A group of young people argue Ontario's weakened emission target is a violation of their Charter rights. On Thursday, the Appeal Court of Ontario declined to rule on that question, but said lower courts shouldn't have dismissed the case,

The court of appeal in Canada's most populous province ordered a new hearing on Thursday in a youth-led lawsuit claiming Ontario's climate plan violates young people's rights.

Ruling sends the case back to lower court for a new hearing and revives the possibility that Ontario's weakened emissions target may still be found unconstitutional

In a decision released Thursday, three judges from the Court of Appeal for Ontario sided with the appellants in Mathur v. Ontario that a Superior Court of Justice judge “erred” in deciding the young people’s case was a “positive rights case” in an April 2023 decision.

Province’s Court of Appeal heard arguments earlier this year brought by seven young people who say Ontario’s weakened emissions target is a violation of their constitutional rights

It's the first case to be tried in Canada that considers whether climate change has the potential to violate Charter rights.

Ontario's top court is set to release its decision in a landmark youth-led Charter challenge of the provincial government's climate change plan.
