The intention at the time of the creation of the Market Basket Measure was that the content of the basket and its definition of disposable income would be reviewed once several years of data had been collected using the original measure. This was necessary to ensure that it continued to embody a modest, basic standard of living within the current Canadian context. Following this initial comprehensive review, it was expected that the content of the basket and its definition of disposable income would be reviewed periodically. Following the release of the fourth report based on MBM data in December 2008 covering the years from 2000 to 2006 it was determined that sufficient experience with the original measure had been obtained to undertake the first comprehensive review of the measure during 2009 and early 2010. Human Resources and Skills Development Canada (HRSDC) joined with Statistics Canada to carry out the review.
