Your local Thornhill Subway® Restaurant at 300 John Street brings bold new flavors and classic favorites to guests every day. Enjoy our famous Footlongs, 6" sandwiches, wraps, and salads, ordered quickly in the app or online, through convenient delivery, in-restaurant dining, or curbside pickup. We’re proud to offer a fresh alternative to typical fast food with fresh-cut veggies, tasty proteins, fresh-baked bread, and delicious cookies. We’re also here for your catering needs.

I love coming here after my workouts because I can get a fresh protein-filled sandwich without feeling guilty. The ingredients taste clean and the bread is always soft. The staff are also super helpful especially when you’re trying to decide between sauces. Definitely recommend the Steak & Cheese with Chipotle sauce.

DO NOT BUY FROM HERE!!! Horrible and dirty. The staff are extremely rude and they always hide at the back, so if you wanna order you can't because there is no one at the register. They don't care about customers or the food they serve. I'd rather die of hunger than to come back to this place again.
