161 Liberty is listed in the City of Toronto’s inventory of Heritage Properties as a well-designed early-20th century industrial building with features of Edwardian Classicism. Built in 1910 for S. F. Bowser & Co., producers of oil tanks, the building replaced a baseball stadium named Diamond Park. It’s a three storey, brick and beam structure with towering operable windows, high ceilings, hardwood floors and a fine Toronto red brick masonry exterior.
