The plaintiffs from seven provinces, the Northwest Territories and Yukon were all between the ages of 10 and 19 when the case began. They are arguing that Canada is putting young people’s health, safety and futures at risk by supporting fossil fuel development while repeatedly missing its emissions targets. They want the court to require the government to develop and carry out a climate recovery plan that protects their constitutional rights.
“This was a way to share my voice, to influence our governments without having the ability to vote,” Vipond said.
The case is reaching the trial stage after seven years of legal motions and appeals, including federal efforts to have it dismissed. Many plaintiffs were barely teenagers when they joined and have grown into adulthood waiting for their day in court.
Now, they have more to lose. Some have taken outdoor jobs, where staying inside to escape wildfire smoke can mean going unpaid. East Coast plaintiffs, who had never experienced wildfire smoke when the case began, now encounter it regularly, said Andrea Rodgers, deputy director of US strategy at Our Children’s Trust, which supports the case.
One plaintiff has since become a mother and will testify during the trial’s first week. “Now, it’s not just about protecting her rights and her future,” Rodgers said. “It’s about ensuring that her son can grow up and thrive in a healthy environment.”
A generation coming of age in a changing climate
Extreme heat and wildfire smoke have limited Vipond’s ability to bike to school and exercise outdoors. Now a third-year environmental sciences student at the University of British Columbia, she said her studies have helped her recognize changes around her — from increasingly dangerous snow conditions to pine beetles destroying an entire hillside.
“A lot of people think that climate change is like a long, slow evolution of changes,” Vipond said. “However, we’re really seeing it from year to year at this point.”
Vipond’s experience reflects a broader reality for young people coming of age as climate change dictates how they imagine and plan their lives. A study published in 2023 found that nearly two in five Canadians aged 16 to 25 said climate change made them hesitant to have children.
That concern also shows up in their politics. In July, a poll found that one in four respondents aged 18 to 34 ranked climate change and the environment among their top three issues, compared with 16 per cent of those older than 55.
The climate risks extend across their lives. At 1.5 C of warming, over half of children born in 2020 would face unprecedented lifetime heatwave exposure, compared with 16 per cent of those born in 1960, a global study projected in 2025.
Rodgers has spent 15 years representing young people in US climate cases, including Juliana v. United States. Its 21 young plaintiffs spent nearly a decade arguing that federal energy policies violated their constitutional rights. The case never reached trial after an appeals court ruled that judges lacked the power to order and oversee the climate recovery plan the plaintiffs sought. She hopes Canada will deliver what those young Americans were denied.
The Canadian trial will also test how international law informs that duty. In July 2025, the International Court of Justice affirmed that governments must protect the climate system to safeguard human rights. Rodgers said the Canadian court could use that advisory opinion to help justify an order requiring climate action, and set an example for courts in other countries.
“Canada really has a choice,” Rodgers said. “Do they want to follow in the path of the United States or forge their own path, one that protects the rights of their own children?”
Vipond joined the lawsuit out of fear for her own future. As she heads to court next week, she said she now feels responsible for speaking for other children too young to vote and generations yet to be born.
People have asked whether she and the other plaintiffs would receive money if they win. She tells them they are seeking accountability rather than a payout.
“Hope is really hard to hold on to sometimes,” Vipond said. “But we’re all fighting to keep it.”
