If you have been or are living outside country for more than one year, that's living exclusively outside Canada (in my view).Thank you so much for detailed answer. Yes, I can sponsor, for sure. I was not sure what to say about exclusive live abroad, cause this is not true, at least as I can see it.
For me return to Canada is not just an intend, its a life critical. I have work there and our new office will be ready soon. My son has to finish school. My parents are there. etc etc.
I am 1 year with my fiance for now. Unfortunately I dont see any workarounds.
1. We applied for TRV 11 month ago and it was rejected in Feb this year.
2. I asked MP what do to. IRCC suggested sponsorship. So for common law we need to live 1 year together.
3. Noone answered simple question - where we supposed to live together? As Canadian, I am inadmissible to my fiance country due to COVID, her TRV was rejected. So I am not sure at all what officials are thinking, but its totally inhumane and contradictory.
No big deal: apply as canadian sponsor abroad. if all is as you say, you won't have issues demonstrating intent to return to Canada.
You didn't mention that you are not yet married or officially common law. That makes the timeline more clear - you will have to be out of canada more than one year.
Important note: if you are attmepting to establish common law, my view is you MUST say living outside Canada exclusively - living exclusively together is one way you demonstrate common law. ("We are cohabitating but just in different countries" is, uh, stupid).
Sorry, but I don't follow the rest of your timeline or details (they're not here). You haven't explained why you can't marry. Don't know what inadmissible to her country means. Etc. But that's okay, just can't comment - you need to work these things out.
About all I can say: there is nothing wrong with applying for TRV more than once. Sometimes people have more luck with subsequent attempts (including during covid). Indeed it would be a bit weird if people who REALLY want to live together in Canada didn't try more than once, and it won't hurt your sponsorship app.
