The Canadian IOS Supply Crisis: Why Yard Space Is Disappearing Across Every Major Market

In 2022, Canadian industrial vacancy hit 1.4% — the tightest on record. Developers responded by building. By 2025, they had delivered 30 million square feet of new space. Vacancy rose to 4.7%. The headlines said the market was softening. The headlines were wrong.

The softening is entirely in traditional warehousing — large-bay speculative buildings stacked along the 401 corridor, purpose-built for e-commerce tenants who are now consolidating. The segment of the market that nobody tracks separately — low-coverage industrial land used for truck parking, equipment staging, and container storage — tells the opposite story. Specialized Industrial vacancy in Canada sits at 2.7%, according to CoStar. Nearly half the national average. Construction starts have collapsed to 20 million square feet, the lowest since 2017. And the forces suppressing IOS supply aren’t cyclical. They’re structural, permanent, and accelerating.

The National Picture: Two Markets in One

Canada's industrial market is bifurcating. The national 4.7% vacancy rate masks a structural split between traditional warehousing (where vacancy is rising as new spec product delivers) and low-coverage industrial land (where supply is tightening further because no one is building it).

CoStar's national data as of Q1 2026 shows the divergence clearly:

The Specialized Industrial category is the closest CoStar proxy for IOS — it includes transport terminals, contractor yards, and heavy equipment facilities. It is not a pure IOS metric: the category also captures heavy manufacturing and specialized enclosed facilities, which means the 2.7% vacancy figure likely understates the true scarcity of open yard space. But even with that dilution, the signal is clear: vacancy in this segment is less than half the Logistics rate (5.7%), rent growth is positive at 3.8% while every other segment is declining, and its construction pipeline (6.6M SF) is a fraction of the logistics pipeline. The supply imbalance will widen, not close.

The broader industrial softening is actually making the IOS problem worse. Every new speculative warehouse that gets built consumes raw land that could have been used for outdoor storage. The mechanism creating more traditional industrial supply is simultaneously destroying potential IOS supply.

Market by Market — Where the Crisis Is Worst

The national data tells part of the story. The submarket data tells the rest. Here is what CoStar shows across Canada's six major industrial markets:

Two patterns jump out of this data.

The rent growth divergence is the story. Ottawa-Gatineau is growing at 2.6%–3.8% across every submarket — the strongest rental performance of any major industrial market in Canada. Edmonton leads nationally at 5.2%–5.7%. Calgary is at 1.7%–2.5%. Every other major market is in negative rent growth territory. The markets where IOS demand is most acute — driven by energy sector logistics in Alberta and federal/distribution demand in the capital — are the ones still tightening. Toronto and Vancouver are softening on headline rent growth, but that softening is concentrated in new large-bay warehouse product, not in heavy-use land.

Raw land pricing tells the development constraint story. In the GTA, shovel-ready industrial employment land in Mississauga averaged $2.4 million per acre in Q1 2025, with individual Brampton transactions exceeding $3.4 million per acre. CBRE’s 2025 national outlook pegged the Canadian average at $1.38 million per acre. In Edmonton, industrial yards lease for approximately $3,200 to $4,000 per acre per month. In Winnipeg, land values sit around $565,000 per acre. The gap between primary and secondary markets is massive — but even at $565,000 per acre, a developer will build a warehouse before leaving the land open. At $2.4 million per acre in the GTA, IOS is economically impossible unless the operator is buying an existing site, not developing a new one.

The truck parking deficit makes this tangible. A 2018 Ontario Ministry of Transportation study identified a shortage of 1,200 to 2,600 truck parking spaces in Southern Ontario alone. Since then, the province has created a total of 13 new spots. Meanwhile, the closure of legacy facilities like the Fifth Wheel Truck Stop in Bowmanville and the loss of the 730 Truck Stop in Cardinal to fire have removed hundreds of existing spaces from the inventory. The Canadian Trucking Alliance’s 2025 federal pre-budget submission warned that the parking deficit is directly contributing to the chronic driver shortage — drivers are leaving the profession because they can’t find safe, legal places to park and rest.

US data from the American Transportation Research Institute shows commercial drivers lose an average of 56 minutes of active drive time per day searching for parking. Applied to the Canadian fleet, that’s millions of dollars in annual productivity loss — a direct tax on the supply chain, paid by every business that moves goods through the country.

Why New IOS Can't Be Built

The supply crisis isn't just about current vacancy. It's about the impossibility of adding new supply. Three forces guarantee that the deficit will widen.

