- LNM13-C58F2APAN PANBOUNDARY PASS General / Threatened And Endangered Species Advisory (TESS Advisory) / Marine Wildlife Migration Effective 01 Jun (exact date TBC by ECHO team based on SRKW presence) to 30 Nov 2026, the Enhancing Cetacean Habitat and Observation (ECHO) Program voluntary ship slowdown through Haro Strait and Boundary Pass is in effect for all inbound and outbound commercial and government vessels to reduce underwater noise for at-risk whales. If it is safe and operationally feasible to do so, commercial and government vessels are requested to not exceed the following speeds through the water: 11 knots – Bulkers, tankers, general cargo vessels, and government vessels; and, 14.5 knots – Vehicle carriers, cruise ships, and container vessels. This voluntary slowdown takes place between 48°24'22.78"N, 123°12'15.26"W, and 48°46'39.28"N 123°1'36.84"W. Speed transition zones are in place within the established traffic system at both approaches to the slowdown area. The north transition zone are those waters between north of Boat Pass, Saturna Island and Rosenfeld Rock and the south transition zone are those waters between buoy VH at the Victoria pilot station, and Sea Bird Point at the southeast corner of Discovery Island. There are also two optional slow down areas, one rounding turn point and the other between Turn point, Saturna Island and Alden Point, Patos Island. This initiative will remain in effect 24 hours per day until 23:59 PDT on 30 Nov 2026, depending on southern resident killer whale presence in the fall. The ECHO Program is led by the Vancouver Fraser Port Authority in collaboration with government agencies, Indigenous communities, industry partners and environmental groups.
