Desjardins Group is a massive financial cooperative specializing in credit unions and insurance. In 1970, they spearheaded one of Montreal’s largest real estate development projects. Over 12,000 workers spent nearly six years building Complexe Desjardins. The result was almost four million square feet of office space in three connected high-rises. The South Tower is the tallest at 499 feet. At the base is a shopping mall with more than 100 retailers plus restaurants and a food court.
