The leaders of Ontario’s four main political parties will face off tonight.

It’s the second and final debate of the election campaign, the first held last week focusing on issues affecting Northern Ontario.

Tonight’s 90 minute forum begins at 6:30pm, and will be available on the major Canadian networks.

Progressive Conservative Leader Doug Ford, NDP Leader Andrea Horwath, Liberal Leader Steven Del Duca, and Green Party Leader Mike Schreiner will field questions from a consortium of regional broadcasters who organized the event as well as from Ontario voters.

In order to take part in tonight’s event, parties must have candidates running in “all or almost all” 124 ridings across the province and have one elected MPP sitting in the legislature.
