Just to add, I received Sponsorship Approval months ago, and my wife is at the Background Check stage.
I’d treat this as if they’re worried that you’re going to leave when your partners visitor visa expires.
Anyway, for extra documents to prove that you intend to live there, you want to include a detailed plan of what your plans are:
- Mention you’ve already landed back in Canada due to unforeseen circumastances.
- You’re now looking for a job locally to you (Include job searches for your field around your local area as additional docs)
- Rental searches around your area, possibly highlighting schools and daycares you’re interested in.
- What your plans for your partner are once she has PR.
Good additional documents can be:
- Screenshots of job searches.
- Screenshots of rental searches.
- Letters from your family and friends about coming / being home and your intent to stay there. I’d even include a fresh letter from your mother stating once again that she’s happy for you to stay there for the foreseeable future.
- I’d include your plane tickets you bought to come back to Canada.
- Screenshots of any off the cuff discussions you’ve had with friends and family about being back.
Good luck.
