Workplace Mental Health

  • Issued: January 2017
  • Content last reviewed: July 2018

A psychologically healthy workplace is one that actively works to prevent harm to worker psychological health, including in negligent, reckless, or intentional ways, and promotes psychological well-being. Such workplaces enjoy better recruitment and retention of talent, improved employee engagement, enhanced productivity, higher levels of creativity and innovation, and higher profit levels.

Below are links to websites that have valuable information on mental health in the workplace.

Chronic and Traumatic Mental Stress Entitlement

In May 2017, the Workplace Safety and Insurance Act, 1997 (WSIA) was amended to provide for both chronic and traumatic mental stress entitlement. These amendments come into force on January 1, 2018.

On December 14th, Bill 177 (An Act to Implement Budget Measures, 2017), which clarifies the transitional and retroactive coverage of the expanded chronic and traumatic mental stress entitlement, received Royal Assent. The Bill amends the WSIA to require as of January 1, 2018 that:

  • Claims for mental stress entitlement pending at the WSIB and WSIAT be adjudicated by the WSIB in accordance with the expanded mental stress entitlement; and
  • Claims for mental stress entitlement arising on or after April 29, 2014 be adjudicated by the WSIB in accordance with the expanded mental stress entitlement.

Workers whose claims for mental stress entitlement were previously denied may wish to seek reconsideration of their claims by the WSIB and WSIAT.

The government acknowledges that the concerns raised by the Ontario Network of Injured Workers Group (ONIWG) and the Injured Workers Consultants (IWC) about clarifying transitional coverage for mental stress injuries in their recent application were very helpful in developing the amendments to the WSIA.
