Canada’s Housing Crisis: Why Prices Doubled and What Build Canada Homes Is Trying to Fix

Canada’s housing crisis is a supply problem that was made worse by a demand shock, and the policy response of 2024 to 2026 attacks both sides at once: cutting population growth to near zero while trying to double the rate of construction. The country’s average resale price rose from about $413,000 in 2015 to $811,700 at the end of 2021, according to the Parliamentary Budget Officer, before the Bank of Canada’s rate increases knocked roughly a fifth off typical values. Prices are now softer, but Canada Mortgage and Housing Corporation (CMHC) warns that new construction is slowing faster than demand, which means the affordability gains of 2025 and 2026 could reverse when population growth resumes. This article explains how the gap opened, why the Carney government chose a state developer as its flagship fix, and what the early evidence says about whether Build Canada Homes can move the national numbers. It is part of the Canadian Company Stories hub.

Why did Canadian house prices double in under a decade?

Prices doubled because a decade of cheap credit and strong population growth met a planning system that could not add homes quickly, especially in Toronto and Vancouver. The Parliamentary Budget Officer traced the national average price from about $413,000 in 2015 to $565,800 at the end of 2019 and $811,700 by the end of 2021, a 97% rise in six years.

The first phase, from 2015 to 2019, was driven mostly by low interest rates and foreign and domestic investor demand concentrated in two metropolitan markets. The second, from 2020 to early 2022, was a pandemic-era surge: the Bank of Canada cut its policy rate to 0.25%, households accumulated savings, and buyers paid up for space. By late 2021 the PBO estimated that prices in Hamilton, Toronto, Halifax and Ottawa were more than 50% above what local household borrowing capacity could support.

The crucial point is that supply never caught up. Even at the peak of the boom, Canada was completing roughly 220,000 to 260,000 homes a year, while population growth accelerated to more than one million people in 2023 as the federal government loosened rules on international students and temporary foreign workers. CMHC estimated in 2023 that Canada needed 3.5 million additional homes by 2030 on top of what it would normally build. That number became the organising statistic of the political debate.

The correction that followed has been real but partial. The Bank of Canada’s May 2026 Financial Stability Report put the typical home price roughly 20% below its 2022 peak and about 5% lower over the previous 12 months, with Ontario and British Columbia posting the largest declines. The Canadian Real Estate Association’s September 2026 data showed a national average sale price of $666,538, down 1.6% year over year, and its home price index 3.4% lower than a year earlier. Prices have come off, but they have not returned to 2019 ratios of price to income.

What does CMHC say the supply gap actually looks like in 2026?

CMHC’s Fall 2026 Housing Supply Report, published on 10 September 2026, says Canada would need to start 417,000 to 469,000 homes a year to bring affordability back to 2019 levels by 2036, against a business-as-usual pace of about 231,000. The gap of 187,000 to 238,000 homes a year is described as “broadly unchanged” from the July 2025 estimate.

The report’s deputy chief economist, Aled ab Iorwerth, framed the problem bluntly: slower population growth has improved affordability somewhat, but new construction is now slowing faster than demand. CMHC’s February 2026 Housing Market Outlook forecast starts falling from an estimated 259,000 in 2025 to 247,000 in 2026 and 223,000 in 2027, with the national pace staying below its ten-year average through 2028. Actual starts in the first five months of 2026 were running 3% ahead of 2025 at 93,644 units, but the composition had shifted heavily toward rental apartments.

The regional picture explains why national averages mislead. Toronto’s gap narrowed because prices fell, but ownership construction there is “exceptionally weak”: only 156 condominium units were started in the first half of 2026, against an average of about 7,000 a year over the previous decade. Vancouver’s condo starts fell 40% in the same period to their lowest since 2011, while purpose-built rentals climbed to about 60% of starts from under 20% a decade earlier. Montreal’s and Ottawa’s gaps grew. Calgary’s gap narrowed significantly on record construction, and Edmonton was the only large market with no gap at all.

