Kathleen Wynne’s ascension to the head of the Ontario Liberal party in January, 2013 automatically made her the province’s newest premier. Although the Liberals’ status as governing party remained unchanged, her victory necessitated the planning and execution of a transfer of power from old party leadership to new. Scholarly studies of transition in Canada and Ontario have generally focused on instances where one party takes power from another. This paper examines the Wynne transition and traces how its intra-party characteristics shaped its features and evolution. It is based on research conducted between February and May 2013 and primarily reflects 15 not-for‐attribution interviews with public servants and political figures.
