What does commercial property insurance cover?

It covers the physical assets of a business against insured damage: the building if you own it, tenant's improvements, equipment, furniture, stock, and customers' property in your care. Most Canadian policies are written on a broad form that covers all direct physical loss except listed exclusions, and can add business interruption to replace lost income.

I lease my space. Do I still need property insurance?

Yes. Your landlord's policy covers the building, not your contents, equipment, stock, or the improvements you paid for, and most leases require you to insure those and carry liability. The lease's insurance clause sets the exact requirements, so we build your policy to match it.

Does commercial property insurance cover flood?

Not automatically. Overland flood and sewer backup are usually excluded unless you add them by endorsement, often with their own deductibles or sublimits. Availability depends on your location's flood risk, so ask for both explicitly and check the declarations page.

What is coinsurance, and how can it reduce my claim?

A coinsurance clause requires you to insure to a set percentage of your property's value, commonly 80% or 90%. If you carry less, the insurer reduces every claim in the same proportion, even small ones. For example, carrying two-thirds of the required amount means a $300,000 loss pays about $200,000 before the deductible.

What is the difference between replacement cost and actual cash value?

Replacement cost pays what it costs to repair or replace with like kind and quality, without deducting for age. Actual cash value deducts depreciation, so older buildings and equipment can settle well below what replacing them costs. Replacement cost is usually paid only once you actually repair or replace.

Does it cover lost income after a fire?

Only if you have business interruption coverage on the policy. It replaces lost profit and pays continuing expenses like rent, loan payments, and key payroll for the indemnity period you choose. Building owners can insure lost rent the same way through rental income coverage.

Is equipment breakdown covered?

Not by a standard property form, which excludes mechanical and electrical breakdown. Equipment breakdown coverage insures sudden failure of boilers, HVAC, electrical panels, production machinery, and computers, and can include the resulting lost income.

Is inventory covered at cost or retail value?

Most policies value stock at your cost to replace it, not its selling price. Finished goods you've already sold can sometimes be insured at selling price by endorsement. Stock values that swing with the season or with tariffs need a limit set at the peak, or a reporting form.

How much does commercial property insurance cost?

It is priced as a rate per $100 of insured value, set mainly by construction, occupancy, fire protection, and exposure, plus your deductible and claims history. A sprinklered masonry office prices very differently from a frame restaurant. We compare 17 insurers to find the best rate for your specific property.

Do I need to tell my insurer if my building will be vacant or renovated?

Yes, in writing and in advance. Most policies restrict coverage once a building is vacant for more than 30 days, and in Ontario a material change in risk within your control must be reported to the insurer. Renovations and new tenants can also change the risk.

In short

Commercial property insurance pays to repair or replace the physical assets a business owns or is responsible for, including its building, leasehold improvements, equipment, inventory and furnishings, after insured damage such as fire, windstorm, theft or water escape. Most Canadian policies are written on a broad form that covers all direct physical loss except what is excluded, and can be extended to replace lost income while the business recovers.

Commercial property insurance protects the physical assets your business depends on: your building, equipment, inventory, and improvements. Paired with business interruption coverage, it also replaces the income you'd lose if a fire, storm, or other insured event forced you to close.

Most property claims that go wrong don't fail because the business had no insurance. They fail on an outdated limit, a coinsurance penalty, a missing flood or by-law endorsement, or an income period that ran out before the rebuild did. We set up property coverage to avoid exactly those outcomes, whether you own your building or lease your space.

What's covered

Buildings, permanent fixtures, and building services
Tenant's improvements and betterments
Equipment, machinery, furniture, and computers
Stock and inventory, including customers' goods in your care
Business interruption, extra expense, and rental income
By-law, demolition, and increased cost of construction
Optional flood, sewer backup, earthquake, and equipment breakdown

What commercial property insurance covers

A commercial property policy insures the tangible things your business would need to replace after a loss. The policy lists each category of property separately, with its own limit, so the first job is making sure every category you actually have is on the declarations page.

Building: the structure, permanent fixtures, and building services such as heating, plumbing and electrical systems. Insured by whoever owns the building or has agreed to insure it under the lease.
Tenant's improvements and betterments: the fit-out a tenant pays for, such as a restaurant kitchen, partition walls or flooring. Usually the tenant's to insure, because it's the tenant's money in the walls.
Equipment and machinery: computers, tools, production equipment and furniture. Mechanical or electrical breakdown needs separate equipment breakdown coverage.
Stock and inventory: raw materials, work in progress and finished goods, at the valuation the policy specifies.
Property of others: customers' goods in your care, custody or control, which a standard contents limit may not include.
Outdoor property and signs: often covered only to a modest sublimit unless scheduled.
Income: business interruption or rental income coverage, which replaces lost revenue and pays continuing expenses while you recover from an insured loss.

If you lease, read the insurance clause in your lease before anything else. It decides who insures the building, who insures the improvements, and whether you must name the landlord on your policy. Our guide to the commercial lease insurance clause walks through it line by line.

