The building features an additional 51,000 square metres (550,000 sq ft) of office space on the upper levels, branded as "1500 University."

A bronze statue of hockey player Ken Dryden and a three-storeys-tall tableau made by fine arts enamel painter Bernard Séguin Poirier are located in the mall.

Cadillac Fairview ceded the Montreal Eaton Centre in exchange for Ivanhoe's stakes in Carrefour Laval and Promenades Saint-Bruno.

[8] The building at 677 Saint Catherine Street West was originally three storeys tall, and was built for the Goodwin's department store in the early 1900s.

After considerable redevelopment work between 2000 and 2002, involving the total gutting and complete redesign/rebuilding of the interior (preserving only the exterior facade and parts of the 9th floor), the former flagship of the Montreal retail scene was transformed into the building known as Complexe Les Ailes and 1500 University.

[9] For over a decade, the new mall was named after the Les Ailes de la Mode department store which occupied a third of its total area and was its main retailer.

In 2019, Les Ailes' former store space was taken over by Decathlon, which today is one of the largest tenants of the now merged Montreal Eaton Centre.
