Policy on the Protection and Use of Witness Statements

Effective September 30, 2018

1. Context

1.1 The TSB aims to advance transportation safety by conducting independent safety investigations. The effectiveness of those investigations is dependent, in part, on gathering witness statements.

1.2 In order to encourage witnesses to provide open and frank details without fear of reprisal or any negative repercussions, section 30 of the Canadian Transportation Accident Investigation and Safety Board Act (CTAISB Act) declares that statements and the identity of their authors are privileged. The CTAISB Act also states that no person shall knowingly communicate a statement or permit it to be communicated to any person except as provided by this Act or as authorized in writing by the person who made the statement.

2. Definitions

2.1 The term “statement,” as defined in the CTAISB Act, should be interpreted broadly. A statement includes

  1. an oral, written, or recorded declaration relating to a TSB investigation and given to the TSB or any person acting for the TSB (first responder, foreign-language interpreter, etc.),
  2. a transcription or summary of a declaration referred to above,
  3. notes taken by an investigator when speaking with a witness, or
  4. other information received by the TSB that could reasonably be taken to be intended as a statement, such as communications that convey technical information requested by the TSB as part of its investigation.

2.2 “Witness” means any person who can provide information about an occurrence or the particular operating context in which the occurrence took place. This can include crew members, passengers, eyewitnesses on site, controllers, managers, maintenance personnel, or others.

3. Policy objective

3.1 The purpose of this policy is to describe the TSB’s approach to the protection of witness statements that it collects, the use of witness information in investigation reports, and the release of witness statements where appropriate.

4. Policy requirements

4.1 Identity of witnesses

4.1.1 The names and identities of all witnesses and their witness statements are privileged and will not be released by the TSB unless the witness agrees in writing or the TSB is ordered to do so by a court.

4.2 Use of witness information in TSB reports

4.2.1 In its reports, the Board will attempt to use wording that does not enable the identification of a witness.

4.2.2 Generally, direct references to or quotes from witness statements will not be used in TSB reports or communication products.

4.2.3 In exceptional cases, where witness information is essential to support a Board finding, and there is no way to convey the required information without providing details that may lead to the identification of a witness, the Board may include such information in its reports if it is necessary in the interests of transportation safety.

4.3 Release of witness statements

4.3.1 Upon written request, a witness will be provided a copy of his or her statement.

4.3.2 If a third party representing the witness requests in writing a copy of the statement, the witness will be informed by the TSB and a copy will be sent only to the witness for transmittal to the third party.

4.3.3 If police or another investigating body asks for copies of statements, the TSB will contact the witness directly to ask whether he or she consents to the release of the statement. The consent must be provided in writing. The TSB does not accept consent obtained by others.

4.3.4 If the TSB receives an Access to Information request for a copy of a witness statement, the TSB will inform the witness of the request and ask whether he or she consents to the release of the statement. The consent must be provided in writing. If the witness does not consent to the release, the TSB will continue to protect the privilege given to his or her statement and will not release the information.

4.3.5 Requests for release of witness statements in any legal proceedings will always be opposed by the TSB. If a court orders the production of witness statements, the TSB will request confidentiality orders restricting the use of these statements.

4.3.6 The TSB will inform a witness in any case where his or her statement is being released, together with the circumstances of the release.

5. Authorities

5.2 This policy will be reviewed and may be updated in response to changes in legislation, government priorities, or TSB strategic direction, but at least once every 5 years.
