With the release of November 2013 data, Statistics Canada converted the Industrial Product Price Index (IPPI) and the Raw Materials Price Index (RMPI) series to 2010=100, with 2010 as the base year. These indexes have also been updated using a weighting pattern based on the 2010 production values of Canadian manufacturers.
At the same time, the classification system was converted to the North American Product Classification System (NAPCS) developed by Canada, the United States and Mexico.
What this self-congratulatory blurb doesn't mention is that Statistics Canada has replaced an IPPI that went back to 1956 with one that goes back to 2010. I can't think of any interesting question that can be answered with a price index that starts in 2010.
