Around 2.4 million Canadians have voted so far in advance polls, representing a 16 per cent increase over the three advance polling days in the 2011 federal election, says Elections Canada.

The agency estimates that 850,000 voters cast ballots on Friday, 780,000 people voted on Saturday and 767,000 on Sunday, an increase of nearly 400,000 votes compared with 2011.

Monday is the final day to vote at advance polls.

Elections Canada said that the number of people who came out to vote has exceeded expectations. There were complaints about long lineups at polling stations on Friday and Saturday.

James Hale, a spokesman for Elections Canada, said there were 4,950 advance polling stations this year. He said that on Oct. 19, there will be "fast lanes" established at polling places for electors who are registered, have the requisite pieces of identification and their voter information card (with the number of their polling division on it).

"If you arrive at the polling station with everything in order, officials will stream you into this 'fast lane,'" he said.
