On December 2, 2008 the Montreal Impact announced the re-signing of central defenders Pizzolitto and Stefano Pesoli to a two-year contract. During the 2009 season he helped the Impact maintain the second best defense in the league, by only allowing in 28 goals in 30 games. On June 28, 2008 he reached a milestone with the club by playing his 220th career match, surpassing Nick De Santis for second spot in club history. In the Nutrilite Canadian Championship, he helped win the 2008 Nutrilite Canadian Championship for the Impact which meant the club qualified to the inaugural CONCACAF Champions League. During the Impact tenure in the Champions League, Pizzolitto played a dominant role in the defence for the Impact throughout the tournament. In total he appeared in nine out of ten matches and helped the Impact reach the quarterfinals before losing out to Santos Laguna to 5–4 on aggregate. He was selected to the USL First Division First All-League team for the first time in his career, and was awarded by Montreal the "Defensive Player of the Year award" for the second time in his career.
