The housing affordability fight
Ottawa, provinces and cities are all moving, but the supply gap is measured in millions.
Summary
CMHC estimates Canada needs 3.5 million additional homes by 2030 to restore affordability. Federal, provincial and municipal governments are deploying different levers with different assumptions about what's binding.
The situation
Housing affordability sits at its worst level in 40 years by most measures. CMHC's 2023 "Restoring Affordability" report put the supply shortfall at 3.5 million homes by 2030 on top of baseline construction. Housing starts in 2025 ran below the 240,000 annual pace needed, let alone the 500,000+ that would close the gap. The federal Housing Accelerator Fund and Build Canada Homes initiative are disbursing funds tied to municipal zoning reform.
Background
Canadian housing costs diverged sharply from incomes beginning around 2015, accelerated through the pandemic-era rate cuts, and partly corrected after Bank of Canada hikes in 2022–24. Population growth — driven by record immigration and non-permanent residents — exceeded long-run trends. Municipal zoning in most of Canada restricts multi-unit housing to a small share of residential land, a structural feature that pre-dates the current crisis by decades.
Positions across the spectrum
From the Left
Progressive housing voices (e.g. Canadian Centre for Policy Alternatives, Generation Squeeze, ACORN) emphasize non-market housing at scale: federal co-op funding, public-sector builders, rent control, protection of existing affordable stock from financialization. The NDP has pushed for a national acquisition fund to purchase at-risk buildings. The left-of-centre frame: the market cannot solve this alone; supply must be deliberately affordable, not assumed to be.
From the Centre
Centrist analysts (Smart Prosperity, Centre for Urban Research and Planning, Bank of Canada research) focus on the supply-demand gap and zoning reform as the primary lever. Papers by Mike Moffatt and others emphasize "missing middle" housing — townhouses, triplexes, small apartments — blocked by zoning in most urban land. Tax treatment of real estate (principal-residence exemption, deduction asymmetries) is also flagged. Both major parties endorse much of this framing in practice.
From the Right
Right-leaning analysts (Fraser Institute, Macdonald-Laurier Institute, C.D. Howe on some files) argue the problem is almost entirely government-induced: zoning, development charges, federal population targets, and capital gains treatment on rental housing. The Canadian Taxpayers Federation and several conservative premiers argue for reducing immigration targets, cutting development charges, and eliminating federal affordability programs they view as demand-side subsidies that raise prices.
Stakeholders
- First-time buyers: median home price / median income ratio ~9x nationally, >14x in Toronto & Vancouver.
- Renters: vacancy below 2% in most major cities.
- Municipalities: development charges fund ~40% of new infrastructure; reform shifts costs.
- Homebuilders: margins compressed by labour shortages, material costs, interest rates.
- Existing homeowners: ~70% of households, sensitive to price declines.
What's next
Watch the fall 2026 federal housing update, CMHC's next supply projection, and provincial zoning pre-emption bills (BC, ON). The Bank of Canada's rate path will shape mortgage demand. Statistics Canada's updated dwelling stock estimates are expected in late 2026.
