🛳 Crossing the US–Canada Border by Sailboat

Crossing between the United States and Canada by sailboat is one of the finest cruising experiences in North America — the Gulf Islands, Desolation Sound, the Inside Passage, the Great Lakes, and the Bay of Fundy are extraordinary destinations. But the border is a real border, and both countries enforce it seriously. This guide covers everything a sailor needs to know: documents, procedures, prohibited items, apps to use, and the specific differences between crossing in the Pacific Northwest and crossing on the Great Lakes.

This is general guidance only — not legal advice. Border regulations change. Always verify current requirements with CBSA (Canada) and CBP (US) before every crossing. Violations can result in seizure of your vessel, fines, and denial of future entry.

Reporting to CBSA — Canada Border Services Agency

US to Canada: The Rules

When you depart US waters bound for Canada, you are entering Canadian jurisdiction the moment you cross the border. You must report to Canada Border Services Agency (CBSA) immediately upon arrival at a designated port of entry — before anyone leaves the vessel or any goods are offloaded. No exceptions.

Step-by-Step Entry Procedure

  1. Notify CBSA before or upon arrival. Use the CBSA ROAM App (strongly recommended) to submit your advance arrival notice and customs declaration from your phone before you reach the dock. Alternatively call the CBSA Telephone Reporting Centre: 1-888-226-7277 (available 24/7).
  2. Proceed directly to a designated CBSA reporting marina or dock. Do not stop anywhere else. Do not anchor in Canadian waters and go ashore. Go straight to your reporting location.
  3. Secure the boat. Hoist the yellow quarantine flag (Q flag) until you have been cleared by CBSA. This signals you are awaiting customs inspection.
  4. Only the captain/skipper goes ashore to report to CBSA. All other crew and passengers remain aboard until CBSA has cleared the vessel. No exceptions.
  5. Declare everything. Alcohol, food, tobacco, pets, firearms, cash over CAD $10,000, gifts. When in doubt, declare it. Failure to declare is far worse than declaring and paying duty.
  6. CBSA grants entry. Once cleared, lower the Q flag. All crew and passengers may now leave the vessel. You may proceed to your cruising destination.
  7. Record your CBSA transaction number. You may be asked for it at subsequent Canadian stops or upon re-entry to the US.

The CBSA ROAM App

Download CBSA ROAM before you leave the dock. Available free on iOS and Android. The ROAM app (Report On Arrival Mobile) allows you to submit your customs declaration and notify CBSA of your arrival in advance — speeding up the process significantly. You can complete declarations for your entire crew. Many CBSA reporting locations now handle the majority of pleasure craft crossings entirely through the app with no in-person officer required.

Designated CBSA Reporting Ports for Pleasure Vessels

You must report to a CBSA-designated marina or dock — not just any slip. Calling from an undesignated location is not acceptable. Confirm the current list with CBSA before your crossing as it changes.

Bedwell Harbour (South Pender Is.)BC — Primary US/Canada crossing port; fuel, marina, direct US access
Sidney, BC (Port Sidney Marina)BC — Full services; near Victoria; convenient for Gulf Islands bound boats
Victoria, BCBC — Multiple reporting options; Inner Harbour; Westbay Marine Village
Nanaimo, BCBC — Central Vancouver Island; full services
Ganges (Saltspring Island), BCBC — Gulf Islands reporting location; limited hours — call ahead
Fort Erie, ONGreat Lakes — Niagara River; across from Buffalo NY
Windsor, ONGreat Lakes — Detroit River; full services
Kingston, ONGreat Lakes — Lake Ontario; Confederation Basin; 1976 Olympic venue
CBSA designated location hours vary. Some remote locations are telephone-only; some are seasonal; some have limited hours. Always confirm with CBSA at 1-888-226-7277 before crossing to verify that your intended reporting location is current and what its hours are. Arriving at a closed reporting dock with no backup plan is a serious problem.

