FCC does not certify terminal equipment (i.e. telephone sets etc.) in Canada, they only look after the US market.

To be sold in Canada these devices require an Industry Canada listing to prove that they meet the following requirements.

I have been told that Sears in Canada wont service their branded electronics that people bought in the US and brought over the border as the requirements differ.
