I do not believe it is legal in Ontario to free range turkeys. Although, <shrug>, you know
I've had the big broadbreasted ones loose in a reasonably-well-fenced horse pasture. They couldn't meaningfully fly by that point so they were kinda stuck there and had a good attitude about it. "Real" turkeys would not stay put so well though.
My intention/hope is to try free-ranging some of mine (which by now are real rather than BB) next year, out of the horse barn... but I don't know how well it will work. People say they go all over the place.
