I could say sushi (ate more of it in my life than all of you together) but then I could say the food that my mum makes.
When I was small I made 'friends' who were visiting me just to eat my mums food... ;/

As a fellow Canadian I lol'd pretty had at Jordahan's post. But my favorite food would probably have to be an old fashioned grill cheese, add bacon to that and it's even better!
