Renting a room works best when the home layout genuinely supports privacy for both parties and the income meaningfully offsets costs, but it also means becoming a landlord under the Residential Tenancies Act, 2006, with the responsibilities and paperwork that come with an active tenancy.
Selling removes that ongoing management entirely and, per the Canada Revenue Agency's principal residence exemption, generally comes with no capital gains tax on a genuine principal residence, which is a meaningful advantage over holding an asset that needs continued upkeep.
If staying in the home is not the real priority, selling usually produces a cleaner outcome than managing a tenant for modest income. Get your hand-reviewed valuation from Joel Dyck.
