Stephen Harper starts Tuesday, Day 32 of the election campaign, in Quebec's Eastern Townships near Sherbrooke.
He's going to Asbestos, Que., home to the Jeffrey Mine, one of the world's largest asbestos mines.
Asbestos is a silicate mineral used in building construction that can cause cancer if it's inhaled. Most forms have been banned in the European Union. The Conservatives, however, support the industry and are in town to trumpet their backing for the maligned mineral.
It's located in the Bloc-held riding of Richmond-Arthabaska. The Tories lost last time by a wide margin - more than 8,800 votes.
This however is Mr. Harper's second visit to the riding this election. The Conservatives are running Jean-Philippe Bachand, brother of form Progressive Conservative MP André Bachand.
Later Mr. Harper flies to Ottawa for a rally at the airport with Ottawa-area candidates.
Then he flies to Kitchener to overnight.
Liberal Leader Michael Ignatieff will make a public-safety-related message in front of a Vancouver police station on Tuesday, then flies to a rally in Winnipeg.
Jack Layton hits the major media markets in the two biggest provinces, spending the day doing TV and radio interviews in Montreal before heading to Toronto for what's billed as a "multimedia" town hall event.
The NDP Leader's morning appears to be an attempt to keep the party's wave of support rolling in Quebec by appealing to voters over the airwaves, rather than hitting local events in ridings where the party, according to the polls, is suddenly competitive. In Montreal, Mr. Layton will do an interview on the Quebec channel "V," and then one with popular radio host Paul Arcand. After that he flies to Toronto for a 6 p.m. town-hall-style event at the University of Toronto's Father Madden Hall.
Bloc Québécois Leader Gilles Duceppe spends the day in Montreal, making the rounds of media outlets before watching the Canadiens-Bruins playoff game.
