Montreal Olympic Stadium, Montreal

Montreal's Olympic Stadium, constructed in the mid-1970s as the primary location for the 1976 Summer Olympics, is a versatile facility. Famously known as "The Big O," it derives its nickname from both its name and the distinctive shape of its roof, resembling a doughnut. Additionally, it is sometimes referred to as "The Big Owe" due to the exorbitant cost associated with its construction and the entire 1976 Olympics.

This stadium is Canada's largest with seating capacity. After the Olympics, it was transformed into the home ground for Montreal's pro baseball and football teams. The Montreal Alouettes of the CFL moved to Molson Stadium in 1998 for regular season games but Olympic Stadium still hosted playoffs and the Grey Cup until 2014. In 2004, the Expos relocated to Washington, D.C. and became the Washington Nationals.

Presently, the stadium serves as a multipurpose venue for special events like concerts and trade shows. Its permanent seating capacity stands at 56,040, but it can be expanded using temporary seating. Occasionally, the Montreal Impact of Major League Soccer (MLS) utilizes the stadium when ticket demand justifies its large capacity or when inclement weather hampers outdoor play at nearby Saputo Stadium during the spring months.

Nestled within the northern base of the stadium is the Montreal Tower, an inclined tower that holds the distinction of being the world's tallest at a height of 175 meters (574 feet).
