The Canada Life Building is a historic office building in Toronto, Ontario, Canada. The fifteen-floor Beaux Arts building was built by Sproatt & Rolph and stands at 285 feet (87 m), 321 feet (97.8 m) including its weather beacon.

It is located at University and Queen Street in the city's downtown core. Work on the new headquarters of the Canada Life Assurance Company began in 1929 and it opened in 1931. It was the fourth building to serve as the headquarters of Canada Life, Canada's oldest, and at the time largest insurance company. Previously it had been housed in offices at Bay and King Street.

The Beaux Arts structure was the first of a series of planned structures along University Avenue, but the Great Depression halted these plans. When it was completed it was one of the tallest buildings in Toronto. It remains one of the largest office buildings in Toronto with windows that can be opened by its occupants.

The Canada Life Campus has been expanded several times over the last few decades and now consists of five structures: 330 University Avenue, 190 Simcoe Street, 180 Simcoe Street, 180 Queen Street West and a 5-storey parking garage at 206 Simcoe Street. In addition, the Campbell House Museum was moved to the south-east corner of the campus in 1972.

The building is perhaps best known for its weather beacon, whose colour codes provide summarized weather forecasts at a glance. The information is updated four times every day by Environment Canada's Weather Centre at Toronto Pearson International Airport. The forecast is for the next 4 hours. The top light shows:^[2]

The beacon was the first of its kind to appear in Canada and was built at a cost of $25,000 (equivalent to $249,296 in 2021). The top of the beacon tower stands 321 feet (97.8 m) above University Avenue and, when completed on August 9, 1951, made the structure the third-highest in Toronto, after the Canadian Bank of Commerce Building and the Royal York Hotel.
