If you move commercial freight into Canada by truck, ACI/eManifest is not just “another customs acronym.” It’s the dataset CBSA expects to see before your tractor hits the primary booth. And when it’s done right, it’s one of the most predictable parts of the trip: you file, you get accepted, you print a lead sheet, and your driver shows up with a clean story that matches what CBSA already has on-screen.
When it’s done wrong, it doesn’t matter how fast your driver is or how tight your appointment window is. A small mismatch (wrong trailer plate, wrong CCN/CRN, “general freight” cargo description, consignee address that doesn’t match the commercial invoice) can turn into a rejection, a phone call to the broker, or a secondary referral you didn’t budget time for.
1) What ACI/eManifest is (and what it isn’t)
CBSA calls eManifest a modernization initiative designed to get “the right information at the right time” so the agency can identify potential threats while still facilitating low-risk shipments. It’s also described as the third phase of the Advance Commercial Information (ACI) program, expanding pre-arrival electronic reporting across modes including highway.
In plain terms: ACI/eManifest is CBSA’s pre-arrival data requirement for commercial shipments. It connects your trip, your equipment, and your shipment data to a reference number CBSA can retrieve instantly when the driver reports.
If you’re used to U.S.-bound filing, it helps to think of ACI as the Canada-bound counterpart to the U.S. side’s eManifest habits — but with its own vocabulary and document structure. For example, you’ll see:
- CCN (Cargo Control Number) — the shipment identifier used in the Canadian system.
- CRN (Conveyance Reference Number) — the trip/equipment reference that links one or more CCNs.
- Lead sheet — the printed (or printable) sheet that contains bar-coded data elements CBSA officers scan to pull up the manifest quickly.
One more distinction that surprises people: CBSA notes that shipments qualifying for Customs Self-Assessment (CSA) clearance can be exempt from advance commercial information requirements, and mixed loads can still require advance documents for the non-exempt portion. If you’re not 100% sure whether a load is exempt, treat it as non-exempt until your broker confirms.
2) What the ACI lead sheet does at the border
The ACI lead sheet is the bridge between your electronic filing and your driver’s two-minute border interaction. CBSA’s highway rules require a lead sheet to be presented at the First Port of Arrival, and CBSA describes acceptable lead-sheet content options like a bar-coded CRN, or a bar-coded CCN with a handwritten CRN, or a handwritten CRN if another bar-coded document is also being presented.
Operationally, the lead sheet helps the officer:
- Retrieve the correct conveyance quickly (scan barcode → pull up manifest)
- Confirm the driver and equipment match what was transmitted
- See the linked cargo documents (the CCNs attached to the CRN)
- Move low-risk, complete files through primary without “paper archaeology”
3) What information CBSA expects (highway)
CBSA’s highway ACI/eManifest guidance lays out a long list of data elements, but most dispatch teams can remember it as five buckets: carrier identity, equipment identity, arrival timing, parties, and cargo details. Here’s what that looks like in practice.
Carrier + trip identifiers (the backbone)
- Carrier code and carrier name
- CRN (your trip reference) — unique, carrier-assigned
- First Port of Arrival (FPOA)
- Estimated date/time of arrival and time zone
Equipment details (what CBSA will match at the booth)
- Tractor identifier and tractor plate + country
- Trailer identifier and trailer plate + country (or VIN rules when no plate exists)
- Container identifier (if applicable)
- Seal number when applicable (and yes — this is where good seal discipline pays off)
Cargo details (what the shipment actually is)
- CCN (cargo control number)
- Cargo description that’s specific enough to be risk-assessed
- Packaging type, quantity, and unit of measure
- Total weight and unit of measure
- Marks and numbers
- HS code (when available/required)
Parties (who is shipping to whom)
- Shipper name + address + contact details
- Consignee name + address + contact details
- Notify party / delivery address when relevant
4) A practical filing workflow that reduces rejections
Here’s a workflow that works well for busy cross-border fleets, especially when dispatch and brokerage teams are moving fast.
Step 1 — Lock in shipment facts early
- Confirm consignee and delivery address (including postal code)
- Confirm commodity descriptions (avoid generic phrases)
- Confirm weights and piece counts
Step 2 — Create the ACI cargo document(s)
Whether you file through the CBSA portal, EDI, or a third-party tool, make sure each shipment has a valid CCN and that it matches the paperwork your driver carries.
