Sorry DarR, but the bike is only compliant if it is "as delivered" regardless of the country. In Canada, that means the same as the US, so you will see the EPA compliance sticker somewhere on the bike, even though it means nothing to us.
Most, if not all, of the dealers in this area will not give you a safety compliance certificate if the cat is missing or if there are other obvious signs of modification. The OEMs are very careful with this, they don't want or need the Government adding more regulations to the industry. Others may not be as discerning in their inspection.
If you'd like to investigate importation, check the RIV government site, there's a list of allowable vehicles. And if you decide to pick the bike up at the factory and bring it to Canada, they will make sure you have a Canadian (North America) bike so that you won't get stopped at import.
