The North American Industry Classification System (NAICS) is an industry classification system developed by the statistical agencies of Canada, Mexico and the United States. However, Statistics Canada has created 5 cannabis industries that are unique to NAICS Canada 2017 Version 3.0. Created against the background of the North American Free Trade Agreement, NAICS is designed to provide common definitions of the industrial structure of the three countries and a common statistical framework to facilitate the analysis of the three economies. NAICS is based on supply-side or 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 2017 Version 3.0 consists of 20 sectors, 102 subsectors, 324 industry groups, 710 industries and 928 Canadian industries, and replaces NAICS Canada 2017 Version 2.0.
