Border crossing RV — US / Canada / Mexico in 2026

Required documentation entering Canada (US citizens + LPRs): valid passport or NEXUS card or Enhanced Driver's License. Vehicle registration. Rental authorization letter (if rented vehicle) from rental company including rental company permission to cross border.

Returning to US: same documentation plus ArriveCAN no longer required (sunset 2022). Random inspection rate ~10% at major crossings.

• Passport / NEXUS / EDL required
• Vehicle registration + insurance
• Rental authorization letter (for rented vehicle, MUST include border-cross permission)
• Firearms: declare at border, separate permit (Form CAFC 909) required
• Cannabis: prohibited from crossing, even with US state legalization

Pets: dogs + cats need current rabies certificate (within 3 years for dogs, within 1 year for cats). Verify per CBSA pet policy.

Plants: fresh fruits + vegetables + plants typically prohibited from crossing. Frozen + cooked food generally allowed.

Food: meat + dairy products restricted; declare all food at border. Random food inspections common.

Required for entering Mexico (US citizens): FMM (Forma Migratoria Multiple) tourist card ($30-50 USD, available at border or online), Temporary Vehicle Import Permit (TIP, $50 USD, valid 6 months — REQUIRED for any vehicle entering beyond border-zone), proof of Mexican auto insurance (US insurance NOT valid in Mexico).

TIP is critical: bring vehicle registration in driver's name OR notarized authorization from owner (rental company). RENTALS RARELY PERMIT MEXICO TIP. Verify rental contract before assuming.

• FMM Tourist Card: $30-50 USD
• Temporary Vehicle Import Permit (TIP): $50 USD, 6-month max
• Mexican auto insurance: required (US not valid), $5-25/day
• Most US RV rentals PROHIBIT Mexico crossings — verify contract

Propane: legal to cross with full or partial tank in all 3 countries, but verify tank seal + valve closure. Inspect for leaks; border agents may decline crossing if leak detected.

Fuel: alcohol-blended gasoline (E10, E15) is standard in US; Mexico fuel quality varies. Plan to enter Mexico with full tank.

Alcohol: $200 USD per adult duty-free limit entering Canada (1.5L wine or 1.14L spirits or 24 cans/bottles beer). $400 USD per adult for stays > 48 hr.

Canada: Non-restricted firearms (most rifles + shotguns) permitted with declaration + Form CAFC 909 ($25). Restricted (handguns) generally PROHIBITED except for specific competition shooters with prior authorization.

Mexico: ALL firearms PROHIBITED for tourists. Strict enforcement. Possession = federal arrest. Search rig thoroughly before crossing; cartridges + casings count as firearms-related contraband.

Wait times vary by crossing + time of day. Apps: CBP One (US-Mexico + US-Canada wait times, official), MyBorderPass (commercial alternative), BWT (Border Wait Times unofficial real-time updates).

Optimal crossing times: early morning weekdays (5-7 AM) have lowest wait times. Weekend afternoons + holidays have highest waits (often 2-4 hours).

The under-shared truth: rental companies that DO permit Canada crossings often require: (1) advance written authorization (request 4-6 weeks ahead), (2) Canadian-coverage insurance rider ($50-150/trip), (3) verified return date with no extensions allowed in Canada.

Second under-shared truth: most Class A coaches + larger rigs are physically too large for some US/Mexico border crossing infrastructure (low canopies, narrow lanes). Verify rig dimensions vs crossing-specific clearances before route planning.
