Queen's College was established in Kingston, Ontario by the Presbyterian Church of Canada in association with the Church of Scotland in 1841. The following year classes began in a rented building with 2 professors and 10 students. It was primarily intended to train men for the ministry. Its ties to the Presbyterian Church slowly diminished and in 1912 the separation of church and state was complete with its charter amended becoming Queen's University at Kingston. Queen's currently has approximately 13,500 full-time undergraduate students, 2,900 graduate students and a staff of 4,200.
