Posting and Training Requirements

  • Issued: September 2007
  • Content last reviewed: December 2013

The Employment Standards Act, 2000, the Occupational Health and Safety Act, and the Workplace Safety and Insurance Act specify exact posting requirements.

Posters sold by private companies DO NOT COMPLY with the requirements of these acts.

The Ministry of Labour does not provide recommendations for specific training providers. You may wish to consult one of the health and safety associations (HSAs) designated under the Occupational Health and Safety Act (OHSA) to address your requirements.

If you have been contacted by a private company selling occupational health and safety posters, call 1-877-202-0008; employment standards related posters, call 1-800-531-5551.

The Ontario government is committed to protecting workers' rights, and their health and safety in the workplace. To ensure that workers are aware of their rights, employers are required, by law, to post certain documents. Some employers may also be required to conduct an annual review of their Workplace Hazardous Material Information System operations.

What workplaces are affected?

The Employment Standards Act, 2000 (ESA), Occupational Health and Safety Act (OHSA) and Workplace Safety and Insurance Act (WSIA) apply to most workplaces in Ontario. Learn more about what workplaces are not covered:


The provincial Workplace Hazardous Materials Information System (WHMIS) regulation under the OHSA does not apply to federally regulated workplaces such as banks, post offices and airports. Instead, certain sections of the Canada Labour Code and the Canada Occupational Health and Safety Regulations implement WHMIS in these workplaces. For more information about how WHMIS is enforced see the WHMIS guide.

What has to be posted in the workplace?

Posters sold by private companies DO NOT COMPLY with the requirements of the Employment Standards Act, 2000 (ESA) or the Occupational Health and Safety Act (OHSA) or the Workplace Safety and Insurance Act (WSIA).

Mandatory Poster: “Health & Safety at Work: Prevention Starts Here”

As of October 1, 2012, 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 to 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

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.

Joint Health and Safety Committees

In workplaces where the employer is required to establish a joint health and safety committee, the employer must also post the names and work locations of the committee members in a conspicuous place.

Under a regulation of the Workplace Safety and Insurance Act (WSIA), employers are required to prominently display the "In Case of Injury" Poster (Form 82) in their workplace.

This poster is provided free of charge to employers directly by the WSIB. Employers can get the poster online or by calling the WSIB at 416-344-1016 or 1-800-663-6639.

What about training?

The Ministry of Labour does not provide recommendations for specific training providers.

You may wish to consult one of the sector-specific health and safety associations (HSAs) designated by the Workplace Safety and Insurance Board (WSIB).

What is the Workplace Hazardous Materials Information System?

The Workplace Hazardous Materials Information System (WHMIS) is a Canada-wide system designed to give employers and workers information about hazardous materials used in the workplace. The provinces and territories have incorporated the national standards into their occupational health and safety legislation and regulations, and are responsible for enforcement.

Under WHMIS, employers in workplaces with hazardous materials, are required to identify those materials, ensure that proper data sheets on the materials are readily available and containers are properly labelled, and to make sure that employees are properly trained in handling and use of the materials.

Ontario's Occupational Health and Safety Act and the WHMIS regulation under the act set out requirements. The act and regulation are enforced by Health Canada designated provincial Ministry of Labour inspectors at provincially regulated workplaces. For federally regulated workplaces such as banks, post offices and airports, inspectors of Human Resources and Social Development Canada will enforce the WHMIS requirements.

Learn more about WHMIS and find out how it is enforced by the Ministry of Labour.

What about WHMIS training and review?

Training in the WHMIS is not required every year. However, certain employers are required to conduct an annual review to determine whether worker re-training is required.  Re-training may be required if new materials have been introduced into the workplace, or if workplace conditions have changed or new information on a hazardous material is available.


The review must be done in consultation with the joint health and safety committee (if the workplace has one), or with the health and safety representative.  These reviews are designed to highlight the need for training at the appropriate time. There is no prescribed "schedule" for such training.
