We checked every item against our Canada-wide Costco price history — prices and past sale dates are on the cards below.

💳 Costco Executive & Gold Star Memberships in Canada
Compare plans or sign up online through the official Costco membership portal anytime.
If you shop at Costco often, upgrading to an Executive Membership (CA $130 / year) can be a smart move. It includes all the benefits of the regular Gold Star Membership (CA $65 / year) plus 2% annual rewards on most eligible purchases.
Is the Executive Membership worth it? If you usually spend around CA $542 or more per month at Costco (about CA $6,500 per year), your 2% cashback will essentially cover the membership cost. Everything you earn beyond that is pure savings.
For lighter shoppers, the Gold Star Membership remains a great value — it gives you full access to all Costco Canada warehouses and online deals.
Both memberships are fully refundable if you're not satisfied, so you can upgrade or downgrade anytime with confidence.
