Carney names ex-Blackrock executive as new US ambassador

December 22, 2025

Canadian Prime Minister Mark Carney has selected Mark Wiseman, a former BlackRock executive and experienced investment manager, to serve as Canada's new ambassador to the United States, replacing outgoing ambassador Kirsten Hillman. The appointment comes during a critical period as Canada navigates deteriorating relations with Washington and prepares for challenging negotiations regarding the trilateral free trade agreement. Wiseman, who currently advises financial firms Lazard and Boston Consulting Group, will join Canada's negotiating team in mid-February to advocate for Canadian economic interests.

Who is affected

Mark Wiseman (appointed as new ambassador)
Kirsten Hillman (outgoing ambassador ending her tenure)
Prime Minister Mark Carney
Canadian workers, businesses, and institutions
Conservative party leader Pierre Poilievre (critic of the appointment)
The United States and Canada (bilateral relations)
Mexico (as party to CUSMA)
Century Initiative (charitable organization co-founded by Wiseman)

What action is being taken

A scheduled review of CUSMA is underway, starting with public hearings and stakeholder consultations
Trump has imposed sector-specific tariffs on Canadian metals, lumber and automotives
Trump has imposed a sweeping 35% tariff rate on all goods

Why it matters

The appointment matters because Canada and the US are experiencing severely strained relations at a crucial juncture, with trade talks having been halted and significant tariffs imposed by the Trump administration. The review of CUSMA could determine whether the trilateral trade agreement continues or expires, which would have profound economic implications for Canadian workers, businesses, and institutions. Wiseman's extensive financial experience and contacts are being relied upon to help navigate these complex negotiations and advance Canadian interests during this period of transformation in the bilateral relationship.

What's next

The new ambassador is set to take on the role in mid-February
After public hearings and stakeholder consultations conclude, Canada, the US and Mexico could agree to renew CUSMA or let it expire
