Why Canada’s Supply Gap Still Defines the Next Decade of Development
Every housing conversation in this country eventually comes back to the same number, and it is not a price. It is a construction figure. Canada is building roughly 250,000 homes a year while CMHC estimates the country needs between 400,000 and 470,000 annually just to restore affordability and clear the backlog. That gap, not any single interest rate move or rebate program, is the real story coming out of RESCON’s recent Housing Summit 6.0, and it is one every developer, municipality, and investor needs to sit with.
I have spent my career watching land decisions ripple outward into communities, infrastructure, and opportunity, and what struck me most about the summit discussion is how clearly the experts separated short-term sentiment from long-term structure. Ian Lee of Carleton University put it plainly: policy reform is working, but not nearly fast enough to close a shortfall built up over a decade of population growth outpacing supply. That is not a demand problem developers can wait out. It is a production problem that requires sustained capacity, not a single good quarter.
There are genuine signs of movement. Jason Mercer of TRREB noted that the income needed to purchase a one million dollar home in the Greater Toronto Area has dropped from well above 200,000 dollars annually to roughly 140,000 to 150,000 dollars today. Ontario’s Minister of Municipal Affairs and Housing, Rob Flack, pointed to deferred development charges, streamlined site plan approvals, and a temporary HST exemption on qualifying new homes as measures already producing results, citing new single-family home sales in the GTA that tripled in July and August compared with a year earlier.

But strategy has to look beyond the headline wins. Daniel Foch’s observation about diverging regional markets deserves more attention from anyone planning large-scale projects. Cities like Calgary and Halifax are absorbing younger buyers precisely because they remain within traditional lending benchmarks of four to five times household income, while Toronto and Vancouver sit near double-digit price-to-income ratios. That divergence is not a temporary quirk. It is a signal about where population growth, labour, and capital will keep moving, and it should shape where the next generation of large projects gets located and how they get sequenced.
Development is never just about land. It is about timing, access, infrastructure, policy, demand, and the future identity of a community.
The political backdrop reinforces why this matters strategically rather than just operationally. Abacus Data’s David Coletto shared polling showing 79 percent of Canadians believe the housing system is not functioning properly, with only about one in five satisfied with any level of government’s performance on the file. In Ontario specifically, just 16 percent believe the province is moving in the right direction. That level of dissatisfaction does not fade quietly. It shapes the next round of municipal and provincial elections, and with them, the zoning, approval, and infrastructure decisions that determine whether projects break ground on schedule.
For those of us thinking in terms of feasibility studies and multi-year timelines, the takeaway from this summit is not optimism or pessimism. It is discipline. The policy tools deferred charges, streamlined approvals, targeted tax relief are proving directionally correct. But until annual completions close in on that 400,000 to 470,000 range, every development decision has to be made against the backdrop of a structural shortage that will outlast any single policy cycle.
