Overview

• The Supreme Court of Canada has refused to hear Ontario's appeal, sending the youth-led climate case back to the Ontario Superior Court for a new hearing.
• The case, led by seven young plaintiffs, challenges Ontario's 2018 emissions target as violating their Charter rights to life, security, and equality.
• Ontario's revised target, set in 2018, allows for significantly higher emissions compared to the previous goal, drawing criticism for falling short of scientific consensus.
• The Ontario Court of Appeal previously ruled that climate policies must align with Charter obligations, a decision upheld by the Supreme Court's refusal to intervene.
• Legal experts suggest the outcome of the case could reshape how Canadian governments are held accountable for climate action under constitutional law.
