Nepean was virtually a vacant lot for lacrosse until the 1990s, when locals applied for an expansion team in the OLA.

Unlike Mimico, which has seemed to carry rather average results every year, Nepean seems to have more of one extreme or the other.

This resulted in the team having three straight losing seasons, despite coming close to cracking .500 in 2006.

With the Ottawa Titans on a two-year leave of absence, the Knights 2008 season was big improvement with the team going 11-9 and having a strong showing in the playoffs against the Mimico Mountaineers.
