Three federal leaders are set to visit the GTA on Tuesday but it will have no effect on the millions of Canadians who have already voted.

Elections Canada estimates that 2.4 million Canadians have already cast a ballot in the federal election, a 16 per cent increase over the 2,077,000 votes recorded over the three days of advance polls in the 2011 federal general election.

About 767,000 people voted on Sunday, which was the third day of advance polls, Elections Canada said.

Monday was the fourth and final day of advance polls for this election.

However, Canadians can still vote at one of 400 Elections Canada offices until 6 p.m. on Tuesday.

After that, eager voters will have to wait until Oct. 19.

In terms of what identification you need to cast your ballot, you have three options:

Driver’s licence or provincial ID with your photo, name and current address

Bring two pieces of ID, and one must have your current address (examples include bank statements, credit card, utility bill or student ID)

If you don’t have ID with your current address, you can take an oath. But you will still need two pieces of ID with your name, and you have to bring someone in your polling division who can vouch for your address.
