Since they are holding our files on the final decision for PR as our dependent are in outland on the name of COVID, can we apply for Visitor or work permit for the spouse so they can come here?
Yes. That's what most people are doing...
Although it's not guarantee that once your spouse is in Canada and you update their address to the same is yours (in order to show that they're in Canada now with you), they'll process and finalize your PR application faster...
There are people that already have done this, and after 3, 4 months of updating the address, they are still waiting for final approval...
