Go into the washroom and eat/drink on the toiletHere’s the wording from the updated health order:
It definitely sounds like the concessions at TD Place will not be able to open. Which is fine for a 2 hour concert, or 3 hour hockey game, but as @luckiest1 has pointed out, not reasonable when you’re spending 12 hours in the arena. Allowing spectators to bring in snacks and beverages might be an option, although where they could be consumed could be an issue since I imagine the point of the restriction is to ensure everyone keeps their masks on at all times while indoors. Maybe add the requirement that you have to go outside to eat/drink?
