Report an incident affecting airport or aerodrome safety

This page tells you how to report an incident that affects (or could affect) airport or aerodrome safety.

If a serious accident or incident has happened, report it as soon as possible to the Transportation Safety Board (TSB) for investigation.

For how to report aircraft-related incidents — including structural or mechanical problems — see Report a problem with aircraft airworthiness.

When are you required to report?

If you are a pilot, crew member, or air traffic controller, you must report serious aviation incidents to the Transportation Safety Board. This is a requirement under the Transportation Safety Board Regulations. Serious incidents include:

  • death or injury
  • missing aircraft
  • major structural problems with aircraft
  • collision

It is not mandatory to report serious incidents or accidents to Transport Canada. However, we strongly encourage airport and aerodrome operators to report critical events using our Civil Aviation Daily Occurrence Reporting System (CADORS).
