Canada's auto industry is urging the new Carney government to hold firm in upcoming trade negotiations, with one sector insider describing the mobilization effort in blunt terms as having "gone to the mattresses."

The phrase, reported by iPolitics, signals the depth of concern across the industry's supply chain as Ottawa prepares for talks that will shape the terms under which vehicles and parts cross the border. The industry's message to the government is simple: do not concede ground that would undercut North American production economics.

Who is making the argument?

The pressure comes from the auto sector broadly — OEM-linked interests and the supplier base that depends on tariff-free, predictable cross-border flows. Canada's parts makers sit heavily inside the USMCA trade loop, shipping components to assembly plants in Ontario and the United States multiple times before a finished vehicle rolls off the line.

Their argument to the Carney government is that any weakening of trade terms translates directly into production risk: programs can shift, tooling can move, and supplier contracts follow the assembly footprint. That is why the sector is pressing Ottawa to treat automotive as a strategic, non-negotiable file rather than a bargaining chip.

What does "staying strong" mean in practice?

For the industry, firmness in trade talks means defending the access Canadian-built vehicles and Canadian-made parts currently enjoy in the US market. The sector's mobilization — the "gone to the mattresses" posture — reflects a conviction that the negotiating environment has hardened and that only a unified, aggressive industry front will keep automotive interests at the top of the government's priority list.

The arrival of a new government under Mark Carney has opened a fresh window for that lobbying. Industry players are moving early to set the negotiating mandate before talks begin, betting that positions harden once officials sit down at the table.

What to watch next

The signals to monitor are concrete: the composition of Canada's negotiating team, the automotive language in any mandate letters issued to the trade minister, and whether Ottawa publicly commits to preserving existing tariff-free access for vehicles and parts. Each of those will indicate whether the industry's early pressure has translated into negotiating capital — or whether the sector will need to press harder as talks progress.
