The Calgary Flames and Edmonton Oilers will play in the 2023 Tim Hortons NHL Heritage Classic at Commonwealth Stadium on October 29. The 7th Heritage Classic will return to Commonwealth Stadium for the 20th anniversary of the first NHL regular-season outdoor game, the 2003 NHL Heritage Classic, a 4-3 win for the Montreal Canadiens over the Oilers in front of 57,167 fans on November 22, 2003. Including that game, there have been 35 regular season outdoor games played to date, attended by 1,755,438 fans.
"To play an outdoor game in Edmonton, at Commonwealth, to play Calgary on the 20th anniversary of the last one, super special," Oilers captain Connor McDavid said.
