Ontario Housing Supply · Updated monthly
Ontario Housing Supply Update — June 2026
Ontario started almost exactly as many homes this June as last June, while starts fell nearly 16% nationwide. Underneath that flat headline: single-detached construction down almost a fifth, and starts outside Ontario’s cities cut nearly in half.

What the data shows
CMHC released its June 2026 monthly housing starts in mid-July. June is one of only four months a year — with March, September, and December — where CMHC actually enumerates starts in centres under 10,000 population, rather than estimating between counts, so this release carries more weight than April’s or May’s. Ontario’s total starts came in essentially flat, up half a percent from a year ago on a seasonally adjusted annual basis. That headline number hides two stories moving in opposite directions: single-detached starts down almost a fifth, multi-unit up almost 6%, netting out to no real change. Nationally the picture was worse — Canada-wide starts fell nearly 16% year-over-year — so Ontario technically outperformed the rest of the country this month, but for the wrong reason: apartments carrying a province that still isn’t building the houses people are asking for.
Why conventional supply is pulling back
A province that can only hold its starts flat by leaning harder on apartments isn’t fixing its ground-related supply problem — it’s substituting for it. Single-detached starts have now fallen for three straight releases, and June’s nearly 20% year-over-year drop is the steepest yet. At today’s land, permit, financing, and trade-labour costs, a stick-built single-detached home below a certain price point doesn’t pencil out for most builders, so they keep rotating toward multi-unit, where the land economics work and the buyer is a renter, not an owner. The families who want a house with a yard are the ones absorbing that shift.
Where modular fits
Factory-built homes sidestep the cost structure pinning site-built single-detached near its floor — lower production cost, a build measured in months instead of a year-plus, and none of the weather or trade-fragmentation risk that makes conventional single-detached construction unpredictable. CMHC counts modular homes on permanent foundations inside these very starts numbers — modular isn’t a workaround to the data, it’s inside it. Every modular home delivered while conventional single-detached keeps sliding is net-new ground-related ownership supply the market isn’t otherwise producing.

Small centres and the coverage gap
June is one of the four months a year CMHC actually counts starts in centres under 10,000 population and rural areas, instead of estimating between quarters — which makes this month’s number the most reliable read all year, and it’s the steepest decline yet: starts outside Ontario’s larger centres fell nearly 48% year-over-year, deeper than April’s 33% or May’s 32%. The gap keeps widening exactly where conventional builders build least — exurban land-lease, on-reserve First Nations land, small-town and rural Ontario. Those are the places modular delivers fastest, and where the supply gap is now the widest it’s been all year.
For landowners outside major centres, our landowner partnership model puts modular communities into footprints conventional developers won't touch.
What this means for buyers and investors
For homebuyers: a flat pipeline propped up by apartments isn’t a pipeline for the home you actually want. Waiting for site-built single-detached supply to recover means waiting for a cost problem that’s now three releases deep and getting worse, not better. Modular delivers within months at price points conventional builders no longer hit. For investors: demand is structural, conventional ground-related supply keeps shrinking, and the one month a year CMHC actually counts rural and small-centre starts just confirmed that gap is the widest it’s been all year. Single-unit modular ownership and small-scale rental plays sit exactly where that gap is opening fastest.
