Family of 4. Spend $1,500/month at Costco. Get $540/year cash back. Plus 4% on gas = another $150. Card + Cobalt = perfect wallet.
Overview
The CIBC Costco Mastercard exists because of Costco's exclusive network agreement: Costco Canada accepts only Mastercard, and CIBC is the issuer partner. If you want to pay for warehouse purchases or Costco gas with a credit card, this is your only option.
Earn 3% on Costco (warehouse + Costco.ca + Costco gas bars), 4% on gas at any station, 2% at restaurants + bars, 1% on everything else. Cash back deposits annually as a Costco rebate cheque (mailed to your address each January).
No annual fee. Must have valid Costco membership ($65/year Gold Star or $135 Executive). For families spending $500+/month at Costco, the rewards alone exceed the membership fee — making the card + membership combo effectively free.
Welcome bonus

Editor's verdict
Essential for Costco loyalists. Useless without membership.
The math is binary. If you're a Costco member spending $500+/month, this card delivers $200+/year in cash back at $0 fee — easily covering the membership fee. If you don't shop Costco, the card has limited value. Best paired with Amex Cobalt (for groceries/dining outside Costco) for full coverage.

Essential for Costco. Wish cash back was monthly instead of January. Also wish FX-free.
