Two words on your policy that decide how much of a claim you get back. Most owners assume replacement cost means the insurer pays to put everything back. It can. There are three conditions attached, and they are the reason cheques come in smaller than expected.
What those two words do to a claim.
Replacement cost is not a value your building has. It is a way of settling a claim. It tells you how the insurer will work out what they owe you after a fire, a flood or a hailstorm, and it is the single most consequential thing on a commercial property policy that most owners have never had explained to them.
The two ways a property claim gets paid
Every property policy settles on one of two bases, and it's listed on the declarations page.
- Actual cash value. What it costs to replace the damaged property, minus an amount for its age and condition. A twenty-year-old roof is paid as a twenty-year-old roof, not as a new one.
- Replacement cost. What it costs to repair or rebuild with materials of similar kind and quality, with nothing taken off for age or wear. A new roof for the old one.
On the same loss those two numbers can be far apart, and the older your building and its systems are, the further apart they get. It is worth knowing that on several Canadian commercial wordings actual cash value is what the base form gives you, and replacement cost is an upgrade somebody has to have asked for.
Replacement cost only pays in full if you rebuild
This is the condition that surprises people, and it is written into the wording. Canadian commercial policies tie the replacement cost payment to repairing or replacing the property and not replacing usually results in instead receiving actual cash value.
So the money normally arrives in two parts. The first cheque is the actual cash value. The rest, the part that was held back for depreciation, comes once you have done the work and can show it. It is what the coverage was written to do: put the building back, rather than hand you its value in cash.
Two things follow from that, and both matter. If you decide not to rebuild, you generally keep the actual cash value and lose the rest, so make that decision on purpose. And if you delay the work for a long time without a good reason, you can lose the replacement cost settlement you were entitled to.
Three numbers people confuse with it
Every one of these gets inappropriately used as a building limit, and every one of them leaves owners short.
- Market value. What a buyer would pay for the property. It includes the land, which does not burn, and it reflects what the market thinks of the location rather than what the structure costs to build. In parts of Alberta rebuilding costs more than the building would sell for.
- The price you paid. A historical fact about a transaction. It says nothing about what construction costs today.
- The assessed value. A figure the municipality produces so it can tax you. It was never meant to be an insurance limit and it does not behave like one.
A builder’s price per square foot is closer, but it is still not the answer. Putting up a new building on a clear lot is a different job from rebuilding a damaged one: somebody has to demolish and haul away what is left, the building has to be redrawn and re-permitted, it has to meet today’s rules rather than the ones it was built under, and prices keep moving while all that happens.
What a short limit does to a claim
Insuring for less than it costs to rebuild costs you in two separate ways, and most owners only know about the first.
The obvious one is the ceiling. Your policy will never pay more than the limit, so a building insured for $600,000 that costs $1,000,000 to rebuild leaves you $400,000 short if it burns to the ground.
The one that catches people is coinsurance. Most commercial property policies carry a clause requiring you to insure to a set percentage of value, commonly 80%, 90% or 100%. Fall short of it and the insurer reduces every partial claim by the same proportion you fell short. Most claims are partial, so this is the version that happens. Our guide to coinsurance walks through what a shortfall does to a real claim.
The Alberta building code gap
A building damaged today has to be repaired to the code in force today. In Alberta that is the National Building Code 2023 Alberta Edition, which has applied since 1 May 2024, and it does not care what the rules were when your building went up in 1987.
Here is the problem. Standard Canadian commercial wordings exclude loss arising from the enforcement of a by-law or regulation. The policy puts your building back the way it was. It does not, on its own, pay the extra cost of meeting requirements that did not exist when it was built: barrier-free access, current fire separations, current energy and life-safety standards.
What closes that gap is a by-law endorsement. It usually covers three things: the extra cost of building to current requirements, the cost of demolishing and removing undamaged parts of the building you are ordered to take down, and the value of that undamaged portion you lose. On an older building this is not a small item.
One honest limit, and it comes from an Alberta case that went to the Court of Appeal. By-law coverage responds to the extra cost that the insured damage causes. It does not pay to fix a code problem that was already there and simply came to light because someone was up on the roof after a loss. If your building has a known deficiency, the time to deal with it is now, not through a claim.
If you lease, this is still your problem
Tenants sometimes assume the building limit is the landlord’s concern. The building is. Your improvements are not.
The walls, the kitchen, the treatment rooms, the millwork, the wiring you put in for your equipment: that is your property to insure, and in a restaurant or a clinic the fit-out can cost more per square foot than the shell around it. Which side insures what is set by the lease, and leases are inconsistent about it. It is worth ten minutes with your broker and the lease in front of you, because the two failure modes are paying twice for the same thing and discovering after a fire that neither of you insured it.
Why the number goes out of date on its own
Almost nobody sets out to be underinsured. The limit was right when it was set, and then it stopped being right without anyone touching the policy.
- Construction got more expensive. Statistics Canada had non-residential construction prices up 3.5% over the year to mid-2026, and Calgary and Edmonton are running at 4% or more. Alberta has been moving faster than the national picture, so a national rule of thumb understates it here.
- You changed the building. An addition, a finished mezzanine, a new roof, an upgraded electrical service. Every one of those raises what it costs to rebuild, and none of them raises your limit unless somebody tells the insurer.
- The rules changed. Codes move. The gap between what your building is and what a new one has to be gets wider every year you own it.
What to do about it
None of this needs a formal exercise or a specialist. It needs a conversation, once a year, with somebody who reads the policy.
- Ask which basis you are on. Replacement cost or actual cash value, for the building and separately for the contents and equipment. They are not always the same.
- Ask whether by-law coverage is on the policy, and for how much. On an older building, ask whether the amount is realistic.
- Tell your broker when the building changes, at the time it changes. A renovation is a phone call, not a note to raise at renewal.
- Ask about a stated amount clause. On some policies you declare a value the insurer accepts, which takes the coinsurance penalty off the table. Whether it is available depends on the insurer and the building.
- Ask about inflation protection. Some policies raise the limit through the year in step with a construction cost index, which slows the drift between renewals.
The one thing worth remembering
Replacement cost describes what the insurer will do, not what your building is worth. It pays without a deduction for age, it pays in full only when the work is actually done, and it does not by itself pay for the building rules that changed while you owned the place. Knowing those three things before a loss is most of the value on this page.
