Terry Guest was Headmaster of Lakefield College School from 1971-1985; while he was there, Lakefield became the first Canadian school to become a member of Round Square, a group of international schools which adhere to the philosophy of education espoused by Kurt Hahn. After Lakefield, Terry became the Head of Sedbergh School in Montebello, Quebec, and then Bayview Glen, a multicultural day school in Toronto. The enrolment at BVG grew from under 300 pupils to 1000 during his headship (1990-2001) and continues to flourish. Terry became the Executive Director of Round Square while in Toronto, and in 2007 received an award from H.M. Queen Elizabeth II, being named a Commander of the Victorian Order, as well as receiving Gold and Diamond Jubilee Medals in recognition of his service to education. In 2012 Terry paddled in the Canadian Canoe Museum’s north canoe, representing Canada in the Jubilee Flotilla on the Thames.
Since retirement, Terry has been actively involved with the Canadian Canoe Museum, and the restoration and operation of Hope Mill, both in the Peterborough area, where he and his wife, Sue, enjoy country living in a century-old log house.
