The Office of the U.S. Trade Representative has added Canada's zero plastic waste program to its 2026 National Trade Estimate, a yearly catalog of trade barriers the agency uses to pressure trading partners. The 2026 NTE also lists CUSMA disputes over bridges and aluminum tariffs.

The Canadian ban, phased in since 2018, covers six single-use plastic categories. The last rule — plastic ring carriers — took effect in 2024. Ottawa's program now sits in a filing that signals formal bilateral pressure on a circularity policy.

What does the ban's track record show?

Shoreline cleanup tallies filed with a recent Senate committee show a 60% decline in plastic straw litter and a 25% drop in single-use bag litter since the 2018 phase-in. Microplastics in Great Lakes water "have plummeted" since the earlier microbead rule took effect, experts told the same committee.

Cleanup volunteers report the figures, which Environment and Climate Change Canada aggregates. They cover items the ban targets directly: straws, bags, cutlery, stirrers, ring carriers, and microbeads.

Reported impact of Canada's single-use plastic rules:

• 60% decline in plastic straw litter (since 2018)
• 25% decline in single-use bag litter
• Microplastics in Great Lakes "plummeted" post-microbead rule
• Six product categories covered; ring carriers added 2024

What does USTR want changed?

USTR has not specified which Canadian measures it wants rolled back. The 2026 NTE is a negotiating instrument, not a formal WTO complaint. The American Chemistry Council and U.S. plastics manufacturers have lobbied for years to weaken Canadian rules.

The trade filing puts a bilateral track on a policy that previously operated as a domestic regulatory measure. Any rollback would require either a federal regulatory amendment or a CUSMA dispute ruling.

What does the EV battery reuse pipeline look like?

Vancouver-based Moment Energy has begun operating what it describes as the world's largest electric vehicle battery repurposing megafactory. The facility targets one gigawatt-hour of annual output by 2030, converting retired automotive packs into stationary grid storage.

Backers include the Amazon Climate Pledge Fund, the governments of Canada and the United States, and additional undisclosed private capital. The bet: first-generation EV batteries lack the cycle life for automotive duty but remain viable for grid-scale storage.

Global battery capacity grew 66% in 2025 to 302 GW, according to the Energy Institute's 2026 Statistical Review of World Energy — a demand pull that makes second-life economics workable.

What happens next on the file?

CUSMA's six-year joint review window opens in 2026. Any decision to scale back the zero plastic waste program would land in that cycle, alongside outstanding disputes over steel, aluminum, and softwood lumber.

Prime Minister Mark Carney has signaled a willingness to keep the program's stated ambition while accepting higher near-term emissions elsewhere in the economy. He described the inherited climate plan as "too expensive" and "too divisive."

For Circular Wire readers, the watch items are:

• USTR's next bilateral consultation under CUSMA
• Canada's 2027 progress report on the single-use plastic ban
• Moment Energy's first commercial deliveries from its Metro Vancouver facility
