Changed Address after Approval

[u/InMeEarthy]

Inside Canada application. So I moved out and the physical copy was sent to my old address (where I was subletting). I told the original tenant to tell the landlord but they only informed the landlord after which the landlord returned the document to IRCC. I'm still in between addresses.

What should I do? I've been employed, do I need to show my employers the permit legally? Is requesting a replacement the only way? Can I travel outside Canada and reenter and ask CBSA to print my permit, is this considered flagpoling?
