Initially located in Senator Gibson’s former home in Beamsville, Ontario, the school has undergone significant expansion since its inception. With an initial enrolment of just 14 students in Grades 9 and 10, the institution quickly grew, extending its curriculum to Grades 11 and 12 by 1953, and seeing enrolment rise to 36.

The ensuing years witnessed remarkable growth and diversification. In 1965, College Hall, the main academic building, opened. By 1980, enrolment peaked at 200, a historic high for the school. Through periods of economic uncertainty and even a global pandemic, GLCHS demonstrated resilience, ensuring continuity in service delivery, maintaining steady enrolment, and even expanding into new areas, such as introducing the Great Lakes Christian Preschool in 1996.

In 2008, reflecting the institution’s focus on high school education, GLCC rebranded as GLCHS, a change reflected across all promotional materials. In 2017, GLCHS took a significant technological leap, launching a 1 to 1 program, offering individual computers to all students – a move that proved crucial during the global COVID-19 pandemic.

The past few years have seen significant milestones for GLCHS. In 2021, the school completed the Vision 2020 Capital Campaign, bringing key updates to the Ellis Hall and ensuring its accessibility and compliance with modern building codes. By 2022, the school had launched the Clean Air Campaign, improving air circulation and purification in classrooms.

Celebrating 70 years of operation in 2022, GLCHS stands as a testament to Christian education’s enduring value, having served over 3,000 students. As we look to the future, we remain committed to providing a nurturing, Christian-based educational environment for generations to come.
