Canada desperately needs more housing.
asserted
Canada → need → housing
However, the residential construction industry is caught in a perfect storm of rising costs.
asserted
industry → catch → costs
Just as governments are calling on the industry to dramatically increase supply, a new collection of economic and trade pressures threatens to push us in precisely the opposite direction.
asserted
collection → call → direction

The continuing Canada-U.S. tariff battle, a dramatic surge in diesel prices and the indefinite idling of galvanized steel production at Stelco in Hamilton threaten to dramatically escalate costs.
asserted
battle → continue → costs
Each presents a serious challenge on its own.
asserted
Each → present → own
Together, they will increase the cost of building, make projects more difficult to finance and further undermine the economics of new housing.
asserted
projects → increase → housing
And ultimately, builders won’t be the only ones paying.
asserted
builders → pay → ?
Homebuyers and renters will pick up the tab.
asserted
Homebuyers → pick → tab
A CMHC report indicates that inflation-adjusted house prices in Canada have more than doubled since 2005, rising faster than in most developed countries.
asserted
prices → indicate → countries
Meanwhile, nearly five new residents have been added for every house completed in 2023 and 2024.
asserted
residents → add → 2023
We should be removing obstacles to construction and reducing the cost of producing housing.
asserted
We → remove → housing
Instead, the industry is confronting another round of cost increases.
asserted
industry → confront → increases
The cross-border construction supply chain is highly integrated.
asserted
chain → integrate → ?
Tariffs and counter-tariffs affect structural steel, rebar, pipe, fasteners, lumber, engineered wood, flooring and manufactured components such as HVAC equipment, elevators, electrical products and appliances.
asserted
Tariffs → affect → equipment
A RESCON analysis estimates measures introduced Sept. 8 add roughly $9,000 to $14,000 to the cost of a typical Ontario single-detached home and $18,000 to $20,000 to a mid-rise unit.
asserted
measures → estimate → unit
That’s on top of $15,000 to $25,000 already added to Ontario homes by measures introduced in March 2025.
asserted
That → ’ → March
Builders cannot indefinitely absorb tens of thousands of dollars in additional costs per unit, particularly when financing and carrying costs remain high and sales have weakened.
asserted
sales → absorb → unit
Eventually, those costs must show up somewhere.
asserted
costs → show → ?
That means higher prices for purchasers, higher rents for tenants or, increasingly, projects that simply don’t proceed.
asserted
that → mean → tenants
Diesel is adding another layer to the problem.
asserted
Diesel → add → problem
It is the dominant energy source on construction sites, powering excavators, loaders and other heavy equipment.
asserted
It → power → excavators
But its impact doesn’t end at the jobsite gate.
asserted
impact → end → gate
Diesel is also embedded in virtually everything transported to a construction project.
asserted
Diesel → embed → project
With diesel prices roughly 70 per cent or more above year-ago levels, the shock is flowing through equipment operating costs, freight and delivery, and fuel-intensive products such as aggregates, cement, asphalt and precast concrete.
asserted
shock → flow → aggregates
The national average retail diesel price approached $2.60 a litre in mid-October, more than $1.06 above a year earlier.
asserted
price → approach → October
Consider what that means across an industry that consumed approximately 1.72 billion litres of diesel in 2023.
asserted
that → consider → 2023
At an additional $1.06 per litre, the arithmetic points to about $1.8 billion in extra direct fuel costs on an annualized basis.
asserted
arithmetic → point → basis
Up to 60 per cent of the cost of aggregates can be tied to transportation, while higher fuel costs are already producing surcharges on products such as cement.
asserted
costs → tie → cement
Housing doesn’t get built without moving people, equipment and enormous quantities of materials.
asserted
Housing → build → materials
When the cost of moving all three rises, the cost of a home inevitably follows.
asserted
cost → move → home
Stelco indefinitely idled its Hamilton cold-rolled and galvanized production lines on Oct. 9, affecting up to 500 jobs and taking an important source of domestic galvanized steel out of the market.
asserted
Stelco → idle → market
Galvanized steel is used for steel studs and framing, HVAC ductwork, roofing, flashing, siding trim, joist hangers, connectors and decking.
asserted
steel → use → studs
The consequences of reduced domestic availability will be higher prices and longer lead times, with mid- and high-rise construction particularly exposed.
asserted
construction → reduce → availability
Dofasco is rationing orders, while steel imported above federal quotas faces a 50-per-cent surtax.
asserted
steel → ration → surtax
We are presently in a housing crisis and have ambitious construction targets.
asserted
We → have → targets
Yet the economics of actually producing those homes continue to become more difficult.
asserted
economics → produce → homes
Against a 2025 target of 150,000 new homes, the province recorded 86,760 – and that’s with basement and laneway units, long-term care beds, retirement homes and student housing added into the mix.
asserted
that → record → mix
The GTA high-rise market, for one, is flashing an unmistakable warning signal.
asserted
market → flash → signal
Just 129 new high-rise units were sold in September, 40 per cent below September 2025 and 90 per cent below the 10-year average.
asserted
units → sell → average
Those aren’t conditions in which the industry can casually absorb another round of cost increases.
asserted
industry → absorb → increases
