In 1895,
Cascade City was surveyed to form a townsite as a base for
prospecting and a stop on the anticipated westward extension of the
Columbia and Western Railway (C&W). By 1897, the mining boom was drawing numerous prospectors from south of the border. To address the consequences, a customs office opened that year in the town. In August 1899, the rail head of the C&W, a
Canadian Pacific Railway subsidiary, reached the town. The same year, the customs office came under the administrative oversight of the Port of Grand Forks. Under the Washington and Great Northern Railway (W&GN) charter, the
Great Northern Railway (GN) laid track northward from
Marcus (WA), reaching the border in March 1902. On completion of the ongoing track, Canada Customs applied seals to those freight cars entering at
Carson and Cascade, which were purely transiting between these two points. In 1932, new customs facilities were erected. In 1948, the government bought the site from the Cascade Development Company. That year, the status was upgraded to the Port of Cascade City and oversight of the Carson crossing was transferred from Nelson. For decades, Washington residents have used the crossing to reach their summer cottages at Christina Lake. Canada replaced the building in 2007. In 2020, a stolen vehicle rammed through the closed crossing barriers in the early hours. The driver was later detected fleeing on foot. His attempt to evade capture by jumping into the
Kettle River ended after a two and a half hour float chase. The
CBSA office is open 8am to 8pm. ==US side==
