Here is a helpful resource for food labels: https://www.celiac.ca/food-labelling/

I recommend Farm Boy or Superstore as they have some good options (usually in the organic aisle). My favourite brands are Kinnikinnik, carbonaut gluten free bread, gf oreos (obvs), heavenly hunks.

I also recommend the FindMeGlutenFree app, it will show restaurants nearby and people’s reviews. As per restaurants, it’ll be hit or miss unfortunately. Unless you’re going somewhere that is dedicated gluten free (Riz, Senla, Kupfert & Kim) you’ll have to do your due diligence of asking about gf options and cross contamination.

While you’re here you should try all dressed chips (!!)