Who needs commercial property insurance

Any business with physical assets it couldn't comfortably replace out of pocket. In practice that includes:

Owners of commercial buildings, plazas, industrial units and mixed-use properties, usually on a realty package with rental income coverage.
Commercial tenants, for contents, stock, equipment and improvements, typically through a tenant package built to the lease.
Manufacturers, wholesalers and distributors, whose stock values move with the market and whose machinery drives revenue.
Retailers, restaurants, clinics and offices, where a fire or water loss stops trading as well as damaging property.
Home-based businesses, because a home policy typically excludes or tightly limits business property. See home-based business insurance.

Broad form vs. named perils: what triggers coverage

Every property policy answers one question first: which causes of loss are covered? Canadian commercial policies answer it in one of two ways.

The two ways a commercial property policy defines covered losses
	Broad form (all risks)	Named perils
What's covered	Any direct physical loss or damage unless the policy excludes it	Only the causes of loss the policy lists
Typical listed perils	Not applicable; coverage is open unless excluded	Fire, lightning, explosion, smoke, windstorm, hail, riot, vandalism, impact by vehicle or aircraft, leakage from fire protective equipment
Who must prove what	You show a physical loss happened; the insurer must show an exclusion applies	You must show the loss was caused by a listed peril
Usually fits	Most businesses with an insurable building or contents	Higher-risk, vacant or hard-to-place property, or where cost is the priority

Broad form is the standard for most businesses and the stronger position at claim time. A named perils form isn't wrong, but it should be a deliberate choice, not something discovered after a loss the list doesn't mention.

Common exclusions, and how to close the gaps

Even a broad form excludes a predictable set of losses. Some can be bought back by endorsement. Others belong on a different policy, and a few aren't insurable at all.

Typical commercial property exclusions and where the cover comes from
Excluded or limited	How to cover it
Overland flood	Flood endorsement, where the insurer offers it at your location; availability and price depend heavily on flood mapping
Sewer backup	Sewer backup endorsement, usually with its own deductible; backflow valves help both cost and availability
Earthquake	Earthquake endorsement with a percentage deductible; most relevant in British Columbia and the western Quebec seismic zone around Ottawa
Mechanical and electrical breakdown	Equipment breakdown coverage
Employee theft and fraud	Commercial crime coverage
Data loss and cyber attack	Cyber liability coverage
Property in transit or at other locations	Transit, off-premises or tools and equipment floater coverage
Losses after the building is vacant for more than 30 days	Tell your broker in advance and arrange a vacancy permit or vacant property policy
Wear and tear, gradual leakage, rot, mould, pests	Not insurable; managed through maintenance

Vacancy is the exclusion that catches the most owners off guard, especially over the winter. Our guide to how the 30-day vacancy clause works explains the wording and the steps that keep a quiet building insured.

Setting your limits: replacement cost, ACV and coinsurance

Your limit is the most the insurer will pay, so it has to reflect what it would actually cost to rebuild and re-equip, not what the property would sell for. Market value includes land, which doesn't burn. Replacement cost includes demolition, debris removal, current construction prices and professional fees, which market value ignores.

Those construction prices keep moving. Statistics Canada's non-residential building construction price index rose 3.5% year over year in the second quarter of 2026. A limit set three or four years ago and only nudged at each renewal can be well short today.

How a loss is valued under the common settlement bases
Valuation	What it pays	Watch for
Replacement cost	The cost to repair or replace with property of like kind and quality, without deducting for age	Usually paid only once you actually repair or replace; until then many policies pay actual cash value
Actual cash value	Replacement cost minus depreciation	Older buildings and equipment can settle far below what it costs to replace them
Stated amount	Suspends the coinsurance penalty for the policy term, based on a signed statement of values	The statement has to be realistic, and it lapses if it isn't renewed
Agreed value	A value fixed in advance for specific items such as fine art or specialised equipment	Usually requires an appraisal and is reviewed each term

Coinsurance is the clause that turns an outdated limit into a smaller cheque. Most commercial property policies require you to insure to a set percentage of value, commonly 80% or 90%. If you carry less, every claim is reduced in proportion, even a partial loss well under your limit.

A worked example: your building would cost $2,000,000 to replace and the policy has a 90% coinsurance clause, so you must carry at least $1,800,000. You carry $1,200,000, which is two-thirds of what's required. A $300,000 fire then pays about $200,000, less your deductible. The $100,000 difference is yours, even though the loss was nowhere near your limit.

The fix is cheap compared with the penalty: a professional appraisal every few years, indexing in between, and a stated amount clause where the insurer offers one.

By-law coverage: rebuilding to today's code

When an older building is damaged, the municipality can require the repair to meet current building, fire and accessibility codes. It can also require the undamaged part of a heavily damaged building to be demolished and rebuilt. Standard property wording typically excludes those extra costs.

By-law coverage closes that gap. It usually comes in three parts: the value of the undamaged portion you're forced to demolish, the cost of demolishing it, and the increased cost of construction to meet code. Buildings from before the 1990s, with older electrical systems, limited fire separation or no elevator, are the obvious candidates.

