UOJM is pleased to have collaborated with the Department of Psychiatry Research Day committee to put together this special issue. The University of Ottawa Department of Psychiatry virtually hosted its annual Research Day on November 17, 2021. This year’s theme was Climate Change and Mental Health. The online event welcomed 168 registered individuals. The abstracts found in these conference proceedings highlight the quality and diversity of ongoing research within the Department of Psychiatry. We’d like to thank all members of the planning committees, the UOJM team, and all students involved for their hard work in contributing to and finalizing this special issue.
