A crash between a transport truck and a bus carrying a junior hockey team in Western Canada left multiple people dead and others seriously injured, Canadian police said late on Friday.
"Our thoughts and prayers are with the families tonight", he said.
The identities of the dead have not yet been released by officials.
"This is much bigger than anyone can begin to imagine", Broncos team president Kevin Garinger told the Canadian broadcaster CBC.
The Winnipeg Jets and Chicago Blackhawks honoured the Humboldt team by wearing jerseys with the word BRONCOS across their name plates during their regular-season finale at Bell MTS Place Saturday night.
The team was on its way to play in Game 5 of a semi-final playoff game against the Nipawin Hawks. There was a moment of silence at the time the game was supposed to start.
"I can not imagine what these parents are going through, and my heart goes out to everyone affected by this awful tragedy, in the Humboldt community and beyond", Canadian Prime Minister Justin Trudeau tweeted.
Trudeau visited survivors of the crash in a Saskatoon hospital earlier in the day. Jordan Seipp, a friend, also confirmed his death. This included 21-year-old defenceman Stephen Wack, who was killed.
"They didn't know what to do", Humboldt Mayor Rob Muench told the newspaper. "You are losing your son and I think those have long lasting impacts".
"He loved those boys".
"He was just a hardworking guy", said Jackson Ross. "He didn't want to make any changes because they are such a great group of kids".
Opp, the president of the Hawks, said the coaching staff and players from their team were waiting to help.
The Los Angeles Kings also announced that they will donate the proceeds from their Saturday night raffle to those affected by the crash.
In an interview, he described his colleague, Mark Cross, as one of the happiest people he had ever met.
With players staying with local families, working in city businesses and attending local schools, the tragedy touches every corner of Humboldt, MacLEAN said. Bus driver Glen Doerksen and stats keeper Brody Hinz, who was 18, were also killed.
Adam Harold, a few days shy of his 17th birthday, was the youngest to die in the crash. The Saskatchewan league is a feeder system for higher levels of hockey with many graduating to play at USA and Canadian colleges and major junior league level, while some go on to the National Hockey League. "Best friends, teammates, allies, brothers", he wrote.
"Hockey was what brought us all together and we had two communities that were rivals in the rink". A family member posted on Facebook that her heart is broken.
Police said a lot of issues have to be investigated in the bus crash, including weather conditions at the time and any mechanical issues with the vehicles.
Ice hockey teams around the world expressed shock and paid tribute to the Broncos.
RCMP officers from Nipawin, Sask., stopped to lay flowers there on behalf of the detachment.
The crash sent shock waves of grief through the team's small hometown and a country united by the national sport.
While the wreckage had been removed, there were still playing cards and a broken DVD of the movie "Slap Shot" scattered in the ditch. "We offer our heartfelt condolences to Pittsburgh Penguins alumnus Chris Joseph, whose son, Jaxon, was among those who tragically passed away in the Humboldt Broncos bus accident".
