This research-in-progress paper examines the implementation of open science (OS) in Canada by federal science-based departments and agencies (SBDAs), following the release of the Roadmap for Open Science (ROS) in February 2020. The paper presents initial findings of a study that explores how SBDAs have engaged in open access (OA) before the ROS came into force in January 2022, the approaches and rationales SBDAs adopt to meet the ROS requirements in their respective OS action plans. The paper employs bibliometric analysis to contextualize the findings of the content analysis on SBDA OS action plans. The results are examined by ROS recommendations that directly affect SBDAs, including consultations with federal scientists, OA publication, FAIR data, and research assessment. The paper provides valuable insights into how the government understands and implements OS activities in Canada and how it intends to address obstacles impeding access to federal research.
