Number one seed Laval Rouge et Or face second-seeded McMaster Marauders for gold later Sunday.
Neither school has won the Bronze Baby. The Marauders are making its debut in the final, while the Rouge et Or finished runner-up to the McGill Martlets at the 2017 national tournament.
The Huskies raced out to a 19-12 lead to end the first quarter, then went ahead by 19 in the second before taking a 41-27 advantage into the halftime break.
But the Gee-Gees battled back in the third, and took a 48-47 lead into the fourth quarter.
The Gee-Gees went up by seven points in the fourth before Dukate connected from three-point range to pull the Huskies to within a point twice in the final three minutes. A shot by Masikewich bounced off the rim at the final buzzer.
