Merger and emergence as a league powerhouse (2003–2005) began his career with Glen Shields Sun Devils. In 2003, Glen Shields merged with the York Region Shooters and united the York Region territory under principal owner
Tony De Thomasis. The new additions added to the roster were Canadian international
Elvis Thomas,
Matthew Palleschi,
Cameron Medwin, and Jason De Thomasis. The merger proved a success as Vaughan recorded an eight-game undefeated streak and clinched the final playoff in their conference. In the first round they faced
Toronto Supra, where they defeated Supra with 4 goals to 3 with Wilson Hugo, Smith, Thomas, and Aundrea Rollins providing the goals. In the next round the Sun Devils faced Western Conference champions the

CPSL Championship. Their opponents in the finals were
Brampton Hitmen during the match Vaughan's Chris Turner was ejected from the match which gave Brampton the advantage to win the championship by a score of 1–0. Despite the defeat the merger ushered in a new era for the club in becoming a powerhouse within the CPSL. Several changes were made in 2004 as the club was renamed the Vaughan Shooters and transferred their home venue to the
Ontario Soccer Centre. Head coach Benning parted ways in order to accept a position with the
CSA, and Sam Mederios was named his successor. Vaughan also established an affiliation with two youth clubs Woodbridge Italia and Vaughan Soccer Club. For the second straight year the Shooters clinched the final playoff berth in their conference with the third best offensive and defensive record. In the preliminary round of the playoffs they faced the
Metro Lions and blitz them 5–3. The second round was a similar outcome where Vaughan defeat the Eastern Conference champions Toronto Supra 4–1. The championship finals featured Vaughan against Toronto Croatia, where the Shooters fell 4–0. In 2005,
Carmine Isacco was given head coach responsibilities and brought in
Saint Kitts and Nevis international
Darryl Gomez,
Stuart Black, and Brian Bowes. Throughout the season Vaughan consolidated their status as a powerhouse by claiming their first piece of silverware the Eastern Conference title. Vaughan achieved a team best by posting the best offensive and defensive record. As division champions they received an automatic bye to the semifinals, where they thrashed Toronto Croatia by a score of 4–0. In their third championship final appearance they faced the
Oakville Blue Devils, but once again fell short 2–1 in extra time. At the conclusion of the season the league honored Desmond Humphrey with the
CPSL MVP award, and Tony De Thomasis with the CPSL President award.
First championship and consistent playoff appearances (2006–2013) On September 15, 2005, the league announced the creation of the International Division for the 2006 season with Vaughan joining the division as Italia Shooters in order to represent and to celebrate the club's strong
Italian heritage. Further changes were made in the managerial office with team owner De Thomasis undertaking the coaching duties. Italia managed to acquire a postseason berth by finishing third in a highly competitive division. The club received some luck early on in the playoffs as they advanced to the next round by a forfeit from the Brampton Stallions. Their opponents in the semifinals were Toronto Croatia, and with a goal from Jason De Thomasis they reached the championship final for the fourth consecutive year. Their opposition were the International Division champions
Serbian White Eagles FC a team where the majority of players had European experience. During the match Italia performed the miracle needed at
Esther Shiner Stadium from a lone goal from
Anthony Adur to claim their first CSL Championship in a 1–0 victory. De Thomasis was recognized with the CSL Coach of the Year award. For the 2007 season Italia finished third in their division with the third best offensive record, and maintained the best defensive record. Unfortunately Italia failed to defend their championship after losing 3–0 to
Trois-Rivières Attak in the first round of the playoffs. In preparations for the coming 2008 season the club hired Vito Colanglo as general manager and moved their home venue to Joan of Arc Turf Field. The organization also reached an agreement with the
Toronto Lynx of the

Murphy Wiredu,
Jon Paul Piques, and Richard Asante. The additions paid off as Italia secured their second division title and had the best offensive record. In the quarterfinals the Shooters defeated
Brampton Lions FC 1–0. Their playoff run came to a conclusion in the next round against Serbia, where the White Eagles defeated them 3–0. In 2009, Woodbridge S.C., and Unionville S.C. became associated with Italia and operated as the club's reserve teams in the CSL Reserve Division. In the regular season the Shooters had a mediocre season, but still managed to clinch a postseason berth by finishing third in their division. In the postseason Italia revived their team performance by defeating St. Catharines in a two-game series with 7–1 goals on aggregate. In the next round they faced the National Division champions Trois-Rivieres where in both games they tied the series 4–4 on aggregate with the Attak scoring the winning goal in overtime. The CSL administration restructured the league by combining both divisions to form the CSL First Division. As a result of the changes the club changed its name to York Region Shooters, reflecting the previous merger in 2003 and the larger area of
