Home Depot and Canadian Tire both carry 20 and 22 gauge brass wire. Works great for bunnies here in Alberta. Can't comment on regs in Ontario.
All I ever used was the 22 or 24 gauge brass wire. Snared hundreds of snowshoes when I was a kid, lost the odd one but not enough to get upset about.
Like red-eye said in post 27, tie your snare to something moveable. About a 1/2 inch diameter branch 3 feet long is just about right. Don't twist the wire too tightly when you attach the snare, as that will weaken the wire.
