Cheapest Grocery Store in Mississauga 2026: Real Price Data
We tracked prices across 19 grocery chains in Mississauga to find out where your dollar goes furthest. As of July 20, 2026, no single chain wins across the board — the cheapest place to shop depends on what is in your cart. Below are the sharpest same-package price gaps we found.
Big Price Gaps on Common Items
Even when we hold the package size constant, the same product can vary dramatically across chains. Shredded Cheese shows the widest verified gap we found on an identical pack: a 453g bag runs $7.49 (sale) at Marché Adonis but $15.99 (sale) at Sobeys — 113% more for the same bag.
Pantry staples show the same pattern. Primo Pasta Sauce costs just $0.97 (sale, regular $1.27) at Giant compared to $2.49 (sale) at Metro — 157% more. General Mills cereal is $3.49 (sale) at Metro versus $8.99 (sale) at Sobeys (package sizes not specified in source, so treat this as a general range rather than an identical-pack comparison).
Snacks and Dairy Comparisons
If you are stocking up on snacks or dairy, checking multiple flyers is essential. We found significant savings on chips and yogurt depending on where you shop.

Bottom Line
No single Mississauga chain wins across the board — Metro, Walmart, and No Frills each take the top spot on multiple items in our tracked set, and value shifts week to week. Nearly every low price in this report is a temporary sale: the $0.97 Primo Pasta Sauce at Giant and the $0.99/lb ($2.18/kg) tomatoes at Real Canadian Superstore are promotional rates that will change.
