List of Canada–United States border crossings explained

This article includes lists of border crossings, ordered from west to east (north to south for Alaska crossings), along the Canada–United States border. Each port of entry (POE) in the tables below links to an article about that crossing.

On the U.S. side, each crossing has a three-letter Port of Entry code. This code is also seen on passport entry stamp or parole stamp. The list of codes is administered by the Department of State. Note that one code may correspond to multiple crossings.[1]

Land ports of entry

Port of entry hours of service for road crossings, except where noted, are open year-round during the day.

The yellow background indicates a border crossing where travel is permitted in only one direction.
The green background indicates a border crossing that is located at a bridge or a tunnel.

Unstaffed road crossings

This is a list of roads that cross the U.S.–Canada border that do not have border inspection services, but where travelers are legally allowed to cross the border in one or both directions.

In prior years, there were dozens of such roads where one could legally cross the border and then proceed to an open Customs office to report for inspection, but most have since been barricaded. Current requirements for reporting to CBSA or CBP for inspection are noted.

Many former uncontrolled roads that served as points of entry along the U.S. Customs and Border Protection Swanton Sector were barricaded/closed in the mid-1970s in securing the 1976 Montreal Summer Olympics.[6] These included Clinton, Franklin and St. Lawrence counties in upstate New York, and in Franklin, Orleans and Essex counties in Vermont.

