Worked example: a software consultancy

Search software or open 541514. The parent chain reads 54 (Professional, scientific and technical services), 541 (Professional, scientific and technical services), 5415 (Computer systems design and related services), 54151 (same title), then 541514, "Computer systems design and related services (except video game design and development)". A company that builds games would instead land on 541515, "Video game design and development services". The U.S. code 541511 does not exist in the Canadian structure, which is why a copied U.S. code can be wrong.

How the structure works

NAICS Canada 2022 has five levels: 20 sectors (2 digits), 99 subsectors (3), 323 industry groups (4), 694 industries (5) and 923 Canadian industries (6). Manufacturing, retail trade, and transportation and warehousing use range sector codes: 31-33, 44-45 and 48-49. Typing a two-digit code such as 32 takes you to its range sector. Counts come straight from the Statistics Canada structure file, 2,059 classes in total.

Where this fits with the CRA

This page only helps you find the right Statistics Canada class; it makes no claim about any CRA-specific mapping or list. Follow the instructions on the form you are completing, and when unsure, pick the class that matches the activity producing most of your revenue.

FAQ

Is the NAICS code on a CRA registration the same as this code?

CRA asks for a NAICS code at business registration. This page lists the Statistics Canada classes so you can find yours; it does not map to any CRA-specific list.

Can I use a U.S. six-digit NAICS code in Canada?

The first five digits are shared among Canada, the U.S. and Mexico, but the sixth is national detail. Use this page for Canada and the U.S. lookup for U.S. filings.

Which version is used?

NAICS Canada 2022 Version 1.0, the current structure on Statistics Canada's site at the capture date.

What if my business does several things?

NAICS classifies by primary activity, usually the one producing the most revenue.
