Two Decades of Undersupply: What CMHC’s Price Data Reveals About Canada’s Development Gap
When a national housing agency tells you prices have more than doubled in real terms over twenty years, the headline writes itself. But for those of us who think in terms of land, permits, and build timelines, the real story sits one layer down. A new CMHC report released October 20 confirms what many of us in development circles have argued for years: Canada’s affordability crisis was never a single shock. It was a slow, structural failure to build fast enough, for long enough, and it has compounded year over year.
The numbers deserve attention from anyone involved in large scale housing strategy. In 2023 and 2024, Canada added nearly five new residents for every housing unit completed. Compare that to Australia and Sweden, where the ratio was considerably tighter, and you start to see why our price trajectory diverged so sharply from peer nations. This is not a demand problem we can wish away. It is a pipeline problem, and pipelines are built one approval, one site, one project at a time.
What strikes me most is the construction rate data. New housing stock grew from roughly 1.2 per cent of existing supply in 2011 to just 1.3 per cent by 2022. That is barely a shift over eleven years, even as demand accelerated hard after 2021. Eleven of the seventeen countries CMHC examined increased their construction pace relative to existing stock faster than Canada did. We were not standing still by accident. Planning timelines, zoning constraints, and project feasibility hurdles all play a role in why supply couldn’t respond to a demand signal that was, frankly, not subtle.

The report also highlights that Canada has fewer homes per 1,000 residents than most comparable developed economies. That is a baseline infrastructure problem, not a cyclical one. Sweden and Norway absorbed comparable population growth with larger existing housing stocks already in place, which gave their markets more room to breathe. Canada entered this growth period thin, and thin markets move fast when demand arrives.
Canada’s housing challenge isn’t just that home prices rose. It’s that demand grew faster than supply for longer than in many comparable countries.
That quote, from CMHC deputy chief economist Aled ab Iorwerth, is the line every municipal planner and project sponsor should sit with. The affordability story didn’t start in Vancouver’s early 2000s runup or Toronto’s early 2010s surge by accident. It spread city to city, including into Ottawa, Montreal, and Halifax, because the underlying supply response was slow everywhere, not just in the markets that made headlines first.
CMHC is now preparing an international review of construction strategies across ten peer countries, looking at financial incentives, planning reform, construction innovation, and the use of public land. That is exactly the right next step. For developers and planners, the lesson from this report is not that Canada’s market is broken beyond repair. It is that the tools other countries used to keep supply closer to demand, faster approvals, more flexible land use, innovative build methods, are worth studying seriously and applying with urgency. The communities that act on this gap earliest will be the ones best positioned for the next growth cycle.
