"JustinTrudeau'sLiberals stood with Stephen Harper onC-51, and now they will join with him again to helpcut jobs in our tourism, agriculture and auto sectors,"Mulcairsaid in a prepared text of his speech.

The Liberals launched an attack of their own, with their party operatives handing out leaflets at the NDP town hall, which quote an Ontario New Democrat candidate questioning her own party's fiscal promises.

The NDP has pledged to balance the federal budget, even with new spending proposals on a range of measures from aboriginal education to its $15 dollar-a-day daycare plan.

SusanErskine-Fournier, running for the NDP in St.Catharines, Ont., is quoted telling a local debate Tuesday that the promise to balance the budget "is very risky."
