Hi how long is bcakground checking?
they said spousal sponsorship takes 10
Months, in my case my application is 10
Months now on Oct 7.
I'd suggest you read other threads here. The 10 months total is an estimate. Many applications take less than 10 months, some (perhaps 20%) go over 10 months, a small percentage take considerably longer. My rule of thumb right now might be that going to ~12-13 months may not be a serious problem, beyond ~15 months puts it in rare category.
You can order gcms notes (google or search here), write your MP, or call IRCC. None of these are likely to speed things up, but occasionally can provide info on what the issue might be (and rarely help one solve it).
My guess is that most that go seriously over have either a) problems that might lead to refusal or b) security issues. Security can be related to country of origin, but very hard to say how long it can take to get resolved.
