Yes, whether you sign up on Amazon.CA or Amazon.COM you should still choose to sell on the U.S. Marketplace because it is significantly larger than the Canadian Marketplace meaning more buyers for your products. This in turn makes it much easier to grow and scale your business. 


I'm from Canada, which marketplace should I choose?


US or Candian marketplace?


Should we start off selling on multiple marketplaces like Canada and Mexico? Or just the US?
