About OEC

The Ontario Engineering Competition (OEC) is an annual student-run, three-day competition that brings together more than 300 of the province’s brightest students. Competitors demonstrate their engineering skills in a competitive environment, while also developing meaningful relationships with their peers. Over the past 46 years, the competition has grown to become one of the largest and highly anticipated engineering competitions in Canada. McMaster University is proud to have been chosen to host in 2025.

Qualification for OEC

For a team to qualify for OEC, they must win their respective university's qualifier competition. Teams are composed of 2-4 delegates, and there are nine available categories from which to compete: Junior and Senior Design, Programming, Debate, Re-Engineering, Consulting, Communications, Innovative Design, and Bio- Engineering. These categories test delegates' innovation, problem-solving, and leadership skills - all key qualities of a successful and well-rounded engineer. The highest performing teams from OEC will then represent Ontario at the Canadian Engineering Competition (CEC), to be hosted in 2025 by Dalhousie University.
