashBack World Elite Mastercard — Best for Non-Costco Grocery

Annual fee: $120 (income requirement: $80K personal)
Earn rates:

5% cash back at grocery stores (up to $500/month)
4% on transit and recurring bills
2% on gas and streaming
1% everywhere else — including Costco

Important: Costco is typically coded as a warehouse club or wholesale, not as a grocery store. This means Costco purchases usually earn 1% (base rate), not 5% grocery bonus. Verify the Costco merchant category code with BMO before relying on grocery category earn.

Best if most of your grocery spend is at regular supermarkets — you get 5% at Sobeys, Loblaws, Metro, etc., and 1% at Costco.

4. Tangerine Money-Back Credit Card — Best Budget Option

Annual fee: $0 (income requirement: $12K)
Earn rates:

2% in 2 chosen categories (grocery, gas, dining, etc.)
0.5% everywhere else

Costco note: Whether Costco qualifies as the “grocery” category with Tangerine depends on how Mastercard codes the merchant. Some users report Costco coding as grocery; others report warehouse/wholesale. Contact Tangerine to confirm before counting on 2% at Costco.

Best for budget-conscious shoppers who want a no-fee Mastercard with some category earn.
