Building Permits Fell 17.3% in July, With Ontario Down 25.2% and Single-Family Approvals at 4,100

Where July sits in the process

Permits are the first stage. Housing starts, units under construction and completions follow. The same day StatCan released July permits, CMHC's August housing starts release covered the later stages.

The completions figure checks out, but it needs context. It is August data, while the permit data are for July. And July completions had risen 8.1%, so part of August's drop is off a high base. Meanwhile, the number of projects with permits but no shovels in the ground keeps rising.

What CMHC expects next

CMHC deputy chief economist Kevin Hughes said starts "continued to trend slightly down in August," with the decline most notable in Ontario. He added: "While the current pace of starts is elevated compared to recent years, we expect the downward trend to continue as construction activity moderates in the coming months especially towards the end of the year."

A careful reading: fewer permits at the front, fewer completions at the back and a growing backlog of approved-but-idle projects suggest a pipeline that is narrowing modestly, not seizing up. One month does not confirm a trend, and a rising backlog could turn into starts if conditions improve.

Homeowner.ca's earlier coverage of July housing starts and the approved-but-unbuilt backlog tracks how that backlog has been building.

The scarcity argument, stated carefully

The case for existing detached homes rests less on one permit report than on a pattern CMHC has described for months. In its September 10 supply-gap update, CMHC said new supply in most major markets is dominated by rentals, with ownership-oriented starts weakening, and that "a future supply crunch in the homeownership market is likely." In Toronto, it said the gap is increasingly concentrated in the ownership market, "where new construction remains exceptionally weak."

Deputy chief economist Aled ab Iorwerth put the risk this way: "new construction is slowing faster than demand. The key risk now is Canada underbuilds during this softer market and finds itself further short of housing when demand strengthens again."

For an Ontario owner of a detached house, that is the structural context. Limited new ownership supply means less competition from new builds when a resale home is listed. It does not set a price, a timeline or a guaranteed outcome. Resale values still depend on interest rates, local demand, inventory and the condition of the home itself.

Recent resale movement is covered separately in Homeowner.ca's report on home prices posting their first monthly gain since November 2024.

What the data do not support

This release does not show that detached permits collapsed. It does not prove that prices will rise, and it does not show an Ontario housing freeze. The single-family count was steady, and Ontario's big monthly drop was mostly institutional. Owners should treat July as one more data point in a slow-moving supply story, not as a signal to act on its own.

Tariff pressure that is already in place

Fewer projects in the pipeline could, over time, affect how busy trades and suppliers are. The nearer-term pressure, though, comes from trade policy. Canada imposed a provisional 25% safeguard surtax on imported wood cabinets and vanities effective July 31, 2026, for up to 200 days while the Canadian International Trade Tribunal completes an inquiry due January 15, 2027. Goods from the U.S., Mexico, Chile, Israel and certain developing countries are exempt, and the measure also covers cabinet parts such as doors, drawers and frames.

Canada's September 8 counter-tariffs on selected U.S. goods add another layer. They apply rates of 15%, 25% or 50%, with steel, aluminum and furniture in the top band and appliances in the 25% band.

What measured costs actually show

Statistics Canada's second-quarter building construction price index showed residential construction costs up 0.5% in the quarter and 2.3% from a year earlier. Metal fabrications (+2.1%) and structural steel framing (+1.8%) led the increases, while wood, plastics and composites fell 0.3%. StatCan pointed to retaliatory tariffs disrupting supply chains and "an already constrained skilled trades workforce."

That is useful calibration. The measured pressure is concentrated in metals, not lumber. Toronto was one of only three centres where residential construction costs declined in the quarter. The index measures new-build contractor prices, not renovation quotes, so it signals direction rather than what a specific kitchen will cost.
