Occupational health and safety regional offices
Find contact information for the Ministry of Labour, Training and Skills Development’s health and safety regional offices.
Health and Safety Contact Centre
Call the Health and Safety Contact Centre to:
- report incidents, work refusals, critical injuries or fatalities — if this is an emergency call 911 immediately
- report unsafe work practices
- ask about workplace health and safety topics and issues
Call the Ministry of Labour, Training and Skills Development Health and Safety Contact Centre:
Toll-free: 1-877-202-0008 TTY: 1-855-653-9260 Fax: 905-577-1316
We recommend you reach out to the Health and Safety Contact Centre rather than calling a local office.
File a workplace health and safety complaint
Learn how to file a complaint if you have a workplace health and safety or workplace harassment concern and believe your employer is not correcting the situation.
Contacting a regional office
There are several reasons for contacting a Ministry of Labour, Training and Skills Development regional office. You may be required to file written notices and reports to the office or send requests to a ministry director. You can either do this online (if online service is available) or by mailing the paperwork to the local office.
Notice of project assistance for constructors
If you are a constructor and need help completing a Notice of Project (NOP) form or need to amend information on an NOP you’ve already submitted, call the local office closest to the project and ask to speak to someone from the Construction Health and Safety Program.
