Manitoba / Canada CBP Border — Federal Felony Either Direction

Last verified: May 2026

The Canadian Cannabis Act

Canada legalized recreational cannabis federally on October 17, 2018 via the Cannabis Act. Adults 18+ (or 19+ depending on province) may possess up to 30 g of dried cannabis (or equivalent) in public; provincial frameworks govern retail. Manitoba: cannabis sold through Manitoba Liquor & Lotteries / Manitoba Liquor, Gaming and Cannabis Authority and licensed private retailers; minimum age 19; possession 30 g.

The 310-Mile Border

The North Dakota-Manitoba border runs ~310 miles east-west across the northern tier of ND. The border has 8 U.S. ports of entry:

• Pembina (Pembina County) — ND’s busiest crossing.
• Portal (Burke County) — significant truck traffic on US-52.
• Sherwood.
• Dunseith / International Peace Garden (Rolette County).
• Walhalla.
• Hannah.
• Maida.
• Antler.

Federal Crime Either Direction

Crossing the U.S.-Canada border with cannabis in either direction is a federal crime regardless of Canadian or state legality. The applicable federal framework:

• 21 U.S.C. § 841: federal manufacture, distribution, possession with intent.
• 21 U.S.C. § 844: federal simple possession.
• 21 U.S.C. § 802(16): federal "marihuana" definition.
• U.S. Customs and Border Protection: enforces federal law at ports of entry.

Schedule III rescheduling (April 28, 2026 DOJ order) does not change CBP enforcement of cannabis at the border.

CBP Cannabis Policy Warnings

U.S. Customs and Border Protection has consistently warned that:

• Possession of cannabis at the U.S. port of entry — even by a Canadian citizen with legal Canadian cannabis — can result in seizure, denial of entry, fines, and a lifetime CBP "lookout" record.
• U.S. citizens returning from Canada with cannabis face Schedule I federal drug-trafficking exposure regardless of state legality.
• Working in or investing in the cannabis industry has been used by CBP officers as grounds to deny entry. Canadian cannabis-industry workers and investors have been turned back at the border for industry affiliation alone.

The Pembina Crossing — ND’s Busiest

Pembina is the busiest U.S. port of entry in North Dakota. Located in Pembina County at the I-29 connection, Pembina handles substantial passenger and commercial traffic. CBP officers at Pembina regularly conduct vehicle searches and document cannabis seizures. Given the proximity to Winnipeg (~70 miles north), Pembina sees a high volume of Manitoba residents traveling to the U.S. and U.S. residents returning from Manitoba.

The Portal Crossing — Truck Traffic

Portal (Burke County) handles significant commercial truck traffic on US-52. Cross-border trucking creates specific cannabis-detection challenges; commercial-vehicle inspections at Portal have produced cannabis-trafficking interdictions.

The Dunseith / International Peace Garden Crossing

The Dunseith crossing connects to the International Peace Garden (designated 1932; straddles the U.S.-Canada border at the latitude of the 49th Parallel). The Peace Garden is a tourism destination but the port of entry handles cannabis seizures like any other ND-MB crossing. Notably, Dunseith’s crossing is ~10 miles north of Belcourt and the Turtle Mountain Reservation. See Turtle Mountain page.

Tribal Member Cross-Border Considerations

Turtle Mountain Band of Chippewa Indians members face the same CBP federal-felony exposure crossing the border with cannabis. Title 56 medical authorization within tribal jurisdiction does not extend to federal cross-border movement. Tribal members must approach the border with the same caution as non-tribal travelers.

Common CBP Stop Patterns

• Document checking: routine for all crossings.
• Vehicle inspection: at officer discretion; K-9 deployment available.
• Secondary inspection: for vehicles flagged for additional review.
• Cell phone search: at officer discretion under border-search exception to Fourth Amendment.
• Cannabis questions: officers may ask about cannabis-industry employment, social-media activity, or recent cannabis use.

Working in or Investing in Cannabis Industry

CBP has used cannabis-industry employment or investment as grounds to deny entry to the U.S. Notable cases:

• Canadian cannabis-industry workers turned back at border for employment with licensed Canadian cannabis operators.
• Canadian investors in U.S. cannabis-industry stocks denied entry.
• Lifetime "lookout" records have been imposed for industry affiliation.

Practical Notes

• Never carry cannabis across the U.S.-Canada border in either direction.
• Sealed Canadian product is not safe — CBP enforcement applies regardless of legal Canadian acquisition.
• Industry employment / investment can produce denial of entry independent of physical cannabis possession.
• If you are a U.S. citizen working in the U.S. cannabis industry, consider implications for international travel.
• Federal Schedule III rescheduling does NOT change CBP enforcement.
