Canada's election sees Donald Trump's influence. His trade war and remarks fueled nationalism. This helped the Liberal Party. Mark Carney leads polls after Justin Trudeau's exit. Pierre Poilievre faces challenges.

Canadians vote on April 28 to elect a new prime minister. The key contenders are Mark Carney (Liberal) focusing on economic reform and government action, and Pierre Poilievre (Conservative) pushing for deregulation and tougher crime policies.

The result of a modern debate is always something of a blur. But what this year's encounters underlined is that this election is primarily about both two very different candidates for prime minister and two very different ideas of what the greatest threat to the country actually is.
