We cross border grocery shop (day trip) almost every month bringing food back from Michigan to Ontario. Other than poultry (current restriction) we have never had an issue bringing any food back into Canada. The American rules are so complex and seem to change so frequently that we simply make sure we have no perishables in the fridge/freezer when we head south and whenever we are asked about food, I always tell them we are carrying no perishables at all, and we have not been checked yet (knock on wood). When we go south, we always factor in a grocery run on our first day into the US to stock up on the perishables, besides the fact that food is cheaper down south so there is little incentive to bring lots of food south with us.
