Webfrom is just the generic webform for any questions, comments or updates for IRCC. You are getting close to the one year mark so I would update with some proof of your relocation as soon as possible to hopefully prevent a request for more proof that you and your spouse will be relocating back to Canada. Do you have proof of a signed lease even if you haven’t moved in? That can be attached and submitted via webform. Any accounts or utilities set up in your name like bank account, phone or credit card? How did you enter Canada? Proof that you entered Canada can help. Did you leave your job in the US? That can be provided as proof. Find a new job in Canada or proof that you are applying for them would be proof as well. A letter from your mother can be included saying that she is happy to provide you with a temporary home in Canada before you find your own but family letters are weak proof in general. Think the goal is to provide some evidence to at least prove that you have moved back to Canada and then you can add more evidence as you start to collect more.
I see! Do you have a link to the form, or is it somewhere within the GCkey website? I just opened a bank account, and I'm arbitrarily close to getting my driver's license and Canadian plates, just have a few small-ish hoops to jump through still. I entered Canada by land border, and have proof of my imported goods complete w/ border stamp, along with some receipts from a brokerage service that I used for my car. I've started a new job, and won't get a paycheck with them until a week from this coming Friday, but I can get a letter from them. My mom would be happy to write a letter, but like you said, I'd be better off having more concrete proof.
I'll start pulling that stuff together. In terms of the actual "change of address" link that was posted above, should I do that once I'm in my permanent address, or should I submit it once for my temp address, and submit it again once I move to my final address?
Let me know. Thanks for all of the help, Canuck! (You're always doing heavy lifting here.)
