Harper and Trudeau in Ontario today, Mulcair campaigns in Atlantic Canada

OTTAWA — Conservative Leader Stephen Harper heads today to a riding where the Conservatives have had a rough ride of late.

Dean Del Mastro resigned the seat in Peterborough, Ont., following his conviction for three electoral offences: overspending, failing to report a contribution he made to his own campaign, and knowingly filing a false report. He is appealing.

Del Mastro won the riding three times for the Conservatives by healthy margins, but his conviction hurt the party.

Harper starts his day in the Kitchener, Ont., area at a fair for Home Hardware franchise owners. There he's expected to tout his support for business and likely won’t resist taking a shot at Liberal Leader Justin Trudeau.

He took numerous shots at Trudeau last week for suggesting that many small businesses are used by wealthy people to avoid taxes.

The Home Hardware fair is in St. Jacobs, Ont., in the riding of Kitchener-Conestoga, held since 2006 by Harold Albrecht.

NDP Leader Tom Mulcair continues a campaign tour through Atlantic Canada with stops in Halifax, Dartmouth, N.S., and Charlottetown.

Mulcair will visit the Royal Canadian Legion branch in Dartmouth where he's expected to make an announcement in support of military veterans.

The legion hall is in what's considered safe NDP territory, the riding of Sackville-Preston-Chezzetcook, held through two previous boundary changes and since 1996 by party stalwart Peter Stoffer.

Later today Mulcair will visit a small beer maker and a lobster restaurant and market in Charlottetown, which as a riding has been Liberal territory for the past 27 years

Trudeau attends a morning town hall meeting in downtown Toronto before heading to Ottawa for an evening rally.

The morning event is in the new Spadina-York riding being hotly contested by Liberal Adam Vaughan, who represented an area riding in the last Parliament, and New Democrat Olivia Chow, who held Vaughan's riding before resigning to run for Toronto mayor last year.

Green Leader Elizabeth May has no public events.

Bloc Quebecois Leader Gilles Duceppe will make an announcement in Longueuil, Que., dealing with electric cars and then meet with the community's mayor before moving on for some mainstreeting in St-Bruno-de-Montarville.
