Home insurance when you rent out a basement suite in Canada

General information only. This guide explains, in general terms, how renting out part of a Canadian home interacts with a home insurance policy. It is not insurance advice, it does not recommend any insurer or product, and it is not written by a broker or agent. Insurers set their own rules, and those rules differ — confirm anything that matters with your own insurer or broker, and treat your policy documents as the final word.

Do you still live there? That is the first question

Before premium, before paperwork, an insurer sorting out a basement suite wants one answer: is the home still your home? Almost everything that follows hangs off that answer, because the policy route for an owner who lives upstairs is a different product from the route for an owner who has moved out entirely.

The trap sits underneath the question. A home policy was priced and written for the household named in it. The Insurance Bureau of Canada's guidance is direct about the sequence: tell your insurance representative before your living arrangement changes, and keep a written record of the notification. The warning that follows it is the one to take seriously — failing to disclose an occupancy change may void the policy. “May void” does not mean a smaller cheque on one claim. It means the contract the household has been paying for may not respond at all, at the moment it is needed most.

So the order of operations matters more than any single coverage detail. Notification comes before the tenant moves in, not at the next renewal, and not after the first rent cheque clears.

Endorsement or landlord policy: decide by living arrangement

The middle row carries a second, insurer-specific detail worth knowing as an example of how rules differ: Sonnet states that it only insures rental properties if the primary residence is also insured with Sonnet. That is one insurer's rule, not a national one, and it is printed here for exactly that reason — the household that assumes every insurer will simply add a rental policy may find its own insurer will not, and that discovery belongs before a purchase or a lease, not after.

Proper landlord coverage also does one job a homeowner policy is not built for: per IBC, proper landlord coverage replaces lost rental income after an insured loss. If a fire makes the suite unlivable during repairs, that component is what addresses the rent that stops — a landlord-side exposure that does not exist until the day a tenant moves in.

The fine print with numbers: one household, two roomers, not both

Most landlord guides stay vague about how much renting a personal policy tolerates. One insurer's published answer is unusually concrete, and it is worth reading closely as an illustration of the kind of limit to ask any insurer about. Sonnet's FAQ states that its personal policy covers renting rooms to no more than two roomers or boarders, or one additional unit — a basement apartment is its example — rented to no more than one household. The two arrangements cannot be combined: it is one route or the other, not both together under that policy.

Three practical readings follow, all of them questions to put to your own insurer rather than assumptions to carry:

• A basement suite rented to one household fits the “one additional unit” shape in that example. A suite whose occupancy grows beyond one household is a different shape, and it needs a fresh answer.
• Taking in roomers while also renting a suite is, under that published example, outside the personal policy's stated shape — even if each arrangement looks modest on its own.
• Limits like these live in underwriting answers and FAQs, not in the headline of a policy. No source checked for this guide published a comparable numeric limit for other insurers, so there is no honest cross-insurer table to print here. The gap is the point: ask for your insurer's numbers, in writing.

What your policy will never cover for your tenant

IBC states the boundary plainly: a home policy covers only you, your spouse and your dependants. It does not cover a tenant's contents, and it does not cover the tenant's liability. If the tenant's furniture is destroyed in a loss, that is a claim on the tenant's own insurance, if they have it — not on the landlord's policy. If the tenant is liable for damage or injury, the same boundary applies.

That fact does practical work in a tenancy. A landlord who understands the boundary can say, before move-in and in writing, that the suite's contents are the tenant's to insure. A landlord who discovers the boundary after a loss is delivering the same news at the worst possible time, to a household that can no longer buy cover for a loss that has already happened.

The notification procedure, step by step

This topic does suit a procedure, because the sources describe a sequence with a clear success check at the end:

1. Notify before the change. Tell your insurance representative before the living arrangement changes (IBC), not at renewal. A tenant moving in is the change; the call belongs ahead of it.
2. Keep the written record. IBC advises keeping a written record of the notification. An email or letter you can produce later is the record; a phone call you remember is not.
3. Confirm the route for your arrangement. Living upstairs usually means a homeowner policy plus a rented suite endorsement (LearnOntario); a property you do not live in means a separate rental property policy (Sonnet). Get which route applies to you confirmed, not assumed.
4. Bring the property details to the quote conversation. LearnOntario lists what to have ready: year built, roof age, heating, electrical, and occupancy details. Arriving with those five items shortens the conversation and reduces the chance of a detail surfacing later as a surprise.
5. Ask the two forward questions now. Ask about vacancy — what happens after 30 days unoccupied — and about tenant-theft exclusions (LearnOntario). Both are far easier to price in before a gap between tenants or a loss than to argue about after one.

What success looks like: before the tenant's move-in date, you hold a written confirmation from your insurer naming the suite, the arrangement, and the policy route that covers it — and a dated copy of your own notification sits in the same file.

Between tenants: the vacancy question to ask in advance

Suites sit empty. A tenant leaves, the unit is repainted, the next tenancy starts six weeks later. The insurance question in that gap is vacancy: what does the policy say after the home, or the suite, has been unoccupied for a period? LearnOntario's advice frames it as a specific number to ask about — what happens after 30 days unoccupied — rather than a general worry. Policies differ, and no source checked states a single national vacancy rule for rented suites, so this guide will not invent one.

The habit that covers the gap is the same one that covers the move-in: ask before the vacancy happens, and keep the answer with the written notification record. A household that asks during a tenancy, in a calm week, gets a rule it can plan showings and repairs around. A household that asks after a loss in an empty suite gets an interpretation instead.

General information only — not insurance advice. This site is not a broker, agent, or insurer. Landlord, tenancy and insurance rules vary by insurer and province, and every claim turns on its facts and the policy wording. Talk to a licensed insurance professional about your situation, and treat your own policy document as the final word.
