Every year, tens of thousands of Canadians drive south for winter sun or catch flights to American cities. If you’re among them, 2025 brings more paperwork than most people realize — and some changes that could catch even seasoned travelers off guard. From a new fee that sounds steeper than it is, to expanded biometric checks and fresh reporting rules for long-stay visitors, here’s what you actually need to know before you cross.

What are the new rules for Canadians crossing the U.S. border?

Three major policy shifts landed in 2025, each affecting a different group of Canadian travelers. Whether you’re crossing by car or plane, staying three days or three months, the rules now demand more attention than they did a year ago.

By car

Driving from Canada into the United States means presenting documents to Customs and Border Protection at a land port of entry. Canadian citizens aged 16 and older need a passport, a Trusted Traveler Program card like NEXUS, an enhanced driver’s license, or a Secure Certificate of Indian Status — all of which must be machine-readable according to the Government of Canada travel advisory.

One wrinkle that catches many land crossers: unlike air travelers, you won’t automatically receive an I-94 arrival/departure record at a land port. If you plan to stay 30 days or longer and no I-94 is issued to you, you must register online using USCIS Form G-325R guidance, a free filing available through USCIS. Requesting a manual I-94 at the border instead triggers a $30 fee, plus fingerprints, a photo, and possible secondary inspection, according to Canada to USA.

Document note

Children under 16 can cross with a birth certificate alone under the Western Hemisphere Travel Initiative, but the Government of Canada recommends a passport regardless — it’s the only document that removes all ambiguity with CBP officers.

By air

Flying into the United States from Canada is straightforward on the document front: a valid passport or NEXUS card is all that’s needed at the checkpoint. The US CBP Help portal confirms that Canadian citizens by air require either document. Unlike land entries, an I-94 is automatically generated for air travelers.

What changes in 2025 is what happens after you land and stay longer than 30 days. According to Air Canada travel advisories, Canadian passport holders may be asked to present or confirm their I-94 for stays extending beyond 30 days.

General updates

Two cross-cutting changes apply whether you arrive by land, air, or sea. First, alien registration for stays of 30 days or longer became enforceable April 11, 2025, per the VisaServe comprehensive guide. Canadians aged 14 and older without prior biometric registration on file must submit to fingerprints upon entry and notify DHS of any address change within 10 days. Second, the CBP final rule on biometric entry-exit was published October 27, 2025, with full implementation beginning December 26, 2025 — at which point photos and fingerprints will be collected from all non-US citizens at every port, according to the Canadian Snowbird Association biometrics rule announcement.

Bottom line: The implication: border crossings will take measurably longer from late December onward, and anyone who hasn’t crossed recently should build in extra time.

What do you need to cross the Canadian border into the US?

The answer depends on your citizenship status and your mode of transport — but the core document set hasn’t changed for Canadian citizens.

Documents for citizens

  • Passport or NEXUS card (air travel)
  • Passport, NEXUS, Trusted Traveler card, enhanced driver’s license, or SCIS (land/water travel, age 16+)
  • Machine-readable Secure Certificate of Indian Status recommended alongside passport

The pattern across transport modes is straightforward: you need one REAL ID-compliant document that proves both identity and Canadian citizenship. A standard driver’s license won’t cut it at the land border for adults — it lacks the citizenship confirmation CBP requires. NEXUS remains the fastest lane at both air and land ports, and the fee for enrollment ($50 for five years) is a worthwhile investment for regular crossers.

Permanent residents

Canadian permanent residents face a different situation. As foreign nationals, they generally need a non-immigrant visa — typically a B-1/B-2 visitor visa — to enter the United States, regardless of how long they plan to stay. The Snowbird Advisor fee analysis notes that this is where the new $250 Visa Integrity Fee becomes relevant: unlike Canadian citizens, permanent residents who require a visa will need to pay it.

One unresolved question reported by Snowbird Advisor: whether Canadian PRs from Visa Waiver Program countries might qualify for the 90-day tourist exemption from the fee. That interpretation hasn’t been confirmed by official DHS guidance as of this writing.

Bottom line: Canadian citizens face no new entry fee — the $250 Visa Integrity Fee targets visa applicants. Most snowbirds who cross as tourists don’t need to budget for it. Permanent residents from visa-required countries should expect the fee and plan accordingly.

Do I have to pay $250 to enter the USA?

Short answer for the vast majority of Canadian visitors: no. The Canadian Snowbird Association fee clarification explicitly states the fee does not apply to Canadian citizens visiting temporarily as tourists.

