The Composite 6, which was first launched in December 2008 was initially built to capture the aggregate performance of the Canadian housing market with the richest available data at that time. In 2011, we expanded the Composite 6 by five new cities and reviewed and refined the geographic territory of each city to better align with the Census Metropolitan Area definitions provided by Statistics Canada. The Composite 11 was built with this information in hand and more precisely reflects the rate of change of single-family home prices in Canada.
As a result, the last public report that will contain the Composite 6 index (C6) data will be March 13th, 2019. After this date, only Composite 11 will be made available in the public sphere. If you still require the Composite 6 data, it will be available as a commercial offering. You can contact us to discuss options to continue receiving the data.
