Rocky, here's who I got. Born2bfree told you on Aug.10 2009 that Alberta had changed thier laws to match the rest of Canada. He gave you the official web site that said gas motors could no longer be put on bicycles in Alberta to match the rest of Canada.
That tells me that you can't put a gas motor on a bike in Canada legally.
You can also try the official gov. site Welcome Page | Page d'accueil
and look up motorized bicycles. They have photos of what is what. The only bicycle that looks like a bicycle as most people know them, can only be electric powered.
The company that I bought my hub motor from included the two official stickers in both official languages that it is a legal electric powered vehicle as required by law here in Canada.