Across the big markets, purpose-built rentals now make up roughly two-thirds of apartment starts. That is useful for renters but it does not rebuild the ownership ladder, and CMHC’s central warning is that Canada could underbuild during this soft patch and fall further behind when demand returns.

How did the immigration reversal change the demand side?

The 2026–2028 Immigration Levels Plan, tabled with Budget 2025 in November 2025, holds permanent admissions at 380,000 a year but slashes temporary arrivals from 673,650 in 2025 to 385,000 in 2026 and 370,000 in each of 2027 and 2028. New study permits fall from more than 300,000 in 2025 to 155,000 in 2026. The stated target is to bring temporary residents below 5% of the population, from about 7.5% in 2024.

The effect on headline population was immediate. Statistics Canada estimated the population at 41,472,081 on 1 January 2026, down 103,504 from 1 October 2025, the first back-to-back quarterly decline on record. Non-permanent residents fell from 3,149,131 in October 2024 to 2,676,441 in January 2026. A further decline of 55,025 followed in the first quarter of 2026, driven by a 117,879 drop in non-permanent residents; permanent immigrant arrivals in that quarter were 20.2% lower than a year earlier, and deaths slightly exceeded births.

For housing, the demand shock cuts both ways. Asking rents have been falling for two years: Rentals.ca and Urbanation put the national average at $2,034 in September 2026, down 4.2% year over year and 9.2% below the May 2024 peak. Toronto and Vancouver rents hit five-year lows. That is a genuine affordability gain for tenants. But it also removes the rent growth that underwrote the purpose-built rental boom of 2023 to 2025, and it coincides with condo presale demand collapsing, so developers are shelving projects just as the government wants them to accelerate.

The Bank of Canada’s September 2026 decision statement noted only a modest rebound in housing activity after several weak quarters. Its surveys released on 19 October 2026 showed business sentiment weakening again after Canada–US trade talks broke down and new tariffs were imposed, which matters because construction employment and materials costs are both sensitive to the trade dispute.

What is Build Canada Homes and how is it structured?

Build Canada Homes (BCH) is a federal agency announced by Prime Minister Mark Carney on 14 September 2025 in Nepean, Ontario, capitalised with an initial $13 billion and given the power to approve construction on public land and to fund projects at the early, riskiest stage of development. Ana Bailão, a former Toronto deputy mayor who chaired the city’s planning and housing committee, was named chief executive.

The agency inherited the Canada Lands Company portfolio, which the Prime Minister’s Office described as 88 federal properties totalling 463 hectares, roughly the area of downtown Ottawa. Its mandate has three parts: build supportive and transitional housing with provinces, territories and Indigenous governments (with $1 billion earmarked for that purpose); expand deeply affordable and community housing; and partner with private developers on middle-income homes. A national submission portal opened in late November 2025 and, by January 2026, BCH said it had received proposals from every province and territory.

The “Direct Build” model is the agency’s distinguishing feature. Rather than only lending to non-profits, BCH acts as the developer on federal sites and issues requests for qualifications to builders. Its investment policy framework prioritises what it calls modern methods of construction: factory-built modular units, panelised systems and mass timber. The government’s stated targets are build times up to 50% faster, costs up to 20% lower and emissions 20% lower than conventional site-built housing.

Critics, including Conservative leader Pierre Poilievre, argued that the agency adds a layer of bureaucracy when the faster lever is forcing municipalities to cut permitting times and fees. The Pembina Institute welcomed the modular focus, citing potential cost savings of 20% to 25%, but said the commitments on operating affordability and climate resilience would need to follow. Both criticisms point at the same risk: a state developer can only shift national numbers if it changes how the private industry builds, not just what the federal government builds itself.

Where are the first Build Canada Homes projects and how far along are they?

The first wave is six “Direct Build” sites on federal land totalling about 4,000 homes, with the agency saying the model can scale to 45,000 units over time; requests for qualifications were issued in late 2025 and construction on the first homes was expected to begin during 2026. The sites were chosen for land already in federal hands, which removes the acquisition and rezoning stages that typically add years to a project.

