For fifteen years the pitch has been the same in every boardroom west of Winnipeg: build in Alberta, it costs less than Toronto. In 2026 that sentence stopped being reliably true. Calgary construction costs now run above Greater Toronto on retail, warehousing and mid-rise residential, while remaining dramatically below the GTA on institutional, educational and Class A office work.

The cost advantage did not disappear. It moved — from one half of the market to the other. This article sets out where the line now falls, asset class by asset class, with the per-square-foot ranges behind each comparison and an honest account of what the numbers do and do not prove.

What the 2026 Cost Guide actually says

Altus Group published its 2026 Canadian Cost Guide on 23 April 2026, drawing on a proprietary database of 6,652 development projects representing more than 1.63 billion square feet and roughly C$573 billion in collective value.

Its headline finding is a split. Toronto and Vancouver — the country’s two largest markets — were the only major centres where overall construction costs came down over the past year. Calgary, Edmonton, Montreal and Winnipeg all reported increases of 4% or more. Halifax and St. John’s landed in the 1–3% range. Ottawa declined in its most competitive segments.

The causes run in opposite directions. In Toronto, the collapse of new condominium starts freed up trade capacity, and Altus describes pricing at or approaching the most affordable levels in three to five years, with plentiful trade labour availability. In Alberta, skilled trade shortages are named as the single biggest risk to 2026 price volatility — pushing rates up directly through wages and indirectly through schedule risk and reduced bid competition.

That is the mechanism. Alberta did not become expensive in absolute terms. Toronto became competitive, and the gap closed from the other side.

Method note. Every figure in this article is a hard construction cost benchmark in Canadian dollars per square foot, drawn from the 2026 Canadian Cost Guide. Where a percentage appears, it is the comparison of the midpoints of two published ranges — Altus publishes ranges, not midpoints, and the midpoint calculation is ours. The ranges themselves are always shown alongside so you can check the arithmetic.

Where Calgary construction costs now exceed the GTA

These are the categories where the conventional wisdom has already broken.

The pattern is consistent and it is not random. Every category on this list is a building type where the work is repeatable, the structure is simple, the trades are generalist, and the market is competitive. These are precisely the segments where Toronto’s freed-up capacity translated fastest into lower bids — and precisely the segments where Alberta’s trade shortage bites hardest, because there is no specialist scarcity to hide behind.

If you develop industrial, retail or wood-frame residential in Alberta and you are still using a Toronto benchmark as your upper bound, your budget has the sign wrong.

Caveat on the warehouse line. The GTA warehouse range of $75–180 has the widest spread in the entire guide — a factor of 2.40 between low and high. The $75 low end reflects a minimal specification, not a market price. The comparison is arithmetically correct, but the big box and supermarket lines are more defensible in an argument because both ends of both ranges move in the same direction.

Where Calgary construction costs remain far below the GTA

The other half of the market tells the opposite story, and in several categories the gap is enormous.

Again the pattern holds, in reverse. Complexity, constrained urban sites, height, specialist mechanical and electrical scope, bespoke finishes — every one of these is a place where the GTA pays a premium that Alberta does not. Student housing at 45% below and a maintenance facility at 39% below are not marginal differences. They are the difference between a project proceeding and not proceeding.

The categories where Calgary is the most expensive market in Canada

Two public-sector building types break the pattern entirely, and they are worth knowing because almost nobody quotes them.

On both of these, Calgary carries the highest top-of-range figure in the country. A courthouse at $970 per square foot at the high end exceeds the GTA’s $820 ceiling outright. If you are advising a public client on a regional terminal or a justice facility in Alberta, the assumption that the province is the cheap option will not survive contact with the tender.

Seniors housing sits at parity — and that matters right now

Given how much public capital is moving into Alberta’s continuing care sector, the seniors housing lines deserve their own note. They show something close to a dead heat.

There is no Alberta cost advantage in seniors housing. Anyone underwriting a continuing care project in the province on the assumption of a western discount is underwriting a discount that does not exist in the benchmark data.

Infrastructure and site servicing: the range is the story

Below grade and outside the building envelope, the comparison stops being about level and starts being about uncertainty.

Major infrastructure — multi-lane highways, per lane kilometre

Alberta has both the lowest floor and the highest ceiling in the country. The spread between the two is 2.35 times — the widest of the four regions and two-thirds wider than British Columbia’s. On a lane-kilometre basis, the Alberta number is not a benchmark so much as a warning that the benchmark will not do the work for you.

Site servicing — Calgary against Vancouver

Two findings worth pausing on. On a 12-metre arterial road, Calgary’s midpoint of $4,710 per metre sits 8.3% above Vancouver’s $4,350. And on industrial servicing per acre, the Calgary and Vancouver midpoints are $193,250 and $193,300 respectively — a difference of fifty dollars an acre, which is to say no difference at all.

The idea that servicing land is materially cheaper in Alberta than in British Columbia is not supported by the 2026 benchmarks.

Why this changes a feasibility model, not just a talking point

Three practical consequences follow from the split.

