Oshawa: GM ends Silverado 1500 production this month

General Motors will end production of the Chevrolet Silverado 1500 at its Oshawa Assembly plant in November, the company confirmed during its third-quarter earnings call. The Oshawa plant will not build the next-generation Silverado 1500, GM Authority reported.

The changeover to the redesigned 2027 Chevrolet Silverado 1500 and GMC Sierra 1500 remains on schedule, according to GM. Production of the new trucks has begun at GM's Silao Assembly plant in Mexico, and the company says the first trucks should reach dealerships later this year, with V8-powered Crew Cab models arriving first.

Fort Wayne Assembly in Indiana is scheduled to pause production for four weeks beginning in mid-December, then restart in January building the new trucks. Production is scheduled to begin at Orion Assembly in Michigan in the second quarter of 2027.

"We're focused on a flawless launch," GM Chair and CEO Mary Barra said during the company's third-quarter 2026 earnings call. "It's on track right now." Barra said GM expects to build roughly the same number of Chevrolet Silverado and GMC Sierra trucks in 2027 as in 2026, with more capacity available in 2028 once changeover downtime ends and Orion joins the production network.

GM says the sell-down of the outgoing trucks is on plan, with inventory at expected levels. Incentives as a share of the sticker price are several hundred basis points lower than during the previous full-size truck changeover, an indication GM is relying less on discounts to clear remaining stock.
