Being from Quebec (The french part of Canada), I will have to go with poutine. However, its not your ordinary french fries, gravy and cheese curds but a fusion of vietnamese cuisine and Quebec's most iconic dish. *Yes I know that ramen are from japan but the restaurant that makes the spicy ramen poutine is mainly vietnamese.
See the picture + description of the dish:
Fries, cheese curds, spicy ramen cheddar sauce "Spicy Ramen Challenge", kimchi, house sweet and sour sauce. The sauce contains gluten, sesame and fish. It cannot be made less spicy and may not be suitable for children.
