GM Oshawa Will Build the Legacy Silverado, Not the 2019 Truck by Evan Williams December 21, 2017December 21, 2017 Share Comments The new 2019 Silverado is on the way, which means changes to General Motors’ Oshawa plant to make the new trucks, right? Not just yet. Automotive News reports that the Oshawa, Ontario plant is going to keep building the current truck “for the foreseeable future”. In typical GM fashion, the old trucks will be sold alongside the new ones for the foreseeable future. “The length of the program in Oshawa will be dependent on market demand,” GM spokeswoman Jennifer Wright told the publication. Building the current model means finishing trucks already started at the Fort Wayne, Indiana plant that started them. 2018 Model year trucks will be shipped north for paint and assembly. GM CEO Mary Barra said recently that she expects the Oshawa plant to build 60,000 trucks a year. GM is spending $310 million to upgrade the consolidated line at the Oshawa plant. It used to handle overflow production of the Chevrolet Equinox, but will now build half-ton trucks. That upgrade is part of the most recent contract with the automaker and Unifor, the union that represents GM workers there. GM is spending $3 billion to upgrade plants in Mexico, Michigan, and Indiana to build the next-generation trucks. It’s not yet clear when or even if the new trucks will start to roll off the line in Oshawa.
