The league was formed in 1980 as a competition for corporations to enter teams made up of their employees. However, the league modified its rules in 2017 to an open player registration policy thereby allowing any adult to register for a team.

League President Tim Baigent explained the reasoning behind the change "Even though the NCISL is well known and respected in the Ottawa soccer community, the name no longer represents what our organization is. Our members recognized that this past move to an open player registration policy needs to be reflected in our identity if we are to grow as an organization."

Last year the NCISL operated a summer soccer season for adult recreational players with 45 teams participating in a 7v 7 league at the Richcraft Recreation Complex in Kanata.  However the league is currently planning a return to 11 v 11 soccer for the 2022 season.

All new teams are welcome to join our organization.
