Canada election 2015: Where the leaders are Friday

For the second time in a week, Liberal Leader Justin Trudeau is bringing in one of his party's economic heavyweights to bolster his fiscal platforms in the federal election campaign.

Trudeau will campaign in Montreal today with former prime minister Paul Martin, who was by his side earlier this week when he unveiled his economic team. The Liberals are expected to name their Quebec economic team today.

The Liberal leader tried to build some momentum in southern Ontario Thursday by announcing a plan to spend $125 billion over 10 years on infrastructure to stimulate the economy. The amount to be financed by three years of "modest deficits" is double what is currently earmarked for infrastructure projects across the country.

A willingness to run deficits has placed Trudeau apart from his rivals on the issue, with both Prime Minister Stephen Harper and NDP Leader Tom Mulcair both pledging to bring in balanced budgets immediately.

Harper mocked Trudeau's plan during his campaign event in Ontario on Thursday, saying the Liberal leader "has no idea what he's talking about" when it comes to making spending promises.

Harper will remain in the Toronto area today, where he is expected extol his government's record on defending religious freedom around the world at the National Islamic Convention of Ahmadiyya Muslim Jama`at.

Like Trudeau, Mulcair will also bring his campaign to Montreal this morning to seek votes in a riding considered a Liberal stronghold Notre-Dame-de-Grace-Westmount.

The incumbent in that riding is high-profile Liberal and former astronaut Marc Garneau.

Bloc Quebecois Leader Gilles Duceppe will make three campaign stops today in Saguenay, Que., while Green party Leader Elizabeth May is expected to take the day off from the campaign trail.
