Scheer tried to draw connections Tuesday among the China-Canada dispute, the Meng case and a controversy that engulfed Trudeau's government earlier this year. A stinging report in August by federal ethics commissioner Mario Dion concluded that Trudeau violated the Conflict of Interest Act by improperly pressuring former attorney general Jody Wilson-Raybould to stop a criminal prosecution of SNC-Lavalin, a Quebec engineering and construction giant, on corruption charges. "I believe that Trudeau really did weaken our position with China as it relates to the SNC-Lavalin scandal," Scheer said at a restaurant in Mississauga.
