Cyril Lewis was born on Union Island, one of a group of islands in the West Indies known as the Grenadines. His father was a teacher and principal, and prior to coming to Canada, Cyril taught at the high school he attended: St. Vincent Grammar School.
Once here, Cyril went to Sir George Williams University (now Concordia University) in Montreal and received a Bachelor of Science degree. He went on to get an engineering degree from McGill University. Cyril taught with the North York Board of Education for two years before going back to school for his master’s degree at Queen’s University. While there, he also taught undergraduate courses.
In 1975 he went to the Scarborough Board of Education and became assistant head of
mathematics at Albert Campbell Collegiate. He has worked with mathematics leagues and many contest teams. He has been a Descartes Contest marker, a curriculum writer, and has worked with peer tutoring programs in his school. In addition, for about 20 years Cyril has taught electrical courses at Centennial College.
Cyril has won a Prime Minister’s Award for Excellence in Teaching plus an Edith May Sliffe award from N.C.T.M. for Distinguished High School Mathematics Teaching.  He is an accomplished cricket player and an avid gardener.
