Strong gains in residential investment for September

Investment in residential building construction went up 7.3% to $12.9 billion for the month of September. Growth in residential investment was driven by Ontario (+6.7%; +$325.1 million), Quebec (+9.1%; +$191.6 million), Alberta (+10.6%; +$164.6 million) and Manitoba (+33.6%; +$102.2 million).

Institutional investment drives non-residential sector

Third quarter declines due to residential sector

Across Canada, investment in building construction fell 2.8% to $54.7 billion in the third quarter, the fourth consecutive quarterly decrease. The residential sector was down 4.4% to $36.7 billion in the third quarter, while the non-residential sector rose 0.5% to $17.9 billion.

Investment in residential building construction was down by 4.4% from the second quarter to $36.7 billion in the third quarter, driven by declines in single family home investment.

This partially offset declines in Ontario (-3.1%; -$238.7 million) and British Columbia (-4.0%; -$170.7 million) in the third quarter of 2023.

Investment in non-residential construction was up 0.5% to $17.9 billion in the third quarter, the 11th consecutive quarterly increase.
