Allen's Argonaut re-debut was a 20-18 season- opening loss to the Saskatchewan Roughriders that also marked Allen's 300th regular season game of his CFL career. In Week 7, Allen became only the third quarterback in professional football history to pass for 60,000 yards against his former club, the BC Lions.

In Week 9 of the 2004 season versus Montreal, Allen exited the game in the third quarter with a fractured left tibia, and spent Weeks 10-16 on the injured reserve roster.

Allen continued his assault on the record books during the 2005 CFL season. On October 27, 2005, Damon reached the 5,000-yard passing plateau for the first time in his 21-year CFL career by posting a 34-11 victory against the Hamilton Tiger-Cats. The win guaranteed Toronto a first-place finish in the CFL East plus home field advantage in the playoffs. The game took place before 40,085 fans; the largest crowd for a CFL game in Toronto since 1992. However, the Argonauts were defeated 33-17 in the 2005 East Final by the Montreal Alouettes, thereby thwarting their hopes of repeating their 2004 Grey Cup win.
In 2005, Allen won his first CFL's Outstanding Player Award. In that year, he also hosted the inaugural "Damon Allen Quarterback Challenge" which featured top CFL quarterbacks participating in various skill competitions. In the Quarterback Challenge's second year, Allen won the event.
In 2006, Allen started the opening home game of the season against the Hamilton Tiger-Cats and broke the middle finger on his right hand on Toronto's third play.

Allen missed nearly a month and a half of action with a broken finger, returning on July 29 vs. the BC Lions.
On September 4, 2006, at the Labour Day Classic against the Hamilton Tiger-Cats, Allen broke Warren Moon's record (70,553 yards) to become professional football's all-time passing leader. The record-setting completion, a 29-yard shovel pass to wide receiver Arland Bruce III, took place at 5:02 of the third quarter. The game was suspended briefly for a presentation by CFL Commissioner Tom Wright.

On February 28, 2007 Allen re-signed a contract with the Argonauts for one year plus an option .
Allen started the 2007 season as the Argos starting quarterback beating out Michael Bishop and former NFL starter Mike McMahon. However, he was replaced in the third quarter of the first game by Bishop despite having gone 14-18, 130 yards and a touchdown. Allen was then bumped down to third on the depth chart. However, after Bishop went down with a wrist injury and McMahon failed to impress, Allen stepped into the starting role once again. However, in his first game back as starter he injured his toe. Allen was placed on the nine-game injured list and Rocky Butler took over as the Argos starting quarterback
Allen announced that his retirement as a player on May 28, 2008, but will stay with the Argos as a special advisor to CEO Pinball Clemons.
