Two Windsor-Essex MPs have been reacting to Mark Carney's appointment to the role of Canada's prime minister with a mixture of praise and disappointment.

To win the next election, the new prime minister must quickly prove he is Canada’s best hope of managing relations with the White House.

The former central bank chief takes over at what he has called a “time of great consequence” for Canada, with Trump attacking its sovereignty and economic security.

Carney, 59, replaces Prime Minister Justin Trudeau, who announced his resignation in January but remained in power until the Liberal Party elected a new leader. Carney is widely expected to trigger a general election in the coming days or weeks.
