Canada's manufacturing sector slipped back into contraction in October, with the S&P Global Canada Manufacturing Purchasing Managers' Index (PMI) falling to 49.6 from 51.5 in September, according to S&P Global. It marks the first reading below the neutral 50 threshold in 2026 and the lowest since December 2025, as tariffs and geopolitical uncertainty weighed on both domestic and international demand. The reversal ends what the report described as an uninterrupted run of solid growth for the sector through 2026 so far.

Key readings at a glance

• Manufacturing PMI: 49.6, versus 51.5 in September — the first sub-50 reading of 2026 and the lowest since December 2025
• Production: first decline since March
• New orders: steepest contraction in over a year
• Export orders: fifth consecutive monthly decline, with the sharpest fall since January
• Supplier delivery times: greatest deterioration since August 2022
• Input costs: fastest increase since June 2022
• Selling prices: strongest inflation in over four years
• Employment: first net decline since March

Demand and output weaken

The weakness was evident in both production and new orders. Manufacturers highlighted disruption to trade with the United States, while delivery delays also constrained output. Backlogs declined solidly for a second consecutive month, and firms reduced employment as departing workers were not replaced. Export orders have now declined for five straight months, the longest current decline among the report's key indicators, underlining that weakness abroad has persisted longer than in any other area of the survey.

Cost pressures move the other way

The inflation picture moved in the opposite direction. Tariffs, higher steel and fuel prices, and rising freight costs pushed input cost inflation to its strongest since June 2022. Manufacturers responded with the largest increases in selling prices in more than four years. Confidence in the outlook remained historically subdued. The cost surge comes alongside supply-side strain, with supplier delivery times deteriorating by the most since August 2022 — a sign of the disruption the report flagged, alongside tariffs, as a drag on output.

Paul Smith, Economics Director at S&P Global Market Intelligence, said:

"Having enjoyed an uninterrupted run of solid growth throughout 2026 so far, Canada's manufacturing sector ran out of steam in October, recording a marginal deterioration in operating conditions overall. Against a backdrop of tariffs and ongoing supply-side disruption, firms reported concurrent drops in both output and new orders over the month. To add to the broad deterioration in operating conditions, there was also an intensification of price pressures as input costs and output charges both rose at rates not seen for over four years, with inflation underpinned by tariffs, trade disruptions from the Middle East and AI related demand pushing up product prices. Given that these price and supply drivers are unlikely to be resolved soon, underwhelming demand and elevated price pressures are set to continue for the foreseeable future. No wonder firms therefore remain subdued in their assessment of the outlook, with confidence again remaining well below trend in October."

Implications for the Bank of Canada

Commentary accompanying the report flagged an uncomfortable mix for the Bank of Canada: falling orders, declining production and job losses point to weaker activity, but rising costs and selling prices complicate the case for lower rates. The deterioration in demand would normally weigh on the Canadian dollar and put upward pressure on USDCAD, though persistent inflation could limit expectations for policy easing. A key question is whether manufacturers can continue passing higher costs to customers as demand softens. Given the survey's monthly cadence, November's reading will show whether October proves a one-month dip or a longer downturn, and S&P Global's commentary indicated the tariff and supply drivers behind the price pressures are unlikely to be resolved soon.

What the report measures

The S&P Global Canada Manufacturing Purchasing Managers' Index is a monthly, seasonally adjusted survey covering orders, output, employment, supplier delivery times and purchased inventories. Readings above 50 signal improving operating conditions, while readings below 50 indicate deterioration. Traders follow its demand and pricing signals for clues about growth, inflation and interest rates, and its monthly timing makes it one of the quicker reads on factory conditions between official data releases.
