Advance polls open this weekend for the Aug. 1 Ottawa South byelection.

The first of five advance polling stations opened in Ottawa South Saturday as the minority Liberal government try to hang on to the seat last held by former Premier Dalton McGuinty.

Ottawa South voters can now vote from 10 a.m. to 8 p.m. at the Dempsey Community Centre Saturday.

Beginning Sunday, voters will also be able to cast ballots at the riding office at 1800 Bank St., the Greenboro Community Centre, Canterbury Community Centre and Riverside Community Centre.

Voters must bring their voter registration cards and identification to vote.

5 byelections Aug. 1

The byelection day is Aug. 1 for Ottawa South and four other provincial ridings: Etobicoke-Lakeshore, London West, Scarborough-Guildwood and Windsor-Tecumseh.

The byelection for Ottawa South was called after McGuinty resigned in June after earlier stepping down as premier.

John Fraser is the Liberal candidate, and McGuinty's former point man in the constituency.

He faces challenges from Progressive Conservative Matt Young, New Democrat Bronwyn Funiciello and Green Party representative Taylor Howarth, among other candidates.
