Industry Classification Codes

Directories and databases often arrange company information by industry classification codes (hierarchical numbers assigned to companies engaged in the same activity). Two classification codes are currently in use in Canada - the newer North American Industry Classification system (NAICS) and the older Standard Industrial Classification system (SIC). In most cases, you will have to identify both codes for an industry.
