Canada’s 45th general election is officially underway. In five weeks voters will head to the polls to decide who will be the next prime minister. Liberal Leader Mark Carney is calling for a “strong, positive mandate” to take on U.S. President Donald Trump. Conservative Leader Pierre Poilievre says a Tory government will be “respectful and firm” when standing up to Trump. The NDP, meanwhile, kicked off a campaign that is likely to be critical for Jagmeet Singh’s party and the Bloc Quebecois are also facing unexpected headwinds.
