At the risk of solidifying my old age. I was born and raised very close to Quebec. Many of my family were French Canadian, not to be confused with my wife who was English Canadian and therefore could not find any food bland enough to fill her desires. Anyway, we always had ketchup on our pan fried or scrambled eggs. Never knew any other way. I still have eggs daily and use ketchup every time. When I moved south I confined it to just when at home or I would order home fries that for some reason was acceptable to put ketchup on and I'd use enough to share it discretely with my eggs.
There was also something that my mother and father growing up during the depression added to the menu. It was a bread, butter and ketchup sandwich. It was my favorite a young child mostly because my dad ate them all the time. A couple other things he liked that my 1950's brain could not adjust to were things like "Blood Pudding", Head Cheese and eating sardines right out of the can. Even a kid who wanted to be like his dad, had his limitations.
