Canada’s building permits reversed sharply in September 2026, falling by 4.1% month-over-month after a strong 7.6% increase in August, according to data updated on 12 November 2026.
The latest figures highlight a notable loss of momentum in construction intentions. In August 2026, permits had surged 7.6% compared with July, signaling robust activity and optimism in the building sector. However, the September 2026 reading shows that this strength did not persist, with permits contracting on a month-over-month basis.
On a comparative basis, the “Actual” September result reflects the change from August to September 2026, while the “Previous” August figure captures the shift from July to August 2026. The move from solid growth to a meaningful decline suggests increased caution in the sector and may point to emerging headwinds for Canada’s construction pipeline heading into the final quarter of the year.
