His zigzag journey has lasted more than a year, but Michael Chong has crossed one critical finish line in his bid to rebalance power between MPs and party leaders.

The Conservative MP's bill, known as Reform Act 2014, passed the House of Commons today during a third-reading vote.

The final tally was 260 to 17, with just a handful of MP from all parties voting against it.

It has been through hours of debate, amendments, and plenty of negotiations behind the scenes with colleagues from all parties.

If passed by the Senate, it would give MPs the power to trigger leadership reviews, suspend and reinstate caucus colleagues, and to select their own caucus chairs.

Chong credits average Canadians with helping to give the bill the traction it needed — something he says the public has the power to do with any piece of legislation.

The bill would also remove the power of a party leader within the Canada Elections Act to approve election candidates.

Individual parties would determine how candidates would be approved, with the option of leaving that power with the leader.

Caucuses would choose whether to adopt proposed changes

"Change is never easy, and there is and was great institutional resistance to any change, especially changes of this sort which really strike at the heart of the balance of power in Ottawa," he said in an interview.

"I don't think this bill would have gotten this far without the support of thousands of Canadians who emailed, who wrote, who called their MPs and encouraged them to support this bill."

While the legislation lays out models for how the new powers would be implemented, Chong has agreed to amendments that would leave each caucus to choose the system they wanted after each election.

A particular caucus could even vote to leave such powers with the leader.

"I don't expect that all the rules will be adopted all at once, but in the long run, party caucuses will democratize themselves and empower themselves," Chong said.

Ever cautious when he talks about his legislative baby, Chong notes that should the bill pass, it will still need Senate approval before the House rises in June.

Chong says he has just started to meet with senators to talk over his legislation.

"This bill is a democratic reform bill, it concerns the House of Commons, and its caucuses, and how those caucuses will govern themselves and how the House of Commons will elect its members," said Chong.

"While the Senate needs to review the bill, I also hope they respect the wishes of the House in governing itself and electing its members."
