Thank you for your answer.It's fine. You'd update via a webform (or email if you have warsaw email contact) your change of address. Should not slow down the app, in fact, possibly help as you'll have shown you are going back to Canada (the 'intent to return' part).
You can also apply for a TRV for him. It may or may not be granted, but if it does, you can go with him to Canada and he can wait out the process there.
I thought about this option, of filing for a travel visa for my spouse but, does this not mean they will then be considered inland? intead of outland? As I understand it makes a difference in this case, under a different category. I'm not sure thought.
