The North American Industry Classification System (NAICS) is an industry classification sytems developed by the statistical agencies of Canada, Mexico and the United States. NAICS is based on production-oriented principles, to ensure that industrial data, classified to NAICS, are suitable for the analysis of production-related issues such as industrial performance. NAICS Canada 2012 updates NAICS Canada 2007. The new version was implemented in 2013 to coincide with the integration of Statistics Canada's business surveys into a generalized operational model.
