I don't see why you would need to register in each province when you are selling online to the other provinces, you are not going to do a sale in that province. I know when I used to travel to do sales in other provinces sometimes the city would require me to get a visitor license to sell there and I also had to collect taxes and submit them for the province where I was selling. Not sure about Saskatchewan...I live here...I have a business license for Saskatoon, but I am not sure why you would have to submit your name. was there a fee? I know that anything I purchase from out of the province I am supposed to voluntarily pay pst on.
You might try calling Saskatchewan a second time if you are concerned. I find sometimes I get different answers depending on who answers the phone that day.
