GERALD BUTTS is the vice chairman and a senior advisor at Eurasia Group. Butts has successfully led Canadian and global organizations in the public and private sectors for 20 years. As the principal secretary to Canadian Prime Minister Justin Trudeau from 2015–2019, he was responsible for providing executive direction on the development, implementation, and communication of the government’s agenda. This work included overseeing economic policy, the negotiation of the Paris Climate Accord, and the creation of Canada’s first national climate change plan, which included an economy-wide price on carbon. Butts played a major role in managing relations with the US administrations of Barack Obama and Donald Trump, as well as in the renegotiation of NAFTA. Prior to his work with the prime minister, he served as policy secretary and principal secretary to the premier of the province of Ontario, where he led the implementation of the government’s $100 billion core agenda. A successful leader in politics as well as public policy, he designed the strategies for the Liberal Party’s 2015 and 2019 national election campaigns, as well as Trudeau’s bid to win the party’s leadership in 2013. The 2015 campaign, widely recognized as one of Canada’s most innovative and successful, allowed the Liberal Party to move from third place in Parliament to form a majority government. Its gain of 148 new seats was the largest in Canadian history.
