CANSO also represents its members' views in regulatory and industry forums, including at the International Civil Aviation Organization (ICAO), where it has official observer status.

[citation needed] Full membership is open to all ANSPs regardless of their legal status.

The associate membership of CANSO is drawn from companies and organisations from the aviation industry who are involved with the delivery of air traffic services.

Membership offers them the chance to network both formally and informally with clients, and decision makers across the aviation industry.

Associate members may contribute to CANSO's work programmes and help it improve the delivery of air navigation services.
