TORONTO — In less than two days, the Canadian political scene has been swept by three resignations linked to accusations of sexual misconduct.

The one with the greatest political implications came early Thursday morning when the opposition leader of Canada’s most populous province resigned as the head of his party shortly before a television network aired a report in which two women accused him of sexual misconduct when they were teenagers.

The resignation of the leader, Patrick Brown, threw the Progressive Conservative Party of Ontario into disarray about five months before provincial elections that many believed he was poised to win.

Then late Thursday, Prime Minister Justin Trudeau announced that he had accepted the resignation of Kent Hehr, the minister of sport and persons with disabilities, pending an investigation into possible sexual misconduct.
