Hello Zakmalik, I will try to answer your question but my info. may not be up to date so please keep that in mind. You could sponsor your husband outland while he is living here but as far as I know he does have to be "in status". That is the part you may need some more advice on. He could leave Canada and return but that is a risk as he may be refused entry on his way back into Canada due to his expired visa. If you do not get any other definitive answers here on the forum then you could contact an immigration lawyer for advice. Many of them will do a free consultation or it may be worth it to pay for 30-60 minutes of their time so that they could guide you as the best steps to take.
There are also some senior members on this forum that you could send a personal message (PM) to and that may be a more effective way of getting an answer. The people that come to mind off the top of my head are - PMM, Leon and Scylla. You can search for them by their member name. Hope this helps a bit. Blessings.
p.s. not sure how many posts you need in order to send a PM but if you do not have enough then re-post your first message with a different topic name like - "Seniors Pls. Help - PMM, Leon, Scylla" or something like that to flag them.
