Paul Martin was campaigning in Saskatchewan Tuesday as part of a cross-country sprint to shore up Liberal support.

With polls pointing to an imminent Conservative victory with less than a week to go in the campaign, the Liberal Leader is trying to court support for his party by targeting soft Tory and NDP votes.

Speaking to a gathering of Metis supporters in Saskatoon, Martin continued his dire warnings against frontrunner Stephen Harper.

This time his message was tailor-made for the audience. Martin said Harper would abandon the Kelowna accord, an agreement reached between the government and aboriginal Canadians that aims to improve conditions in areas such as health care, education, economic development, housing and water.

He also repeated his belief that Harper would walk away from the Kyoto Accord and break "Canada's word to the world," and would shred social programs to fill the deficit the Liberals have predicted under the Tory platform.

"You ought to talk to the Inuit and go to the Arctic and see what climate change is doing," Martin said. "You understand what is happening and that Canada is suffering and that Canada in walking away from this, is betraying fundamental responsibility to the world."

Martin also described the "stark contrast" between himself and Harper.

He claimed his government would protect and value all Canadians, while Harper's would turn back the clock by abandoning progress reached under the Liberals, and would break many campaign promises.

'Six days to go'

Earlier Tuesday Martin was in Burnaby B.C., where he delivered a speech that stressed the gravity of the situation. "We've six days to go and there are real things at stake here," Martin said in his sombre speech during a campaign event.

He said the country's strong economy, medicare, personal income tax cuts and child care will all come under threat if Canadians choose not to give his party another mandate.

After repeating his attacks from previous days and his economic platform, Martin shifted direction and aimed for Jack Layton and the New Democrats.

 Martin accused Layton of attacking the Liberals incessantly during the election campaign, and all but ignoring Harper and the Tories.

"Now, elections are about choices," said Martin at the B.C. campaign stop. "And it appears Mr. Layton has made his choice: he would rather risk Stephen Harper's success than be faithful to his own party's principles."

Martin is urging NDP supporters and all "progressive voters" to vote for the Liberals on Jan. 23 -- as it appears Layton has "taken a pass" on issues such as child care and the Kyoto agreement on climate change.

Martin was touring the facilities of Xantrex Technology Inc., a solar-power company in Burnaby.

He used the tour as a backdrop to compare the Liberal environmental record to that of the Conservatives, again warning Harper will turn his back on the Kyoto agreement.

Harper has never been shy about revealing his doubts about the Kyoto accord. He recently announced that a Tory government would seek a "made-in-Canada" solution, consisting of a "Clean Air Act" to reduce the pollutants that cause smog and encourage new technologies and public transit to curb greenhouse gases.

Martin said the move would alienate Canada, "isolating us in much of the global community."

The Liberal Leader is crossing half the country in a day, keeping with a hectic pace in an effort to hold back the surging Conservative wave.

From Saskatoon he was scheduled to move on London, Ont., at each stop attempting to woo the undecided and plant seeds of doubt in soft voters' minds -- perhaps hoping wary New Democrat supporters will switch to his party during the final days, as they did in the 2004 campaign.