Fee details

The $250 Visa Integrity Fee was established by the One Big Beautiful Bill Act, which appears to have been passed in mid-2025, and takes effect October 1, 2025, per FH&P Lawyers fee implementation analysis. It applies to applicants for certain non-immigrant visas — primarily B-1/B-2 visitor visas and H-1B work visas. Since Canadian citizens don’t need a visa or ESTA for tourist visits of up to six months, they’re not subject to this fee.

Who pays

  • Canadian citizens visiting as tourists: exempt
  • Canadian permanent residents requiring a visitor visa: subject to fee
  • Visa applicants from countries outside the Visa Waiver Program: subject to fee

The fee is tied to the visa application itself, not to the border crossing. If you never need a visa, you never pay the fee. The Snowbird Advisor confirms that most Canadian snowbirds — who travel on Canadian passports — fall into the exempt category.

One caveat: while the fee is reimbursable if visa conditions are met, the reimbursement process hasn’t been fully detailed by USCIS, according to Snowbird Advisor. Travelers who do pay it should keep documentation in case a future claim becomes viable.

What are the new border rules for Canadian snowbirds?

“Snowbird” describes Canadians who spend part of the year in the United States, typically during winter months. The 2025 changes hit this group harder than short-stay tourists.

Reporting changes

The alien registration requirement that took effect April 11, 2025, is the most immediate concern for snowbirds planning stays of 30 days or longer. According to VisaServe, the rule covers Canadians aged 14 and older who don’t already have biometric data on file with US authorities. Upon entry, this means fingerprints — on top of the biometrics that will roll out universally from December 26.

If you cross by land and no I-94 is issued to you at the crossing, you must file Form G-325R online — a free procedure that registers your presence with USCIS. The Canada to USA guide notes that requesting a manual I-94 at the land border instead costs $30 and subjects you to CBP’s full secondary inspection process. The cheaper, faster path is to cross, then file online.

Extended stays

Snowbirds should carry three things at all times: a passport, proof of Canadian residence, and travel insurance documentation, according to the Canadian Snowbird Association. Insurance proof matters more than ever — with heightened scrutiny under the current US administration, as noted by Barclay Damon legal analysis, officers may ask about your ability to cover medical costs during an extended stay.

What to watch

The 30-day threshold trips up many snowbirds who don’t realize they need to register. If you cross in October and plan to stay through March, you cross that threshold in November. Set a calendar reminder to file Form G-325R within 10 days of crossing if no I-94 was issued at the port. Missing this step exposes you to enforcement action that most crossers in prior years never faced.

Can Canadians be denied entry to the US?

Yes — and the bar for denial isn’t as high as many Canadians assume. Being a Canadian citizen doesn’t guarantee entry; it only removes the visa requirement.

Common reasons

  • Inability to demonstrate ties to Canada (job, property, family) that confirm intent to leave
  • Lack of travel health insurance for extended stays
  • Prior immigration violations in any country
  • Misleading answers to CBP questioning about purpose or duration of stay
  • Under the current administration, heightened scrutiny applies broadly, per Barclay Damon legal analysis

Air Canada has warned that certain foreign nationals holding visas face restricted entry rules effective after December 31, 2025 — though this applies to visa holders, not visa-exempt citizens.

What to know

The practical risk for Canadian citizens is lower than for most other nationalities, but it’s not zero. Preparation is the antidote: carry evidence of your Canadian residency, have a clear answer for how long you plan to stay, and never volunteer information CBP officers don’t ask for.

The catch: even well-prepared travelers can face secondary inspection, which delays crossing and gives officers time to dig deeper. Land ports have historically been less consistent in issuing I-94 records than air ports, which is why the Canada to USA guide recommends checking your I-94 status online after every land crossing.

Step-by-step: crossing the U.S. border from Canada

  1. Verify your documents. Citizens traveling by air need a valid passport or NEXUS card. By land or water, you need a passport, NEXUS, Trusted Traveler card, enhanced driver’s license, or SCIS — and you must be 16 or older.
  2. Determine your length of stay. Stays under 30 days with no I-94 issued require no registration action on your part. Stays of 30 days or longer without an I-94 require online registration via Form G-325R within 10 days of entry.
  3. Cross and watch for I-94. If entering by air, an I-94 is automatically generated — note the number and confirmation. If crossing by land, confirm with the CBP officer whether one has been issued to you. If not, file Form G-325R online promptly.
  4. Prepare for biometrics. Starting December 26, 2025, expect a photo and fingerprint scan at every crossing. Build additional time into your travel plans, particularly at land ports where processing infrastructure varies.
  5. Keep records accessible. Carry your passport, proof of Canadian residence, travel insurance documentation, and any I-94 confirmation. If your address changes during a stay of 30+ days, report it to DHS within 10 days.
Bottom line: For Canadian snowbirds who plan ahead, the 2025 changes are manageable. File Form G-325R when required, check your I-94 status online after land crossings, and carry proof of residency and insurance. Travelers who skip the registration step expose themselves to enforcement risk that most crossers in prior years never faced.

