That's a very good question.
When you look at certain places in the city of Vancouver, they've introduced accessibility aspects by just requiring businesses to have those items on hand if a customer asks for them and is clearly in need of the item for an accessibility reason. They are not to just leave them available for every other customer. That's the approach they've taken in Vancouver.
I wouldn't necessarily be able to give you more ideas of what this would look like. I think Vancouver right now is the only jurisdiction that has introduced those requirements.
