All-Star Game The 60th National Hockey League All-Star Game was an exhibition ice hockey game played on January 25, 2015. The game was held in Columbus, Ohio, at Nationwide Arena, home of the Columbus Blue Jackets. This was Columbus's first time hosting the NHL All-Star Game. This was originally scheduled to take place on January 27, 2013, in Columbus, Ohio. It was canceled as a result of the ongoing 2012–13 NHL lockout. There was no all-star game last season due to the 2014 Winter Olympics in Sochi, Russia. Postponed games The Toronto Maple Leafs–Ottawa Senators game originally scheduled for October 22 was postponed due to the 2014 shootings at Parliament Hill, Ottawa. The game was rescheduled for November 9. The New York Rangers–Buffalo Sabres game originally scheduled for November 21 was postponed due to the winter weather-related difficulties in the area. The game was rescheduled for February 20, 2015, displacing a Sabres home game with the Senators that was originally scheduled for the same day. That game was moved to December 15, 2014, as a result of the rescheduling of the Rangers–Sabres game.
