During the last major set of renovations, undertaken in 1989, a second and third floor extension was made, jutting out as a protective arcade with green-glass solarium on top, along the southern side of the building.

The broadcast station includes a virtual television studio whereby anchors sit in front of a green screen and robotic cameras are controlled from remote cities.

For decades until 2020, the main Montreal Tourism office occupied the southeast corner of the ground floor (facing Dorchester Square).

Between 2003 and late 2019, the principal tenant was the Montreal Gazette, which had placed a marquee title holder atop the arcaded entrance along Saint Catherine Street.

Its modern conveniences and amenities, the prestige of location and effective beauty of the design made it an exceptionally important commercial office tower in the era before Modernist Skyscrapers.