Chopaka WestChopaka RoadNighthawk WestChopaka RoadCanada periodically provided border services at this crossing on Chopaka Road on the foothills west of the Similkameen River until the US barricaded the road in 1964. The Government of Canada still owns the property at the border. A branch of the Great Northern Railway once crossed the border at this location, but was abandoned in the late 1930s, around the time when the US stopped providing border inspections at the location.[14] 49°N -119.7259°W
Sidley County Route 4777Richard G. Sidley was Territorial Police and Customs Collector 1889–1907. Office replaced by Bridesville.[15] 48.9997°N -119.2578°W
Bridesville Old Molson RoadMolsonOld Railroad RoadBoth were stations on the VV&E, a Great Northern Railway subsidiary. The rail track between Molson and Midway was lifted in 1936. The Bridesville customs office was established in 1907 and closed in 1939. Molson ceased as a port of entry in 1941.[16] The former Customs and Immigration building is included in a museum display at Molson.49.0002°N -119.1794°W
Myncaster Myncaster RoadChesawBolster RoadThe Myncaster customs office, which handled both road and rail traffic, existed 1907–1937. Myncaster was a station on the VV&E, a Great Northern Railway subsidiary. The rail track, which did not cross the border at this location, was lifted between Molson and Midway in 1936. The US ended customs services around 1955. In 1990, the crossing temporarily re-opened to permit the passage of draft horses for competitions in the area, with crossing into Canada permitted on May 14 and crossing into the US permitted on June 9.[17] [18] 49°N -119.0217°W
Newgate Dorr RoadGateway MontanaThis crossing was on the eastern bank of the Kootenay River at the boundary. Customs operations, which began in 1902, inspected both traffic on the river and the adjacent Great Northern Railway branch. The US closed its Customs office when rail service ended in 1935, with officers relocating to the busier Roosville crossing about 5.4miles eastward. The railroad tracks were removed in 1938, and Canada closed its customs office in 1939. The U.S. Post Office closed in 1950 and, what was left of the town was inundated by water in 1975 with the completion of the Libby Dam, which created Lake Koocanusa.[19] 49.0011°N -114.4784°W
Flathead Flathead RdTrailcreek North Fork RdThis crossing was adjacent to the Flathead River. Canada operated a station about a mile north of the border 1904–1905 and closer to the border 1914–1923, 1926, 1931–1941 and from the mid-1940s. In the 1970s, both the US and Canada constructed new border facilities to better accommodate regular recreational traffic. The crossing closed in 1996 due to flooding of the road just north of the border,[20] and the road is now gated. Both the US and Canada station buildings remain.49.0011°N -114.4784°W
Whiskey GapEmigrant Gap RoadAlbertaEmigrant Gap Emigrant Gap RoadThe Canadian port was originally called Fareham. It opened in 1932, but closed in 1939 when the highway through Del Bonita opened. It was once a favorite place to smuggle alcohol from the US into Alberta during its period of prohibition from 1916 to 1923, then from Canada during the US prohibition, which ended in 1933.48.9985°N -113.0963°W
PinhornTownship Road 12Laird Laird RoadCanadian port of entry opened in 1913, and closed in 1929. Customs staff moved the office to Aden, Alberta without authorization, but Canada Customs decided that was a better location anyway.48.9979°N -110.9903°W
Big BeaverSaskatchewanWhitetailThe Big Beaver-Whitetail crossing was established in 1951, where traffic was never extensive. In 2009, the US would plan to use Recovery Act funds to upgrade its Whitetail border station. However, at the same time, Canada would to be planning to close its Big Beaver station. CNN ran a story on how wasteful it would be to spend millions at this crossing. The reporter sat in the middle of the empty roadway during the report.[21] Canada permanently closed their crossing on April 1, 2011, making it a southbound-only crossing. The U.S. POE closed on January 26, 2013.[22] Canada demolished the Big Beaver border station soon after closure. The U.S. border station remains, though the roadway has been barricaded.48.9993°N -105.1623°W
BeaubierSaskatchewan Highway 707SaskatchewanWestbyNorth Westby RoadThe port of Westby, Montana was established in 1919, and was revoked by Executive Order 9382 on September 23, 1943. Shortly before being designated a POE, the town of Westby moved a short distance from North Dakota into Montana to be closer to a new rail spur, and to be in a state that permitted the sale of alcohol.[23] 49°N -104.0782°W
NorthgateSaskatchewanNorthgateNorth DakotaThis border crossing was established in 1913 to serve both highway and rail traffic. The US and Canadian Ports of Entry were abandoned in 1962 when a new highway built about a half mile to the west, bypassing the town. The former US border station was demolished in 2015, and the border community is a virtual ghost town.[24] The building that once served as the Canadian border station remains.48.9988°N -102.2662°W
West Lynne (Emerson West)5th StreetManitobaPembinaThis crossing on the Meridian Highway, whose other end was at the Mexico–United States border in Laredo, Texas, was moderately trafficked through the 1950s, but it was closed in 1964 when Interstate 29 and Manitoba Highway 29 were built immediately to the west. The Canadian and US border stations were demolished, but the concrete slabs on which they stood remain.[25] All road traffic must now use the modern Pembina–Emerson Border Crossing.49.0004°N -97.2351°W
Emerson EastManitobaNoyesMinnesotaThroughout the early 20th century, this was among the busiest U.S.–Canada border crossings. It was the point at which the Jefferson Highway intersected the international boundary and for a few years was adorned with an elaborate archway. Traffic waned with the 1964 opening of Interstate 29 two miles to the west. The crossing was closed by Canada in 2003 (where traffic was permitted southbound only) and then by the U.S. in 2006. All road traffic must now use the Pembina–Emerson Border Crossing.49°N -97.2073°W
Pigeon RiverOld Border Rd (formerly Ontario Highway 61)OntarioPigeon RiverCR 89 (formerly MN 1 (1920) and US 61)Formerly called Sextus City. The Outlaw Bridge as it was known, was built in 1917. It was closed in 1961 when a new bridge and border station were built in Grand Portage, Minnesota about 6 miles to the east. The old bridge, store, hotel and both border stations have all been demolished.48.0104°N -89.7083°W
Niagara FallsRiver RoadNiagara FallsNiagara StreetNew YorkThe Honeymoon Bridge collapsed on January 27, 1938, after an ice jam undermined the structure. A new bridge named the Rainbow Bridge was built a short distance to the north, and new border inspection facilities were built on both sides.43.089°N -79.069°W
QueenstonNiagara Regional Road 81LewistonRobert Moses State ParkwayThe Queenston-Lewiston suspension bridge was replaced by the transverse-named Lewiston–Queenston Bridge in 1962, which was built about 0.7 miles (1.1 km) to the south. The bridge had a single line trolley track of the Niagara Gorge Railroad in the center of 3 lanes. The US inspection plaza has been transformed into the Earl W. Brydges Artpark State Park. 43.1619°N -79.0466°W
CornwallMassenaThe Canadian port of entry on Cornwall Island was closed June 1, 2009, due to a disagreement between the Mohawk Nation of Akwesasne and the Canada Border Services Agency regarding the arming of border services officers. A temporary port of entry was opened July 13, 2009, at the north end of the Seaway International Bridge north (high) span; it was used until the current "interim" port of entry was opened January 24, 2014. The old border station on Cornwall Island was demolished in July 2015.44.9907°N -74.7395°W
Jamieson's LineChemin JamiesonQuébecJamieson LineCounty Road 29The Canadian port of entry was permanently closed on April 1, 2011. For three years, this was a one-way crossing, with travelers able to enter the U.S. but not Canada at this location. Finally, the U.S. port of entry closed August 21, 2014. Both the US and Canada border stations have since been demolished.44.9917°N -74.1747°W
Roxham RoadRang RoxhamRoxham RoadRoxham RoadCanada operated a port of entry at this location until the late 1950s and the building is now a private residence. The US never had a border station at this location. This crossing has been barricaded since the 1970s. Starting in 2017, thousands of migrants made unauthorized entry into Canada on foot at this location so they could request asylum.[26] RCMP established temporary facilities at this crossing to aid in processing the surge in asylum seekers.[27] Canadian regulations regarding asylum procedures were changed in 2023, ending the surge, and the temporary facilities were subsequently demolished after more than 100,000 immigrants requested asylum there.[28] 45.0071°N -73.5172°W
BlackpoolChemin RidgeChamplainThe border crossing on US 9 closed in 1967 when I-87 was completed immediately to the west. The last border station at this crossing was built in 1950 and was demolished soon after it closed in 1967.45.0091°N -73.4419°W
Saint-Bernard-de-Lacolle - 217Meridian RoadMeridian RoadThe port of entry on Meridian Road closed around 1950. The Canada border station was demolished in the mid 1950s. The USDA has since used the old US border station as an office,[29] and the US Government at one time offered it for sale.[30] 45.0091°N -73.4418°W
HighwaterChemin LafondNorth TroySpace Research Corporation RoadVermontIn the 1960s and 1970s, Space Research Corporation founder Gerald Bull built his company on property his family owned on both sides of the border. As the company began building military weapons, the US established a border inspection station outside the company's south gate to inspect southbound traffic. This station also enabled US workers to legally return home after work without having to go through the North Troy border crossing, and it was not for use by the general public. Canada did not have a border station on the company's north gate. The SRC facility (and the Customs station) closed in 1980 when Bull was convicted of violating an arms embargo against South Africa.[31] Bull was assassinated in 1990.45.0085°N -72.4495°W
MansonvilleChemin du Pont-CouvertNorth TroyDouglas RoadAlso known as "Province Hill", Canada Customs closed this office around 1972. The building is now purple and privately owned, but in the 1980s it was rented as a vacation home.[32] Prior to its construction in the 1960s, Canada Customs operated out of a line house across the street. This building was separated, moved about a half mile North and used as cottages.[33] The US did not have a border station at this crossing; persons entering were expected to travel to the North Troy border station for inspection.45.0063°N -72.3747°W
Leadville Chemin des ParulinesNewportLeadville RoadCanada Customs had a station from the mid-1930s to 1939, then reopened in 1948. It was replaced with a new border station in the mid-1950s, which permanently closed on March 31, 1969.[34] The Canada border station was converted into a private home that has been updated substantially. There was no US border station at this location; persons entering the US here were expected to travel to the US Customs office at 70 Main Street, Newport, VT to report for inspection. That office closed in 1972, and the road was barricaded. Today the former US Customs office is home to Northeast Kingdom Community Action.45.0042°N -72.2746°W
Leadville Chemin de LeadvilleNewportLake RoadAlthough this was a busy road with many lakeside homes, neither the US nor Canada had a border station here. Persons entering the US here were expected to travel to the US Customs office at 70 Main Street, Newport, VT to report for inspection. That office closed in 1972, and the road was barricaded at the border at that time.45.0044°N -72.2585°W

