Housing starts are an economic indicator that reflect the number of residential housing projects that have been started over a specific length of time. These data are divided into 3 types: single-family houses, townhouses or small condos and apartment buildings with 5 or more units.
September monthly housing starts key highlights
- The trend in housing starts increased by 4.1% in September to 277,147 units.
- The trend measure is a 6-month moving average of the monthly seasonally adjusted annual rate (SAAR) of total housing starts for all areas in Canada.
- Actual housing starts were up 19% year-over-year in centres with a population of 10,000 or greater. 22,375 units were recorded in September 2025, compared to 18,806 in September 2024.
- Montréal and Toronto posted 135% and 112% year-over-year increases in actual housing starts respectively, both driven by significantly higher multi-unit starts.

September Standalone Seasonally Adjusted Annual Rate (SAAR)

About Monthly Housing Starts and Construction Data
A housing start is defined as the beginning of construction work on the building where the dwelling unit will be located. This can be described in 2 ways:
- The stage when the concrete has been poured for the whole of the footing around the structure.
- An equivalent stage where a basement will not be part of the structure.
Housing starts statistics are organized to facilitate an analysis of monthly, quarterly and year-over-year changes. Actual and seasonally-adjusted housing starts data are presented separately. Select under construction and absorption data are also included.
Housing starts, construction and absorption data are used to gain insight into the level of activity and supply conditions in the new home market.
Actual and seasonally adjusted housing starts data are presented separately by region, province, Census Metropolitan Area (CMA) and dwelling type. Select data on under construction and absorption are also included.
These monthly housing data tables reflect:
- current statistics
- new home starts
- construction activity

About the Seasonally Adjusted Annual Rate (SAAR)
The SAAR allows you to compare monthly levels to annual levels for different months of the year. It also gives you a sense of the relative strength of monthly activity.
The time of year can be a factor when collecting data. We calculate the SAAR by:
- Using a rate adjustment to remove the data’s seasonal variations.
- Multiplying the seasonally adjusted level of starts by 12 to obtain the Seasonally Adjusted Annual Rate (SAAR) of housing starts.
