A 13-yard touchdown pass from QB Zach Collaros to receiver Darvin Adams during the Bombers first possession of extra time was the difference.
Winnipeg would seal the victory when a Jeremiah Masoli pass was intercepted by linebacker Kyrie Wilson on the next possession.
Masoli came on in the second quarter after starting Ticats quarterback Dane Evans went down.
Evans left with 7:10 remaining in the first half after going down under two Blue Bombers. He had narrowly escaped Willie Jefferson earlier on the play with the Winnipeg defensive end penalized for his hand connecting with the quarterback’s head.
The Ticats had a 12 point lead mid-way through the third quarter before Collaros hit WR Nick Demski on a 29 year pass with kicker Sergio Castillo later hitting a field goal with just over two minutes left.
Kicker Mike Domagala tied the game with just seconds left from 13 yards to send the game to a fifth period.
Collaros completed 21 of 32 passes for 240 yards and two touchdowns. He was voted the 2021 Grey Cup MVP.
Masoli was 20 for 25 with 185 yards passing and a pair of touchdowns. Evans completed just four passes for 24 yards before bowing out of the game.
The top rusher was the Bombers Andrew Harris who picked up 80 yards on 18 carries.
Castillo hit for four field goals, while the Ticats Domagala had three.
The two clubs met Sunday night in the Hamilton’s Tim Hortons Field, marking the first time since 1996 that the CFL’s title game was held in Steeltown.
Winnipeg registered a league-best 11-3 record, scored the most points and allowed the fewest in 2021, while Hamilton had an up and down season, finishing 8-6 while dealing with a number of injuries.
Since 1972, which is the last time Hamilton won the cup while playing on home turf, home teams playing in the Grey Cup are 6-6.
The Ticats now have the longest CFL championship draught. They’ve not won since their 1999 victory in Vancouver – 32–21 over the Calgary Stampeders.
