This game was between sheet metal workers and carpenters at the Union Tournament in Vaughan, Ontario. It's not exactly clear what led to the brawl, but players started fighting while leaving the ice, presumably at the end of a period, or the game. The camera flips to another angle, and you see a player messing with someone not dressed in hockey equipment on the bench, while another from the opposing team runs the length of the bench and hits him in the head with a running punch.
As someone in the comments pointed out, it's never a good idea to take on someone in skates when you're only wearing shoes. As far as we know, no one received any major injuries in the skirmish.
