Health & Safety at Work: Prevention Starts Here

Under the Occupational Health and Safety Act (OHSA), all provincially regulated workplaces must display this poster. It outlines the rights and responsibilities of workers, supervisors and employers on the job and provides a Ministry of Labour telephone number (1-877-202-0008) to report critical injuries, fatalities and work refusals and to obtain information about workplace health and safety information.

Printed colour posters are available in English and French from Service Ontario free of charge or can be downloaded in English, French and 15 other languages.

What You Should Know About The Ontario Employment Standards Act, 2000

Under the Employment Standards Act, 2000 (ESA), employers are required to display the most recent version of the Minister of Labour's poster,"What You Should Know About The Ontario Employment Standards Act", in at least one conspicuous location in the workplace.

The poster outlines employees' rights and employers' responsibilities at work. It is available online for free and can be printed on legal-size paper for posting in the workplace. ServiceOntario Publications will also provide copies of the poster, charging only for shipping and handling.

Occupational Health and Safety Act

Under the Occupational Health and Safety Act (OHSA), employers are required to post a copy of the Occupational Health and Safety Act in their workplaces. 

The act is available online for free. It is also available from ServiceOntario Publications for a cost of $8, plus HST.

Health and Safety Policy

The OHSA also requires employers to prepare and review, at least once a year, a written occupational health and safety policy, and to develop and maintain a program to implement that policy. The policy must be posted in the workplace.

The Guide to the Occupational Health and Safety Act has detailed information about how to prepare a health and safety policy.

Workplace Violence and Workplace Harassment Policies

The OHSA also requires employers to prepare and review, at least once a year, workplace violence and workplace harassment policies, and to develop and maintain programs to implement those policies. These policies must be in writing and posted in the workplace except for workplaces with five or fewer regularly employed workers, unless ordered by an inspector.

The MOL's guideline entitled Workplace Violence and Harassment: Understanding the Law includes examples of workplace violence and workplace harassment policies.
