Rogers Centre allows guests to bring food into the stadium as long as the items are wrapped, bagged or left inside a container to avoid spillage. Food containers must be soft-sided and small enough to fit under the guest's seat.

Bottles/Containers
Plastic bottles holding 600 ml or less will be permitted in Rogers Centre. This does not include liquor or beer. Outside alcohol is strictly prohibited from entering Rogers Centre. Plastic bottles holding more than 600 ml and glass bottles are prohibited.
if coming from home, my friend and his wife would usually bring a couple bottles of water to the game.
since i refuse to eat shitty stadium food (especially at their prices), i stopped off at banh mi boys for a sandwich before the game yesterday. I ate half on the way in case they won't let me bring it in and I'll have to toss it but i just threw the bag into the tray along with my keys and phone and i was in.
it was a pleasant surprise and i enjoyed the second half of my sandwich with a beer.
