Place du Portage consists of four phases which were built in different stages during the 1970s and early 80s. The office complex was built in order to revitalize Hull's decaying downtown core and also to increase the proportion of the federal workforce in the overall National Capital Region. Although the installation of thousands of jobs in the Hull and Gatineau area has resulted in significant economic benefits to local businesses and the real estate market, some people feel that the complex has transformed downtown Hull in some negative ways. Much of the old downtown core was replaced with a series of massive towers and approximately 4,000 residents and businesses were displaced in the area that was once the town's main commercial area.
