Erin O'Toole begins a new political life today as the leader of the federal Conservative Party of Canada.
O'Toole emerged the victor of the party's leadership race after three rounds, with 57 per cent of the vote.
It was a resounding win over his rival Peter MacKay, who won 43 per cent.
The result came in the wee hours of Monday, as machines tasked with slicing envelopes malfunctioned and several thousand ballots had to be replicated by hand under the close eye of scrutineers throughout Sunday evening.
Nearly 270,000 party members were eligible to vote in the race, and upwards of 175,000 ultimately cast a ballot.
O'Toole's victory over MacKay will be a blow to some progressives, who had hoped by choosing the former longtime cabinet minister the party could finally move past some of the social conservative issues that weighed it down in the last election.
The Ontario MP for the riding of DurhamĀ is now is racing to get a team in place before Parliament returns next month.
He will have to make swift choices on who will be in his inner circle, including campaign director, new party staffers, and aides on Parliament Hill.
O'Toole replaces Andrew Scheer as party leader.
