To make sure workers are informed about their rights and responsibilities, inform workers of potential hazards, and provide access to internal and external health and safety resources, most workplaces in Ontario are required to distribute or display posters and other information.
What Are Employers Required to Post?
While posting requirements vary depending on an organization’s size, industry, and the nature of the work being performed, the most common requirements include:
Employment Standards Act (ESA) Requirements
1. Employment Standards in Ontario Poster
Helps employees and employers understand their rights and obligations under the ESA. Must be provided to workers in print, email, or digital format, and in the employee’s preferred language if available.

Workplaces with 5 or more regularly employed workers are required to prepare, maintain, and post health and safety, workplace violence, and workplace harassment policies every year.
Workplace Safety and Insurance Act (WSIA) Requirements
7. In Case of Injury Poster (1234) (Form 82)
Outlines the steps workers and employers need to take if there is an injury at work. Must be displayed prominently in English and the majority language of the workplace.
8. No Smoking/No Vaping Signs
Under the Smoke-Free Ontario Act, “No Smoking,” “No Vaping,” or dual signs must be posted at all building entrances, exits, and washrooms.
Additional Posting Requirements
- Ministry of Labour Inspection Reports & Orders – If issued, must be posted in the workplace.
- Designated Substance Exposure Information – Workplaces handling designated substances must display monitoring results and exposure levels.
Avoid Non-Compliant Posters
Posters sold by private companies do not meet Ontario’s legal requirements. Ensure all postings come from official sources such as the Ministry of Labour, WSIB, or ServiceOntario.
