Hudak, who became leader of the party in 2009, announced his resignation after congratulating Wynne on her majority government win.
He says he will stay on until a new leader can be chosen, but plans to retain his Niagara-area seat.
But Hudak couldn't resist a parting shot, saying Ontario residents deserve a government that believes in transparency and creating jobs — the primary themes he has used over the last 40 days to beat up on the Liberals.
He calls it a hard-fought campaign, one in which he says the party should be proud.
During the campaign, he simply dismissed or ignored economists who said the Conservatives had made a fundamental math error in their promise to create one million jobs over eight years.
