The 2017 New Democratic Party leadership election was won by Jagmeet Singh. The election was triggered by Tom Mulcair having lost a vote on leadership review at the party's federal convention held in Edmonton, Alberta, on April 10, 2016, which resulted in a majority of delegates voting in favor of holding a new leadership election. Mulcair declined to partake in the subsequent leadership election and stated that he would remain leader until the party chose a replacement.

Jagmeet Singh Jimmy Dhaliwal is a Canadian politician who has served as the leader of the New Democratic Party (NDP) since 2017.
