Haro Strait is a major shipping channel. Haro Strait, along with Boundary Pass, is the westermost and most heavily used of the three main channels connecting the Strait of Juan de Fuca and the Strait of Georgia. Haro Strait joins Boundary Pass at Turn Point on Stuart Island, where a major navigation beacon, Turn Point Light, is located. Heavy, dangerous rip tides occurs near Turn Point, as well as near the northern end of Boundary Pass, between Patos Island Light on Patos Island and East Point on Saturna Island.
Much shorter than the Rosario Strait, though more difficult to navigate and less sheltered, the strait is the main shipping channel to the Port of Vancouver and other ports around the Gulf of Georgia from the open sea. Navigation through American waters in this stretch by Canadian vessels is sanctioned by the Oregon Treaty, which stipulated that commercial shipping south of the 49th Parallel in these waters would be unmolested.
