What is loss of rents coverage on a commercial policy, and why does it matter to a business that owns and rents out space? Loss of rents coverage is an extension generally designed to help a landlord recover lost rental income after a covered physical loss, such as a fire or a burst pipe, makes a rented unit uninhabitable or unusable. For a small business that depends on rent from a second unit, a basement suite, or an entire commercial building, losing that income on top of repair costs can be the harder problem to manage.
This article looks at what loss of rents coverage typically includes, how a claim is generally calculated, what commonly falls outside it, and where a Canadian landlord is likely to run into the concept.
What Is Loss of Rents Coverage?
Loss of rents coverage is an extension generally included within or added to a commercial property policy that is designed to help replace the rental income a landlord loses when a covered physical loss makes a rented unit uninhabitable or unusable. It typically sits alongside the building and contents coverage on the same policy, and it is built around the idea that a landlord's loss is not only the damaged roof or wall, but also the rent that stops arriving while repairs are underway.
How a Loss of Rents Claim Is Generally Triggered and Calculated
A loss of rents claim typically depends on a covered peril under the property policy causing physical damage that makes a rented unit unfit to occupy. Once that threshold is met, the amount is generally measured against the gross rental income the unit would reasonably have earned over the time reasonably required to repair it, an interval commonly called the indemnity period.
Insurers often reduce that figure by expenses the landlord no longer has to pay while the unit sits empty, such as certain utilities normally covered under the lease. Canadian case law illustrates how closely the calculation can turn on wording: in Shelter Canadian Properties Limited v. Aviva Insurance Company of Canada, 2023 ABCA 74, the Alberta Court of Appeal reviewed how an indemnity for lost rental income after the 2016 Fort McMurray wildfire should account for a later increase in the landlords' overall net rental income. The decision is a reminder that the specific policy definitions, not a general industry assumption, control what a landlord actually recovers.
Documentation plays a bigger role in this kind of claim than many landlords expect. A signed lease, a rent roll showing what comparable units in the same building earn, and recent bank deposits or tax filings are the records an adjuster commonly asks for to support a claimed rental figure. A landlord who keeps that paperwork current typically has an easier time supporting a loss of rents claim than one reconstructing it after the fact.
Vacant Units and Other Common Gaps
A unit that was vacant when the loss happened is a frequent point of confusion. Many policies are still designed to recognize the lost opportunity to rent out that space, even though no tenant was paying rent at the time, though the exact wording and any sub-limit for vacant space vary by insurer. Where a vacant unit is involved, the amount commonly comes down to a fair rental value rather than an actual lease figure, estimated from comparable units in the same building or neighbourhood rather than from a tenant's cheques.
A tenant who simply stops paying rent, with no property damage involved, typically sits outside loss of rents coverage altogether. That kind of loss is commonly addressed through a separate rent default or rent guarantee product, since the trigger is a tenant's non-payment rather than a covered peril damaging the building. Landlords sometimes assume one coverage automatically includes the other, which is a question worth raising directly with a broker before relying on either.
How Loss of Rents Differs From a Tenant's Own Business Interruption Coverage
Loss of rents coverage addresses the landlord's side of a rent relationship: income the landlord would have collected from someone else. A tenant running its own operations out of that same space has a different exposure, covered instead by its own gross earnings and profits forms of business interruption coverage, which is designed to replace the tenant's own lost revenue and extra expenses rather than rent owed to the landlord. The two coverages can respond to the same physical event from opposite sides of the same lease, which is why a landlord and a tenant in the same damaged building may each be dealing with their own broker and their own claim.
Benefits of Loss of Rents Coverage
The practical benefit is cash flow continuity. A landlord facing an unplanned vacancy after a covered loss still has a mortgage, property taxes, and other fixed costs to cover, and loss of rents coverage is generally designed to help bridge that gap while repairs are underway rather than forcing the landlord to draw on savings or a line of credit. It can also reduce the pressure to rush a repair or reopen a unit before it is genuinely ready.
For a landlord who owns more than one tenanted building, this coverage also supports steadier financial planning across the portfolio. A single damaged unit no longer has to pull funds away from maintenance or planned upgrades at other properties, since the lost rent from that one unit is generally what the coverage is designed to replace while the repair is underway.
Where You'll Come Across Loss of Rents Coverage
This coverage tends to surface at a few recognizable moments: buying a rental or mixed-use commercial property, renewing a commercial property insurance policy that includes tenanted space, or dealing with the aftermath of a fire, storm, or vacant building question between tenants. A mortgage lender reviewing a landlord's coverage during a refinancing or an annual covenant check will sometimes ask about it directly, since the lender's own interest in the property depends partly on the rent that keeps the mortgage payments coming.
Talk to a Licensed Broker About Loss of Rents Coverage
Whether loss of rents coverage is built into an existing policy, available as an add-on, or already excluded in a way that matters depends entirely on the specific wording a landlord carries. A broker can review that wording alongside a business's existing business insurance in Canada and help identify whether a rental property's current protection matches how its units are actually used.

Coverage details vary by insurer and by policy, and only the wording of an actual policy and a licensed broker can confirm what applies to a specific situation.