The largest is Heron in Ottawa, an 18-acre site planned for about 1,100 homes, backed by a $400 million partnership with the City of Ottawa under which the city reduces development charges, permit fees and property taxes. Pointe-de-Longueuil, on the St Lawrence waterfront opposite Montreal, is planned at 1,055 homes. Arbo, at Downsview in Toronto, is planned at 540 homes with at least 40% affordable, and sits inside a $283 million infrastructure investment the government says will eventually support 63,000 homes across the wider district. Shannon Park in Dartmouth, Nova Scotia, has 630 mixed-market units in its first phase, supported by a $300 million federal–provincial agreement. Naawi-Oodena in Winnipeg and the Village at Griesbach in Edmonton together account for 675 units, developed with Treaty One First Nations and Canada Lands Company.

Bailão said in January 2026 that the agency had moved “from concept to action” in its first 100 days, and BCH reported a pipeline of thousands of further units intended to break ground in 2026 through partnerships rather than direct ownership. A separate agreement with the Nunavut Housing Corporation covers more than 700 public and supportive units. On the demand-aggregation side, the Prime Minister’s launch highlighted Nepean builder Caivan, whose modular output was planned to rise from six homes a day to 38 a day by the end of 2025, as the kind of factory the agency wants to fill with orders.

Measured against the national gap, 4,000 homes is small: Canada starts roughly that many in a week. The agency’s own logic is that its value lies in de-risking the early stage, demonstrating that factory-built mid-rise housing can be delivered at scale, and creating enough standing demand that prefab manufacturers invest in capacity. Whether it can do that before private starts fall further is the central test of 2027.

How do development charges and sales taxes inflate the cost of a new home?

Government-imposed charges can account for a fifth or more of the price of a new home in the Greater Toronto Area, which is why the 2026 federal–Ontario deal targeted them directly. CMHC analysis cited by the governments found development charges alone made up 8% to 16% of a new condominium’s price in parts of Ontario and up to 9% of the price of a detached house in Toronto, before land-transfer taxes, HST and parkland levies.

On 30 March 2026 Carney and Ontario Premier Doug Ford announced a package the governments said could cut taxes and fees on a new Ontario home by up to $200,000. The full 13% HST is removed on new homes valued up to $1 million (a saving of up to $130,000), with the maximum $130,000 rebate preserved up to $1.5 million and phasing down to $24,000 at $1.85 million and above. It applies to agreements signed between 1 April 2026 and 31 March 2027, and for pre-construction purchases construction must start before 31 March 2027 and reach substantial completion by the end of 2029. The federal legislation received royal assent on 18 June 2026. Ontario estimated roughly $2.2 billion of tax relief and 8,000 additional starts.

The second leg is $8.8 billion over ten years of cost-matched federal and provincial money for housing-enabling infrastructure, the first partnership under Ottawa’s Build Communities Strong Fund. The funding is designed to let municipalities covering about 80% of Ontario’s population cut development charges by up to 50% for three years without blowing holes in their capital budgets, since the charges nominally pay for the pipes, roads and transit that growth requires.

This builds on measures already in place: the 2025 federal GST elimination for first-time buyers of new homes, the December 2024 rise in the insured-mortgage price cap from $1 million to $1.5 million, and 30-year insured amortisations for first-time buyers and buyers of new builds. The structure of Canadian mortgages means these financing changes feed directly into what buyers can qualify for.

Can modular and prefab construction really double output?

Factory-built housing can shorten schedules and smooth labour demand, but Canada’s prefab industry is small, so the government’s plan depends on using public orders to make it bigger. Build Canada Homes has committed to bulk procurement and long-term financing specifically to give manufacturers the order books they need to invest in plants, with Buy Canadian rules steering demand to domestic lumber and component suppliers.