The blanket escalation rate is finished. If your 2026 pro forma applies a single percentage to every line, it is wrong in both directions at once: overstating institutional and Class A office, understating retail, warehouse and mid-rise wood frame. National averages, as Altus puts it, tell you less than ever in 2026.

Benchmarking against a distressed market is a trap. Toronto’s numbers came down because the condo pipeline stopped. Using a 2026 Toronto cost per square foot as a sanity check on an Alberta budget means benchmarking against a market in retreat, and the reference point will move again when GTA activity recovers.

Where the range is wide, contingency is the main variable, not a standard percentage. Calgary’s courthouse and regional airport ranges span 1.54 times from low to high, against 1.28 and 1.20 in the GTA. On Alberta multi-lane highways the spread is 2.35 times. In those categories the midpoint carries almost no information, and a fixed contingency percentage applied at concept stage is a formality rather than a control.

How to use these numbers without getting them wrong

These are hard costs only. The ranges exclude land, off-site levies and development charges, permits, professional fees, financing and carrying costs, taxes, contingency, marketing and developer profit. The GTA carries materially higher development charges than Calgary, which means a full pro forma comparison moves some of the lines above — in Alberta’s favour — even where the hard cost comparison does not.

Above-grade rates exclude underground parking. Parking must be calculated separately using the parking rate applied to parking area, not tower area.

Use the correct floor area. Rates apply to gross floor area measured to the outside face of exterior walls. Zoning floor area is not a reliable denominator, because municipal definitions routinely exclude stairs, shafts, service areas and mechanical space. Using the zoning number will understate the project.

Altus publishes Calgary and Edmonton with near-identical ranges. Across most asset classes the two cities carry the same figures, with a handful of residential lines differing by five dollars. This guide cannot be used to compare Calgary against Edmonton, and any argument that tries to is reading precision into the data that is not there.

A conflicting indicator worth knowing. Statistics Canada reported that in the fourth quarter of 2025, residential building construction costs recorded quarterly declines in Calgary, Edmonton and Vancouver — while Altus reports year-over-year increases above 4% for Alberta’s two cities. Different periods and different methodologies can both be true. If you cite both, date them.

Verify against the original before you rely on this. The figures in this article are drawn from the 2026 Canadian Cost Guide. The guide is available directly from Altus Group and takes two minutes to download. For any number you intend to put in front of a client or a lender, read it from the source document rather than from an article — including this one.

The question that actually matters

The debate about whether Alberta is a cheap place to build is over, because the question was always too crude. The 2026 data answers a better one.

Alberta wins on complexity: institutions, universities, civic buildings, Class A office, structured parking, anything where urban constraint and specialist scope drive the number. Alberta no longer wins on volume: warehouses, retail boxes, townhouses, mid-rise wood frame — the building types that made the province’s reputation for affordability in the first place.

So the pitch has to change. Not “we build cheaper than Toronto,” which is now half false and easily checked. But “cheaper at what” — which is a sharper argument, is supported by the published data, and happens to be the answer a serious investor is actually looking for.

Frequently asked questions

Are Calgary construction costs higher than Toronto in 2026? It depends on the asset class. Using the 2026 Canadian Cost Guide midpoints, Calgary runs about 21% above Greater Toronto on big box retail, 20% above on industrial warehouse and 11% above on 13–39 storey condominiums. It runs about 45% below on student residences, 26% below on university teaching space and 11% below on Class A office towers.

What is the construction cost per square foot in Calgary in 2026? It varies widely by building type. Representative 2026 hard cost ranges include $130–175 for an industrial warehouse, $305–375 for a condominium up to 12 storeys, $280–395 for a 5–30 storey Class A office, $370–580 for an elementary school and $1,000–1,600 for an acute care hospital. All figures exclude land, levies, fees, financing and contingency.

Why did construction costs fall in Toronto but rise in Alberta? The drivers are opposite. In Toronto and Vancouver, new condominium starts largely stopped, which freed trade capacity and produced highly competitive bidding from contractors, trades and suppliers. In Alberta, demand from healthcare and institutional projects held up while skilled trade shortages pushed wages and schedule risk higher — identified by Altus as the single biggest risk to 2026 price volatility in the region.

Do the Altus figures include development charges and land? No. The published ranges are hard construction costs only. Land, off-site levies and development charges, permits, professional fees, financing and carrying costs, taxes, contingency, marketing and developer profit all sit outside the rate and must be budgeted separately. This matters for cross-market comparison, because the GTA carries substantially higher municipal charges than Calgary.

Can I use this data to compare Calgary against Edmonton? No. Altus assigns Calgary and Edmonton near-identical ranges across almost every asset class, with only a handful of residential lines differing by about five dollars per square foot. The guide treats the two as effectively one market and offers no basis for distinguishing between them.

Where is Calgary the most expensive market in Canada? On two public-sector building types. Regional airport terminals run $520–800 per square foot in Calgary against $535–640 in the GTA and $430–625 in Vancouver. Court houses run $630–970 against $640–820 in the GTA and $540–750 in Vancouver. In both cases Calgary carries the highest top-of-range figure in the country.
