I found a list of the “Gluten Friendly” options posted in the Toronto Maple Leafs app - see photo below!
Found gluten free beer Glutenberg blonde by concession 323 gate. Had a burger at Poutiniere with a GF bun. No problems after.
— Somewhat
— Some
— Excellent
In the Box/Suites they are great with celiac and knowledgeable. Online the menu for ordering has items marked also. The celiac safe food was on a separate table and the staff made sure I took first. Had spring rolls, chicken and beef skewers, wings. The popcorn was also safe.
— Very
— Gluten-free items are marked on the main menu

— Good
Small selection of gluten free snacks at concession stands. They do have a Freshii with a few gluten free options. I would not recommend eating meals here.