Timeline of 2025 U.S. border changes affecting Canadians

The following timeline tracks the major regulatory milestones that Canadian travelers need to track in 2025.

Date Change
April 11, 2025 Alien registration for stays of 30+ days becomes enforceable
July 4, 2025 One Big Beautiful Bill Act passed, introducing $250 Visa Integrity Fee
October 1, 2025 $250 Visa Integrity Fee takes effect for visa applicants
October 27, 2025 CBP final biometric rule published
December 26, 2025 Biometric collection begins at all ports for non-US citizens
December 31, 2025 Visa ineligibility for certain foreign nationals takes effect

The pattern across these dates shows a deliberate acceleration of enforcement mechanisms: registration requirements preceded the fee implementation, and biometric collection followed the rule’s formal publication. Travelers should expect the cumulative effect of these measures to reshape the crossing experience by year-end.

Confirmed facts vs. unclear areas

Confirmed facts

  • Canadian citizens need passport or NEXUS for air travel
  • Visa Integrity Fee exempts Canadian citizens visiting as tourists
  • I-94 auto-generated for air entries; manual or G-325R for land without I-94
  • Alien registration rules begin April 11, 2025
  • Biometric collection starts December 26, 2025
  • Permanent residents requiring visas are subject to the $250 fee
  • Address changes must be reported to DHS within 10 days for registrants

What’s still unclear

  • Whether Canadian PRs from Visa Waiver countries qualify for fee exemption
  • How uniformly land ports will enforce the G-325R registration requirement
  • Whether the fee reimbursement process will be formalized by USCIS
  • Regional variations in port processing times post-December 26

Canadian Snowbird Association

“This fee does not apply to Canadian citizens who are visiting the United States temporarily as tourists, including those spending the winter in the U.S. as snowbirds.”

Canadian Snowbird Association

“Plan for extra time at border crossings once the rule takes effect on December 26, 2025.”

The Snowbird Advisor adds context for the fee confusion: most Canadian snowbirds traveling on Canadian passports won’t need to pay the new $250 charge because no visa is involved. The fee was designed for visa applicants — not for citizens of visa-exempt countries.

The trade-off

For snowbirds, the $250 fee that sounds alarming is largely irrelevant — but the alien registration rules that most people haven’t heard about are the ones that could create real problems. A traveler who forgets to file Form G-325R after a six-month winter stay faces far greater practical risk than one who never encounters the Visa Integrity Fee.

Frequently asked questions

What documents do you need to enter the U.S. from Canada by car?

Canadian citizens aged 16 and older need a passport, NEXUS card, Trusted Traveler card, enhanced driver’s license, or Secure Certificate of Indian Status. A standard driver’s license is not sufficient for land crossings under the Western Hemisphere Travel Initiative.

Will Canadians have to pay $250 to enter the US?

Most Canadian citizens will not. The $250 Visa Integrity Fee applies to applicants for non-immigrant visas. Canadian citizens visiting as tourists for up to six months don’t need a visa, so they’re exempt from the fee. Permanent residents who require a visitor visa are subject to it.

What is the lonely Canadian rule?

This appears to be a colloquial reference to situations where a Canadian crosses the border alone or without clear ties to Canada, potentially triggering greater scrutiny from CBP officers. The official rules don’t use this term, but officers have discretion to question travelers whose circumstances raise concerns about their intent to return.

What do you need to cross the Canadian border by car?

A passport, NEXUS, Trusted Traveler card, enhanced driver’s license, or SCIS for travelers 16 and older. Children under 16 can cross with a birth certificate, though a passport is strongly recommended to avoid delays or denials.

What are requirements for entering U.S. from Canada by air?

A valid passport or NEXUS card is required for Canadian citizens flying to the United States. No visa is needed for tourist visits of up to six months. An I-94 is automatically generated upon arrival, and starting December 26, 2025, biometrics (photo and fingerprints) will be collected.

Can Canadian permanent residents enter the U.S. without a visa?

Generally no. Canadian permanent residents are foreign nationals and typically need a non-immigrant visitor visa (B-1/B-2) to enter the United States, regardless of how long they plan to stay. This means they are also subject to the $250 Visa Integrity Fee when applying for that visa.

What causes denial of entry for Canadians to the US?

Common reasons include failing to demonstrate sufficient ties to Canada, lack of travel health insurance for extended stays, prior immigration violations, or inconsistent answers to CBP questioning. Even Canadian citizens can be denied entry if an officer determines the visitor doesn’t intend to leave or poses a security concern.
