The places I've been in Canada that do "Canadian cuisine" are usually based on regional ingredients. Things like PEI mussels, Alberta beef, wild Canadian salmon, wild halibut, caribou. Really "clean" food - with sides from Canadian-grown veggies or Canadian-made cheeses and fruit. And, good Canadian icewine!! For a "Canadian" food item coming down to the US, well, the candied salmon nuggets and salmon "Indian Candy" might fit the criteria.

Oh, for a Canadian restaurant, how about Earls's?? It's all over Western Canada, and there's at least 2 of them in Arizona (where the Canadians winter). It's Canadian, but definitely not Canadian cuisine!!
