The final weekend of the election campaign will see the leaders pushing in the ridings where they think they can tip the balance.
For the NDP, that is in Quebec and Ontario, while Bloc Québécois Leader Gilles Duceppe is sprinting through a dozen Quebec ridings where the race is close.
The NDP took 12 Ontario seats in 2006, and hopes to pick up at least four more.
But it's in Quebec where the party has big hopes. Leader Jack Layton was campaigning in Gatineau Friday night, the fifth time he has been in the riding now held by the Bloc's Richard Nadeau.
The NDP has never won a Quebec seat in a general election, but sees Gatineau as a potential breakthrough.
Conservative Leader Stephen Harper and Liberal Leader Stéphane Dion will both be in southern Ontario Saturday, although Harper will make a swing to Montreal.
Green Leader Elizabeth May is in Central Nova, where she's trying to dislodge Tory Defence Minister Peter MacKay.
