Travel commonly occurred near or along the shores of
Boundary Bay between the respective international boundaries. To address the customs implications of such journeys, a customs office was established at Boundary Bay in 1914. E.T. Calvert conducted the initial customs role from his home about north of the boundary. His duties comprised patrolling the area by boat or on horseback. In 1935, customs offices were built at the boundary on the main road and eastward at Beach Road (67 Street). Having operated under the administrative oversight of the Port of New Westminster, the status was upgraded in 1948 to the Port of Boundary Bay. In 1975, the Beach Road post closed permanently. The latest owner of this heritage building renovated the interior to accommodate a dental office. In 1977, the main crossing approach was widened from one to two lanes. Commercial goods are transported by vehicle under custom's seals between the US mainland and Point Roberts. The
CBSA office is open 24 hours. ==US side==
