Sadly it's just not the same as the US locations. In the US you can readily order a vegetarian sub which consists of cheese (3 different varieties) and mushrooms and your choice of standard toppings. Despite contacting customer service and being assured that this is an option in Canada as well, none of the locations seem to know about it or offer it as an option.
Unfortunately the only veggie option seems to be the Mediterranean which honestly is subpar.
Customer service has said it's an "underground menu" item and that the locations should be aware of it. However when I ask I'm always met with a deer in the headlights type reaction.
The bread and quality of toppings is great but unfortunately the menu just doesn't match up to that of the US locations.
