Objective The objective of this study was to describe Ontario primary care teams’ experiences with collaboration during the COVID-19 pandemic. Descriptive qualitative methods using focus groups conducted virtually for data collection.Setting Primary care teams located in Ontario, Canada.Participants Our study conducted 11 focus groups with 10 primary care teams, with a total of 48 participants reflecting a diverse range of interprofessional healthcare providers and administrators working in primary care.Results Three themes were identified using thematic analysis: (1) prepandemic team functioning facilitated adaptation, (2) new processes of team interactions and collaboration, and (3) team as a foundation of support.Conclusions Results revealed the importance of collaboration for provider well-being, and the challenges of providing collaborative team-based primary care in the pandemic context. Caution against converting primary care collaboration to predominantly virtual modalities postpandemic is recommended. Further research on team functioning during the COVID-19 pandemic in other healthcare organisations will offer additional insight regarding how primary care teams can work collaboratively in a postpandemic environment.
