The controversial legislation that imposes a new contract for thousands of Ontario teachers will soon become law.

The minority Liberals and Progressive Conservatives teamed up to pass the legislation on Tuesday by a vote of 82 to 15.

The controversial bill has angered unions and a national civil liberties group -- who say it violates constitutional rights.

They have vowed to fight the bill all the way to the Supreme Court of Canada.

The legislation is retroactive to September 1st, so it would claw back any pay hikes or benefits with the rollover of old contracts once it becomes law.

It's based on a deal the province reached with English Catholic and francophone teachers, including three unpaid days off in the second year and cutting sick days in half to 10 a year.

The Liberals argued the legislation is needed to help eliminate Ontario's 15 dollar billion deficit.
