GM’s Canadian workers approve deal adding truck to Ontario plant amid US trade war

Aug 30 (Reuters) – General Motors workers in Canada on Sunday approved an agreement that would build a new heavy-duty truck in Ontario, part of a pledge by the automaker to ​invest in a country now facing a doubling of tariffs.

Canada’s ‌auto sector is grappling with 25% U.S. duties on vehicles, and U.S. President Donald Trump has vowed to lift that to 50% on January 1, 2027. The fate of Canadian auto plants has emerged as a central issue in the ‌stalled ​U.S.-Canada trade negotiations.

According to details of the ⁠agreement released by the Canadian ⁠union Unifor on Saturday, GM offered to spend C$144 million to add the next-generation heavy-duty GMC Sierra truck to a plant in Oshawa, and pledged not to immediately sell or close a second ​assembly plant in Ingersoll, Ontario.GM has promised to invest over C$1 billion ($720 million) in Canadian plants. That includes a C$691 million commitment ⁠to support production of new V8 ⁠engines in Ontario that was previously announced in April, ​according to Unifor, which represents 4,600 GM workers in the province.

The deal ​offered Canadian workers a 3% wage increase a year over ‌three years.

“The new agreements include meaningful improvements to wages, benefits and job security, and recognize the valuable contributions of our represented employees while helping sustain good-paying jobs that have long been a cornerstone of Canada’s ⁠automotive industry,” Jack Uppal, GM Canada president, said in a statement.

U.S. and Canadian trade talks ended last week over unresolved issues, such as whether to ⁠cut duties on ‌medium- and heavy-duty vehicles that are critical for Canadian ⁠factories.

U.S. automakers had hoped the trade talks would ​deliver relief ‌from Washington’s original 25% tariffs that have raised ​the cost ⁠of shipping vehicles and parts across the border.

About 17% of GM’s Chevrolet Silverado pickup-truck production – its top-selling model – is in Canada, according to research from Barclays.
