Yes, it is bizarre. I am really surprised to learn that Canada has “blue laws”, at all.
Remember when the US, also, had Blue Laws? Closed on Sunday.
I went to college in Massachusetts before they starting getting rid of all of the blue laws.
My favorite, which may still be on the books, is that it was illegal to advertise that you were serving alcohol at a party.
So the code language for having alcohol at an event or party was always “traditional refreshments will be served.”
