Wholesale Services Price Index (WSPI)
Summary of changes
Activity on this program started: 2005
With the release of second quarter 2016 data, the WSPI industry classification was updated from the 2002 North American Industry Classification System (NAICS) to NAICS 2012.
The WSPI series were also converted to 2013=100, with 2013 as the base year. The WSPI weights were updated using establishment revenues from the Business Register and the 2013 industry gross margins from the Annual Wholesale Trade Survey (record number 2445).
Two new CANSIM tables, 332-0029 (monthly) and 332-0030 (quarterly), based on 2013=100 and using new vectors, replaced CANSIM tables 332-0006 and 332-0008, which were archived with the release of second quarter 2016 data.
With this release, an additional CANSIM table (332-0008) is available that presents the WSPI as a quarterly index. The table that presents monthly data will continue to be updated with each release.
With the release of the Wholesale Services Price Index on November 17th, 2010, the index series was converted to 2008=100 as its time reference year. The index was also updated using a 2008 weighting pattern. At that time, the CANSIM table 332-0002 was terminated and replaced by table 332-0006.
