In the championship final, "Le Manic" and the Rowdies battled back and forth into double overtime at the Montreal Forum.

Tampa Bay continued to trail for most of the fourth until Zequinha tied the match with 1:55 remaining to send it to sudden death overtime.

The first extra session failed to produce a golden goal, but with just under two minutes lapsed in the second overtime Mark Karpun beat his defender down the left wing.

He then tucked a shot past Manic goalie, Mehdi Cerbah, inside the far post for the game winner and the Rowdies' third indoor trophy.

In that event, goalie Jürgen Stars stopped all five Strikers' shots, while Wes McLeod and Hugo Perez converted their attempts for a 2–0 victory.

Goalkeeper, Tom Boric was lost for the remainder of the indoor season after a knee injury in the Rowdies' second grand prix match on January 22.

The February try-outs for Team America overlapped with the Grand Prix schedule and as a result Arnie Mausser, Pedro DeBrito, Perry Van der Beck and Glenn Myernick became unavailable to the Rowdies for several games including the semifinal and championship matches.

[18] Finally, in-state rival, Fort Lauderdale, met Tampa Bay at the Lakeland Civic Center in a post-tournament fixture, to close out the Rowdies' abbreviated 1983 indoor campaign.
