You should identify the industry that your startup company would operate in by using a standard industry classification code such as NAICS.
What is NAICS?
NAICS Canada 2017
You should first look up the NAICS Canada industry classification code, which is used mainly in Statistics Canada databases and publications. You can browse NAICS by sector.
As some Business 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.