Land pricing has crossed the threshold. In the GTA, shovel-ready industrial land in Mississauga averaged $2.4 million per acre in Q1 2025. A January 2025 Brampton transaction closed at $3.4 million per acre. At those prices, a developer is economically compelled to maximize the building footprint — constructing a 40–50% coverage warehouse to amortize the land cost across maximum leasable square footage. The required yield-on-cost to service a $2.4M-per-acre land basis simply cannot be achieved by leaving 80–90% of the site as open yard. IOS can’t compete with warehousing for the same dirt in primary markets. In secondary markets like Edmonton ($3,200–$4,000/acre/month lease rates) or Winnipeg ($565,000/acre land values), the math still works — but those markets can’t serve the last-mile logistics demand concentrated in Southern Ontario and the Lower Mainland.

Highest and Best Use erosion is permanent and accelerating. In Vancouver, the City Council approved a 25-storey residential tower on protected industrial land at 320-360 West 2nd Avenue in January 2026 — over the explicit objection of City planning staff who warned it would set a precedent for speculative rezoning across the region. Five additional industrial sites are now under formal review for residential conversion, including the 8-acre former Molson Coors brewery. In the GTA, Metrolinx transit corridors are triggering mandatory residential density around Major Transit Station Areas, systematically converting industrial land along the Ontario Line, Eglinton Crosstown, and GO Transit expansion routes. Every acre rezoned to residential is an acre permanently removed from IOS supply.

The entitlement timeline kills development feasibility. Even in secondary markets where land is affordable, bringing a new IOS site from raw land to operational status in Ontario takes 3 to 5 years. Site Plan Approval under Section 41 of the Planning Act requires engineered drainage plans, environmental assessments, and municipal design reviews. NIMBYism from adjacent residential communities adds further delays. The regulatory timeline alone ensures no rapid supply response is possible, regardless of how much capital is available.

The Construction Pipeline Confirms It

The numbers are unambiguous. Canada delivered 30.4 million square feet of new industrial space in the past 12 months — but construction starts in 2025 collapsed to 20 million square feet, the lowest since 2017. The pipeline is contracting at the exact moment demand for heavy-use industrial land is intensifying.

Net absorption nationally was 9.4 million square feet over the same period, with deliveries outpacing absorption roughly 3:1. But this ratio is driven entirely by the large-bay logistics segment. Specialized Industrial — the IOS-adjacent category — had positive net absorption of 1.5 million square feet against just 442,000 square feet of new deliveries. Demand is outrunning supply by more than 3:1 in the segment that matters for outdoor storage.

The investment market has cooled correspondingly. Only $11.3 billion in industrial assets traded nationally over the past year, well below the five-year average of $15.2 billion. The market cap rate compressed to 5.7%, with Toronto and Vancouver prime assets trading below 5%. Owners are holding because they know the supply constraint protects their asset values. When institutional investors see a market where new supply can’t be built, existing owners don’t sell — they raise rents.

The institutional capital flow reinforces the constraint. Choice Properties REIT — one of Canada’s largest — acquired eight IOS sites nationally for $162 million in the first half of 2025. PGIM provided $103 million in acquisition financing to Alterra IOS in March 2026 against a 23-asset portfolio. Zenith IOS formed a $700 million joint venture with J.P. Morgan. When well-capitalized aggregators buy up the existing fragmented supply, the amount of IOS available for independent lease contracts shrinks further. The capital that validates the asset class simultaneously intensifies the crisis for the operators who need the space.

Montreal is the one market where the data tells a different story. Vacancy rates range from 5.4% to 10.5% across core submarkets, with rent declines of 4.7% to 6.4% — the steepest negative rent growth in the country. Dorval-Lachine recorded negative 1.9 million square feet of net absorption. But even in Montreal, the outlying heavy industrial submarkets are tight: Drummondville at 1.5% vacancy, Laurentides-Lanaudier̀e at 2.0%. The pattern holds — wherever heavy-use industrial land concentrates, vacancy compresses toward zero regardless of what the broader market does.

What This Means for the Canadian IOS Market

The Canadian IOS supply crisis is not a market correction waiting to resolve. It is a structural condition embedded in the physical geography, municipal zoning framework, and land economics of every major logistics corridor in the country. The data is unambiguous: Specialized Industrial vacancy at 2.7% nationally, submarket vacancies at or near zero in every major metro's heavy industrial corridors, land prices that prohibit new IOS development in the GTA and Vancouver, a construction pipeline in freefall, and institutional capital aggregating the existing supply faster than the market can create new product.

For tenants, the implication is that lead times for securing compliant IOS space will continue to lengthen, and lease rates in constrained corridors will continue to climb — particularly in Ottawa and Alberta where rent growth is already outpacing every other Canadian market.

For landlords sitting on underutilized industrial land, the data says your dirt is worth more than you think. The structural supply deficit means properly zoned IOS land carries a scarcity premium that will compound over the next decade.

The supply crisis is not a problem that resolves with patience. It resolves with information. Knowing which corridors still have available inventory, which submarkets are tightening fastest, and which sites carry the zoning to operate legally — that’s the difference between securing space and watching your competitors lock it up first.
