You can keep pigeons in Ottawa. My brother -in-law does legally. Now you may not want a coop outside, but I trained successfully with 6-8 a week in a dog crate in the garage. You must use them up every week. Small animal auctions sell them for around 2$ a bird. It's a bit of a pain but you only need them for maybe 8 + weeks and you can switch to small quail, depending on the dog's progress.