The economics of modular are well understood. Moving framing, insulation and finishing into a factory reduces weather delays (BCH explicitly cites building through the winter), cuts site labour and improves quality control. The government’s targets of 50% faster and 20% cheaper are at the optimistic end of international experience, and Pembina’s estimate of 20% to 25% cost savings assumes stable volumes. The catch is that modular plants need continuous demand to run profitably, and Canada’s boom-bust housing cycle has historically starved them of it.

That is why the Ontario and Ottawa deals matter as much as the agency itself. Lower development charges and HST relief change the margin on private projects; the agency’s direct orders and the Canada Land Bank change the certainty of demand for factories. Together they are a bet that Canada can move a meaningful share of mid-rise and low-rise construction off-site within a decade, as Sweden and Japan have done.

The honest counter-argument is capacity in the wider sector. Residential construction employment, the skilled-trades pipeline and the availability of serviced land all constrain how fast starts can rise, regardless of method. CMHC’s own forecast that starts fall through 2027 reflects a private market that is pulling back faster than public programmes can scale up, a dynamic visible in the collapse of Toronto’s condo pipeline.

How does Canada’s approach compare with other countries?

Canada is unusual among rich countries in combining a sharp, deliberate cut to population growth with a new state developer, rather than relying on planning reform alone. Australia, which faces a similar mix of high immigration and constrained supply, set a National Housing Accord target of 1.2 million homes over five years but has stayed with grants and planning incentives rather than direct federal building; readers can compare the two models in the Australian Company Stories hub.

The United Kingdom’s 1.5 million-home target relies on mandatory local housing targets and planning reform, with a smaller public developer role through Homes England. Canada’s Build Canada Homes is closer to the post-war Central Mortgage and Housing Corporation model of the 1940s and 1950s, when the federal government financed and sometimes built veterans’ housing at scale. The decision to revive that approach reflects a political judgment that the private sector will not build affordable housing at the volumes required on its own economics.

Where Canada’s approach is weaker is in the municipal layer. Provinces control planning law, municipalities control zoning and permits, and the federal government has only money and land. The Housing Accelerator Fund of 2023 tried to buy zoning reform city by city; the 2026 Ontario deal tries to buy fee reductions province by province. Neither replaces the provincial legislation that would be needed to make four-storey, multi-unit buildings legal by default across Canadian cities.

Finally, Canada’s exposure to interest rates is unusually direct. Because most mortgages reprice within five years, the Bank of Canada’s path, which it has held at 2.25% since October 2025, transmits quickly into both demand and the financing cost of new projects. Policy that lowers fees helps at the margin; policy that lowers borrowing costs moves the whole market.

What can founders and investors learn from Canada’s housing crisis?

The first lesson is that affordability is a flow problem: a decade of under-building cannot be fixed by two years of lower prices, and the market’s own correction mechanism, falling starts, makes the long-term shortage worse. Entrepreneurs in construction technology, modular manufacturing and development software are operating in a market where the federal government has explicitly committed to being a long-term anchor customer, which is rare.

The second is to read policy sequencing carefully. The 2026 fee and tax cuts are time-limited and front-loaded, so projects that can reach a signed agreement and a construction start before March 2027 enjoy a cost advantage that later projects will not. Investors who understand the renewal of these programmes, or their expiry, will outperform those who extrapolate current margins.

The third is that demographic policy is now a housing variable. Canada’s decision to let its population shrink for two quarters was an unprecedented demand-side intervention and it shows up in rents within months. Any business whose revenue depends on household formation, from apartment landlords to telecoms and grocers, needs to model immigration targets as a core input rather than a background assumption.

The fourth is about the limits of state capacity. Build Canada Homes is well funded and has land, but its 4,000-home first wave is tiny against a 200,000-home annual gap. Its real leverage is catalytic: proving a delivery model, standardising modular specifications and crowding in private capital. Founders who build the tooling, financing and manufacturing capacity that the agency needs are positioned to grow with it; those who wait for the agency to solve the problem alone will wait a long time.
