The Montreal 1976 Summer Olympics were successful, but construction problems and corruption created a massive financial burden for citizens. At the opening, the tower and the retractable roof were incomplete. The tower was completed years later but the retractable roof was never completed as originally planned by Taillibert. Anglo locals refer to the stadium as the "Big O" due to its shape, but also as the "Big Owe" — a reference to the Olympic Park's exorbitant total cost, which was only paid off thirty years later with the help of a special tobacco tax.
