Justin Trudeau and his Conservative rival implored supporters to stay the course and avoid vote splitting that could hand their opponent victory.Both men campaigned in the same seat-rich Toronto region on Saturday as they tried to fend off voter defections to the left-leaning New Democratic Party (NDP) and the populist People’s Party of Canada (PPC), both of which are rising in polls.The latest Sondage Leger poll conducted for the Journal de Montreal and the National Post newspapers put the Conservatives one percentage point ahead of Trudeau’s Liberals, with 33 per cent over 32 per cent.
