From the Editors.

We usually start our Healthcare Quarterly (HQ) editorial with reflections on the current landscape in healthcare and what is top of mind for healthcare leaders. In this issue, we are instead starting with two welcomes and a fond farewell. Our first welcome is for Richard Lewanczuk as our new co-editor-in-chief alongside Anne Wojtak. Richard is the senior medical director of Health System Integration for Alberta Health Services and was previously the senior medical director of Primary Care for the same organization. He is also a professor emeritus in the Department of Medicine at the University of Alberta where he continues to co-chair the Social Determinants of Health Working Group. Our second welcome is for Ruby Brown who is a special guest editor for our theme on mental health (Brown and Wojtak 2024). Ruby has led health systems across several provinces and territories, with an unrelenting commitment to improve the state of mental health. She believes that the key to tackling the complexity of mental health and substance use lies in our ability to maintain consistent and steadfast cooperation across all segments of society. By sharing knowledge, we can gain deeper insights into national and global proceedings, which, in turn, enlighten and obligate us all to implement approaches essential for the greater well-being of Canadians. We are excited to have both of these wonderful leaders join our editorial team.
