OTTAWA — Prime Minister Justin Trudeau said his Liberal government will look at how it can improve vetting for high-level appointments after the unprecedented resignation of the governor general over allegations of a toxic work environment at Rideau Hall. "We will continue to look at the best way to select people for viceregal appointments," Trudeau told a news conference Friday outside his residence at Rideau Cottage. "It's an important role for Canadians and we will look at how we can improve it." Julie Payette announced her resignation from the role on Thursday, about a week after the government received the damning findings of an independent investigation into allegations of harassment and other workplace issues at Rideau Hall.
