Spousal sponsorship

[YVR123]

I applied for PR under family class within Canada and I am currently in Canada as a visitor.
My status expires in January and I haven't received an AOR yet. Do you apply for a visitor extension or is there any other way?
I know that I can apply for an open work permit as soon as I received the AOR, but how can I make sure that I am not overstay my visa?

if you want to stay on the safe side, apply to extend your stay as a visitor before you status expires.
