OTTAWA — Ecojustice lawyers and their client, the David Suzuki Foundation, are confident that the Supreme Court of Canada will uphold the federal government’s legal authority to implement national measures to combat climate change.

The provinces of Ontario and Saskatchewan are appealing lower court rulings that upheld the constitutionality of the Greenhouse Gas Pollution Pricing Act and affirmed the federal government’s ability to ensure all levels of government do their part to tackle the climate crisis. British Columbia is appealing the Alberta court’s ruling that the federal carbon-pricing law is unconstitutional.

The Supreme Court of Canada will be the last stop in deciding whether the government can continue with its national climate plan, which includes putting a price on carbon emissions.

Ecojustice lawyers, on behalf of the David Suzuki Foundation, will argue before the court on Sept. 23, 2020 that Canada has the duty and the legal authority to ensure that all levels of government do their part to respond to the climate emergency with a national carbon-pricing policy.

Representatives from the groups made the following statements in advance of their court appearance this week.

Joshua Ginsberg, lawyer with Ecojustice’s law clinic at the University of Ottawa said:

“Provincial opposition to meaningful climate action remains a massive stumbling block to Canada’s climate progress. Even as industry support grows for common sense, proven climate solutions — like carbon pricing — some provinces actively oppose these measures.

“The window of opportunity to turn the tide on the climate emergency is now. Over the past few months, we’ve seen what governments across the country can do when they work together to tackle a global health threat.

“We are confident that the Supreme Court of Canada will make clear that tackling the climate emergency with urgent, unified, science-based action nationwide is the shared responsibility of provincial and federal governments.”

Ian Bruce, David Suzuki Foundation chief operating officer said:

“As we’ve seen with Canada’s response to the pandemic, we’re all well-served when we work together and listen to the science. Putting a price on carbon is a critical part of any fair and effective climate plan. Canada must have the power to enact a climate recovery plan for the sake of our health, our children and future generations.

“This is not the time to delay action because a few provincial leaders are unwilling to follow what climate science says is necessary. Inaction is not an option and no jurisdiction can shirk its responsibility to act. All people in Canada deserve to be protected through a national approach to address the climate crisis.”
