Question: The 2012 Vanier Cup took place at a stadium opened in what year?
Context: The 2015 Vanier Cup, the 51st edition of the Canadian university football championship took place on Saturday, November 28, 2015 at Telus Stadium in Quebec City, Quebec.  It was the fourth time that the city of Quebec has hosted the Vanier Cup.  For the third consecutive year the championship game was played in the province of Quebec.  The game featured the Canada West Champion UBC Thunderbirds and the RSEQ Champion Montreal Carabins.  This was the second appearance for the Carabins and the sixth for the Thunderbirds. The 2016 Vanier Cup, the 52nd edition of the Canadian university football championship, took place on Saturday, November 26, 2016 at Tim Hortons Field in Hamilton, Ontario.  This was the fourth time that the city of Hamilton had hosted the Vanier Cup, which will host in 2017 as well.  The RSEQ Champion Laval Rouge et Or defeated the Canada West Champion Calgary Dinos by a score of 31-26.  This was the tenth appearance in the Vanier Cup game for both programs, with Laval having now won nine titles and Calgary four. The 2012 Vanier Cup, the 48th edition of the Canadian university football championship, took place on Friday, November 23, 2012 at Rogers Centre in Toronto.  The game featured a rematch of the previous year's Vanier Cup game as the McMaster Marauders attempted to become repeat champions against the Laval Rouge et Or.  This was the second time (after 1976-1977) in Vanier Cup history that the same two teams played each other in consecutive years.  The Vanier Cup was played on the same weekend it hosted the 100th Grey Cup and was part of the week-long festivities that were planned for the event.  This marked the second consecutive year that the two games were played in the same city on the same weekend; after the 47th Vanier Cup and 99th Grey Cup were played in Vancouver. The 46th Vanier Cup took place on November 27, 2010, at PEPS Stadium in Quebec City, Quebec, determining the CIS Football champions for 2010.  The Laval Rouge et Or defeated the Calgary Dinos 29–2 to win their sixth national title in twelve years.  Including the playoffs, the Rouge et Or won thirteen games, a single season record.  Laval's defence held Calgary to 147 yards on offence; the Dinos' only points came on a conceded safety in the second quarter. The 24th Vanier Cup was played on November 19, 1988, at Varsity Stadium in Toronto, Ontario, and decided the CIAU football champion for the 1988 season.  The Calgary Dinos won their third championship by defeating the Saint Mary's Huskies by a score of 52-23.  This was the last Vanier Cup game to be played at Varsity Stadium as the championship would be played at the new SkyDome the following year. The 2011 Vanier Cup, the 47th edition of the Canadian university football championship, took place on Friday, November 25, 2011 at BC Place in Vancouver.  The McMaster Marauders defeated the Laval Rouge et Or 41-38 in only the second ever Vanier Cup to go into overtime.  The Marauders won their first ever national championship while the Rouge et Or lost a Vanier Cup game for the first time.  BC Place underwent a renovation, including a retractable roof, and hosted the Vanier Cup on the same weekend it hosted the Grey Cup.  This marked the first time the two games were played at the same venue on the same weekend since 2007.  This Vanier Cup is notable for being considered one of the best Canadian football games ever played. The 2014 Vanier Cup, the 50th edition of the Canadian university football championship, took place on Saturday, November 29, 2014 at Molson Stadium in Montreal, Quebec.  It featured the OUA champion McMaster Marauders and the RSEQ champion Montréal Carabins.  This was the first appearance for the Carabins and the fourth for the Marauders.  It was the first time that the city of Montreal hosted the Vanier Cup and it was organized by the Canadian Football League's Montreal Alouettes as opposed to a member CIS club.  For the second consecutive year the championship game was played in the province of Quebec. The 13th Vanier Cup was played on November 19, 1977, at Varsity Stadium in Toronto, Ontario, and decided the CIAU football champion for the 1977 season.  The Western Ontario Mustangs won their second consecutive championship and fourth overall by defeating the Acadia Axemen by a score of 48-15 in a rematch of the previous year's game.  This was the first, and so far only, time that the same two teams played in a Vanier Cup game in consecutive years. Rogers Centre, originally named SkyDome, is a multi-purpose stadium in Downtown Toronto, Ontario, Canada, situated just southwest of the CN Tower near the northern shore of Lake Ontario.  Opened in 1989 on the former Railway Lands, it is home to the Toronto Blue Jays of Major League Baseball (MLB).  Previously, the stadium served as home to the Toronto Argonauts of the Canadian Football League (CFL) and the Toronto Raptors of the National Basketball Association (NBA).  The Buffalo Bills of the National Football League (NFL) played an annual game at the stadium as part of the Bills Toronto Series from 2008 to 2013.  While it is primarily a sports venue, it also hosts other large-scale events such as conventions, trade fairs, concerts, travelling carnivals, and monster truck shows. The 2013 Vanier Cup, the 49th edition of the Canadian university football championship, took place on Saturday, November 23, 2013 at TELUS-Université Laval Stadium in Quebec City, Quebec.  This was the third time in five years that Université Laval hosted the Vanier Cup.  For the previous two years, the game had been held in conjunction with the Canadian Football League's championship, the Grey Cup, but due to logistical issues by this year's host, Regina, a joint venture was not possible.
