Prime Minister Mark Carney made an announcement on Monday appointing business executive Mark Wiseman as Canada’s ambassador to the U.S. Wiseman, a close associate of the prime minister with significant experience in leading major pension funds, will assume his new role on February 15, 2026, taking over from Kirsten Hillman.
Wiseman’s appointment comes at a critical juncture as Canada navigates strained relations with the U.S. following President Donald Trump’s trade disputes. With upcoming talks on the Canada-U.S.-Mexico Agreement (CUSMA) review scheduled for January, Wiseman will play a key role in addressing issues such as tariffs on Canadian steel, aluminum, autos, and lumber imposed by the U.S.
Prime Minister Carney expressed confidence in Wiseman’s ability to advance Canadian interests and foster opportunities for both countries. Wiseman’s expertise will be instrumental in the CUSMA renewal negotiations, particularly in addressing demands set forth by the U.S. trade representative, including potential changes to supply management and cultural protection laws.
Despite concerns raised in Quebec regarding Wiseman’s past remarks on supply management, Ontario’s representative to the U.S., David Paterson, welcomed his appointment, citing Wiseman’s diverse sectoral experience and close ties to the prime minister as valuable assets in the negotiation process.
While some apprehensions persist, especially in Quebec, about Wiseman’s stance on supply management, Carney has reiterated the government’s commitment to safeguarding this system. Wiseman’s focus will primarily be on trade negotiations with the U.S., with his diplomatic skills and financial acumen positioned to navigate the complexities of dealing with the Trump administration.
In preparation for the challenging negotiations ahead, Wiseman’s track record as a skilled dealmaker and his rapport with Carney are seen as essential for effectively representing Canadian interests. As Canada enters a critical phase of trade talks with the U.S., Wiseman’s appointment signals a strategic move to bolster Canada’s position and strengthen ties with its southern neighbor.
