The Construction Union Wage Rate Index (including supplements) for Canada was unchanged in December compared with the previous month. The composite index was up 2.4% compared with December 2011.

Note to readers

Union wage rates are published for 16 trades in 22 metropolitan areas for both the basic rates and rates including selected supplementary payments. The indexes (2007=100) are calculated for the same metropolitan areas and are published for those where a majority of trades are covered by current collective agreements.

The wage rates and indexes are subject to a 30-month revision period after dissemination of a given month's data. This is because of the length of time that can transpire between the expiration of a collective agreement and the ratification of a new collective agreement. The wage rates and indexes are not seasonally adjusted.
