Construction of the new John Molson Building (MB), the home of the John Molson School of Business located on the corner of Guy Street and De Maisonneuve Boulevard West, began in February 2007. At a ceremony at Concordia on October 30, 2006, the Quebec Minister of Education, Recreation and Sports, Jean-Marc Fournier, announced an investment of $60 million towards the construction of the new building. The government's $60 million represented about half of the total construction costs. Construction started on January 22, 2006, and the building was completed and opened in September 2009. The 15-story building now houses the Joh n Molson School's 9,200 full- and part-time students under the same roof for the very first time. The departments of contemporary dance, theatre and music also moved into the new MB Building. It is connected to the EV Building by a tunnel under Guy Street.
