Sisler High School is the largest high school in the province of Manitoba with over 1800 students. It was built in 1957, and named after William James Sisler. As principal of Strathcona School in the North End of Winnipeg, W.J. Sisler was instrumental in helping new immigrant families adjust. He faced a great challenge in the fact that a majority of the students did not speak English; there were twenty-two countries of origin and eighteen language groups in his student body.
