Gas and food sales margins rising twice as fast as retail average

Rapidly increasing retail sales margins on food and fuel inflation and supercharging inflation

The sales margin at gas stations and grocery stores is increasing twice as fast as among businesses in all retail sectors, according to data released last Thursday.

And that hike in margins is paying off handsomely for Loblaw investors, according to the company’s most recent financial report.

Food and gas sales margin up 2x faster than all retail

The retail service price index (RSPI) measures changes to the cost of “retail service,” the costs added to retail goods by retail service providers. The retail service price “is defined as the margin earned on the sale of a good,” according to Statistics Canada. It’s the difference between the wholesale price paid by the retailer and the final price charged to the consumer.

Across all retail businesses, the RSPI is up by 21.8 per cent, which tracks closely to the rate of inflation. But for gas stores, the index is up nearly 43 per cent — or twice as fast — while for grocery stores the RSPI is up nearly 56 per cent — about 2.5 times the pace of the whole retail sector.

In January 2020, the sector-wide RSPI was at 108. In the grocery sector the index was 102 and at 111 for gas stations. In April 2026, the RSPI had climbed to 131. But the sales margin index for gas stations and grocery stores had climbed to 158.

Statistics Canada provides data for grocery stores as an aggregate. It does not provide a more detailed break-down in the acceleration of sales margins showing values for supermarkets and smaller stores. Sales margins at the big supermarket chains may be growing even faster than for the grocery sector.

The cost of retail services does includes labour, rents, etc. born by the retailer as well as shareholder returns. But operational costs like wage and rent have certainly not increased two or more times faster than inflation.
