I am not concerned about mail forwarding, I am concerned about the lease I signed, my lease begins on July 1st 2022 until that I need to get the work permit extension approval, If I dont get it then I wont be able to move outside the province (which will be a loss for me financially)you can change address on IRCC. However there is no guarantee that it will be sent to the new address.
It's best that you get it before you move, but there is very limited things that you can do.
You can also set up mail forwarding with Canada Post.
