Costco top grocery retailer in Canada
December 12, 2025
Costco ranks as Canada's top grocery retailer for the second consecutive year, according to a dunnhumby's Retail Preference Index for Canada.
The nationwide brand equity study examines the $115 billion Canadian grocery market by analyzing customer and financial data for the 28 largest conventional, discount, superstore, and club banners in Canada, which represent 97% of market share, according to a press release.
Maxi, Food Basics and Real Canadian Superstore followed Costco as the top four grocery retailers. No Frills, Super C, Walmart, Fresh Co., and Dominion round out the top nine.
"Even though inflation and interest rates have dropped, Canadians still face affordability issues and are focused on value and savings more than last year," Matt O'Grady, dunnhumby's president of the Americas, said in the release.
