Ontario Mandatory Workplace Policies, Posters, Training, and Committees
Ontario businesses should pay close attention to the workplace policies and postings they must maintain, the training they must deliver, and the safety committees they must organize. Below, we have provided an overview of some of the most common requirements applicable to Ontario employers. Stay tuned for future updates covering additional provinces, including Alberta, British Columbia, and Nova Scotia.
A Required Opportunity
Employers should view these requirements as more than a “check the box” obligation. Workplace policies and training are key opportunities to communicate with employees on expectations of behaviour at the workplace and, if prepared with care, can function (among other things) as a reputational risk control. For example, a compliant workplace harassment policy will direct employees who have experienced or witnessed inappropriate conduct by a colleague on how to report their concerns, assure them their employer will take the allegations seriously and investigate, and confirm to the employee that they will not face retaliation for speaking up. When an employee turns to the workplace harassment policy, it is essential that the employer does not miss the opportunity to provide them with effective (and legally required) guidance.
Further, these policies serve as an instruction manual on how to respond to day-to-day incidents at the workplace in compliance with Ontario law and organizational procedures. Legal exposure is not limited to failing to adopt mandatory policies. Employers who lack compliant foundational frameworks in areas like accommodation, investigations, or complaints handling face increased risk under human rights and employment law regimes. Having and consistently following appropriate workplace policies and procedures can mean the difference between resolving an issue promptly and professionally versus allowing a situation to escalate into litigation, regulatory scrutiny, penalties, and unwanted attention, including in relation to wrongful dismissal, workplace harassment and violence, and human rights claims.
How Obligations Arise
The policies, postings, and training that an employer in Ontario must maintain are determined primarily by the number of individuals the business employs in the province. Various legislation imposes requirements starting with a company’s first Ontario employee and adds more and increasingly complex requirements as the headcount grows. Remote and hybrid workers are generally required to be included in the headcount. Safety-related policies, representative, and committee requirements, on the other hand, are typically determined by the number of workers at each particular workplace rather than province-wide. Below is a chart outlining some of the most common requirements applicable to employers in Ontario. The chart is limited to measures that are mandatory under applicable statutory requirements; many employers, however, choose to go beyond these baseline obligations to help ensure that their workforce operates not only in compliance with applicable law, but also at its highest potential.
Takeaways for Employers
Employers should review their policies, postings, training, and committee compliance on a regular basis (some items are required to be reviewed on specific intervals under applicable law and new requirements arise frequently). We recommend that employers undertake such a review at least annually. Accordingly, employers should consider a proactive and structured approach, as follows:
- Map the workforce by jurisdiction and headcount to identify applicable thresholds.
- Implement a review calendar, ensuring policies are revisited at required intervals (or more frequently where appropriate).
- Align policies and procedures with practice, including proper training, reporting mechanisms, and leadership accountability.
- Plan for growth and anticipate when headcount increases may trigger new obligations.
- Have employees acknowledge, in writing, that they have received and reviewed the written materials upon hire and when updates are made.
