Non-residents of Canada have different qualifications for obtaining a residential mortgage. The best thing that you can do is talk to your mortgage consultant to understand what documents are required.
Each lender will have different qualifications, but there are a few things that are pretty generalized across the board.
- Valid work visa (Work Permit #1442) or permanent residence form (IMM 5292/IMM 5688).
- Proof of employment and income
- Canadian Credit history report
Other documents vary depending on if you are obtaining an insured or non-insured mortgage.
