The Mutual Life Assurance Company of Canada was incorporated in December 1868 as the Ontario Mutual Life Assurance Company, changing to its present name in 1900. However, its Head Office has always been located in Waterloo, and the Company and the City have grown together over the years. The present Head Office building was erected in 1912, with an addition in 1921 which duplicated exactly the original architecture. It is the facade of this 1912-21 building that is being designated today.
