NOTE: Due to recent changes to the Canadian Aviation Regulations and Standards associated with marking and lighting of obstacles the obstacle assessments form has changed. Appendix C of Standard 621 contains the new form for all future obstacle assessments. The Aeronautical assessment form for obstruction marking and lighting replaces the previously used Aeronautical Obstruction Clearance Form (AOCF). The old form can no longer be accepted due to the regulatory changes.
