IMO, English Canadians don’t really have a food that they can call their own. Quebec has poutine, tourtieres, pea soup, and other things. English Canada eats many of those things, but also a lot of generic North American or European things: hamburgers, steaks, North-American style pizza, pasta, stew, etc.

Where I think Canada might be a bit different is that after decades of high levels of immigration, Canada has a lot of foods from other parts of the world. It’s common to find South Indian, Pakistani, Punjabi, Turkish, Persian, Carribean, Chinese, Japanese, Vietnamese, Thai, Korean, Mexican, etc. restaurants in a city. Many of them cater to immigrants from those countries, so they’re authentic tasting.

A lot of that is made at home too. While a home-made stir fry probably wouldn’t taste authentically Chinese to someone from China, there are many meals from around the world that have been adapted for Canadian tastes. Very white people in Canada often cook adapted versions of Indian curries, Chinese stir fries, Mexican tacos, Thai curries, etc.
