A partnership between the Alouettes, the City of Montreal and province agreed to a long standing Phase II proposal to expand Percival Molson Stadium. Construction began in November, 2009 and was completed by the kick-off of the 2010 season. An additional 5,000 seats were added in south-side upper deck and east end zone additions to bring capacity to 25,012 seats.
While Molson Stadium gets rave reviews, the Alouettes also have at their disposal Olympic Stadium, which was the sole home to Montreal teams from from 1976 to 1987 and 1996 to 1998. Since moving into Percival Molson Memorial Stadium, the Alouettes have used Olympic stadium for special games, playoff games and Grey Cups. The last playoff game held in Olympic Stadium was 2012, the last Grey Cup held there was 2008 and the last regular season game held there was 2007. Quebecers are currently being asked for ideas on Olympic Stadium’s future.
In 2013, it was revealed the Fibreglass roof is deteriorating rapidly with over 3,000 small tears in the fabric in the 2013 fiscal year ending Oct. 31. The safety of the roof in times with the potential for snow or freezing rain has limited the events that can be held at the stadium, affecting plans for Montreal’s 375th anniversary and hosting the Grey Cup in 2017. In Sept., the Alouettes announced if they hosted a home playoff game, it would be at Percival Molson Memorial Stadium due to concerns over snow and Olympic Stadium. Ultimately, the Alouettes did not qualify for a home playoff game. The future of the stadium is under much debate in Montreal and the province, with demolition a possibility and a popular choice amongst a public who wishes to end the cost of the stadium on the taxpayer.