Reporting to CBP — US Customs and Border Protection

Canada to US: The Rules

Returning to the United States from Canada requires reporting to US Customs and Border Protection (CBP) immediately upon crossing into US waters. The rules are stricter and the consequences of non-compliance are more severe than most sailors expect — CBP takes unauthorized entry very seriously. All crew members, all goods aboard, and the vessel itself are subject to inspection.

Step-by-Step Return Procedure

  1. Use the CBP One App OR call CBP before or immediately upon entering US waters. CBP One (free, iOS and Android) is the preferred method. You can submit your arrival notice and all crew/passenger information in advance. Alternative: SVRS (Small Vessel Reporting System) — 1-800-562-5943 for Pacific Northwest; numbers vary by CBP sector — confirm your sector’s number before crossing.
  2. Proceed directly to a designated CBP reporting dock. Same rule as Canada — go straight to a port of entry. Do not stop elsewhere.
  3. All crew and passengers remain aboard until CBP clears the vessel (unless directed otherwise by a CBP officer). Captain handles all communications initially.
  4. Declare all goods. Duty-free limits apply (see below). Declare everything purchased in Canada: food, alcohol, tobacco, gifts, souvenirs. US duty-free allowance is USD $800 per person after 48+ hours abroad; $200 after less than 48 hours.
  5. CBP officer grants clearance. You will receive a verbal clearance or CBP confirmation number. Record it. You are now free to proceed.
  6. User Fee Decal: Foreign-flagged vessels (including Canadian boats) entering US waters must display a valid CBP User Fee Decal (annual fee ~$25). US-flagged vessels returning from Canada do not need this, but Canadian boats visiting the US do.

CBP One App & SVRS

CBP One App — the primary tool for small vessel border crossings. Download before departure from Canada. Allows advance notification, crew/passenger manifest submission, and streamlined processing. Available free on iOS and Android. Especially important for Pacific Northwest crossings where cell service may be limited — submit your report before entering areas with poor coverage.

SVRS (Small Vessel Reporting System) — telephone-based alternative for areas without cell service; pre-register your vessel at cbp.gov. Particularly useful for remote Great Lakes crossings.

US Duty-Free Allowances (Per Person)

  • After 48+ hours in Canada: USD $800 duty-free per person in goods
  • After less than 48 hours: USD $200 per person
  • Alcohol (after 48+ hours): 1 liter (33.8 oz) duty-free per person 21+
  • Tobacco: 200 cigarettes (1 carton) and 100 cigars per adult
  • Cuban cigars: Can bring Cuban cigars back (unlimited for personal use) — this changed in 2016
  • Food: Generally unrestricted for personal use; declare everything; CBP agricultural inspectors may examine
  • Currency: No limit on amount; amounts over USD $10,000 must be declared on FinCEN 105 form
  • Gifts: Included in the duty-free allowance; items over limit are subject to duty
  • Prescription medications: Bring original labeled containers and a doctor’s note if carrying significant quantities

📄 Documents Required Beyond Your Passport

Your passport is the starting point — every person on board must have a valid passport, not a passport card (the passport card is only valid for land and sea crossings at designated land ports — verify its acceptance with CBP and CBSA for your specific crossing route). These are the additional documents you need:

For the Vessel

  • US Coast Guard Documentation or State Registration — proof of ownership and registration for your vessel; the Certificate of Documentation (CG-1270) or state registration card; CBSA and CBP both may ask for this
  • Vessel insurance card or policy — not legally required by either country for pleasure craft, but practically essential; some Canadian marinas require proof of insurance before allowing you to dock
  • FCC Ship Station License — required if your boat has a VHF radio and you are departing US waters (technically required for international voyages; see our VHF Radio Guide); NOT required for purely domestic US sailing but IS required when going to Canada
  • Ship’s radio call sign — issued with your FCC Ship Station License; enter it into your MMSI registration
  • Canadian Pleasure Craft Licence — only required if your boat is Canadian-registered; US boats need their US documentation/registration, not a Canadian licence

