Ottawa defends carbon pricing in Alberta court
BOB WEBER
The climate crisis is a national and global issue that can’t be fought entirely by the provinces, a lawyer for the federal government argued Tuesday.
“The context of this case is the greatest existential threat of our time,” said Sharlene TellesLangdon in her opening arguments in support of Ottawa’s carbon tax.
The law that brought in the tax is being challenged this week by Alberta in the province’s Court of Appeal.
Ontario and Saskatchewan have also gone to their top courts to oppose the tax, but lost. They are appealing to the Supreme Court of Canada.
Ottawa argues its authority for the tax comes from the Constitution’s peace, order and good government clause. Establishing minimum national standards on greenhouse gas emissions “is a matter of national concern that only Parliament can address.”
Telles-Langdon argued in court that the circumstances surrounding climate change have developed enough to make it a national concern. Much more is known about it, she said, and the severity of the threat has greatly increased.
“There has been a constitutionally important transformation,” she said. “We’re now in a situation where the dimensions of the problem are international and global.”
The carbon tax flows from the federal government’s right to sign international treaties, she added, and is part of living up to climate change accords such as the Paris Agreement.
“The treaties matter,” TellesLangdon said.
She told the five-judge panel that the carbon tax grew out of co-operation between the federal government and the provinces that began in 2016 after a first ministers meeting in Vancouver. The provinces agreed at that time that carbon pricing shouldn’t make businesses in one province less competitive in comparison with others.
Several provinces already had carbon-pricing schemes at that time, she said. “When this was signed, part of the agreement was that other provinces be brought on board.”
She argued that the tax still gives provinces the flexibility to meet a minimum standard in their own way. She pointed to Alberta’s recently approved levy on industrial emitters.
The federal lawyer faced repeated questions from judges about the scope of the legislation and how it would be implemented. In response to a question on whether Ottawa could simply ignore competitive pressures on Canadian businesses, Telles-Langdon pleaded with the court “to be reasonable about what Parliament does.”
“The federal government has to be very cognizant of the economy of the country as a whole.”