Grand FallsCaswell RoadNew BrunswickCaswell(unnamed road)The US operated a border inspection station between 1936 and 1953. The General Services Administration purchased approximately a half acre of land in 1931, and constructed a red brick border station. The property was sold by the US government on October 13, 1954,[36] and although the included the brick building, it has since been demolished. The parcel, and the road leading to the border from Route 1A are now private property. It is not known whether Canada had a border station on Caswell Road.47.0416°N -67.7901°W
Four FallsBrown RoadEast Road Russell RoadCanada still provides Customs services seasonally, but US-bound traffic is prohibited, and has been since the US border station closed in the 1960s. However until 2008, US-bound traffic was permitted to use the road to the Aroostook Valley Country Club, which is in both countries. Several Canadian properties can only be accessed via the US part of the road, which pre-dates the establishment of the border; several residents have experienced harassment from U.S. Border Patrol officers since 9/11.[37] [38] 46.8234°N -67.7896°W
TinkerTinker RoadFort FairfieldAroostook Falls RoadThe US operated a border station at this crossing from 1941 to 1953. It was located about 500 feet west of the Canada–US border, with a private home standing between it and the border. The General Services Administration purchased the property for the border station on May 20, 1940, and placed a portable building on the property. GSA removed the building and sold the property on October 21, 1955.[39] In 1970, the Canadian Magazine declared this crossing "The best place to sneak across the border,"[40] The road was barricaded around 1976. The Aroostook River flood of 1994 killed 2 Canadian Customs officers whose vehicle was swept into a ditch by rising flood waters at this crossing.[41] 46.7934°N -67.7896°W

WoodstockOld Houlton RoadHoultonPrior to the 1950s, the Canadian road to this crossing traversed a steep hill at the border, which caused problems for winter travelers. Around 1952, Canada excavated much of the hill and built a new inspection plaza on relatively level ground. This border crossing was closed in 1985 when I-95 was completed immediately to the north.[45] The Canada border station, which was sometimes called Richmond Road, was demolished. The US border station and adjacent staff residences remain in disrepair.46.1333°N -67.7812°W
