McLaughlin Building, built in the Gothic Revival style, was one of the first automobile dealerships in Toronto.

It later became Canada's largest Cadillac dealership,[4] and by the 1980s was operated by former Member of Parliament John Hollings Addison.

[7][2] The latter designation required any property owner to apply to the City of Toronto prior to making changes or demolishing its historic elements.

[9] Because of the soft soil at the site, and to facilitate excavation, the historic facade was dismantled and stored off-site during construction of the seven-floor underground garage.

After the garage and foundation appropriate for the fifty floors above ground were completed, the facade was reconstructed, incorporating the important heritage components.
