@Freya, not sure about Canadian "breakfasts." Perhaps slices of peameal bacon aka "Canadian bacon"? I have definitely heard of Canadian treats called "butter tarts" and "Nanaimo Bars". Also, French Canadian meat pies called Tourtieres - minced beef and pork, maybe some onions (other veggies depending on chef, but then it might not be traditional if you change the original recipe) in pastry shell. Very rich and fatty. Poutine has been mentioned. There is also maple syrup taffy - best done in deep winter - boil down some maple syrup until it's super thick and gooey, then drizzle it on a pan of fresh clean snow to make pieces of taffy. (Hard on the teeth, but tastes very good!) For lunch or appetizers, Newfoundland might offer cod tongues: "Fried cod tongues are a traditional Newfoundland food, often served as an appetizer. They are actually a little muscle from the neck of the fish. In terms of texture and flavour, they are somewhere between a cod fillet and a whole belly clam."
Good luck. If I have my druthers, I like sweets and have made tourtiere myself. I'd pass on the cod tongues, but would have some salmon that
@Rockclimbinggirl offers.
Butter tarts: pastry shells filled with mixture of melted butter, corn syrup (or maple syrup), drop of lemon juice, nutmeg, egg, and brown sugar - baked.
Nanaimo bars: layers of wafer crumbs with chocolate, coconut, sugar, butter; vanilla custard butter cream icing; chocolate top (put in fridge, not baked):