For US Boats Visiting Canada

  • No special Canadian import permit required for US pleasure craft visiting for less than 12 months — your vessel is admitted temporarily under the Customs Tariff
  • Do not leave the boat in Canada when you return to the US by air or ground, unless you have arranged a Vessel Importation permit with CBSA — this is a common mistake that creates significant problems

For Each Person Aboard

  • Valid passport (book preferred) — must be valid for the entire duration of your stay; some countries require 6-month validity beyond your intended stay date; Canada and US generally do not require this but it is good practice
  • NEXUS card — optional but extremely useful (see the NEXUS section below); speeds up processing significantly at many crossings
  • Birth certificate + photo ID — for US citizens, this combination is technically acceptable for some land border crossings but NOT acceptable for pleasure boat crossings — you need a passport for a boat crossing
  • Crew/passenger manifest — both CBSA ROAM and CBP One require you to list all persons aboard; have full legal names, dates of birth, citizenship/nationality, and passport numbers ready for everyone
  • Visa (if applicable) — citizens of many countries need a Canadian eTA (Electronic Travel Authorization) to enter Canada, or a US visa to enter the US; verify requirements for any non-US/Canadian nationals aboard before departure
  • For minors traveling without both parents: A notarized letter of consent from the absent parent(s) is strongly recommended and may be required by border officers

Pets

  • Dogs and cats entering Canada: Must have a current rabies vaccination certificate from a licensed veterinarian showing vaccine type, date administered, and duration of protection. A certificate less than 30 days old may not be accepted.
  • Dogs entering the US from Canada: Must be accompanied by a valid rabies certificate; dogs must appear healthy
  • Exotic animals, birds, reptiles: Subject to strict import/export controls under CITES; research requirements well in advance

⛔ What NOT to Bring — Restricted & Prohibited Items

Firearms entering Canada: Read this carefully. Canada has strict firearms laws that are fundamentally different from the United States. Bringing an undeclared firearm into Canada — including a handgun left in a drawer you forgot about — is a criminal offence that can result in arrest, seizure of your vessel, and permanent inadmissibility to Canada.

Into Canada from the US

  • Handguns and prohibited firearms: Handguns are prohibited in Canada for non-residents in virtually all practical circumstances. If you have a handgun aboard, it cannot enter Canada. Full stop. Arrange secure storage in the US before you cross.
  • Rifles and shotguns: Non-prohibited long guns (rifles/shotguns) can be brought to Canada by non-residents under specific conditions (hunting, competition). You must declare them on a Non-Resident Firearm Declaration (Form RCMP 5589). A fee is charged. The declarant must be 18+. This is not recreational — bringing a firearm “just in case” is not accepted.
  • Cannabis: Despite being legal in Canada, it is illegal to bring cannabis across any Canadian border in either direction. This includes CBD products containing THC above the legal threshold. Do not bring it. CBP and CBSA both enforce this.
  • Pepper spray: Many formulations sold in the US as “pepper spray” are prohibited in Canada because of their capsaicin concentration. Bear spray designed specifically for bears is generally permitted. Check the label and CBSA regulations.
  • Alcohol above duty-free: 1.14 litres spirits OR 1.5 litres wine (2 bottles) OR 8.5 litres beer (24 cans) per person 19+ (18+ in Alberta/Manitoba/Quebec). More can be brought but duty and provincial taxes apply — declare it.
  • Certain food items: Fresh fruits and vegetables, meats, and dairy may be restricted depending on origin. Canadian Food Inspection Agency rules apply. Declare all food. Processed and commercially packaged foods are generally fine.
  • Plants, soil, and wood: Subject to CFIA inspection; some items prohibited to prevent spread of invasive species and plant disease