Business interruption: insuring the income, not just the building

A fire can stop revenue for months while fixed costs keep running. Business interruption coverage is what keeps the business solvent through the rebuild, and in many serious losses it's the larger half of the claim.

Profits or gross earnings form: replaces lost net profit and pays continuing expenses such as rent, loan payments and key payroll.
Indemnity period: the length of time the coverage pays. Twelve months is common, but a realistic timeline for adjustment, design, permits, contractors, the rebuild and winning customers back often runs longer.
Extra expense: the cost of keeping trading, such as temporary premises, rented equipment or overtime, while repairs are made.
Rental income: the building owner's version, replacing rent from units that can't be occupied. Owners on net leases should also insure the recoverable operating costs.
Civil authority and contingent business interruption: income lost because authorities block access, or because a key supplier or customer suffers the loss instead of you.

Weather, water and climate risk

Weather is now the main driver of large property losses in Canada. Insured severe-weather losses topped $2.4 billion in 2025, including about $490 million from the late-March ice storm in Ontario and Quebec, according to CatIQ figures released by the Insurance Bureau of Canada. Catastrophe losses over 2016 to 2025 came to roughly $37 billion, against about $14 billion in the previous decade after adjusting for inflation.

For a business, that shows up as roof collapse under snow and ice, frozen pipes in quiet buildings, sewer backup after cloudbursts, and wind damage to roofs and signs. Insurers increasingly price and decline by postal code, so the measures you can document matter: water leak sensors with automatic shut-off valves, low-temperature alarms, backflow valves, monitored sprinklers and regular roof inspections. Our winterizing checklist covers the seasonal work.

What commercial property insurance costs

Property premiums are calculated as a rate per $100 of insured value, multiplied across each limit. That rate comes from how underwriters assess the risk, which the industry summarises as COPE.

Construction: frame, masonry or non-combustible construction, roof type, and the age of the roof, wiring, plumbing and heating.
Occupancy: what happens inside. A restaurant, auto body shop or woodworker carries more fire risk than an office, and in a multi-tenant building the riskiest tenant affects everyone's rate.
Protection: distance to a hydrant and fire hall, the municipality's fire protection grade, sprinklers, and monitored fire and intrusion alarms.
Exposure: neighbouring buildings, flood and wildfire mapping, crime rates, and earthquake zone.

Beyond COPE, the deductible you choose, your claims history and the market itself move the price. The market is currently in buyers' favour: Marsh's Global Insurance Market Index put Canadian commercial property rates down 8% in the third quarter of 2026, the steepest fall of any major line. That makes now a good time to fix limits and gaps without a large premium jump.

A reliable quote needs a reliable submission: building updates by year, square footage, construction details, protection, a statement of values and five years of loss history. We prepare it with you, then market it to the insurers whose appetite fits your property.

Provincial rules that affect your coverage

In Ontario, fire insurance contracts carry statutory conditions set by the Insurance Act, and the other common-law provinces have close equivalents. Two matter most day to day.

Material change: a change material to the risk that's within your control and knowledge, such as a building going vacant, a new high-hazard tenant or a major renovation, must be reported to the insurer in writing. In Royal Bank of Canada v. State Farm (2004), the Court of Appeal for Ontario held that failing to report a vacancy defeated the claim.
Proof of loss and timing: the conditions set out how and when you must notify the insurer and file a proof of loss after a claim. Late notice can complicate even a clearly covered loss.

The practical rule is simple: tell your broker before anything about the property changes, not at renewal.

How we place commercial property insurance

Insurabiz is an independent brokerage that works only in business insurance. We don't work for one insurer, so our job is to find the wording and price that fit your property, then keep them fitting.

1Inventory: we confirm every category of property you have and who is responsible for it under any lease or mortgage.
2Valuation: we test your limits against current replacement cost and flag coinsurance, by-law and income gaps before they cost you.
3Submission: we build a full underwriting submission covering construction, occupancy, protection and exposure, with your updates and loss-control measures documented.
4Marketing: we take it to the insurers on our panel of 17 whose appetite fits your building and occupancy.
5Comparison: we compare quotes on wording, deductibles, sublimits and conditions, not just the premium, and explain the differences in plain language.
6Review: we revisit values, tenants and exposures every year, and you call us whenever something changes mid-term.

Owners with several locations can often get better terms on a single blanket policy. See bundle and save for how we package property with liability and auto.

If you have a loss

1Make everyone safe and call emergency services if needed.
2Protect the property from further damage. Shut off water, board openings and tarp the roof. Most policies require it, and reasonable costs are usually claimable.
3Notify your broker and insurer promptly, and in writing.
4Document everything: photos and video before cleanup, damaged items kept until the adjuster has seen them, and receipts for every emergency expense.
5Track lost income and extra expenses from day one if you have business interruption coverage.

Our claims team works alongside you and the adjuster from first notice to final settlement.
