dunnhumby, a global leader in customer data science, has named Costco as Canada’s top grocery retailer for the second consecutive year in the dunnhumby Retailer Preference Index (RPI) for Canada.

The top nine grocers in the RPI, almost entirely club, discount, and superstore formats, lead in saving Canadians money (price, promotions, and rewards)— the most important pillar for Canadian consumers in the RPI. This pillar drives 44% of financial and customer results. Retailers who have a competitive advantage in this pillar are more likely to achieve long-term success.
“Even though inflation and interest rates have dropped, Canadians still face affordability issues and are focused on value and savings more than last year,” said Matt O’Grady, dunnhumby’s President of the Americas. “This RPI report gives retailers important data and insights to adjust their customer strategies and offerings to better help their customers meet their needs.”
