Mendelsohn, the deputy secretary to the cabinet for results and delivery, will also become a senior adviser to the Privy Council Office, the public-service counterpart to the Prime Minister’s Office. Mendelsohn was previously a deputy minister in the Ontario government and joined the public service after the Liberals’ federal election victory in 2015, for which he helped develop the party’s platform. His responsibilities in Ottawa included shaping the prime minister’s mandate letters to cabinet ministers and the system for tracking the government’s performance against those goals. (The Logic)

Talking point: While Mendelsohn was perhaps best known for his role in “deliverology”—a policy implementation and measurement method pioneered by the U.K.’s former Labour government—he also had a significant role in Ottawa’s efforts to deal with technological change. He co-authored the government’s internal data strategy, designed to allow departments and agencies to make better use of the information they collect. He also led a team of officials seconded by some departments with responsibility for digital files—such as the heritage, foreign, public safety and innovation ministries—which offered advice on digital platforms and governance. Mendelsohn is the latest top adviser to leave Ottawa after last fall’s election, following Kate Purchase and Mike McNair, the PMO’s executive directors of communications and policy, respectively.
