That changed under the leadership of former head coach, Danny Maciocia, in 2014, as the Carabins defeated the Laval Rouge et Or to win their first Dunsmore Cup.

The team then won the national semi-final Uteck Bowl against the Manitoba Bisons to qualify for the first Vanier Cup game in program history.

In the 50th Vanier Cup, the Carabins defeated the McMaster Marauders by a score of 20–19 to win the first national championship in program history.

Maciocia resigned following the 2019 season to join the Canadian Football League's Montreal Alouettes and was replaced by Marco Iadeluca on February 11, 2020.

To cap off the successful campaign, which had already crowned Montreal quarterback Jonathan Sénécal with the HEC Creighton Trophy for the most outstanding player and the Presidents' Trophy for the most outstanding defensive player, Harold Miessan, the Carabins won their second Vanier Cup title, defeating the UBC Thunderbirds 16-9 in the 58th Vanier Cup.

During their four playoff games, Montreal did not concede a single touchdown and finished with an impressive combined score of 111-21.
