Widespread decline within residential construction
In January, investment in residential building construction decreased $504.3 million to $16.4 billion. Declines were recorded in both the single-family (-3.4%) and the multi-unit (-2.7%) components.
Investment in single-family home construction decreased $255.2 million to $7.3 billion in January. This decrease partly stems from the $119.7 million decline in the value of single-family building permits in December. The decline in January was largely attributable to Ontario (-$164.4 million) and British Columbia (-$91.0 million). Gains in four provinces (+$47.4 million) moderated the overall decline.
Meanwhile, investment in multi-unit construction was down $249.1 million to $9.1 billion in January. Quebec (-$220.6 million) led the decrease, supported by broad declines across seven other provinces and one territory.
