The Supreme Court of Canada said Thursday it will hear an appeal that will determine if Ottawa’s ban on single-use plastics can remain in place.

In 2022, Ottawa phased in a ban on the manufacture and sale of six single-use plastic items, including straws, stir sticks, cutlery, takeout containers and the six-pack rings used to hold soda and beer cans.

The government said at the time it chose those items because they were commonly found in litter and had known and accessible alternatives.

In order to introduce the ban, the federal government listed “plastic manufactured items” as toxic under the Canadian Environmental Protection Act, following a scientific assessment.

In 2023, the Federal Court said that listing was too broad, in part because the federal government had failed to demonstrate that all plastic items harm human health or the environment.

The Federal Court of Appeal overturned the lower court’s decision in January, allowing the federal government to keep the ban in place. The three-judge panel unanimously ruled the decision to list plastic manufactured items as toxic was reasonable.

They argued the lower court had erred by viewing as one step what was actually a two-step process: designating plastics as toxic under the Act and regulating individual plastic items.

The initial decision to list all plastics as toxic was challenged by a group representing companies in Canada’s plastics industry, along with three chemical companies which manufacture plastics.

The plastics industry argued, among other things, that a lack of testing to determine which plastics are harmful made Ottawa’s decision unreasonable.

The Court of Appeal dismissed that argument in January.

“To put the matter bluntly … the chemical content of (plastics) is irrelevant to the sea otter choking on a plastic straw. The problem is the plastic item itself, not its chemistry,” the judges wrote.

Karen Wirsig, senior program manager for plastics at Environmental Defence, said until the Supreme Court rules, Ottawa should maintain the ban.

“It is rare for appeals to be granted so we were not particularly expecting it. However, it does open the opportunity for a stronger precedent for the listing from the Supreme Court of Canada,” Wirsig told The Canadian Press.

The group representing plastics companies has not yet responded to a request for comment.
