VANCOUVER (Reuters) - A month ago the prospect of Canada's charismatic Liberal prime minister, Justin Trudeau, losing power to a little-known ex-air force navigator would have been faintly ridiculous.
When Trudeau called the Sept. 20 election, he had a hefty lead in opinion polls. But with less than two weeks to go, public opinion has soured on him to such an extent that Conservative leader Erin O'Toole could end Trudeau's six years in office.
