What to know about crossing the US Canada border during and after COVID
Crossing the land border between the United States and Canada continues to be affected by COVID-19 policies, even as many emergency measures have ended. This evergreen explainer summarizes the current, evidence-based requirements, documentation you will need, testing and vaccine expectations, and how procedures have changed over time. It is designed to help travelers understand what to expect when entering by land or water, not by air, focusing on durable rules and clarifying what is still recommended versus what is no longer mandatory.
Entry requirements and proof of vaccination
Both sides of the border maintain distinct entry rules for travelers, and proof of vaccination is a central topic for many cross-border trips. Below is a concise overview of key attributes related to proof of vaccination and identity at the border.
| Attribute | Verified Detail | Source Type |
|---|---|---|
| Vaccine proof for air travel | Required for inbound passengers to Canada and for entry to the United States by air. | Government of Canada; U.S. CDC/DHS |
| Vaccine proof for land entry | Not currently required for general cross-border land travel as of late 2024, but policies may change. | Government of Canada; U.S. Customs and Border Protection |
| Accepted vaccines | Health Canada and U.S. authorized or approved products (mRNA and protein-based vaccines widely accepted). | Health Canada; U.S. FDA |
| Digital vs. paper | Digital records accepted in many cases, but paper copies remain useful at land ports of entry. | ArriveCAN app guidance; CBP guidance |
Because rules can shift quickly with new variants or policy announcements, always recheck requirements within 72 hours of travel, and confirm the specific requirements of your port of entry. Requirements for air travel are generally stricter than for land or water entry, so verify the mode of transport separately.
Traveler checklist for land entry
- Valid passport or enhanced driver’s license (if eligible) from the country you are entering.
- Proof of vaccination if you are entering by air or if you are moving across long-term stays.
- Digital or paper copy of vaccination records, with translations if necessary.
- Completed declaration forms if required (for example, via ArriveCAN or CBP forms).
- Plan for possible inspection and questioning, including declaring goods and food items.
Testing, quarantine, and symptom management
Testing and quarantine policies at land borders are generally less stringent than they were during peak pandemic periods, but expectations around symptom awareness and responsible behavior remain. Travelers should understand how these measures apply in practice.
- Pre-departure testing: Not routinely required for fully vaccinated travelers entering by land, but may be requested during outbreaks or for specific high-risk settings.
- On-arrival testing: Generally not mandatory at land ports, except in targeted scenarios or if directed by public health officials at the port.
- Quarantine rules: Official quarantine mandates are rare at land crossings now, but voluntary isolation is recommended if you have symptoms or a positive test.
- Mask use: Recommended in crowded indoor border facilities and on public transport, and may be required during local public health advisories.
Because policy can vary with regional case levels and variant concerns, check the latest guidance from the Public Health Agency of Canada and U.S. state or local health authorities if you are crossing during periods of high community transmission.
Documentation for different traveler groups
Different traveler categories face distinct rules, and documentation needs vary significantly between citizens, permanent residents, visitors, and essential workers. Below is a breakdown that highlights who needs what when crossing by land.
| Traveler group | Entry document | Notes |
|---|---|---|
| Canadian citizens | Canadian passport or citizenship certificate; U.S. passport or NEXUS/FAST trusted traveler card if entering by land. | Proof of citizenship and identity sufficient. |
| U.S. citizens | U.S. passport, passport card, or other WHTI-compliant document. | Land border rules allow some alternate documents that are not valid for air travel. |
| Permanent residents | Permanent resident card of the country being entered, plus passport of origin if required. | May face additional secondary inspection and must meet admissibility rules. |
| Visitors/tourists | Valid passport and, depending on length of stay, visa or eTA (Canada) or appropriate U.S. authorization. | Proof of ties, funds, and return plan may be requested at the port. |
| Essential and cross-border workers | Work documentation, possible additional Trusted Traveler program enrollment (NEXUS, FAST, SENTRI). | May use dedicated lanes and simplified entry when programs and eligibility apply. |
Special programs like NEXUS, SENTRI, and FAST can expedite land crossings and reduce direct inspection. Enrollment is not linked to vaccine status but may require in-person interviews at enrollment centers. If you are a frequent cross-border traveler, these programs are worth evaluating for time savings and clearer lane access.
Border operations and process during the post-COVID period
At land ports of entry, processes have largely returned to pre-pandemic patterns, though some digital tools introduced during COVID-19 remain in place. Expect standard procedures such as document checks, questioning about your visit, possible secondary inspection, and declaration of goods. Wait times vary by location, time of day, and whether you are enrolled in a trusted traveler program, and you can check current border wait times through official government tools. In general, courteous cooperation, honesty about your plans, and having your documents ready will make crossings smoother.
What to expect at a land port of entry
- Vehicle and pedestrian lanes are clearly marked; follow signage and instructions from officers.
- Primary inspection involves document checks and initial questioning.
- If selected for secondary inspection, you may be asked additional questions and your vehicle or belongings may be inspected.
- Declaration of restricted or prohibited items (food, plants, animals, currency over certain thresholds) is required.
- Wait times can be checked online before you travel; factor extra time during peak periods.
Changes over time and how to stay updated
Since the beginning of the pandemic, border rules have shifted multiple times in response to case trends, variant concerns, and evolving scientific evidence. Key shifts relevant to land entry include the introduction and relaxation of vaccine proof requirements, changes to testing mandates, adjustments to quarantine guidance, and the continued rollout of trusted traveler programs. For the most dependable, up-to-date information, rely on primary sources such as government agencies rather than informal reports or outdated summaries.
To stay current, check the official resources listed below shortly before you travel. If you are unsure about admissibility due to health, criminal, or other grounds, contact a border services officer in advance or seek advice from a qualified professional who specializes in cross-border compliance.
