The person who took this “Ontario Giant Runt Club” photo – who goes by the online moniker “Bourbon Baby” (oddly enough, it’s not a pseudonym for bourbon aficionado David Crow) – did a little research and found that “giant runt” refers to a breed of pigeon; this is a pigeon fancier’s club in Toronto.
In case you were curious, this place is located at 615B Brock Avenue, just off Bloor Street West, halfway between Lansdowne and Dufferin. West End pigeon fanciers unite!
