Workplace Safety and Health

Workplace Safety and Health enforces The Workplace Safety and Health Act and its associated regulations in order to protect the safety and health of workers in Manitoba.  Workplace Safety and Health’s inspection and investigation activity focuses on improving legislative compliance in order to eliminate workplace fatalities, injuries and illnesses.​​


August 7, 2015 – Effective July 31, 2015, Manitoba’s WHMIS (Workplace Hazardous Materials Information System) provisions have changed.

These amendments align Manitoba with new federal requirements incorporating the Globally Harmonized System of Classification and Labelling of Chemicals (GHS) into new WHMIS 2015 requirements.

The introduction of the GHS brings Canada’s system into alignment with the U.S. and other trade partners. Having consistent symbols and systems in place for chemicals used in the workplace helps better protect workers on the job.

Transition from former WHMIS (WHMIS 1988) to the new system (WHMIS 2015) will occur over a three-year period, ending December 2018.

In Manitoba, WHMIS 1988 requirements for Material Safety Data Sheets (MSDSs) and labels can still be applied during the transition stage provided the label information and symbols on the products match the MSDSs. Employers must train their workers for the version(s) of WHMIS they are using in their workplaces, either 1988 and/or 2015.

Workplace Safety and Health will continue to update our WHMIS 2015 page throughout the transition period to provide guidance for employers.

The amended Part 35 of the Workplace Safety and Health Regulation will be made available online and in print as soon as possible on the Workplace Safety and Health Legislation page.
