Canadian Air Traffic Control Association

The Canadian Air Traffic Control Association (CATCA) is first and foremost a trade union representing all Air Traffic Controllers in Canada.

We are a local of Unifor. Our most important role is collective bargaining with Transport Canada, Serco, and NAV Canada.

We work closely with our members to understand their needs and are guided by their voice. Together we have achieved so much and will continue to strive for excellence in the workplace. More
