The 2005 Montreal Alouettes finished second place in the East Division with a 10–8 record. This was a disappointing season, by Alouettes standards, but they made it to the Grey Cup the hard way. They hosted the East Semi-Final and defeated the Saskatchewan Roughriders at Olympic Stadium, 30–14. They then traveled to Toronto to face the Argonauts at the Skydome, and they won 33–17, to advance to the Grey Cup. After a hard fought game they lost to the Edmonton Eskimos, 38–35 in what was only the second ever Grey Cup to be won in overtime.
