They refer to it as the "Winter Classic" for young hockey players in Kitchener.
The city hosts its annual Hockeytown event on Saturday at city hall.
Kitchener Minor Hockey (tyke players) will compete on the outdoor rink for a chance to win the Mayor's Cup.
There will also be a charity BBQ and inflatable play areas inside the rotunda.
