The Telus Tower is an office building at 630 René Lévesque Boulevard West in Montreal.
In 1960, Bunshaft had recently completed his seminal work, Lever House in New York City.
During the 1960s when Montreal's financial district shifted from its St. James Street center to midtown, The CIL House also became the annex headquarters of the Bank of Montreal when it added a main banking branch there.
Then-named Dorchester Boulevard West became the financial center of Montreal and Canada with the largest Canadian banks and insurance companies having a presence.
Today, it is home to the Montreal operations of Telus, the head office of Telus Health Solutions, but also houses the local offices of NEUF architect(e)s, Accenture, Roche, Canada Life, ROBIC, Clyde & Co, Fairstone Financial, Inc., as well as a Bank of Montreal branch.
