This research-in-progress paper presents the results of an exploratory analysis investigating the effect of institutional collaborations on compliance with mandated open access (OA) policies by Canadian federal science-based departments. More specifically, we explore how authors affiliated with Agriculture & Agri Food Canada (AAFC) follow the Canadian government's Roadmap for Open Science to make publications OA (gold, hybrid, green) when publishing with or without national and international collaborators. Using VOSviewer, collaboration patterns and OA compliance is visualized. Preliminary findings show that AAFC complies less with the federal OA mandate when publishing alone or with co-authors from academia and OA uptake is highest when they collaborate with other government partners.
