Joint Canada–U.S. CIRVIS Reporting Framework for Urgent Security Sightings
A joint Canada–United States framework mandates urgent reporting of sightings vital to security across civil, commercial, government, and military operators—aircraft, vessels, fishing boats, and installations—allowing rapid defensive or investigative action, with mandatory reports for hostile or unidentified aircraft or formations, missiles, UFOs, hostile or unidentified submarines, groups of military surface vessels, or unusual activity, reported airborne or post-landing if transmission is not possible, including cases at unlisted fields or stations; reports must follow the CIRVIS format detailing observer identity, object description (shape, size, color, formation, features, tail/exhaust), flight path and maneuvers, disappearance, visibility duration, and manner of observation, time/date in Zulu, precise observer coordinates, weather and winds aloft, ceiling, visibility, cloud cover, atmospheric/astronomical data, interception actions, and physical evidence, with airborne reporting also providing aircraft type, identification number, altitude, heading, speed, and home station, and post-landing reports may include photographs.
