Liberal Leader Michael Ignatieff will take the weekend to weigh the Conservatives' second economic progress report before announcing whether his party will try to trigger an election, CBC News has learned.

Liberal Leader Michael Ignatieff will spend the weekend deciding whether to trigger an election over the Conservatives' economic progress report. (Paul Chiasson/Canadian Press)The NDP and Bloc Québécois immediately denounced the progress report and indicated Thursday they would vote against Prime Minister Stephen Harper's minority Conservative government.

A spokesman for Ignatieff told CBC News the Liberal leader will use the weekend to read the report and consult with people on the party's next move before announcing his decision on Monday.

The earliest date the opposition parties could present a no-confidence motion and defeat the Tories in the House of Commons is next Friday, when MPs are slated to vote on the latest round of spending estimates in support of the government's economic recovery plan.

On Thursday, Ignatieff criticized the Tories' report for what he said was a lack of transparency in showing whether stimulus money is actually reaching Canadians.

"You have to have a PhD in economics to figure out whether [the money] has actually got out the door," he said. "Our objection to the whole government's performance is that we cannot establish whether the money is getting out."

Ignatieff also lashed out at both the NDP and Bloc for their quick criticism of the weighty 234-page progress report.

Prime Minister Stephen Harper says Canadians want politicians to work together to improve the economy instead of fighting an election campaign. (Fred Chartrand/Canadian Press)On Friday, Harper made it plain that he would blame the opposition for stalling that stimulus should they force an election.

"Nobody wants to see the coalition again, nobody wants to see us doing more political games," Harper said during a visit to Summerside, P.E.I.

"They just want to see the government and all parties working on the economy. That's what we're doing."

The prime minister said Thursday that roughly 3,000 infrastructure projects across the country are getting underway as part of the government's $22.7-billion stimulus plan.

He added that 80 per cent of the plan's funding has already been allocated.

In exchange for supporting the Conservative budget in January, the Liberals demanded quarterly reports on the state of the economy and on how federal stimulus funds were being spent.

With the economy performing poorly, the unemployment rate has gone up. In May, the national jobless rate reached an 11-year high of 8.4 per cent.

Canadian unemployment has been rising since it hit its most recent bottom of 5.8 per cent in January and February of 2008.
