Being in Canada I don't think you can even get exotics legally.

I know they have extremely strict import restrictions on a lot of insects, including roaches, millipedes, and stick insects. On another forum I belong to we have a lot of Canadian members who were interested in getting hissers after I shared photos and stories of mine, but best we can tell they are all illegal there.
It really is amazing that he survived the journey and you were there to take him in! I'm so sorry he's getting towards the end, but it sounds like he lived a very long happy life.
