Canada election 2015: Where the leaders are Tuesday

Canada's federal political leaders are starting to converge in the Greater Toronto Area ahead of the first leaders' debate of the campaign in Toronto this week.

Conservative Party Leader Stephen Harper is expected to remain in the area Tuesday following a Monday night rally in Ajax, on the outskirts of Toronto. He is expected to make one of his most costly policy announcements of the campaign, a tax measure said to target millions of families.

Liberal Leader Justin Trudeau will be on the other side of the GTA, starting his day early at the Mississauga office of an event-planning company that does political rallies and campaign launches. The website of the company, Bespoke Events, shows it has designed a number of federal and provincial Liberal Party events in the past.

After a down day, NDP Leader Tom Mulcair will be at a restaurant in Montreal's Ville-Marie–Le Sud-Ouest–Île-des-Soeurs riding on Tuesday.

Green Party Leader Elizabeth May is spending Tuesday travelling from her Victoria, B.C.-area riding to Toronto.

All four leaders will be in Toronto Thursday for the leaders' debate hosted by Maclean's. Bloc Québécois Leader Gilles Duceppe was not invited to take part.
