Yes, but how much more evidence would they have needed? I gave all my bank accounts, my transfer out of money, my job searches, my searches for houses, etc. I didn't want to quit my job as I need my job to stay in Thailand and I won't terminate my lease on the risk that she get denied (which she did). Everybody I spoke with was surprised by the result and also said these requests were highly unreasonable.
I'm not sure who you spoke to. However the requests you received are not at all uncommon in cases where IRCC has concerned the sponsor and applicant don't actually intend to move. Either these were individuals not familiar with Canadian immigration processes - or lawyers looking to get your business.
IMO the issue was most likely the nature of the evidence you provided to support your claims. Since you weren't able to provide the exact evidence IRCC requested, what you provided as an alternative needed to be super strong.
- What evidence exactly did you provide of job searches? What was the exact artifact you submitted to prove this? Did you show email exchanges with future employers? Interest interviews with employers?
- Same for the housing searches. What was the artifact you provided to prove this? Did you provide a signed contract with an RE agent? Emails from your RE agent with information on what's available to buy / rent in your areas of interest and price ranges?
- If there were plans for you to stay with family members when you first arrived, did you provide an affidavit from that family member confirming this arrangement?
The above may really be a pointless discussion unless you decide to apply outland again. If you apply inland, this isn't needed.
I disagree with the above comment that you need to buy a house in Canada to prove you will return. That's absolutely not required. IMO your proof wasn't strong enough. You were trying to prove the right things - but I suspect the actual evidence you provided wasn't strong. That's where this forum could have really helped you.
