I’d treat this as if they’re worried that you’re going to leave when your partners visitor visa expires.Just to add, I received Sponsorship Approval months ago, and my wife is at the Background Check stage.
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.
