"Antlers or horns are accepted as checked baggage only"

I flew with Air Canada today, and was surprised when their check-in terminal asked was I carrying any antlers or horns.

It turns out that Air Canada has all sorts of regulations for transporting antlers, horns, "bounty", and guns.

I note that "Latitude and Executive fare customers are entitled to check their antlers or horns (one piece per passenger) at no charge for travel within Canada and the 50 United States."

I guess that Air Canada Latitude and Executive fare passengers must really stand out from the crowd in an airport (unless they have checked their antlers or horns, that is).