Into the US from Canada

  • Cannabis (any form): Completely prohibited. Legal in Canada, but crossing an international border with cannabis is a federal crime in the US regardless of your destination state’s laws. Do not bring it back.
  • More than $10,000 cash without declaration: Legal to carry but must be declared on FinCEN 105; failure to declare is a seizure-level offense
  • Certain agricultural products: Some fresh fruits, vegetables, and meats restricted or prohibited; CBP agricultural inspectors take this seriously. Generally safe: commercially manufactured food with original labels
  • Counterfeit goods: Any counterfeits of trademarked US products are seized; this includes cheap knockoff merchandise
  • Goods above the duty-free allowance without declaring: CBP will seize undeclared dutiable goods; the penalty far exceeds the duty you would have paid
  • Invasive species and organisms: Bringing Canadian freshwater (bait fish, live bait, even water in your bilge) into the US Great Lakes is subject to inspection and restriction due to invasive species concerns. Drain and dry your dinghy, dinghies, and equipment before crossing.
  • Certain prescription drugs: US-controlled substances purchased in Canada without a US prescription may be seized; always carry original labeled US prescription bottles
The golden rule for both directions: “When in doubt, declare it.” Border officers generally respond well to honest declaration. Attempting to conceal items — even accidentally — can end your cruising trip and your ability to cross this border again.

🌊 Pacific Northwest — Seattle / Puget Sound to British Columbia

The Pacific Northwest border crossing — from Puget Sound, the San Juan Islands, or Bellingham into the Gulf Islands and BC coastal waters — is one of the most popular and well-developed pleasure boat crossings in North America. The infrastructure is good, the scenery is world-class, and both CBSA and CBP have well-established procedures for the large volume of pleasure craft that cross here seasonally.

Key Pacific Northwest Ports of Entry

Into Canada (CBSA)

  • Bedwell Harbour (South Pender Island) — The premier US-to-Canada crossing port for Pacific Northwest sailors; directly accessible from the San Juans or Bellingham; fuel dock, marina; CBSA officer on site during season; resort facilities
  • Port Sidney Marina (Sidney, BC) — Convenient for crossing from Anacortes or Friday Harbor; full marina services; close to Victoria and the Gulf Islands
  • Victoria (Inner Harbour / Ship Point) — Multiple reporting options; customs dock at Ship Point; city amenities immediately available
  • Nanaimo (Port of Nanaimo) — For crossings from the northern San Juans or direct from Port Townsend; central Vancouver Island base
  • Ganges, Salt Spring Island — Gulf Islands reporting location; confirm seasonal hours; call CBSA before relying on this location

Into the US (CBP)

  • Friday Harbor, San Juan Island — Primary reporting port for boats returning from the Gulf Islands; CBP office at the marina; fuel available
  • Roche Harbor, San Juan Island — Telephone reporting; no CBP officer on site but phone reporting is accepted; convenient for Roche Harbor marina guests
  • Point Roberts, WA — US exclave on a BC peninsula; CBP office; good fuel stop; slightly out of the way but useful for specific routes
  • Anacortes, WA — Full services; CBP reporting; excellent base for San Juan Islands and Gulf Islands cruising
  • Bellingham, WA — Squalicum Harbor; CBP reporting available; northernmost significant US marina on Puget Sound

Pacific Northwest Specific Notes

🌊 Great Lakes — US to Ontario/Quebec Crossings

Great Lakes border crossings are fundamentally different from Pacific Northwest crossings in several important ways: the lakes themselves are very large and can produce ocean-like conditions, the crossing points are widely spread, and the infrastructure for pleasure boat customs reporting is less concentrated than in the Gulf Islands. Planning is essential.

Key Differences from Pacific Northwest

The I-68 Canadian Border Boat Landing Permit is a Great Lakes-specific CBP program that allows pre-approved Canadians and their vessels to make multiple entries into US Great Lakes waters without individual reporting at each crossing. It is not available to US vessels or non-Canadian nationals. US vessels returning from Canada must still report to CBP individually. Canadian boaters: apply at cbp.gov.

