Hi Daniel and welcome to the forum
Don't worry, dropshipping is the same as you were doing before, When suppliers ask for tax ids and so on, they are wholesalers. So unless you are buying in bulk, then things like that won't effect you at all. Just use the menu options in our directory to filter out all other suppliers such as wholesalers, just search for dropshippers and you won't find those types of supplier requirements.
Btw, being in Canada doesn't present any problems with dropshipping either, so all good :)
