Canadian factories keep expanding in August as manufacturing PMI eases to 53.0

Canada's manufacturing sector kept growing in August, though at a slightly slower pace, according to the S&P Global Canada Manufacturing PMI released on September 1. The index eased to 53.0 from 53.5 in July, staying above the 50.0 line that separates expansion from contraction for a fifth consecutive month.

The reading came in a little better than expected and painted a picture of factories that were still adding output, orders and workers as the summer ended, even as the trade fight with the United States escalated.

The numbers versus expectations

• Headline PMI: 53.0 in August, versus a forecast of 52.7 and 53.5 in July.
• Production and new orders both increased for a fifth straight month, and output growth was the fastest since April.
• Job creation was the strongest since October 2024.
• Purchasing activity rose and input inventories edged up, partly because manufacturers bought ahead on worries about prices and product availability.
• Input cost inflation stayed elevated but eased, and output price inflation slowed from July.
• Business confidence strengthened to its highest level since late 2024.

Context: a strong summer, a harder autumn

The August survey caps a run of solid factory data. Canada's economy grew at a 3.3% annualized pace in the second quarter, and manufacturers had been benefiting from firmer domestic demand.

The same morning, Statistics Canada reported that capital expenditures in the oil and gas extraction industries totalled $11.0 billion in the second quarter of 2026, up 7.2% from the previous quarter, another sign that investment in the goods-producing side of the economy was picking up before the latest trade shock.

The risks

The weak spot is timing. The new 50% U.S. tariffs on a range of Canadian goods took effect on August 22, after much of the survey period, so August's numbers likely do not capture their full effect. Some of the strength in purchasing also reflects stockpiling ahead of expected price increases, which can flatter activity for a month or two and then reverse.

Price pressures are another concern. Even with input cost inflation easing, factories are still paying more for materials, and that is one of the channels through which tariffs and high energy prices can feed into consumer inflation.

What it means for an ordinary Canadian investor

A PMI above 50 is good news for jobs in manufacturing-heavy regions such as Ontario and Quebec, and for industrial companies listed on the TSX. But one month of data says little about how the sector will handle a full quarter of higher tariffs.

For investors, the takeaway is to avoid betting heavily on a single sector's short-term momentum. A diversified portfolio that includes industrials, but is not concentrated in exporters most exposed to U.S. tariffs, is better placed to absorb whatever the autumn data bring.
