Although it is not generally done, it is useful to compare the history of the evolution of universal health coverage (UHC) in Canada and Sweden. The majority of citizens in both countries have shared, and continue to share, a commitment to a strong form of single-tier universality in the design of their respective UHC systems. In the postwar era, they also share a remarkably similar timeline in the emergence and entrenchment of single-tier UHC, despite the political and social differences between the two countries. At the same time, UHC was initially designed, implemented, and managed by social democratic governments that held power for long periods of time, creating a path dependency for single-tier Medicare that was difficult for future governments of different ideological persuasions to alter.
