ONTARIO ELECTION | Horwath in St. Catharines today

Ontario's main party leaders fan out across Southern Ontario today in their quest to win the hearts and minds of voters.

NDP leader Andrea Horwath starts the day in Toronto, then heads to St. Catharines for a 1:45 stop at the GO Station on Great Western Street.

PC Leader Doug Ford is in Cambridge and Kitchener today.

Liberal Leader Kathleen Wynne is in Ottawa before heading to Whitby.

Yesterday Wynne took aim at both Horwath and Ford demanding to know how they plan to pay for their campaign promises.

Wynne zeroed in on Ford's announcement he will lower the price of gas by 10 cents a litre.
