The GM Oshawa Assembly plant started building the 2022 Chevy Silverado HD late last year and will begin production of the refreshed 2022 Chevy Silverado 1500 this spring. Once production of the light-duty Chevy Silverado begins in a few months or so, Oshawa Assembly will be the only GM truck plant building both light-duty and heavy-duty pickups side-by-side.
In addition, the Canadian GM truck plant is also the only facility that will build only the Chevy Silverado and not the GMC Sierra. The automaker’s other truck plants, which include Flint Assembly, Fort Wayne Assembly and Silao Assembly, all produce both the Chevy Silverado and GMC Sierra.
Speaking to Automotive News, GM Canada president Scott Bell said the fast turnaround on the Oshawa plant’s renovations meant GM had to make some sacrifices with the plant – resulting in the GMC Sierra nameplate being dropped from the facility’s roster.

The Oshawa facility was reopened and retooled in order to create more pickup truck production capacity for GM at a time when demand for full-size trucks is at an all-time high. When GM first announced it would be reopening the plant in November of 2020, the automaker said producing more pickups would help it fund its coming EV product onslaught.
Once up and running at full capacity, the GM Oshawa Assembly plant will employ roughly 1,700 workers.

Fort Wayne used to produce 1500-3500, not sure when/why that changed. It was a little screwy with the duallys though, they were too wide to fit through parts of the plant (paint shop I think?) so for parts of the process the rear fenders were on a second fixture behind the rest of the truck. Been a lot of changes since I was there last though.
I think Mexico and Fort Wayne still produce HDs 🤔
I believe that Fort Wayne and Mexico only build 1500’s. 2500’s and 3500’s come out of Flint MI, and that’s the only thing Flint builds. At least that’s what I was told when I ordered my 1500 Denali last spring, which was built in Fort Wayne.
No they don’t. Fort Wayne and Silao are LD only. I believe it changed during the T1 platform retooling.
I would never buy a GM Canada made vehicle after they fired unvxd workers.
My vin will likely have the 2 country code then. Configurator goes live tomorrow, I’ll be building my future 1500 on the beach in Jamaica. My wife thinks I’m a loser. Yea, a loser with a new duramax!
I would never buy a vehicle from a company that would fire employees for refusing a medical procedure.
any idea what all the delay is at the Oshawa plant?
