About 620 N LaSalle building

Previously home to the former Morrie Mages, Sportmart and Sports Authority, this iconic eight-story building at the corner of Ontario and LaSalle has been reinvented as a modern timber loft office building. The extensive inside and out renovation and modernization that included the  replacements of all mechanical systems, installation of new vertical transportation as well as new modern amenities such as a large roof top desk, showers, bike room, and tenant lounge areas. These new additions as well as many others not listed here have transformed the building into a state of the art work environment with convenient lifestyle amenities to meet today’s tenant demands.
