Justin Bieber is a real Canuck on the ol' ice rink ... coming razor close to dropping his gloves and taking on some hockey players who broke his stick and didn't say sorry.
The Biebs got in on a beer league pickup game at the Toyota Sports Center -- where the L.A. Kings practice -- and damn near came to blows after a dirty play.
Watch -- as #23 (Biebs) comes in for a shot, a defender comes down hard with his own stick and snaps Justin's in 2. Safe to say Justin didn't take kindly to that.
It definitely feels like a face-off.
