It was Hamilton’s first game of the Ontario Hockey League season and marked the first time the team played a meaningful game since the club lost in the Memorial Cup final in June.
Morrison’s first goal of Friday night’s game gave the Dogs a 2-1 lead in the first period after teammate George Diaco opened the scoring 9:08 into the game at Sleeman Centre.
Diaco added his second goal of the game late in the second frame to give Hamilton a commanding 4-1 lead.
But the Storm fought back and tied the game with 3:26 to play in regulation time.
Morrison’s OT winner came on Hamilton’s eighth power-play of the game, in which the Bulldogs capitalized three times.
Matteo Drobac started in goal for Hamilton and made 29 saves in the win.
The Bulldogs travel to Peterborough Saturday night.
