If you already know who you’re going to vote for in the 2019 federal election, advance polls opened Friday across the country until Thanksgiving Monday.

More than 3.6 million eligible voters cast their ballots in advance polls in the 42nd federal election in 2015 – a 71-per-cent increase from the 2011 election.

Because of that popularity, Elections Canada has added more advance stations, to be kept open longer – from 9 a.m. to 9 p.m. local time.

Eligible voters can find their advance polling station on their voter information card, on the Elections Canada website, or by calling 1-800-463-6868.

Residents in both Sylvan Lake and Eckville can cast their votes in the advanced polls at the Sylvan Lake Community Centre.

Now that all 338 election writs have been signed, they get stamped with the Great Seal of Canada by the Registrar General of Canada. We went behind-the-scenes to check it out! The seal takes 48 hours to set. It bears the effigy of Her Majesty Queen Elizabeth II sitting on the Coronation Chair in Westminster Abbey. When it’s dry, the writs are sent to the returning officers who keep them in a secure location for the duration of the election period.
