CIBC Costco Mastercard Review 2026
· By WalletFit Editorial Team
Is the CIBC Costco Mastercard worth having in your wallet? We break down the 3% restaurant rate, the 2% gas/Costco.ca multipliers, the 1% warehouse catch, and the 5% Executive Shop Card hack.
Despite being Costco's official co-branded credit card in Canada, in-warehouse purchases at physical Costco stores earn only 1% cash back. To get higher returns, Canadian shoppers must use online gift card hacks or pair their card with an Executive Membership.
CIBC Costco Mastercard Features & Spend Multipliers
| Spending Category | Cash Back Rate | Annual Category Cap | Post-Cap Rate |
|---|---|---|---|
| Restaurants & Dining | 3.0% | $5,000 / year | 1.0% |
| Costco Gas | 3.0% (2% at non-Costco gas) | $5,000 / year (combined gas) | 1.0% |

Key Benefits & Membership Integration
- No Credit Card Annual Fee: The card itself has a $0 annual fee, though you must maintain an active Canadian Costco Membership ($65 Gold Star or $130 Executive).
- Functions as Membership Card: Your Costco membership photo and barcode are printed on the back of the CIBC card, allowing it to double as your warehouse entry card.
- Mobile Pay Insurance & Purchase Protection: Includes extended warranty (doubles manufacturer warranty up to 1 year) and mobile device insurance up to $1,000 for lost, stolen, or damaged phones.
- Annual Redemption Coupon: Cash back is issued once per year in January as a digital Costco gift barcode, redeemable at any Canadian warehouse checkout.
The 5% Costco Optimization Hack
Because in-store warehouse spend yields only 1% cash back on the CIBC card, smart Canadian shoppers use a two-step optimization strategy:
- Upgrade to Costco Executive Membership (+2%): An Executive Membership costs an additional $65/year and earns a flat 2% reward on almost all in-store warehouse purchases (up to $1,250 annual max payout).
- Use a 2%–3% Flat Cashback Mastercard (+2% to +3%): Instead of paying with the CIBC card at the register, use the Rogers Mastercard (which gives 2% flat cash back, or 3% when redeemed against Rogers/Fido bills).
Executive Membership (2%) + Rogers Mastercard (3% bill credit return) = 5.0% Net Return on all Costco Purchases. Read our complete guide on Costco Canada Rewards Hacks → and compare all options in our Best Credit Cards for Costco Canada Showdown →
Verdict: Should You Apply?
The CIBC Costco Mastercard is an excellent no-fee secondary card if you frequently buy gas at Costco (3% cash back) or dine out (3% cash back). However, for in-warehouse grocery shopping, it should be paired with a higher-yielding flat Mastercard like the Rogers Mastercard or Scotia Momentum Visa Infinite (using Costco.ca online gift cards).
