A brief guide to conducting research for your assignments.

NAICS (Industry) Codes

You should identify the industry that your company operates in by using a standard industry classification code such as NAICS.

What is NAICS?

  • NAICS is the acronym for the North American Industry Classification System.
  • It was developed jointly by Canada, the US, and Mexico to describe economic activity and currently divides the economy into:
    • 20 sectors (2-digit codes)
    • 102 subsectors (3-digit codes)
    • 324 industry groups (4-digit codes)
    • 710 industries (5-digit codes)
    • 928 Canadian industries (6-digit codes).
  • NAICS codes are comparable across Canada, the US, and Mexico at the 5 digit code level. Note: unique national industries will have a 6 digit code.
  • The latest version is NAICS Canada 1.0 (release in 2022).

You should first look up the NAICS Canada code, which is used mainly in Statistics Canada databases and publications. You can search by keyword or browse by sector.




As some Business Library Databases use the US version of the NAICS manual, it is also helpful to be able to cross-reference your NAICS code there, as the numbers can be slightly different.  In addition, as the US economy is vastly larger than the Canadian, they have a more comprehensive classification system. You can use the keyword search to identify relevant codes, or browse NAICS by sector.
