TORONTO - Across the NHL on Saturday, teams paid tribute to victims of the attacks in Paris with moments of silence and other nods to France.
In Ottawa, Boston and Raleigh, N.C., the French national anthem, "La Marseillaise," was played before the game.
In Toronto, anthem singer Mason Greer sang "O Canada" entirely in French, a rarity for Maple Leafs games at Air Canada Centre.
A moment of silence was held before each game, often accompanied by the blue-white-and-red French flag and other Parisian symbols.
The NHL currently has two French-born players, Pierre-Edouard Bellemare of the Philadelphia Flyers and Antoine Roussel of the Dallas Stars.
Bellemare wore a decal of the French flag on his helmet for the Flyers' game at the Carolina Hurricanes, his return to the lineup after missing eight games with a lower-body injury.
The 30-year-old from Paris told reporters in Raleigh that "you don't expect those things to happen. It's terrible."
At least 129 people were killed in gun and bomb attacks across Paris on Friday night.
The NHL reportedly sent a memo to each of its 30 clubs instructing them to have heightened security measures in light of the attacks.
For the first time this season, the NHL has mandated metal detectors for fans, employees and players.
"Our primary goal, and I'm sure it's at all of the sports leagues too, is to have the safest environment possible for our fans, our team members, our players, everyone," NHL director of security Dennis Cunningham said in a phone interview prior to the season.
The Wall Street Journal reported one suicide bomber in Paris tried to enter a stadium where a soccer match was happening, but a security guard discovered he was wearing explosives.
