Loblaws branded stores disappeared from QC years ago. In Québec, Métro is pretty expensive, like IGA or Provigo. The cheapest groceries are Maxi (yeah, it’s Loblaws group) and SuperC (Metro group). But for me, all fruits/vegetable comes from local greengrocers, who also sell various ham/cold cuts and lot of cheese, sometimes for 50% of the price of groceries, and it’s fresh cut. Else for some bulks there’s bulk barn, and Costco, or sometimes even Amazon, a family box size cereal is $10.99 at IGA and the same one is $5.49 on Amazon.
I know, Maxi is part of Loblaws as I wrote, but unfortunately it is the cheapest grocery in QC, but I go more and more at SuperC now.
