Lenders and CMHC both define occupied as your principal residence, not a token stay, and rules around misrepresenting occupancy are taken seriously since insurers price owner-occupied risk very differently from investment risk. Moving out shortly after closing without disclosing that plan upfront is exactly the kind of thing that creates problems later.
If your actual plan is to never live there, budget from the start for investment property terms: typically at least 20 percent down and a different, usually higher, interest rate than an owner-occupied purchase would get. Run both scenarios with a lender before you commit to either one.
