Cross-border container shipping between Canada and the US is done either by bonded truck (a drayage or long-haul carrier with authority in both countries) or by rail (CN and CPKC run directly into the US), with customs data filed electronically in advance on both sides. The best cross-border carrier is one that has US and Canadian authority, bonded capability, experienced drivers and a customs broker relationship.
Key takeaways
- Carriers need authority in both countries, a US DOT number and a Canadian safety certificate, plus insurance that covers the US.
- Advance electronic data is mandatory: ACI eManifest into Canada and ACE eManifest into the US.
- PARS (Canada) and PAPS (US) barcodes link the freight to the customs entry.
- CUSMA-qualifying goods avoid most duties, but the 2025 tariff disputes and the 2026 CUSMA review mean rules can change. Check current guidance before each season.
Common cross-border container routes

How the process works
- Book a carrier with cross-border authority.
- Your customs broker prepares the entry for the destination country.
- The carrier files the eManifest (ACI for Canada, ACE for the US) before arrival.
- PARS/PAPS labels are attached to the paperwork.
- Border crossing: the driver presents documents; the freight is released or held for inspection.
- Delivery to the consignee, or to a bonded warehouse if clearance happens inland.
What to look for in a cross-border carrier
| Check | Why it matters |
|---|---|
| US DOT and MC numbers + Canadian safety certificate | Legal authority in both countries |
| Bonded carrier status | Moving goods in bond before duties are paid |
| FAST / C-TPAT / PIP membership | Faster border processing |
| Insurance valid in the US | Claims coverage on US roads |
| Drivers with FAST cards | Using FAST lanes at the border |
| Customs broker relationships | Fewer delays from missing documents |
Tariffs and CUSMA in 2026
In 2025 the US and Canada imposed tariffs and counter-tariffs on a range of goods, and many measures changed several times during the year. Goods that qualify under CUSMA (USMCA) rules of origin were treated differently from non-qualifying goods. The formal CUSMA joint review in 2026 may bring more changes.
What to do:
- Confirm your goods' tariff classification and origin with your customs broker.
- Keep certification of origin documents ready.
- Check the latest CBSA and US Customs and Border Protection notices before booking.

Frequently asked questions
What is ACI eManifest?
It is CBSA's system for carriers to send cargo and conveyance data electronically before freight arrives in Canada.
What is the difference between PARS and PAPS?
PARS (Pre-Arrival Review System) is used for goods entering Canada. PAPS (Pre-Arrival Processing System) is used for goods entering the US.
Do Canadian carriers need a US DOT number to cross the border?
Yes. Carriers operating in the US need a USDOT number and, for most for-hire work, operating authority.
Does CUSMA remove all duties between Canada and the US?
CUSMA removes duties on goods that meet its rules of origin, but other measures such as specific tariffs can still apply. Check with your customs broker.
Can containers cross the border by rail?
Yes. CN and CPKC both run rail services between Canada and the US, and many containers from Prince Rupert and Vancouver travel to the US Midwest by rail.
