Costco runs on the same basic membership model in Canada and the United States, but the details are not identical. From annual fees to reward terms and online shopping rules, these differences can affect which plan makes sense and how much value members actually get.
Annual membership fees
The first difference shows up before you even enter the warehouse. In the United States, Costco says a Gold Star membership costs $65 a year, while an Executive membership costs $130. In Canada, Costco lists Gold Star at C$65 and Executive at C$130.
That sounds almost identical, but the currencies matter. A Canadian member pays in Canadian dollars, while a US member pays in US dollars, so the real cost changes with exchange rates. Business memberships are also priced differently by currency, with Costco Canada listing Business at C$65 and Costco US listing Business at $65.
Executive 2% reward limits
The Executive tier includes an annual 2% reward in both countries, but the fine print is different where the cap is concerned. Costco US says Executive members can earn up to $1,250 on qualified purchases each year. Costco Canada states that the maximum annual 2% Reward is C$1,250.
The percentage is the same, but the payout is not equal once currency is considered. That means a heavy spender in the US and a heavy spender in Canada do not reach exactly the same value ceiling in practical terms. In both countries, taxes, delivery fees, and several excluded categories do not count toward the reward.
Mastercard in Canada, Visa in the US
Payment is one of the clearest differences members notice at checkout. In Costco warehouses in the United States, Costco accepts all Visa cards, cash, checks, debit and certain digital payments, according to Costco US. In Canada, Costco warehouses accept Mastercard, debit cards, cash, and Costco Shop Cards, according to Costco Canada.
That means a US member with a favorite Mastercard may need a different card for warehouse purchases, while a Canadian member faces the opposite issue with Visa credit cards in store. The co-branded cards are different too. Costco partners with CIBC Mastercard in Canada and with Citi Visa in the United States.
Online shopping access and shipping terms
Membership helps unlock online shopping in both countries, but each national site has its own rules and inventory. Costco.ca serves Canadian shoppers, while Costco.com serves US shoppers, and product selection, pricing, promotions, and delivery availability are not the same across those sites.
Costco Canada also notes that some items on Costco.ca include shipping and handling in the displayed price, while pricing structures can differ on Costco.com. Even when the same brand appears on both sites, package sizes, item numbers, and shipping restrictions can vary. For members who shop online often, that can be just as important as the annual fee.
Pharmacy and prescription differences
The last major difference comes from national health and pharmacy rules rather than the membership card itself. Costco operates pharmacies in both countries, but prescription processes, drug coverage, and regulations differ because Canada and the US have separate healthcare systems and provincial or state rules.
In both countries, you do not need to be a Costco member to use the pharmacy, because Costco notes that pharmacy access is available to nonmembers where required by law. Still, the experience can differ in practical ways, including insurance coordination, drug pricing, and eligible services. For many households, that makes the pharmacy one of the most meaningful cross-border differences.
