In 1979, by formal agreement, the Canadian Coast Guard and the United States Coast Guard established the Co-operative Vessel Traffic Services (CVTS) for the Strait of Juan de Fuca region. The purpose of this agreement is to provide for a co-operative system of vessel traffic management in the applicable waters in order to enhance safe and expeditious movement of vessel traffic while minimizing the risk of pollution of the marine environment.
Participation with Prince Rupert, Seattle and Victoria Traffic is mandatory within Canadian and United States territorial waters. The CVTS Area of Operation is defined as 124°40W south along the Washington coast to 48°00N then west to 125°15W and north to 48°35’45”N. Inbound vessels are to check in with Prince Rupert Traffic on VHF Channel 74 (156.725 MHz) at either 48°00N or 125°15W prior to entering the traffic separation scheme. An information service such as a vessel’s identity, destination, or other information obtained through the VTS reports and sensors, is available upon request outside of the VTS zone.
All communications with Seattle, Prince Rupert or Victoria Traffic must be made in clear, unbroken English. At least one person capable of conducting two-way radio communications using the English language must be present on the bridge at all times within the Co-operative VTS area. When language problems do arise, communications may be preceded by using message markers as found in the International Maritime Organisation Standard Marine Communication Phrases (SMCP).
