Canada's highest court is set to decide today whether it will hear arguments in a trailblazing climate change lawsuit that could clarify whether governments are constitutionally required to tackle planet-warming emissions.

An Ontario appeal court ruling ordered a new hearing for a constitutional challenge of the province’s emissions reduction target.

The Ontario court hearing a climate lawsuit filed by seven youth against the provincial government has granted intervenor status to six groups, meaning Indigenous voices and those of environmental groups and parents will also be heard in court starting in September.
