The 2017 Conservative Party of Canada leadership election was held on May 27, 2017. Party members chose Andrew Scheer as leader, replacing Stephen Harper, who led the Conservative Party of Canada as its leader from 2004 following the merger of the Canadian Alliance and Progressive Conservative parties. Harper led the party through five federal elections: the party increased its seat count in the House of Commons in 2004, formed two minority governments in 2006, and 2008, and then a majority government in 2011. Following the defeat of the party in the 2015 federal election on October 19, Harper tendered his resignation as party leader. In a statement, Conservative Party President Harry Walsh said he had spoken to Harper, ``and he has instructed me to reach out to the newly elected parliamentary caucus to appoint an Interim Leader and to implement the leadership selection process.
