Olympic Stadium (Montreal)

Olympic Stadium is a multi-purpose stadium in Montreal, Canada, located at Olympic Park in the Hochelaga-Maisonneuve district of the city. Built in the mid-1970s as the main venue for the 1976 Summer Olympics, it is nicknamed "The Big O", a reference to both its name and to the doughnut-shape of the permanent component of the stadium's roof. It is also disparagingly referred to as "The Big Owe" in reference to the high cost of its construction and of hosting the 1976 Olympics as a whole.
