Turning Your Home Into a Rental: Tax, Insurance, and Change of Use

This article is general information, not tax, insurance, or legal advice. A change of use has real tax consequences; confirm your situation with a qualified accountant.

Maybe you are moving but the market is soft, or you want to test being a landlord without selling. Keeping your old home as a rental can be a smart move. But it is not simply handing over the keys. Converting a home you lived in into a rental sets off tax, insurance, mortgage, and legal steps that catch first-time landlords off guard. Here is what to handle first, roughly in order of how expensive it is to get wrong.

The tax event most people do not see coming

This is the big one, because it can cost you with no sale and no cash changing hands. When you convert your principal residence into a rental, the Canada Revenue Agency treats it as a change of use, which is a deemed disposition: you are considered to have sold the home at its fair market value and immediately reacquired it. That can trigger a capital gain, even though you did not sell anything.

There is important relief, though. A subsection 45(2) election lets you defer that deemed disposition and continue to designate the property as your principal residence for up to four more years while it is rented, which can shelter the gain. The catch ties directly to another decision: the election is not available if you claim CCA (depreciation) on the property, which is one more reason to think hard before claiming CCA. This is squarely an accountant conversation before you rent the place out, not after.

One practical consequence: the fair market value at the moment of conversion becomes the starting cost base for the rental period, so document that value now (an appraisal or solid comparables). It determines the eventual capital gain when you truly sell, which we cover in the capital gains guide.

Tell your lender and your insurer (do not skip this)

Two calls that first-time landlords forget, and both can bite:

• Your mortgage. Some mortgages carry owner-occupancy terms, and many lenders expect to be told when a property becomes a rental. Check your agreement rather than assuming.
• Your insurance. This one is not optional. A homeowner policy does not cover a rented property. You need a landlord or rental-dwelling policy, and renting the home out on your old homeowner policy can leave you uncovered when you most need it. Switch it before the tenant moves in.

Set it up as a proper tenancy

You are now running a residential tenancy, which comes with rules:

• Use a written lease. In Ontario, that means the standard lease form.
• Screen tenants consistently and fairly, and collect only the deposits your province allows (in Ontario, a last month's rent deposit, not a damage deposit).
• Know your obligations under the tenancy legislation: maintenance, repairs, notice rules, and the fact that you can no longer simply reclaim the property whenever you like.

Keep records from day one

Because the rental has a fresh cost base (the fair market value at conversion) and its own income and expenses, start a clean record immediately: the conversion-date value, rent received, expenses, and any capital improvements. It is what makes your annual tax filing and the eventual sale straightforward instead of a reconstruction. Keeping that per-property record is exactly what Habyn helps landlords do.

Know what you are signing up for

The last thing to be honest with yourself about: you are becoming a landlord. That means the responsibilities, the tenant-rights rules, and the reality that ending the tenancy later is a legal process, not a decision. For most people it is very manageable, but go in informed rather than surprised.

Frequently asked questions

Do I owe tax when I turn my home into a rental? Possibly. It is a change of use, which the CRA treats as a deemed sale at fair market value, potentially triggering a capital gain even without a sale. A subsection 45(2) election can defer it for up to four years, but not if you claim CCA. Get advice first.

Does my home insurance still cover it once I rent it out? No. A homeowner policy does not cover a rental. You need a landlord policy, and you should switch before the tenant moves in.

Do I have to tell my mortgage lender? Often, yes. Many mortgages have owner-occupancy terms or expect notice when a property becomes a rental. Check your agreement.

What should I document at the start? The property's fair market value on the conversion date (it sets your rental cost base), plus rent, expenses, and improvements from day one.

Turning a home into a rental works best when the tax, insurance, and records are handled up front rather than discovered later. Habyn helps new landlords keep the whole picture in one place from the first day. See how Habyn helps landlords.
