Every commercial carrier hauling freight into Canada must file an ACI eManifest with CBSA at least 1 hour before arrival, or face refused entry, fines, and border delays. This 2026 guide covers the ACI requirements, mandatory data fields, deadlines, common rejections, and the fastest way for highway carriers to stay compliant.
What Is the ACI eManifest Program?
ACI is the CBSA's electronic reporting system for advance cargo information. It is the Canadian equivalent of the US ACE system. Under ACI, carriers must electronically transmit shipment and conveyance data to the CBSA before the truck arrives at a Canadian port of entry.
The program was introduced to improve border security and speed up the clearance process. Since its full implementation, paper manifests are no longer accepted for highway commercial shipments entering Canada.
Who Must Comply with ACI Requirements?
ACI filing is mandatory for:
- US carriers transporting commercial goods northbound into Canada
- Canadian carriers returning to Canada with picked-up freight
- Freight forwarders who act as the carrier of record
- Owner-operators crossing with any commercial shipment
If you are hauling goods across the border into Canada by truck, you must file an ACI eManifest. There are no exemptions based on shipment size or value for highway carriers.
Required Data Fields for ACI eManifest
The CBSA requires three categories of advance data, each with specific mandatory fields:
Conveyance Data
- Carrier code (assigned by CBSA)
- Truck license plate number and country/state of registration
- Trailer license plate number (if applicable)
- Expected port of entry
- Estimated date and time of arrival
- Driver information
Crew/Driver Data
- Full legal name as it appears on travel documents
- Date of birth
- Citizenship
- Travel document type and number (passport, FAST card, or NEXUS card)
Shipment Data
- Shipper name and complete address
- Consignee name and complete address
- Description of goods (must be specific enough for CBSA to identify the commodity)
- Number of pieces and weight
- PARS number (Pre-Arrival Review System barcode)
- Customs broker information
- Port of exit from the US (if applicable)
ACI Filing Timing Rules
Timing is critical for ACI compliance. The CBSA has strict advance filing deadlines:
- Highway shipments -- the eManifest must be transmitted and accepted at least one hour before the truck arrives at the Canadian port of entry
- Amendments -- if any data changes after filing (different driver, trailer swap, additional shipment), the manifest must be amended and re-accepted before arrival
- Close message -- carriers must send a "close" message to indicate the manifest is complete and the truck is en route
The one-hour rule is a hard minimum. Many experienced carriers file several hours or even a full day in advance to ensure there is time to resolve any issues.
Penalties for ACI Non-Compliance
The CBSA takes eManifest compliance seriously. Penalties for violations include:
- First offense -- a warning letter and potential hold at the border
- Subsequent offenses -- monetary penalties starting at $2,000 CAD per violation, escalating with repeat offenses
- Refused entry -- trucks that arrive without a filed and accepted eManifest can be turned away at the border entirely
- Carrier audit -- repeated non-compliance can trigger a full CBSA audit of your operations, which can lead to additional fines and restrictions
Beyond the direct penalties, border delays caused by compliance failures cost carriers real money in driver hours, missed delivery windows, and damaged customer relationships.
Common ACI Compliance Pitfalls
- Incorrect PARS numbers -- the PARS barcode must exactly match what the customs broker has transmitted to the CBSA
- Generic cargo descriptions -- "freight" or "goods" will be rejected; you need specific descriptions like "automotive brake pads" or "frozen chicken thighs"
- Outdated driver documents -- if a driver's FAST card has expired or their passport number has changed, the manifest will not match at the booth
- Missing close message -- forgetting to send the close message means the CBSA does not know your truck is en route, which can cause processing delays
- Last-minute trailer changes -- swapping trailers without updating the manifest is one of the most common causes of border holds
