The New Democratic Party (NDP) is going to elect a new leader.
The NDP is Canada’s official opposition party.
The leader of the NDP was Jack Layton. He passed away last August from cancer.
It will be hard to fill his shoes, because he was well respected and liked not just by members of his own party, but by Canadians across the country.
There are nine candidates vying to be leader of the NDP.
On Sunday night they held a leadership debate.
A debate is when candidates talk about the issues, and say why they think they’d make the best leader.
