Frequently asked questions

Which highways connect Canada and the United States for trucking?

The five corridors above: Interstate 5 to BC Highway 99 at the Pacific coast, the Interstate 95 corridor into New Brunswick, Interstate 81 and Interstate 87 into Ontario and Quebec, the Interstate 75 corridor through Detroit and Windsor to Highway 401, and Interstate 15 to Alberta Highway 4 at Coutts and Sweet Grass. Each pairs one US interstate with one Canadian provincial highway at a commercial crossing.

What paperwork does a truck need to cross the border?

An ACE e-manifest for US-bound freight and an ACI e-manifest for Canada-bound freight, each on file before arrival, plus the customs broker's entry and the commercial documents for the load. A TMS with an ACE and ACI e-manifest module files both from the load record, so customs data is never keyed twice.

How does a TMS help plan cross-border routes?

It keeps the crossing, broker details and documents on the load, bills the US customer in USD and the Canadian one in CAD off the same trip, and produces the IFTA report (Enterprise plan) from the miles by jurisdiction. See TMS software built in Canada for cross-border fleets for how the pieces fit on one load record.
