Unlocking Canada’s Housing Affordability: A Blueprint for Doubling Home Construction

Canada’s housing market has become a significant source of concern for many citizens, with escalating prices and a shrinking supply making homeownership an increasingly distant dream for a large segment of the population. The Canada Mortgage and Housing Corporation (CMHC), a national authority on housing, has recently unveiled critical estimates suggesting that a return to the more balanced housing affordability levels last seen in 2019 is indeed within reach. However, this ambitious goal hinges on a monumental undertaking: a comprehensive overhaul of the nation’s homebuilding sector. The insights from CMHC’s latest report underscore the urgency and the scale of the challenge, painting a clear picture of what it will take to stabilize and improve Canada’s housing landscape.

The Ambitious Target: Doubling Canada’s Homebuilding Pace

According to CMHC’s comprehensive analysis, Canada must dramatically accelerate its housing construction to bridge the current supply-demand gap. The corporation projects that an impressive figure of between 430,000 and 480,000 new housing units will be required annually over the next decade. This target represents an approximate doubling of the nation’s current pace of residential construction, a rate that has historically struggled to keep up with robust population growth and increasing household formation.

Aled ab Iorwerth, Deputy Chief Economist for CMHC, highlighted the monumental nature of this task while emphasizing its attainability. “Doubling the pace of housing construction in Canada is achievable, but not without a significantly larger and modernized workforce, more private investment, less regulation, fewer delays, and lower development costs,” Iorwerth stated. He further stressed the importance of technological advancement and productivity gains, adding, “It will also require significant innovation in construction technology and growth in labour productivity.” These points collectively paint a picture of a sector ripe for transformation, demanding not just more building, but smarter, faster, and more efficient construction practices.

The CMHC’s projections resonate with findings from other financial institutions. A recent report by TD Bank suggested that approximately 400,000 new units per year could be sufficient to alleviate the housing shortage. However, TD economist Rishi Sondhi echoed CMHC’s concerns, warning that challenges such as construction sector productivity and an aging, retiring workforce represent “structural challenges that will need to be overcome.” Both reports converge on the consensus that without substantial systemic changes, Canada’s housing crisis will only deepen, making the goal of restored affordability increasingly elusive.

Unpacking the Hurdles: What It Takes to Build More Homes

Achieving such ambitious construction targets is not merely a matter of political will; it necessitates a multi-faceted approach addressing long-standing systemic issues within the Canadian construction industry and broader regulatory environment.

A Modernized and Expanded Workforce

The current labor force in the construction sector faces significant pressures, including an aging demographic and a persistent shortage of skilled tradespeople. To meet the CMHC’s targets, Canada will need to invest heavily in training and recruitment initiatives to attract and retain a diverse pool of talent. This includes fostering apprenticeship programs, promoting careers in trades to younger generations, and perhaps even leveraging immigration to fill critical skill gaps. A modernized workforce also implies embracing new construction techniques and technologies that can boost efficiency and safety, thereby maximizing output per worker.

Increased Private Investment and Innovative Financing

Private capital is crucial for funding the massive scale of development required. Governments can play a role by creating attractive investment environments through incentives, tax breaks, and reduced bureaucratic hurdles. Exploring innovative financing models, such as public-private partnerships or land value capture mechanisms, could also unlock significant funds for infrastructure and affordable housing projects. Encouraging investment in purpose-built rentals, a segment often overlooked, is particularly important for addressing affordability challenges for a broader demographic.

Streamlining Regulation and Reducing Delays

The current regulatory landscape, often characterized by complex zoning bylaws, lengthy permitting processes, and varying municipal standards, frequently contributes to project delays and increased costs. A coordinated effort across all levels of government is essential to streamline these processes, adopt more standardized building codes, and implement “fast-tracking” systems for qualifying projects. Revisiting restrictive zoning laws that prioritize single-family homes over denser, more affordable housing options is also a critical step in enabling greater supply in established urban areas.

Lowering Development Costs

High development charges, land costs, and material expenses are significant barriers to building more affordable homes. Governments could explore measures to reduce these costs, such as providing public land for development, capping development fees for certain types of housing, or investing in infrastructure that reduces the burden on developers. Addressing supply chain vulnerabilities for construction materials could also help stabilize costs and ensure timely project completion.

Innovation in Construction Technology and Productivity Growth

To truly double construction output, the industry must embrace technological innovation. This includes adopting modular and prefabricated construction methods, which can significantly reduce build times and on-site labor requirements, enhance quality control, and lower costs. Automation, advanced robotics, and building information modeling (BIM) can further improve efficiency, reduce waste, and accelerate project delivery. Fostering a culture of innovation and providing support for R&D in the construction sector will be vital for long-term productivity gains.

Regional Disparities: Where the Shortages Hit Hardest

While the housing crisis is a national concern, its severity and manifestations vary significantly across Canada’s provinces and major metropolitan areas. Understanding these regional nuances is key to crafting targeted and effective solutions.

Provincial Hotbeds of Housing Unaffordability

CMHC’s analysis points to Ontario, Nova Scotia, and British Columbia as the provinces grappling with the most significant housing supply gaps. These regions experienced some of the fastest-rising housing costs during and after the pandemic, driven by a combination of strong interprovincial migration, robust economic growth in certain sectors, and pre-existing supply constraints. In Ontario and British Columbia, particularly, high population density and limited developable land in desirable urban centers exacerbate the problem, leading to intense competition for available housing. Nova Scotia, while traditionally more affordable, has seen an unprecedented surge in demand, pushing prices beyond historical norms.

