Transport Canada collects aviation occurrence information through CADORS. The purpose of the system is to provide initial information on occurrences involving any Canadian-registered aircraft as well as events which occur at Canadian airports, in Canadian sovereign airspace, or international airspace for which Canada has accepted responsibility that includes events involving foreign registered aircraft.

Transport Canada endeavours to ensure the accuracy and integrity of the data contained within CADORS, however, the information within should be treated as preliminary, unsubstantiated and subject to change.

The Transportation Safety Board of Canada is the official source of aviation accident and incident data in Canada.
