As is the case with small town hockey across Canada, he said, the arena is not just a recreation facility, but a focus of community life with the hockey team at its center.
Police say the 14 who survived the crash have varying degrees of injury, some critical.
The team was on its way to play in Game 5 of a semi-final against the Nipawin Hawks.
Team President Kevin Garinger said parents from across western Canada were struggling to cope with the tragedy and were rushing to the scene.
Darren Opp, the president of the Hawks, told the Globe and Mail: "It's a disgusting accident, my God, it's very, very bad".
"It's a disgusting accident, my God", Opp said. He is said to have been provided "mental health and wellness assistance".
The names of the dead and injured have not been released by police, but some have been confirmed by family members and others. "It's too early to comment on the cause of the collision".
So far, a number of victims have been named by family and friends including head coach Darcy Haugan, team captain Logan Schatz, 20, radio announcer Tyler Bieber, Stephen Wack, 21, Jaxon Joseph, 20, Logan Hunter, 18 and 16-year-old Adam Herold.
Many social media users posted Haugan's photograph alongside messages of shock and sympathy, and the hashtags #prayersforhumboldt and #humboldtstrong. "We've become like a family and try to help each other".
"It's just gut-wrenching. It tears your heart out to think that these are fine young guys, that their futures have been wiped out", said one local, Gordon Lees, who has been a fan of the team since it was formed in 1970 when he was ten years old.
"It's overwhelming. It's been tough on everybody", Muench said.
Condolences poured in from current and former hockey players, sports organizations and political leaders.
"I can not imagine what these parents are going through, and my heart goes out to everyone affected by this bad tragedy, in the Humboldt community and beyond", Trudeau tweeted.
"The worldwide ice hockey community extends its sincerest condolences to the families and friends of those involved", IIHF president Rene Fasel said in a statement. "May God be with them all!"
"I can't imagine being the parent or the wife or the kids at home going through something like this", Toronto Maple Leafs coach Mike Babcock said at a press conference.
"We've had a lot of young men go through the house. It's a awful thing that happened". You are invited to gather for a prayer vigil at our place Sunday night (April 8th).
"Our thoughts are with the players, families, coaches, team management, and all those throughout the community who have been affected by the tragedy, involving the Humboldt Broncos hockey team", Bettman wrote.
Grant Merriman, president of the La Ronge Ice Wolves and bus driver for the team, said he has driven his players by the intersection of highways 335 and 35 many times. "It's just unfathomable for those families", she said Saturday morning.
