Thanks! what i actually mean is would they need proof of when exactly i'm moving?
I'm going to add the following to support my intention to reside in Ontario:
- strong family ties - my uncle lives there and is a canadian citizen
- possibility of getting a transfer from work to be based in Ontario
- better work opportunities for my husband to find a job (its not easy to find one in montreal since both of us dont speak french)
These are just reasons why you might want to move to Ontario, they do not represent any specific plans or actions you are currently taking to make that happen. Are you - or your husband - conducting a job search in Ontario? Document it. Job transfer? Get a letter from your employer. Looking for housing? Sign a lease. Plan to stay with your uncle for a while? Get a letter from him. If your PR is approved, you are expected to land and reside in Ontario, not move back to Quebec for some time before moving to Ontario.
But is this enough 'proof' or they also need to know specific date when I will move and can sort of hold me against it?
They can't hold it against you. That is why they want to see evidence before they approve. Not saying it won't be approved, but I have seen some cases refused, and would strongly suggest having something more concrete...
