Psychological or psychiatric injuries at work can happen suddenly, due to a traumatic situation, or can develop over time. They can also develop in response to being injured at work or undergoing treatment for a work-related injury. To accept a claim for a psychiatric or psychological injury, there must be a confirmed psychological or psychiatric diagnosis as defined in the most current version of the Diagnostic and Statistical Manual of Mental Disorders (DSM).
WCB will presume that a confirmed psychological or psychiatric injury arose out of and occurred in the course of employment in the following circumstances, unless there is evidence to the contrary:
- A first responder (as defined in section 24.2 of the Workers' Compensation Act) has been diagnosed with post-traumatic stress disorder (PTSD) or a worsening of an existing case of PTSD (for accidents/incidents that occur on or after December 10, 2012). First responders include firefighters, police officers, peace officers (sheriffs only), and paramedics (including emergency medical responders (EMRs), primary care paramedics and advanced care paramedics).
For accidents/incidents that occur on or after April 1, 2018, correctional officers and emergency dispatchers are also covered.
Effective April 1, 2018, this presumptive coverage also includes other psychological/psychiatric conditions that develop after a confirmed exposure to a traumatic event at work. - A worker has been diagnosed with a psychological/psychiatric condition and had a confirmed exposure to a traumatic event at work (for accidents/incidents that occurred between April 1, 2018 and December 31, 2020).
For any circumstances and time frames not specified above, WCB will accept a confirmed psychological/psychiatric injury when there is a link between the psychological/psychiatric diagnosis and the work accident/incident(s) or the injury/subsequent treatment. This includes:
- A traumatic event at work; it must be confirmed that the psychological/psychiatric injury was caused, at least in part, by the traumatic event/situation at work.
- An accumulation of work stressors over time or a stressor that exists over time; it must be confirmed that the stressor(s) is the predominant cause of the psychiatric/psychological injury.
- A psychological response to being injured and/or undergoing treatment for that injury; it must be confirmed that the psychological/psychiatric injury was caused, at least in part, by the injury or treatment.
An event/incident(s) at work is considered to be traumatic when it involves direct personal experience of an event or directly witnessing an event that is sudden, frightening, shocking, specific and involves actual or threatened death or serious injury to oneself or others or threat to one’s physical integrity.
For the period of April 1, 2018 to December 31, 2020, a traumatic event can also include workload or work-related interpersonal incidents that are excessive and unusual in comparison to the pressures and tensions experienced in normal employment.
Effective January 1, 2021, interpersonal relations between a worker and coworkers, management, or customers may be traumatic when they result in behaviours that are aggressive, threatening or abusive. Excessive workload alone would not be considered traumatic but may be considered as a chronic stressor.
Review the information on file to determine if there is evidence that the worker experienced a traumatic incident at work or an accumulation of stressors over time.
Also review whether there is a confirmed psychiatric or psychological diagnosis made by a physician (including psychiatrists) or psychologist using the criteria in the most current edition of the DSM.
Contact the worker and the employer to obtain information about the traumatic incident or workplace stressors. Ask questions to get an understanding of the worker’s injuries, how they’re coping and progressing and any initial or ongoing medical treatment they have received.
If a decision to accept the claim or injury cannot be made immediately and the worker advises they are not yet receiving any treatment, offer up to five sessions of psychological counselling so they can receive support until the review is complete.
If the information is unclear or there is no confirmed DSM diagnosis, contact the worker’s physician or psychologist using the appropriate letter to obtain additional information or clarification.

When additional information is required to make a decision on acceptance or the injury, obtain an opinion from a medical consultant or psychological consultant or consider referrals for additional investigation(s) such as a Psychological Injury (PI) assessment, a Comprehensive Psychological Assessment (CPA) or an Independent Medical Examination (IME – psychiatric). A CPA may be helpful in establishing if the work stressors are the predominant cause of the psychological injury diagnosed. See the Medical testing, referrals and program support procedure for more information on making a referral.
Additional information may be needed to make the initial entitlement decision, such as interviews with other stakeholders or witness statements. The decision maker may request assistance from the Investigation unit to help gather the information they are having difficulty obtaining.
