The three main party leaders zig-zagged across the country Saturday, capitalizing on one of the few opportunities left to sway undecided voters and encourage supporters to make it out to the polls Monday for what's likely to be a tight race.

Stephen Harper

A Conservative rally in Laval, Que., drew a large and boisterous crowd that would sporadically break out chanting "Harper" and "four more years." At one point, the crowd booed when Harper warned supporters of tax credits that a Liberal government would roll back.

Harper implored his supporters to keep up their "enthusiasm" and "determination" for "just two more days," and spoke of a "new generation of Conservative MPs" from the province.

The Conservatives are looking to gain back the five Quebec seats they lost to the NDP during the 2011 election. They currently hold five seats in the province.

During his final week of campaigning, Harper warned of a real chance that the Liberals could form the government on Oct. 19.

When asked if he's at peace with his campaign -- and the future of the Tories -- Harper replied: "In the past 10 years, I believe our Conservative government has led this country forward during a difficult time to be more prosperous, more united, more proud and more secure than ever before."

Harper is making his way to the vote-rich GTA later in the day, where he's scheduled to appear at rally that will also be attended by Rob and Doug Ford, before travelling to British Columbia

Justin Trudeau

With the Liberals maintaining their lead ahead of the Conservatives and NDP, according to the latest Nanos poll for CTV News and the Globe and Mail, Trudeau encouraged his supporters in Atlantic Canada to get out to the polls on Monday.  

"We have the chance to take Canada from Stephen Harper and give it back to Canadians," Trudeau said during a campaign stop in Saint John, N.B.

"Go knock on doors, make those phone calls, get out there and talk with your neighbours and your family and your friends," Trudeau told supporters. "Do whatever you can to make sure that no vote and no voter gets left behind."

The Liberal Leader is spending the weekend campaigning in ridings held by his opponents. Following Saint John, Trudeau is scheduled to make stops in Thunder Bay, Ont., Edmonton and Winnipeg. He has events planned in B.C. on Sunday.

Tom Mulcair

Mulcair spent the morning campaigning in British Columbia, where the NDPs are currently polling at higher levels, compared to Ontario.

Speaking at a stop in Burnaby, B.C., Mulcair encouraged supporters to attend an NDP rally. "I want to show Canadians that here in B.C., it's the NDP that is organized to defeat Conservatives and on Monday we're going to get the job done."

Mulcair also warned of Liberal and Conservative corruption.

Mulcair linked the Liberal sponsorship scandal to the revelation this week that Dan Gagnier, a member of Trudeau's inner circle, offered lobbying advice on an energy project.
