The Canadian Workplace Exposure Database (CWED) was created with the goal to collect workplace exposure data from government agencies, researchers, and other sources and to create a large centralized database that will house both current and historical exposure measurements from workplaces across Canada. This project aims to continue identifying and acquiring additional data from regulatory bodies and other exposure data users and encourage centralized prospective data collection in the future. This database currently includes 480,000 air-sampling measurements for chemical carcinogens collected between 2004 and 2017 across eight federal, provincial and territorial jurisdictions.

The CWED was initially developed as part of CAREX Canada’s Workplace Exposure Surveillance Project, and is similar to the Occupational Safety & Health Administration’s (OSHA) Integrated Management Information System (IMIS) in the United States.

This database includes data that was abstracted from the following organizations:

Such database can allow users to generate information about workplace exposures including the following and allow a variety of important research and policy questions to be addressed:
