OTTAWA — Government House Leader Karina Gould is planning to launch her campaign to become the next leader of the Liberal Party of Canada this week, according to a source close to Gould. 

Gould, who was first elected when the party came to power back in 2015, would be the youngest candidate in the race and the only millennial. Other expected contenders include former Bank of Canada and Bank governor Mark Carney, former finance minister Chrystia Freeland and former B.C. premier Christy Clark, who was still mulling a final decision.
