Me and my family did soft landing in June 2021. In July 2022, we moved to Canada permanently.
At the time of landing didn't apply for PR card or SIN.
I have applied for the PR card (online portal) few weeks ago. I can't get SIN since COPR is older than 1 year.
My employer want to transfer me to Canada but for that SIN is needed.
Q1. How long can I continue to work remotely in Canada and getting US payroll ( I have US green card and Re-entry permit applied)?
You'd just be working for a foreign employer while a permanent resident residing in Canada, which is allowed, you just have to declare that income and pay taxes.
