Sun Life Building

The Sun Life Building is a monumental office skyscraper located in downtown Montreal, celebrated for its stately architecture and symbolic significance. Completed in stages between 1913 and 1931, it was designed by the architectural firm Ross and Macdonald, along with engineer Max Aitken. While its earliest sections were more classical Beaux-Arts in spirit, the final phase, completed in 1931, incorporated strong geometric ornamentation and stepped forms characteristic of the Art Deco style. Its imposing 24-story profile and limestone façade established it as the largest building in square footage in the British Empire at the time.

During World War II, the Sun Life Building gained further renown when the British Crown Jewels and other valuables were secretly stored in its underground vaults for safekeeping. Today, it remains a powerful presence in Montreal’s skyline, admired for its elegant massing, setbacks, and refined geometric details that echo Art Deco sensibilities. Its interior and exterior have been carefully maintained, preserving its historical grandeur while providing modern office amenities.
