VANCOUVER, B.C. — A Federal Court judge ruled that the Canadian government will not go on trial under his watch for its contributions to climate change, with youth plaintiffs in La Rose v. Her Majesty the Queen notified today that they must first take their request to a higher court.

In spite of acknowledging that “the negative impact of climate change to the Plaintiffs and all Canadians is significant, both now and looking forward into the future,” Justice Michael D. Manson of the Federal Court of Canada granted the government’s motion to strike the plaintiffs’ claim.

Justice Manson acknowledged in his decision that the Public Trust Doctrine is a justiciable issue and “clearly a legal question, which the Courts can resolve.” In addition, he clarified that his “comments above are not to be taken as suggesting that the Defendants should not be responsible or unaccountable in addressing climate change. The Defendants acknowledge that climate change posses [sic] a serious societal issue of our times, requiring responsiveness from all stakeholders.” However, he still ruled that the courts were unable to advance the case on the basis of justiciability, “…no matter how critical climate change is and will be to Canadians’ health and well-being, which is acknowledged.”

Plaintiffs’ lead lawyer Joe Arvay, Q.C. said that despite the decision, “we maintain confidence in the strength of our claim and intend to appeal.”

Sophia, one of the youth plaintiffs, called the decision “a slap in the face and a big wake-up call for all Canadian and Indigenous youth. Canada has tried to silence our voice in court and block our calls for climate justice. We won’t be dissuaded. I, along with my co-plaintiffs, will continue to fight for the Charter rights of all Canadian and Indigenous youth to hold Canada accountable.”

Mikaeel, an 11-year-old plaintiff, noted that “as someone who can’t vote, realizing that my only protection is not something that I can rely on is disappointing.”

In 2019, the 15 plaintiffs – who range in age from 10 to 19 – filed suit alleging that the Canadian government causes, contributes to and allows dangerous levels of greenhouse gas emissions, and therefore is responsible for climate related harms they are experiencing.

The La Rose case asks the court to declare that Canada is interfering with the youth’s Charter rights to life, liberty, security of the person and equality, and calls on the court to order the government to prepare and implement a plan to reduce its greenhouse gas emissions in a manner consistent with the best available science.

“I am incredibly disheartened by the court’s ruling,” said youth plaintiff Lauren, 16. “As a young Canadian whose rights are being violated, having the court grant the government’s motion to strike is very upsetting, and I feel that my rights to a safe and healthy future are not being taken seriously by those in power.”

Albert, 18, commented, “It would be a shame that the Constitution be of no help when it comes to this existential crisis. If courts can’t rule in favour of justice, then who can? I hope the Court of Appeals will agree with me. Whatever happens, we will not make it possible for them to keep threatening our ability to live. There is just no other option. Ce serait une aberration que la Constitution soit jugée inutile pour garantir nos droits et nous protéger face à cette crise existentielle. Si les tribunaux ne peuvent pas intervenir en faveur de la justice, qui le peut? J’espère que le ou la juge de la cour d’appel sera de mon avis. Peu importe, nous ne pouvons pas laisser le gouvernement continuer à jouer avec nos vies. Ce n’est tout simplement pas une option.

The plaintiffs, who come from seven provinces and one territory, are already being harmed by the government’s contributions to dangerous climate change by being exposed to deadly wildfire smoke, sea level rise, extreme temperatures, more frequent hurricanes, and other devastating personal impacts.

In his ruling, Justice Manson said his concern was not that the plaintiffs are asking that the court “consider a network of Canada’s actions and inactions related to climate change, but with the undue breadth and diffuse nature of that network, which puts Canada’s overall policy choices at issue.”

Justice Manson added that, although the case would be “based on scientific data and the assessment of that data,” he believed the questions raised in the case “are so political that the Courts are incapable or unsuited to deal with them.”

Andrea Rodgers, Senior Litigation Attorney with Our Children’s Trust, said, “It is an affront to justice that when children are being harmed by specific legal actions their government has taken, they have no recourse. It is a sad day for Canada and democracies around the world, and judicial restraint in the face of the climate crisis will one day be seen as one of the world’s great follies. For these children’s sake, we are hopeful that this miscarriage of justice will be corrected on appeal.”

Attorneys for the youth plaintiffs will appeal today’s decision. As noted by 16-year-old plaintiff Haana, “The decision to strike all claims is disappointing but not discouraging; what we are doing is important work, and there are many next steps ahead.”

Sadie, 14, said, “I’m concerned for my future, the future of the world and the future of Canada if we continue to act like we are now. I need this case to continue for the safety of all the young people in Canada. But, this case is not over. Us young people will never stop fighting for our future.”

“Of course this decision is disheartening, but the journey is far from over,” David Suzuki Foundation CEO Stephen Cornish said. “These brave young plaintiffs aren’t done calling for an adequate, science-based climate recovery plan in Canada. They know we only have a decade to turn things around and that, so far, we’re not on track. These kids are on the right side of history. They deserve their day in court.”

Arvay, QC, and Catherine Boies Parker, QC, of Arvay Finlay LLP, and Chris Tollefson and Anthony Ho of Tollefson Law Corp., and supported by Andrea K.
