I wish I had seen this post earlier. It was pointed out to me today.
In Canada, an Ebike requires a sticker by the final manufacturer of the Ebike. If you are building your own Ebike you can put your own sticker on it as you are the final manufacturer. If you are buying a complete Ebike the retailer must provide a sticker stating its a legal Ebike.
The officer that seemed so knowledgeable about Ebike laws needs to do some research before scaring people with his comments. I am a founding member of TERA which is an organization formed to make Ebike laws fair in Toronto. TERA is a huge reason Ebikes have the rights they do in the City of Toronto. We went through a lot to get the Ebike laws flipped in our favor. Including a forced vote in City hall. I know of no instance in Canada of anyone having an issue with building an Ebike and running it at 500w 32kl/h. I have even been to public hearings on Ebikes where police officers looked at all our Ebikes. Some of them loved Ebikes. Others hate them, and no such comments were ever made.
There are thousands of homemade Ebikes in Canada. More every year. Homemade Ebikes were on the roads in Canada long before the prebuilt Ebikes of today showed up. I would be very surprised if you could find one documented instance, where a person was actually fined for having a homemade Ebike and no sticker on it.
