GM Authority can exclusively reveal that the Chevy Silverado HD heavy-duty pickup truck and its corporate cousin, the GMC Sierra HD, will be the first vehicles built at the GM Oshawa plant in Ontario, Canada when it re-opens this fall.
Vehicle manufacturing in the area dates back to the 19th century, when the McLaughlin company built first horse-drawn carriages and later automobiles. It then became the birthplace of many GM vehicles, latterly including the now discontinued Chevrolet Impala and Cadillac XTS.
Vehicle production at Oshawa ended in December of 2019 – a GMC Sierra built at that time was raffled off, raising $117,000 CAD for the Durham Children’s Aid Foundation. Thereafter, General Motors intended to use the factory for parts production and metal stamping, and built a test track for autonomous vehicles.
Michelle Burnham, Buick GMC Product Communications Manager, GM Canada, declined the opportunity to reveal production mix plans when speaking to GM Authority. However, she did say, “We are designing the Oshawa facility to be flexible, so we can align our production with customer demand.”
The 2022 Chevy Silverado HD and 2022 GMC Sierra HD will differ only in detail from their 2021 model-year equivalents. Both will be powered either by the naturally aspirated 6.6L V8 L8T gasoline engine, which produces 401 horsepower and 464 pound-feet of torque and is mated to GM’s six-speed automatic transmission, or by the turbocharged 6.6L V8 L5P diesel from the Duramax family, which makes 445 horsepower and 910 pound-feet of torque and is paired with a 10-speed automatic.
