Personal details

He was Canada's ambassador to the United States from 2016 to 2019, succeeding Gary Doer. MacNaughton presented his diplomatic papers to US President Barack Obama on March 2, 2016.

MacNaugton is credited by Canadian Business with "changing the face of public affairs in Canada" through the co-creation of the firm Public Affairs Resource Group (PARG), which in 1987 brought the services of public affairs and the polling firm Decima Research under one roof.[1]


Prior to his appointment, MacNaughton was Chairman at StrategyCorp, a Canadian public affairs and communications firm. MacNaughton also served as Canadian and North American president of Hill and Knowlton,[2] and president of Public Affairs International, which purchased Decima Research to create Public Affairs Resource Group.[3]


MacNaughton’s public sector experience includes work at both the federal and provincial levels of government. At the federal level he spent six years as a senior advisor to Don Jamieson,[4] successively Minister for the Government of Canada's Departments of Transport, Industry and Foreign Affairs.[5] A longtime Liberal Party of Canada activist, MacNaughton has been involved federally in numerous election and political campaigns.

In Ontario, he co-chaired David Peterson's successful 1987 election campaign,[6] and was a senior advisor to Dalton McGuinty in the 2003 election.[7] Following that election, from October 2003 until May 2005 MacNaughton served as principal secretary to McGuinty.[8]

In 2015, MacNaughton served as Ontario co-chair for the federal Liberal campaign that was successful in electing Justin Trudeau as Prime Minister.[9]


MacNaughton has been an outspoken advocate of government using asset sales in order to invest in new infrastructure.[10] He has also urged government to adopt a program of fundamental change in how it operates in order to more efficiently provide services.[11]
