Is a Costco Membership Worth It in Canada?

Costco offers two membership tiers in Canada: Gold Star at $65 per year and Executive at $130 per year. The Executive membership gets you 2% cashback on all Costco purchases, capping at $1,000 back per year. That means you need to spend at least $6,500 per year at Costco for the Executive upgrade to pay for itself — which works out to about $540 per month.

Gas savings alone can cover a significant portion of the membership fee. Costco gas is typically $0.05 to $0.10 per litre cheaper than surrounding stations. If you fill up once a week with a 50-litre tank, that is $130 to $260 in annual gas savings. For many families, the gas discount alone justifies the Gold Star membership.

Kirkland Signature, Costco's house brand, is genuinely excellent quality at lower prices. From olive oil to laundry detergent to diapers, Kirkland products consistently match or beat name brands in blind tests. Bulk buying on staples like toilet paper, paper towels, and cleaning supplies offers real per-unit savings — but only if you actually use everything before it expires.

The biggest risk is impulse buying. Costco's treasure-hunt layout is designed to make you spend more than you planned. Going in for milk and leaving with a $300 patio set is a real phenomenon. Singles or couples in small apartments may also struggle with bulk sizes — a 4-kilogram bag of rice is not helpful if it goes stale before you finish it.

Costco's optical department, pharmacy, and tire centre offer additional savings that many members overlook. Prescription prices are often the lowest in town, and their optical lab produces quality glasses at a fraction of boutique prices.
