PARS Tracking · CBSA FPOA 0620
Live RNS status, broker cargo feed, and wait-time data for Canada-bound PARS loads crossing Detroit, MI → Windsor, ON.
The Ambassador Bridge is North America's single busiest commercial crossing, carrying roughly one-quarter of all merchandise trade between Canada and the United States. Truck traffic here is dominated by automotive parts, finished vehicles, and just-in-time manufacturing freight moving between southern Ontario and the Detroit metro assembly plants. Because so much of the freight is scheduled to the hour, ACE and ACI timing are less forgiving here than at almost any other crossing on the northern border.
PARS barcodes for Canada-bound loads crossing the Ambassador Bridge are processed at CBSA FPOA 0620. Brokers in Windsor and the Detroit metro transmit RNS status updates on short cycles here, so a PARS that is not RNS-matched 15 minutes out usually signals a broker data mismatch rather than a slow CBSA queue — call your broker before you reach the plaza.
Heaviest US-bound waits land on weekday mornings 6-10am as Detroit assembly shifts start. Canada-bound peaks 3-7pm. Sunday evenings run lighter. The bridge does not close for weather unless winds exceed 60 mph.
The Ambassador Bridge is privately owned — the only privately-owned international bridge on the northern border — which is why tolls and commercial lane configurations can change without the multi-agency review that governs other crossings.
PARS for Ambassador Bridge is typically filed by brokers in Windsor, Tecumseh, LaSalle, Detroit, Dearborn, Livonia. BorderPro pulls RNS updates directly from CBSA and correlates them with your broker's cargo feed — so "sent but not matched" situations are visible in real time, not discovered at the booth.
CBSA requires at least 1 hour of advance data for highway PARS. Most Windsor-area brokers aim for 2+ hours to leave room for cargo amendments before the driver arrives.
Windsor CBSA runs a fast RNS cycle — if you are within 30 minutes of arrival and still have no "matched" status, the usual cause is a mismatch between the broker cargo data and your eManifest (CCN, container number, or weight).
