I am a US citizen currently living in Canada and going through the Permanent Residency process. I was recently approved for a work permit. While I've been here, to keep busy and to maintain an income, I have been working as an independent contractor for a company in the US. I have been paying US federal taxes every quarter, but I am curious if now that I have a work permit, do I also need to pay taxes to Canada? Or does that happen when I receive my PR status? Thank you.
