​​​​​​​​We are one of the country's largest mental health research hospitals as measured by grant funding – $29M in 2019. Our researchers pursue important and innovative work investigating the causes of numerous mental illnesses and developing​ new ways to treat them and deliver better care.

Our clinicians and researchers continue to deepen our understanding of physical and mental health integration by conducting ground-breaking discoveries in a wide range of areas. They are joined in their research by graduate and post-graduate students affiliated with the University of Toronto.

Our research footprint expanded in 2021 with UHN Psychedelic Psychotherapy Research Group. It will study the promise of a new treatment paradigm that has the potential to support patients across a range of mental health disorders.

Details about our current mental health research work are listed by category below.

UHN's research in the area of medical psychiatry explores mental health care and outcomes for those with physical health issues and those undergoing surgery. Areas of specific focus include organ transplantation, bariatric surgery, cardiac surgery, delirium, stroke, medical assistance in dying and sleep. We use innovative research methods including quantitative and qualitative studies, artificial intelligence, and technology-assisted interventions. In addition, several investigators are involved in studying health care worker distress during and adaptation to COVID.
