It was announced on April 19, 2005 the re-signing of Diplacido for the 2005 season.[8] Throughout the season the Lynx performed poorly and the team was stuck at the bottom of the table for the majority of the year, and eventually finished with a record of 3 wins, 17 losses, and 8 ties the worst performance in league and club history and a 12th-place finish. On August 1, 2005 he was transferred to the Montreal Impact along with Charles Gbeke in order to assist the Impacts' offence, which lost key players to European teams.[9] He played a key role in the midfield helping the Impact to a 15-game undefeated streak setting a new league record, while helping the team clinch the Regular Season title and claiming the Voyageurs Cup, but the Impact failed to defend their 2004 League title.
