and the GMC Sierra 1500 would be sold alongside their successors for the 2019 model year, as the Chevrolet Silverado 1500 LD and the GMC Sierra 1500 Limited. Final assembly of these trucks, which would only be sold in Double Cab, Standard Bed form, would occur at Oshawa Car Assembly. This marks the first time since 2009 that Oshawa Assembly (Oshawa Truck Assembly), which also assembled the Chevrolet Silverado 1500 and the GMC Sierra 1500 in Extended Cab form, would assemble trucks. Later that summer, GM also began final assembly of Chevrolet Silverado HD and GMC Sierra HD Double Cab models. On November 26, 2018, General Motors announced the closure of the Oshawa car assembly plant complex ending 111 years of auto manufacturing in Oshawa. The final vehicle, a white GMC Sierra pickup truck, rolled off the assembly line on December 18, 2019. On November 4, 2020, GM announced “Subject to ratification of the 2020 agreement with Unifor, General Motors plans to bring pickup production back to the Oshawa Assembly Plant. Construction will begin immediately at Oshawa Assembly and will include a new body shop and flexible assembly module, to support a fast response to strong customer demand for GM’s new family of pickup trucks.” Oshawa pickup production started on November 10, 2021 when the first Canadian-made Silverado was completed.
