Built in 1930 as a showroom for Pierce-Arrow.
Long before it carried the name 1 Marlborough, this corner of Yonge Street was the Canadian showroom of the Pierce-Arrow Motor Car Company. The arches that framed its cars are being restored as the base of the new building.
1930
The showroom
Sparling, Martin and Forbes designed a grand gallery for Pierce-Arrow's new Straight-Eight models.
1954
CBC studios
The CBC bought the building and filmed Mr. Dressup, Front Page Challenge and The Wayne and Shuster Show here.

A Yonge Street storefront
The arches stayed through decades of retail, framing a Staples on the corner.

The developer's published building-performance measures, grouped by what they change day to day.
Triple-pane acoustic laminated windows, insulated walls and ceilings between suites, and sealed entry doors keep the city and the neighbours out. The windows alone perform about 75% better than typical windows.*
Acoustically insulated dropped ceilings, about 70% better sound insulation*
Insulated walls between suites, more than 100% better*
Sealed entry doors with acoustic thresholds, about 80% better*
Extra insulation around bathrooms and laundry, about 75% better than uninsulated*
Solid-core suite doors, 40% thicker than typical*
Double glued-down cork underlayment below the floors
Each suite draws fresh air from outside rather than from the corridors, and built-in steam humidifiers hold humidity in the 40 to 60% range year-round.
Fresh make-up air drawn from outside, not from corridors
