In 1903, building commenced on the first addition to the school (since then, ten other additions have been made). While construction was taking place, some classes were moved to the City Hall and to Kitchener's Carnegie library. On November 30, 1904, a Provincial-Order-in-Council raised the school to the status of a collegiate institute, and the school became the Berlin Collegiate Institute. By 1905 the new building was in use. The school changed names along with the city in 1916 to Kitchener Collegiate Institute.
