Raptors president Masai Ujiri was reportedly involved in an altercation with a sheriff's deputy moments after Toronto defeated the Golden State Warriors for its first National Basketball Association championship in franchise history.
At the final buzzer they poured out into downtown Toronto's Yonge-Dundas Square chanting the team's rallying cry "We the North".
"I came to a team, a new coach, and that mindset was the same as mine".
"I wanted to make history here".
Leonard is the third player to win Finals MVP with two franchises, joining only Kareem Abdul-Jabbar and LeBron James.
With the win, Leonard becomes just the third player in National Basketball Association history to win the award with multiple teams.
One of the fans watching was Raptors superfan and rapper Drake.
It was a heartbreaking moment for a team that have had to deal with injury after injury in the playoffs.
Fireworks lit up the square as the crowd sang Queen's triumphal anthem "We Are the Champions", while others kissed, danced and shouted the team's name. Durant had missed roughly a month before that with a strained calf.
"It was a one-possession game to keep our season alive tonight", he said of the 114-110 loss.
"So really proud of the way that we fought until the end and this five-year run's been awesome, but definitely don't think it's over".
Golden State forward Green, who scored 11 points, said: "Everybody on this team played with a lot of heart".
