When Prime Minister Justin Trudeau was elected in 2015, he promised sunny ways and "a real change." Over the last nine years, there's no doubt his government has focused on fighting climate change, advancing Indigenous reconciliation and lifting some Canadians out of poverty.

By suspending Parliament and promising to resign, the prime minister bought the Liberals time. But Canada will now face Donald J. Trump with a lame duck in charge.

Justin Trudeau has announced he will step down after nine years as Canadian prime minister in the face of a mounting set of crises, but stay in office until a replacement party leader is chosen.
