The federal trial, La Rose v. His Majesty the King, has commenced in Vancouver. Fifteen young Canadians, aged 17 to 25, are suing the federal government, alleging that the Canadian Net-Zero Emissions Accountability Act and the 2030 Emissions Reduction Plan violate their constitutional rights to life, liberty, and security of the person under Section 7 of the Canadian Charter of Rights and Freedoms.

The plaintiffs argue that current government actions fail to protect them from escalating threats such as wildfires, extreme heat, and flooding. During proceedings, plaintiffs provided testimony regarding personal harms, including trauma from wildfire evacuations in Yellowknife and the impact of climate change on food security and traditional practices for First Nations communities. One plaintiff, Sadie Vipond, testified about the mental health toll and anxiety resulting from extreme weather events, such as the 2013 Calgary floods.

Expert witnesses have provided technical testimony regarding Canada’s climate obligations. Professor Kirsten Zickfeld of Simon Fraser University stated that Canada has ‘exceeded its fair share’ of its carbon budget. Additionally, Stanford University professor Mark Jacobson testified that a complete transition to renewable energy in Canada by 2050 is ‘technically and economically feasible,’ despite potential social and political obstacles. The government maintains that climate policy is a matter for elected officials rather than the courts. The trial is expected to conclude by February 2027.
