The short answer

Pick the crossing before dispatch and give it to both the customs broker and the carrier, because it becomes the first port of arrival in the carrier's eManifest report and the place a non-bonded carrier must get release. Weigh commercial access, broker coverage, current wait times, road restrictions, weather and, for oversize loads, the crossing's physical limits. The shortest map route is not automatically the right port.

How the crossing fits the move

For a load into Canada, the crossing is the first port of arrival. The carrier's cargo and conveyance data name it; the customs broker's release request is reviewed for it; and a non-bonded carrier must have its goods released there. Change the port on the day and every one of those has to be updated.

Southbound, the same is true of the first U.S. port in the carrier's CBP e-manifest.

What decides the port

  • actual pickup and delivery locations
  • commercial truck access and hours
  • where the broker can process release
  • carrier preference and experience
  • bridge, tunnel and road restrictions
  • commodity programs (some goods clear only at certain ports)
  • oversize limits when the load is over-dimension

Major commercial corridors include Detroit–Windsor, Port Huron–Sarnia, Buffalo/Niagara, Champlain–Lacolle, Blaine–Surrey (Pacific Highway) and Pembina–Emerson, among others. We do not publish a "best crossing" ranking: hours, construction and congestion change. Check current commercial wait times on the day.

After the border

Build the delivery appointment around the whole day: the drive to the port, the commercial queue, possible examination, any document correction, the driver's remaining hours and the distance from the border to the consignee. A 10:00 arrival at the port does not mean a 10:30 delivery on the other side.

Many Canada lanes run through heavy winter weather. Check forecasts, road conditions, seasonal load restrictions and construction on the travel day.

Oversize changes the question

For an oversize load, the crossing has to work physically (bridge and tunnel clearances, weight limits, inspection-area geometry) and legally under the U.S. state permits before it and the provincial permits after it. A legal standard truck route may not be a legal oversize route. See oversize freight to Canada.

Common failure points

  • The driver picks the port that looks shortest on the day.
  • The broker expects one port and the carrier's report names another.
  • Delivery is booked as though the crossing takes no time.
  • An oversize load is routed to a crossing it cannot use.

Before requesting a quote

  • Pickup and delivery, with postal codes
  • Ready date and delivery window
  • Equipment, dimensions and weight
  • Standard or oversize
  • Customs broker and where it processes release
  • Preferred crossing, if already set
  • Importer readiness
  • Receiver hours and restrictions

Common questions

Should the closest crossing always be used?

Not always. It has to suit the broker, the carrier, the commodity, the road restrictions and the delivery timing.

Where are current commercial wait times?

CBSA and CBP both publish border wait times, including the commercial flow at major crossings.

Does the Route Planner choose the crossing?

No. Our Route Planner maps the drive (it uses car routing) so you can see distance and time. The crossing is confirmed with the broker and carrier.

Need the crossing built into the plan?

Send the lane, freight and customs broker, and we will treat the crossing as part of the transportation plan.
