The finding supplier lessons in the course are geared towards the US, but you can try to apply those same ones to the Canadian market and see if you get results. For example, with the online search method of searching for wholesalers, you can just throw in the word "Canada" to try to adapt it to the Canadian market to see if that helps. Then once you have a few suppliers, you can use the SpyFu method to try to multiply the number of Canadian suppliers that you've found. Additionally, you find Canadian suppliers using the directory of Canadian wholesalers in the link found here.
