The GMC Sierra Will Not Be Produced At Oshawa Assembly

The GM Oshawa Assembly plant will only produce the Chevy Silverado 1500 and Chevy Silverado HD and will not build any examples of the closely related GMC Sierra 1500 or GMC Sierra HD.

GM Canada has confirmed to GM Authority that the Oshawa Assembly plant, which was recently re-opened and re-tooled to produce GM’s full-size trucks, will only build the two Chevy Silverado model variants. This makes Oshawa Assembly the only GM plant dedicated to building the Chevy Silverado.

GM builds the Chevy Silverado HD and GMC Sierra HD at its Flint Assembly plant in Michigan, while the GM Fort Wayne Assembly plant in Indiana and GM Silao Assembly plant in Mexico produce the light-duty versions of the two pickups.

GM Canada did not say why it will not produce the GMC Sierra at Oshawa Assembly, although it seems likely that this decision was related to volume. The Oshawa plant was re-opened to give GM additional production capacity for its pickups amid increasingly high demand, but the Chevy Silverado sells in much higher volumes than the GMC Sierra, so this extra capacity was likely only needed for the Silverado.

“Pickups are GM’s largest and most important market segment across the continent, and the Oshawa plant will help GM meet strong demand for its leading family of pickup trucks,” the automaker said in a statement in November.

The first 2022 Chevy Silverado HD built at the Oshawa facility rolled off the production line in early November. The plant is only building the Silverado HD at the moment, with light-duty truck production set to commence in 2022. GM had initially targeted a January 2022 production start date for Oshawa, but pulled the date forward to December 2021 after carrying out “one of the fastest plant launches in GM history,” according to GM Canada president Scott Bell.

  1. Awesommme! So my High Country will be built not too far from where I live.

    1. Maybe. FT Wayne and Silao are still building light duty Silverados and Flint is still building HD Silverados. Oshawa didn’t take any production of trucks from other shops, they are a flex plant. This means they have a slow line speed and low volume production so the other shops can build more Sierras and still build plenty of Silverados. If you buy an HD Silverado the only body style you will get from Oshawa is the for door short bed.

      1. Oshawa makes short and long boxes. I drove by the shipping compound the other day and noticed the box differences.

  2. I guess verify you are not getting the Mexican junk before you sign and drive

    1. Fatone you are absolutely right you don’t want that Mexican piece of junk. But these sneaky car dealers will try to sell you one without you knowing it is assembled in Mexico. Buyer BEWARE.

      1. Just check the VIN before you test drive.

      2. Jesus. The Mexican plant has to meet the same quality standards as the US plants and now Canadian plant. Just say you hate brown people and get it out of the way.

        1. You aren’t very good at race baiting but nice try.

          1. They should all be built in The US!

        2. Some us who live in the real world and are don’t think everything is race based know managing quality in factories in different countries is challenging. Honda struggled with quality in their first plants in USA. Ford shipped by train hundreds of thousands from their original Mexico plant back to Dearborn to quality control. Do some research instead of being a one trick race identity pony

        3. It’s about jobs you dumbass.

        4. I would love to buy a truck made in Mexico if;

          1, Americans who had worked loyally for decades weren’t dumped to the curb for a couple extra buck per unit sold

          2, if the reason that labor is cheaper in Mexico wasn’t because the oligarchs there realize that they can steal American jobs by just ruining the Mexican economy just enough that people are desperate for any job they can get and then keeping the cartels alive so they are not the bad guys.

        5. That, and if you look at aging GM vehicles, compare the condition of the paint, fit, and finish. There’s a reason for all of those Buick sedans still going, and still looking good after one or even two decades on the road. Look at the VIN, and it likely starts with a “3”.

        6. A Chev is just a Chev no matter where it is built. Mexican built
          GM trucks don’t come with 3 wheels and no windshields !

    2. If Vin starts with “3”, it’s from south of the border.

    3. I’ll take Made in Mexico over Made in China any day.

  3. Seems odd that this plant would not build the Sierra. I believe Canada is the only country where the Sierra outsells the Silverado.

  4. They have to make room for the Geo Metro.

  5. The Sierra is outselling the Silverado currently and will continue to unless GMC dealers are handcuffed by production constraints like this.
