The answer
Tax residency is fact-specific. If the owner becomes non-resident, Canadian rental income can trigger withholding, agent, NR6 and possible section 216 filing requirements; future sale can require section 116 planning. Lender, insurer, condo, management, principal-residence and change-of-use questions also remain.
Calgary-specific context
Do not wait until the first rent payment or departure tax return to identify the withholding owner.
What to do next
Obtain cross-border tax, legal, lender, insurer and management advice before departure or tenant possession.
