The Bloc Québécois has helped the Conservatives pass a contentious crime bill that would eliminate early parole eligibility for non-violent offenders.

Critics of the government's tough-on-crime bills say not enough is being done to help victims and to rehabilitate offenders. The Bloc backed the Harper government's Bill C-59, which easily passed the House of Commons by a vote of 184 to 105 on Wednesday.

The Liberals and NDP opposed the bill, but the Bloc support moves the legislation to the Conservative-controlled Senate.

The bill eliminates a convict's right to apply for parole after serving one-sixth of their sentence for non-violent crimes such as fraud.

The Bloc says it has long favoured such legislation, and supported the Tory bill because of high-profile fraud cases in Quebec, including the conviction of disgraced financier Earl Jones.

Under the bill, convicted fraudsters and other non-violent criminals must now serve one-third of their sentences before seeking parole.

Liberal Leader Michael Ignatieff said his party couldn't back the bill because it does nothing to help defrauded victims get their money back.

"We think this Bloc-Conservative coalition ... is the worst abuse of Parliament I've seen in a very long time," said Ignatieff.

Ignatieff said the bill would affect only 1,500 prisoners but would add $130 million to Canada's prison tab.

The Quebec bar has advised the Liberals that the bill is unconstitutional, he said.
