The House of Commons calendar still reads Wednesday, June 13, as Prime Minister Stephen Harper, Industry Minister Christian Paradis, left, and Government House Leader Peter Van Loan are recognized as they vote on amendments to the budget Bill C-38 in the House of Commons on Thursday.

OTTAWA — It took nearly 24 hours of continuous voting, but the government's sweeping budget-implementation bill will head for a final vote after the Conservatives quashed more than 800 proposed amendments from opposition parties.

Those amendments were paired down into nearly 160 consecutive votes that ended just before midnight Friday, sending the budget implementation bill to a final vote in the Commons on Monday.

C-38 would raise the eligibility age for Old Age Security, reform the employment-insurance system, overhaul environmental-protection and fisheries laws, and expedite natural-resource development approvals, along with hundreds of other proposed changes.

Each vote ended with the opposition losing its battle with the government, but the NDPand Liberals have vowed that they won't let the memory of Bill C-38 fade quickly.

The NDP pointed out that the sweeping piece of legislation, which takes up 425 pages of text, raised concerns from provincial premiers and former Conservative cabinet ministers.

Tory backbenchers were also leery of the omnibus piece of legislation, including David Wilks, who aired his concerns last month with his B.C. constituents in a video posted to YouTube.

"We gave Conservative MPs like David Wilks . . . 159 opportunities to stand up for their principles and their constituents," Liberal House leader Marc Garneau said.

The bill is the first of two budget-implementation acts that the government introduces annually. The second bill will be brought into the Commons in the fall, and the NDPsignalled Thursday it may resort to the same procedural tactics should the government introduce another omnibus bill.

The vote itself was not without some lighter moments.

Members of Parliament camped out in the House of Commons all day and night Thursday.

Many votes saw MPs joking and palling around, some took place in total silence and others played out over a background of heckling, as MPs voted on proposed changes to the bill that could affect Canadians for decades to come.

It must still go through the Senate, where the Conservative majority all but assures passage, before becoming law.
