Operational Policy Manual (OPM) and Employer Classification Manual (ECM)
Our OPM policies and ECM policies are online, accessible and free. The directory and search functions make navigation easy, while quick links give you related policies for your reference.

Our new classification guide for businesses
In preparation for the implementation of our new premium rate-setting model, a new Employer Classification Manual (ECM) has been developed. Our new classification structure will come into effect on January 1, 2020.

Our new classification structure is adapted from the North American Industry Classification System (NAICS) and includes additional WSIB-specific classification codes. The new classification guide contains the descriptions of classification codes we will use to classify the business activities of Ontario businesses, as well as the coverage status for each of these classification codes. You can also use the guide to search for a specific NAICS code, industry, or business activity.
