Canada's political leaders began their final weekend dashes on Saturday before voters decide on Monday whether to grant Conservative Prime Minister Stephen Harper a rare fourth consecutive mandate after a long and hard-fought campaign.

Harper attended a Toronto rally that was organized in part by controversial former Toronto Mayor Rob Ford, who admitted to smoking crack during his time in office. Now a city councilor, Ford's small-government, anti-tax message has kept him popular in parts of Toronto's vote-rich suburbs.

Harper was introduced by Ford's brother, Doug, who has said he would consider a Conservative leadership run if Harper left.
