The Michigan-Ontario freight lane

The Michigan-to-Ontario lane reverses the busiest commercial corridor in North America. Detroit-metro stamping, engine, and transmission plants ship parts north to Ontario assembly at Oakville, Oshawa, Cambridge, and Ingersoll. Finished vehicles and cross-plant JIT components dominate. Most northbound volume uses the Ambassador Bridge; Blue Water Bridge handles hazmat, oversized, and overflow. FAST-enrolled drivers save the most time on this lane — ACI FAST lanes exist at both primary crossings.

Filing ACI on this lane

ACI eManifest must be transmitted and accepted by CBSA at least one hour before arrival. A PARS barcode should be affixed if the broker will clear the load. For this lane, carrier-to-broker RNS cycles are short — a PARS not showing as matched 15 minutes out typically indicates a data error worth calling about before the truck reaches the plaza.
