The 2026 GMC Sierra 1500 delivers a full spectrum of capability, from the work-ready Pro to the refined Denali Ultimate. Each trim offers distinct engines, towing power, and features designed to match your specific needs. This guide breaks down every option so you can confidently choose the Sierra 1500 that fits your lifestyle in Ontario.
From turbo four-cylinder efficiency to V8 authority and diesel torque, the Sierra 1500 lineup covers serious ground. Off-road enthusiasts can choose factory-lifted AT4 models with locking differentials, while luxury buyers will find premium interiors and hands-free driving technology in Denali variants. Understanding the differences between trims ensures you get exactly what you need without paying for features you won't use.
The Pro trim is built for professionals who need dependable capability without excess. It starts with the 2.7L TurboMax engine, delivering 310 horsepower and 430 lb-ft of torque through an 8-speed automatic transmission. This turbo four-cylinder handles up to 4,309 kg (9,500 lbs) of towing capacity while maintaining fuel efficiency for daily work routes.
Standard features include 12 cargo tie-downs for securing loads, a 12V front power outlet for jobsite tools, and rear-wheel drive. The Pro keeps things simple with basic infotainment and GMC Pro Safety technology.
