All 104 of the 104 regular warehouses in Costco's store data keep exactly these hours, from St. John's to Victoria. Costco's 11 Business Centres keep the longer Business Centre hours. Unlike in the U.S., Canadian warehouses open at the same time on weekends as on weekdays.

Gas station and pharmacy hours

Gas stations open earlier and close later than the warehouse. At the Calgary warehouse we checked on Costco.ca, gas ran from 6 a.m. to 9:30 p.m. on weekdays and 6 a.m. to 8:30 p.m. on weekends, and the pharmacy kept the same hours as the warehouse. Gas and pharmacy hours are set by each location, so check your warehouse's page.

Holiday hours

Costco closes on most statutory holidays, but the rules differ by province: Quebec warehouses stay open on Family Day, Victoria Day and Thanksgiving, for example, and Quebec, Alberta and B.C. are open on Good Friday. See Costco holiday closures in Canada for every date.
