Cornerstone Christian Academy is an Interdenominational, Evangelical Christian School serving the Lord in the Lennox and Addington area. Cornerstone is a member of the Association of Christian Schools International (ACSI), and was founded in September 1994. In its first year of operation, two teachers opened the doors to 27 students and we have grown since then.

Cornerstone is presently housed in the Education Wing of Evangel Temple in Napanee, Ontario. The school has use of several classrooms, a gymnasium, computer lab, kitchen, a large yard for play, and the sanctuary for chapel services, school concerts and programs.

Cornerstone is registered with the Ontario Ministry of Education. It is also registered as a not-for-profit corporation. A Board of Trustees oversees the operation of the school.
