NDP Leader Jack Layton says he has received "no indication" from the federal government that any of his suggestions have been included in the upcoming budget, ideas that were a condition of his party's support.

Layton said Sunday he hasn't heard from Prime Minister Stephen Harper since the two sat down several weeks ago to discuss the NDP's key demands for the budget.

Layton told CTV's Question Period that Harper has not said whether any of his ideas have made it into the budget's final draft, which could kill his party's support for the budget and kick-start an election campaign.

"I don't want to support this particular government. I do want to get things done," Layton said.

"However, the fact that we've really had no indication from the government that they're doing anything significant, you've got to assume that that budget document's probably been sent off to some printer somewhere already being printed. So, the prime minister has either made his decisions, or he's about to make them, and he essentially has the choice to make here about whether we end up in an election or whether we have parties working together to get results."

Layton has been calling for budget provisions that would boost CPP and GIS payments for seniors, increase funding to get more doctors and nurses into family medicine and end federal taxes on home heating fuel.

"We've called for these steps…they are reasonable, they are practical, and we want the government to follow through on it," Layton said Sunday. "But we're not hearing much of a sign that they will."

Finance Minister Jim Flaherty has not committed to any of Layton's ideas, and has dismissed some of them as too expensive. However, Flaherty told CTV's Power Play recently that the opposition parties "will find that there are some measures in there that they would like."

Layton said despite having hip surgery little more than a week ago, he is ready to hit the campaign trail.

The NDP leader said he is following a physiotherapy regimen and is working the phones "and using these modern technologies that are available to us in order to get the message out and preparing for a campaign if we have to have one."

On Saturday, announcements by three Tory MPs that they will not seek re-election when Canadians next head to the polls ramped up speculation that Harper is clearing the decks and making way for new nominees in those ridings, signaling he is expecting his government to fall.

Treasury Board President Stockwell Day, Transport Minister Chuck Strahl and MP John Cummins all announced their intentions not to run.

"I think it says that the Harper administration has said to their MPs, ‘we're going into an election so if you're not running again you'd better announce it now,' otherwise there's really no other explanation for it, that I can see," Layton said.

However, Day said Sunday that while the government believes the opposition parties "might be trying to force an election," Harper did not pressure his MPs about whether or not they were committed to running.

"Absolutely no pressure from the prime minister at all," Day told Question Period. "As matter of fact he told me he was surprised, as clearly we enjoy our relationship together, it's a very good one, and he was surprised and disappointed but he respects the decision me and my wife have made."
