Months of supply: the homes for sale at the end of the month, divided by that month’s sales. More supply means buyers have more choice and more time. Each board publishes its own version of the measure.
Kept from July 2026, and a month longer each time the boards publish.

Stephen’s read: what the numbers mean for buying, renewing and investing
Board figures are copied as each board publishes them, once a month. The Bank of Canada and Statistics Canada figures are read from their public data services every week.
Figures are as reported by the sources named and are shown for information only. They are not a forecast or an offer, and past movements say nothing certain about future ones. All mortgage terms are subject to lender approval.
A chart is the same for everyone. Your renewal date, your income and the home you have in mind are not. Bring them and we will work through it together.
