The Supply Math That Should Worry Every City Builder in Canada
Every so often a single number reframes an entire national conversation. This week it came from the Canada Mortgage and Housing Corporation, and it is not a small one. To bring affordability back to where it stood in 2019, Canada would need to roughly double the pace of homebuilding it is currently on track to deliver. That is not a policy talking point. It is a structural gap, and structural gaps do not close themselves.
CMHC’s fall housing supply report puts the country on pace for about 231,000 completed homes a year through 2036. To meaningfully narrow the affordability gap, that number would need to climb to somewhere between 417,000 and 469,000 annually. Anyone who has spent time around land assembly, municipal approvals, or project financing knows what a gap that size actually represents. It is not a shortfall that gets solved with a single policy announcement or one favourable interest rate cycle. It is a multi-decade capacity problem, spread across labour, land, financing, and approvals all at once.
What stands out most in the report is the honesty about why the gap persists. Construction costs remain elevated. Presale financing is difficult to secure for many projects, particularly in the condominium segment, where soft market conditions are making developers understandably cautious about launching new phases. That caution is rational at the project level, but at the national level it compounds the very shortage the report is warning about. Fewer launches today mean fewer completions in the years that follow, and the supply curve keeps falling further behind demand.
This is where development strategy has to move beyond unit counts and toward sequencing. Cities and provinces that want to close this gap need to treat it as a pipeline problem, not a single target. That means addressing presale financing conditions so projects can actually break ground, coordinating approvals so timelines do not silently erode feasibility, and being honest about where infrastructure capacity, not just zoning, is the real constraint on growth. A rezoned parcel with no financeable path to construction does nothing for the numbers CMHC is describing.
A supply gap this size is not solved by ambition. It is solved by feasibility, financing, and follow-through, project by project, year after year.
For those of us who think in terms of land value, growth planning, and long-term city identity, this report is a reminder that housing targets only matter if the underlying conditions for building exist. Doubling output is not a slogan. It requires sustained coordination between capital, construction, and policy over more than a decade. The municipalities and developers who start solving the feasibility puzzle now, rather than waiting for market conditions to improve on their own, will be the ones shaping how this gap actually closes.
