Chapter 400-14 of the Municipal Code of the former City of Toronto (which is still in effect, as far as I can tell) states:
C. No person shall throw any stone or ball of snow or ice, parcel, bundle or other dangerous missile or use any bow and arrow or catapult in any highway.
No bows and arrows or catapults on the streets? There go those meddlesome bureaucrats again, interfering with innocent medieval childhood fun. Next thing you know, they’ll be regulating flails and quarterstaffs.