Into Canada (CBSA — Great Lakes)

  • Kingston, ON (Confederation Basin) — Lake Ontario’s primary sailing city; CBSA reporting; excellent marina facilities; historic waterfront
  • Toronto, ON — Multiple marina options; phone/ROAM app reporting; confirm current designated locations with CBSA
  • Windsor, ON — Detroit River crossing; convenient for Lake St. Clair and Lake Erie sailors from the Michigan/Ohio side
  • Fort Erie, ON — Niagara River; Lake Erie to Lake Ontario connection via the Welland Canal (requires advance planning — not accessible by sailboat above a certain mast height without stepping the mast)
  • Port Colborne, ON — Lake Erie end of the Welland Canal; reporting for boats entering from US Lake Erie ports
  • Sault Ste. Marie, ON — Soo Locks; Gateway between Lake Huron and Lake Superior; CBSA reporting for trans-lake passages

Great Lakes Specific Considerations

  • Welland Canal: The 43-km canal with 8 locks bypasses Niagara Falls and connects Lake Erie to Lake Ontario. Maximum air draft ~35.5m (117 ft). Canal requires advance booking and transit fees. Your mast height determines whether you can transit without stepping.
  • Trent-Severn Waterway: Connects Lake Ontario (Trenton) to Georgian Bay (Port Severn); 386 km; 44 locks; seasonal; Parks Canada permit required; maximum LOA and beam restrictions apply. Plan 7–14 days for the full transit.
  • Lake Superior considerations: The largest lake in the world by surface area can generate storm waves exceeding 20 ft; crossing Superior requires serious offshore preparation and weather timing — treat it like an ocean passage
  • Invasive species wash-down: Many Great Lakes ports on both sides require inspection for invasive species (zebra mussels, milfoil); some require wash-down before launching if you have been in other water systems
  • SVRS (Small Vessel Reporting System): The CBP telephone program is particularly important in the Great Lakes where CBP offices are widely spaced; pre-register your vessel at cbp.gov
  • Lake Champlain: Technically not a Great Lake but a similar border lake situation (NY/VT border with Quebec); similar CBP/CBSA procedures apply; Richelieu River connects to the St. Lawrence; US/Canada border crosses the lake

⚡ NEXUS Card & Trusted Traveler Programs

What Is NEXUS?

NEXUS is a joint US–Canada Trusted Traveler Program that pre-approves low-risk travelers for expedited border crossing by land, air, and marine. For sailors who regularly cross between the two countries, NEXUS is one of the best investments you can make.

  • Cost: Free as of 2024 (previously $50/5 years)
  • Validity: 5 years
  • Eligibility: US and Canadian citizens and permanent residents who pass background checks by both CBP and CBSA
  • Application: Apply online at cbp.gov/travel/trusted-traveler-programs/nexus; interview required at a NEXUS enrollment center
  • Marine benefit: NEXUS members can report small vessel crossings by telephone to a NEXUS-specific line rather than the standard CBSA/CBP phone lines, often with shorter wait times and streamlined processing
  • Also works for: Airline NEXUS lanes (PreCheck equivalent); land border NEXUS lanes

CANPASS Private Boats

CANPASS Private Boats is a CBSA pre-approval program specifically for pleasure vessels that regularly cross into Canada. Approved vessels can report by phone with streamlined processing at many Pacific Northwest reporting locations.

  • Apply through CBSA; all people who regularly travel on the vessel must be approved
  • Valid for the vessel, not just the owner — crew members must be individually enrolled
  • Particularly useful for Pacific Northwest sailors who cross multiple times per season
  • More information: CBSA CANPASS Private Boats

Global Entry

  • Global Entry is a US-only program (not bilateral like NEXUS) for expedited US customs when entering the US internationally; includes TSA PreCheck
  • Less useful for marine crossings than NEXUS since it doesn’t cover Canadian side
  • If you already have Global Entry, you do not need NEXUS for PreCheck but NEXUS is better for regular US-Canada crossings
