Sir Winston Churchill is a comprehensive school of approximately 2,000 students in Grade 8 - 12.

It offers a rich and varied program that includes traditional academic courses as well as extensive Art, Business Education, Music, Drama, Home Economics, ESL, and Technology programs. The school's large athletic program includes numerous major and minor sports, many of which have earned championships at the city and provincial levels. Its widely acclaimed student government organizes a variety of intra-mural and social activities and increasingly enjoys a voice in the school's decision-making processes.

In recent years, three Churchill teachers received Prime Minister Awards for Teaching Excellence. Many students each year are recognized for their academic achievements.
