About PTSD

Posttraumatic Stress Disorder (PTSD) is a diagnosable, mental health disorder that may occur after exposure to psychological stressors during a specific, severe, potentially psychologically traumatic event or series of events.


PTSD has specific psychological symptoms and can affect people of any age, culture or gender.

PTSD may involve different combinations of:

  • triggers
  • flashbacks
  • sleep disturbances
  • intrusive memories
  • persistently negative thoughts
  • low mood, anger, or feeling emotionally numb
  • regular, vivid recall of the psychologically traumatic event
  • trouble remembering parts of the psychologically traumatic event
  • having difficulties feeling emotionally connected to family or close friends
  • avoiding reminders or thinking about the psychologically traumatic event

PTSD may be diagnosed if:

  • symptoms last for more than a month, and
  • symptoms cause significant distress or impairment:
    • at work or school
    • in social or family life
    • in other important areas of functioning

The diagnosis of PTSD is made if the person's condition isn't better explained by another physical or mental health disorder.

PTSD in Canada

Prevalence of PTSD symptoms in Canada

About 8% of adults have moderate to severe symptoms of PTSD. This percentage is higher among women (10%) than men (6%). It is highest among people aged 18 to 24 (14%) and lowest in people aged 65 and older (3%).

Adult Canadians diagnosed with PTSD

About 5% of adults report having a diagnosis of PTSD. Having a diagnosis of PTSD is not the same as having moderate to severe symptoms. Not everyone with moderate to severe symptoms seeks care or gets a diagnosis.

A diagnosis must be given by a healthcare professional, such as a:

  • family doctor
  • psychologist
  • psychiatrist

A healthcare professional will use information about PTSD symptoms as part of their assessment.

How the Government of Canada is helping

We are committed to addressing PTSD. In June 2018, the Government of Canada passed the Federal Framework on Post-Traumatic Stress Disorder Act. The Act recognizes that all Canadians can be at risk for PTSD and that many face higher risks because of the nature of their work.

The Act led to a National Conference on PTSD in April 2019. Experts from across the country, including people with lived experience, shared their knowledge and views. With their involvement, we developed Canada's first Federal Framework on Posttraumatic Stress Disorder.

The release of the Federal Framework on Posttraumatic Stress Disorder: Recognition, Collaboration and Support in February 2020 connects and builds on existing federal efforts. It focuses on occupation-related PTSD, but also acknowledges other populations affected by PTSD.

The Framework was developed to help:

  • improve tracking of PTSD and its economic and social costs
  • promote and share guidelines and best practices for diagnosis, treatment and management of PTSD
  • create and distribute educational materials

The Framework also laid important groundwork for coordination and collaboration across federal sectors.

The Framework is used to:

  • support knowledge creation, knowledge exchange, and collaboration across the federal government, and with partners and stakeholders
  • inform practical, evidence-based public health actions, programs, and policies
  • reduce stigma and improve recognition of the symptoms and impacts of PTSD

As mandated by the Act, the Framework will be reviewed for its effectiveness within 5 years of its publication, by 2025. The review will include a progress update on initiatives and their results.

Federal investments addressing PTSD and trauma

Throughout the COVID-19 pandemic, many frontline and essential workers experienced long hours and prolonged stress while working to keep Canadians safe and healthy.

We committed $50 million through Budget 2021 to support projects addressing PTSD and trauma for those most affected by the COVID-19 pandemic, including:

  • health care providers
  • long-term care workers
  • personal support workers
  • public safety personnel and their families

Projects funded through this investment aim to:

  • help reduce stigma
  • remove barriers to care
  • enhance trauma-informed practice
  • improve help-seeking and system navigation
  • test and implement promising approaches and adaptations for those at risk of experiencing PTSD and trauma

This investment also supports the Canadian Institute for Pandemic Health Education and Response (CIPHER), a knowledge development and exchange hub. CIPHER uses data from funded projects to help inform mental health interventions and enhance public health policy and practice.