Aled ab Iorwerth reiterated the goal behind these regional estimates: “By estimating housing supply gaps across Canada, our goal is to ensure policymakers from all orders of government, as well as the private sector, understand the scale of the challenge. Systemic changes are essential if we are to double the pace of homebuilding in Canada.” This underscores the need for localized strategies integrated within a national framework.

Supply Gaps by City: A Closer Look

• Montréal: Among Canada’s large Census Metropolitan Areas (CMAs), Montréal faces the most substantial housing supply gap. Despite its historical reputation for affordability compared to Toronto or Vancouver, current trends indicate that “housing affordability challenges will become much more acute if housing supply is not significantly increased,” according to CMHC. This growing pressure is fueled by increasing population and evolving lifestyle preferences, requiring a substantial boost in new construction across various housing types to preserve its relative affordability advantage.
• Toronto: As Canada’s largest city and a major economic hub, Toronto’s affordability crisis is well-documented. Estimates suggest a daunting 70-per-cent increase in homebuilding over the next decade is necessary to meaningfully improve its dire affordability issues. Despite a recent uptick in rental construction, the region continues to suffer from a severe shortage of homeownership options that are accessible to local incomes, trapping many in the rental market or pushing them to the city’s periphery. Land scarcity, high development costs, and complex municipal approvals further compound these challenges.
• Vancouver: Consistently ranked among the world’s least affordable cities, Vancouver requires an estimated 7,000 additional homes annually above its “business-as-usual” construction scenario – a 29 per cent increase. While the region saw over 33,000 housing starts in 2023, the report emphasizes that “This continued level of construction would help the region’s longstanding affordability issues for both homeowners and renters.” The unique geographical constraints, robust demand, and high land values in Vancouver make addressing its housing supply particularly challenging, demanding creative solutions and denser development.
• Calgary: Calgary presents an interesting case. Having experienced record levels of home construction for three consecutive years, it still faces significant needs. The city is estimated to require 45 per cent more new homes annually than today’s levels. This demand surge is largely a result of strong interprovincial migration and post-pandemic economic recovery, which has driven up housing costs. The report notes that this increased supply “would help counter post-pandemic affordability challenges for both the homeownership and rental markets,” indicating that even robust construction can struggle to keep pace with rapid demand shifts.
• Ottawa-Gatineau: This capital region holds the unenviable position of having the second-largest housing supply gap among Canada’s large CMAs. Despite a commendable increase in homebuilding from 2021 through 2023, new supply has simply not kept pace with the accelerated housing demand experienced since the pandemic. The influx of federal government employees, a growing tech sector, and lifestyle shifts have created a persistent imbalance, making it harder for residents to find affordable housing options.
• Edmonton: A notable outlier in the CMHC’s report, Edmonton is projected to require no additional supply beyond what is currently forecasted. The analysis suggests that sufficient market housing is expected to be built in the region to maintain affordability by 2035. This more favorable outlook is likely due to factors such as comparatively lower land costs, a more balanced demand-supply dynamic, and potentially more streamlined development processes than its larger counterparts. Edmonton’s situation offers valuable lessons for other cities on how proactive planning and efficient execution can contribute to long-term housing stability.

The Path Forward: Collaborative Solutions and Policy Implications

The CMHC’s report serves as a powerful call to action, emphasizing that the housing affordability crisis is a shared responsibility demanding unprecedented collaboration. Achieving the ambitious target of doubling home construction will necessitate coordinated efforts from all levels of government—federal, provincial, and municipal—alongside robust engagement from the private sector and civil society organizations.

Federal initiatives could include increased funding for affordable housing programs, investment in construction technology and skills training, and incentives for municipalities to expedite development approvals. Provincial governments have a crucial role in reforming land-use planning, standardizing building codes, and investing in crucial infrastructure that supports new housing developments. Municipalities, at the frontline of development, must embrace progressive zoning reforms, streamline permit processes, and foster community engagement to support denser, more diverse housing options.

The private sector, in turn, needs to be innovative and adaptable, exploring new construction methods, investing in workforce development, and collaborating with governments to bring projects to fruition more efficiently. Innovative financing models and partnerships between non-profit organizations and private developers can also unlock new avenues for delivering affordable housing.

Ultimately, the systemic changes advocated by Aled ab Iorwerth are not just about building more houses; they are about building a more sustainable, equitable, and prosperous future for all Canadians. By tackling the root causes of supply shortages and embracing a forward-looking approach, Canada has the potential to transform its housing landscape, moving from a state of crisis to one where housing affordability is once again a cornerstone of national well-being.

Conclusion: A Unified Vision for a More Affordable Canada

Canada stands at a critical juncture in its housing trajectory. The CMHC’s latest estimates illuminate a clear path back to housing affordability, albeit one that requires extraordinary effort and a paradigm shift in how the nation approaches homebuilding. Doubling construction output, modernizing the workforce, simplifying regulations, and fostering innovation are not merely suggestions but imperatives. While the challenges are formidable, the potential rewards—a stable housing market, reduced social inequality, and enhanced economic growth—are well worth the concerted national effort. The vision for a more affordable Canada is within reach, provided all stakeholders commit to the systemic changes necessary to turn ambition into reality.
