Our Leadership

Marissa West

GM Canada President and Managing Director

Marissa West leads GM Canada at a pivotal time, as the automotive industry shifts to electrification. In this role, Marissa’s focus is supporting customers, dealers and employees as GM prepares for an all-electric future. Among Marissa’s key priorities are leveraging GM’s Canadian Technical Centre as a hotbed of innovation, and continuing to improve gender equity, diversity, and accessibility in the workplace and in GM’s vehicles.

In the 20 years she’s worked at GM, Marissa has held a variety of engineering roles in multiple departments. Marissa was Executive Chief Engineer for GM’s Global Mid-Size Truck and Medium-Duty Truck programs and the Chief Engineer for the Next Generation Full-Size Truck programs before that. In that earlier role, her team launched the 2020 GMC Sierra HD and the Chevrolet Silverado HD, and was responsible for leading other full size truck programs representing US$1.6 billion in investment and more than 1.4 million vehicles produced annually.

Before becoming Chief Engineer, Marissa led the Global Noise and Vibration Center and later orchestrated and led the merger of two distinct GM engineering centres into one agile, efficient organization. To support GM’s vision of accessible transportation, Marissa formed GM’s Accessibility Center of Excellence, which works across the entire organization using technology and innovation to unlock barriers to mobility.

As the Chief of Staff to the Executive Vice-President of Global Product Development, Purchasing and Supply Chain, Marissa was instrumental in coordinating product processes from start to finish and working cross functionally to deliver enterprise-wide results.

Beyond her engineering work, Marissa is passionate about encouraging girls and underrepresented minorities to pursue education and careers in STEM and in 2018 she was nominated for a Society of Women Engineers (SWE) award for “Advocating in Women in Engineering”.

She holds a master's degree in mechanical engineering from the University of Michigan and a bachelor's degree in mechanical engineering from Michigan State University, which included engineering studies at RWTH Aachen University in Germany. Additionally, she has completed Positive Leadership and Design Thinking executive training through the University of Michigan and the Transformational Leadership Executive Education Program at Stanford.

Marissa lives in Toronto with her husband Bob and their four children.
