This is definitely a Canadian recipe as I Personally recall seeing it on the side of the blue Catelli box, myself, as a child, on . It was the only pasta mom would buy, and a Canadian company since 1867. However, I could find no information about when the recipe first appeared on the side of the lasagna noodle box. The meat sauce and tomato sauce in this recipe are not the recipes on the side of the box. The idea and process is the same. The cottage cheese and spinach layer is key to the Traditional Canadian Lasagna, as is the mozzarella and the meat filling layers.
