Crossing the border from Vancouver: NEXUS, the train and trips to Seattle

Living in Vancouver puts Seattle, Bellingham and a Trader Joe's run close enough for a day trip. NEXUS, a little planning and knowing the duty-free rules make the border part painless.

The short version

• Four car crossings serve Metro Vancouver. Peace Arch and Pacific Highway are closest, about 45 km (28 miles) from downtown. Lynden–Aldergrove and Sumas–Abbotsford are farther east.
• NEXUS costs USD 120 for five years, and kids under 18 are free [1]. It gets you dedicated lanes both ways, faster airport entry and possible TSA PreCheck [2].
• Amtrak Cascades runs two daily round trips between Vancouver and Seattle. Since June 8, 2026, US customs clears you at Pacific Central Station before departure [5].
• Coming back to Canada: no duty-free allowance for same-day trips, CAD 200 after 24 hours and CAD 800 after 48 hours [3].
• Going into the US: CBP's returning-resident allowance is USD 800, or USD 200 if you've been away less than 48 hours [4]. If you live in Canada, ask how CBP treats you.

Which crossing to use

Here's a quick lay of the land, with rough distances from downtown Vancouver:

The Peace Arch itself sits in a park that straddles the line. It's worth a stop once, with the Fourth of July and Canada Day both celebrated within a few days of each other.

Wait times

Waits swing a lot. Weekday mornings can be a breeze, while a long weekend southbound can feel like Black Friday at the outlet mall. Both border agencies post live wait times, and BC and Washington show them on highway signs. Check before you pick a crossing. Canadian long weekends (Victoria Day, BC Day, Thanksgiving in October) and US holidays (Memorial Day, Thanksgiving in November) can both jam things up in different directions.

NEXUS: the best USD 120 you'll spend here

NEXUS is the joint US–Canada trusted traveler program, run by US Customs and Border Protection (CBP) and the Canada Border Services Agency (CBSA). US citizens qualify, and so do Canadian citizens and permanent residents.

1. Apply online through CBP's Trusted Traveler Programs system and pay the USD 120 nonrefundable fee [1]. Children under 18 are free, but each person needs their own card.
2. Wait for conditional approval from both countries. This can take a while.
3. Book an interview at an enrollment center. Recent rules tie how long you have to schedule to when you were conditionally approved. CBSA's temporary extension ends April 1, 2027, and after that you'll have two years from approval to schedule [1].
4. Get your card in the mail. Membership lasts five years [1].

What you get [2]:

• NEXUS lanes at land crossings into both countries. The Peace Arch, Pacific Highway and Sumas crossings have them.
• NEXUS kiosks at Canadian airports and Global Entry kiosks entering the US, including at the US preclearance area at YVR.
• Possible TSA PreCheck for US citizens.

Everyone in the car needs NEXUS to use the lane. One family member without a card means the regular line for all of you.

The train: Amtrak Cascades

The Cascades runs from Vancouver's Pacific Central Station to Seattle's King Street Station, with stops including Bellingham and Everett. There are two daily round trips [5].

The big 2026 news: since June 8, 2026, US customs screening happens at Pacific Central Station before you board, so the train no longer stops at the border in Blaine. Arrive an hour early. The trip to Seattle is scheduled at about 4 hours 15 minutes southbound and 4 hours northbound [5]. Freight traffic can still slow things down.

It's not faster than driving on a good day, but you skip the parking hassle and the I-5 traffic around Everett, and there's a café car.

Flying: YVR, Bellingham or Sea-Tac?

Lots of Vancouver Americans fly to US cities from south of the border:

• YVR has US preclearance, so you clear US customs before you board and land as a domestic passenger. It's convenient, but fares are often higher.
• Bellingham (BLI) is about 90 km (56 miles) from downtown Vancouver, just past the border. It has a smaller list of US destinations, often at lower fares.
• Seattle–Tacoma (SEA) is about 250 km (155 miles) away and has the most nonstop flights. Factor in the border, the drive and parking.

Build a buffer for the border on your way to BLI or SEA. A 30-minute wait can turn into two hours on a sunny Saturday.

Duty-free limits: coming back to Canada

If you live in Canada, you're a returning resident when you come back. That includes Americans here on work or study permits [3]. CBSA's personal exemptions:

USD conversions use the Bank of Canada rate of 1.3989 CAD per USD (November 5, 2026).

Exemptions can't be combined or shared. The alcohol limit after 48 hours is one of these: 1.5 liters of wine, 1.14 liters of spirits or 8.5 liters of beer, about 24 cans [3]. You need to be 19 to bring alcohol in through BC.

So a Costco run to Bellingham and back the same day means paying GST and any duty on everything you declare. Plenty of people still find it worth it for some items, but declare honestly. Undeclared goods can be seized.

Duty-free limits: going into the US

CBP's standard exemption for returning US residents is USD 800 in goods that travel with you. It drops to USD 200 if you've been out of the US less than 48 hours or already used the exemption in the past 30 days [4]. The fine print: those allowances are written for US residents. As an American living in Canada, you may be treated as a nonresident, which comes with a much smaller gift allowance. When in doubt, declare and ask the officer.

A few things that cause trouble at this border:

• Cannabis. It's legal in BC and in Washington, but carrying it across the border in either direction is illegal. Leave it home.
• Fresh food. Fruit, vegetables and some meats can be refused either way. Declare them.
• Your documents. Bring your US passport (or NEXUS card at land crossings) and, coming back to Canada, your PR card or valid permit.
