In 2009, the stadium received approval to remain open in the winter, provided weather conditions are favourable. However, the Olympic Installations Board issued a report stating that the roof was unsafe during heavy rainfall or more than of snow, and that it rips 50 to 60 times a year. The city fire department warned in August 2009 that without corrective measures, including a new roof, it may order the stadium closed. Events cannot be held if more than of snow are predicted 24 hours in advance, such as caused postponement of the Montreal Impact home opener soccer match in March 2014. A contract for a new permanent steel roof was awarded in 2004, with an estimated $300 million price tag. In June 2010, the Olympic Installations Board sought approval from the provincial government for the contract.
