The purpose of Ontario's hunter orange regulation is to maximize hunter safety by making hunters highly visible to each other while maintaining low visibility to colorblind big game such as Moose and Whitetail Deer.
Under this regulation, all licensed hunters, including archery hunters hunting during rifle season for deer and moose, are required to wear hunter orange. Black Bear hunters are required to wear hunter orange while traveling to and from tree stands but because Black Bears see color; bear hunters are exempt from wearing hunter orange while in the tree stand.
Waterfowl hunters and archery hunters in archery-only areas are exempt from the hunter orange requirement.
A hunter orange garment and head cover must be worn. The hunter orange garment must cover a minimum of 400 square inches above the waist and be visible from all sides. Open mesh or camouflage hunter orange does not quality in Ontario. It has to be solid hunter orange. A hunting coat or vest generally meets this requirement. The hunter orange hat needs to be worn and cannot contain camouflage material.
