When I lived in England, there was a little Canadian shop near Covent Garden Market. In it I found, of all things, Kraft Dinner.
I live in the USA now & my husband laughs when I still call mac & cheese Kraft Dinner. lol.
The shop also had Shreddies cereal, Smarties (like m&ms) and a brand of root beer you can only get in Canada (I forget the name).
Other Canadian products? Tim Horton's coffee, Canadian bacon and maple syrup. We do have lumberjack roots!
I once ordered a Caesar in a US restaurant and was brought a salad. I really wanted a Clamato and vodka drink (like a bloody Mary, but with Clamato juice). I had not idea it was a Canadian thing.
These examples are not really fine cuisine, but they are interesting aspects of Canadian food pop culture.
