At Sweetgrass–Coutts, the line often bogs down before travellers reach the booth. The usual problem is plain: someone arrives without the right document in hand, or with receipts buried somewhere in the vehicle. CBSA told travellers on March 31, 2026 to plan ahead for the Easter long weekend, and the advice fits this crossing well. Holiday traffic rises fast, and extra time disappears even faster.
That sounds basic. It is not.
For northbound travel from Montana, the first question is not where you are going. It is which document matches the way you are crossing. Keep it ready before primary inspection. A clean handoff can save a long secondary wait.
Start with identity. Most U.S. citizens entering Canada by land need a valid U.S. passport. IRCC also lists other documents that can work in some cases: a birth certificate, certificate of citizenship or naturalization, certificate of Indian status with photo ID, or a U.S. enhanced driver’s licence. U.S. lawful permanent residents follow a different rule depending on the mode of travel.
By land, a U.S. permanent resident normally needs a valid green card or equivalent proof of status. By air, the file is larger: passport from the country of nationality, plus the green card or equivalent proof of status. People mix up those rules when they prepare for one trip and take another. The border does not care how you packed.
Quick note: Dual Canadian-U.S. citizens can enter Canada with a valid Canadian or U.S. passport. A valid U.S. passport is enough for that trip; a Canadian passport, visa, or eTA is not required in that case.
the part most travelers get wrong
The problem is not only nationality. Route matters too. IRCC says U.S. permanent residents entering by land or water directly from the United States need proof of permanent resident status, such as a valid green card, certain temporary I-551 or ADIT documents, some expired green cards paired with the right Form I-797 notices, a valid re-entry permit, or an I-94 with an unexpired ADIT stamp and passport-style photo. A passport alone does not cover that case.
If your entry requires a visa, it has to be in hand before you arrive. Some travellers need an eTA instead, depending on nationality and status. Sweetgrass–Coutts is a poor place to sort that out at the booth. An incomplete file slows the conversation, and the queue absorbs the delay.
In practice, this matters far more than the official language suggests. Officers are checking admissibility, document match, and anything that must be declared in the vehicle. Keep passport, PR card or status proof, and any required visa or eTA in one place, separate from luggage and groceries. No glove-box scavenger hunt.

why the wait gets worse at holidays
CBSA’s March 31 notice was not written for Sweetgrass–Coutts alone, but the advice applies here. Holiday periods bring more traffic, and Monday on long weekends tends to be the busiest stretch. Early mornings are usually the safest window. Go before the rush.
That is the easiest part to control.
Have receipts ready for anything you are bringing back. CBSA tells residents to know the value of goods in Canadian dollars and keep receipts available. The same applies to alcohol, tobacco, and other items you plan to declare. If something is unclear, declare it. Guessing wrong costs more.
CBSA also reminds travellers to be open about items they are not sure about. If children are travelling with you and you do not have legal custody, bring a consent letter. Pets need the paperwork that applies to the animal. People moving household goods should file BSF186 before they get to the border. We covered the Crossing with Children: Why a Consent Letter Matters for Single-Parent Travel and the Moving your belongings to Canada: how to file the BSF186 at the border processes separately because both show up often at land crossings.
Sweetgrass–Coutts rewards people who pack for the border, not for the trip. One document in the wrong pocket can cost more time than the drive north.