Step 3 — Link the conveyance (CRN) to the cargo (CCNs)
This is where most “we filed it” stories fall apart. The conveyance has to be linked to the correct cargo documents. If you’re hauling multiple shipments, confirm the full list of CCNs attached to the CRN before you print anything.
Step 4 — Get acceptance and print the lead sheet
CBSA’s highway guidance notes that the portal can print a bar-coded lead sheet for convenience. That’s the version most officers prefer because it scans cleanly and pulls up the right record immediately.
Step 5 — Driver briefing (2 minutes that save 2 hours)
- Lead sheet is in the same folder every trip
- Driver knows which reference numbers matter (CRN and CCN)
- Driver confirms the tractor/trailer plates match what was filed
- Driver confirms the seal number (bolt/cable/plastic) matches the paperwork if used
5) The top mistakes that trigger delays
1) Filing too close to the border
CBSA’s highway rules state that cargo and conveyance documents must be received and validated no later than one hour before arrival at the First Port of Arrival. That’s a deadline, not a suggestion. Build a buffer for rejections and corrections.
2) Mismatched IDs (tractor/trailer plates, VIN rules)
A very common headache: the dispatch team updates a trailer assignment, but the manifest isn’t updated. The officer sees one plate; the system shows another. That mismatch can derail an otherwise clean trip.
3) Weak cargo descriptions
“Parts,” “general merchandise,” and “freight” are fast to type — and slow to clear when an officer can’t risk-assess the shipment from the data. Use specific commodity descriptions that match the commercial invoice.
4) Incorrect consignee or delivery address
Typos and outdated address books cause downstream issues, especially when shipments are destined to sufferance warehouses or inland locations where sublocation codes apply.
5) Broken carrier/broker handshake
The broker can’t fix what they can’t see. And the carrier can’t assume the broker “has it” unless the acceptance status is confirmed. Treat it like a handoff: someone owns “accepted and printed.”
6) Why carriers still use physical lead sheets in a digital world
Drivers still live in a physical environment: the booth, the window, the scanner, the stamp. A digital manifest is great — but at the moment of truth, the driver needs a lead sheet that’s legible, scannable, and consistent.
That’s why many fleets keep a physical pad of lead sheets in the truck even if dispatch can email a PDF. Paper is the fallback when a phone battery dies, a tablet loses service, or a print shop at a truck stop is out of order.
And yes: sometimes the “analog backup” is the difference between a minor delay and a full re-run of the filing.

8) Carrier/broker handshake checklist (copy/paste for dispatch)
- Carrier: confirm tractor/trailer plates and driver details for the trip
- Shipper: confirm commodity descriptions + weights match invoice
- Broker: confirm release strategy aligns (PARS vs other release types)
- Carrier/broker: confirm ACI status = accepted (not just “submitted”)
- Dispatch: print lead sheet and place it with the trip packet
9) How ACI fits with your other border documents
ACI/eManifest rarely lives alone in a trip packet. Most of the carriers we work with run a small family of documents that all have to agree with each other, and the ACI lead sheet is just one piece of that picture. When a driver is standing at the booth, the officer is effectively cross-checking several stories at once: the advance data, the release strategy, and whatever physical documents are riding in the cab. The cleaner those stories line up, the faster everyone gets waved through.
Two documents come up constantly in the same breath as ACI, so it’s worth knowing how they relate.
NCAP / FAST sheets (for trusted-trader lanes)
If your fleet runs the FAST lane under the trusted-trader programs, you’ll still want a clean, scannable lead document for the driver — and that’s exactly what NCAP/FAST sheets are built for. The principle is identical to ACI lead sheets: give the officer a legible, consistent document so the data you transmitted electronically pulls up in seconds. Like our ACI sheets, NCAP/FAST sheets come in two formats — physical pads for daily runners and a digital download for carriers who only need to print on demand. If you’re moving from a general lane into FAST, build the habit now: same folder, same spot, every trip.
A8A in-bond documents (when freight moves under bond)
Not every Canada-bound shipment clears at the first port. When freight has to move in-bond to an inland sufferance warehouse or another CBSA office before release, the A8A (Cargo Control Document) enters the conversation. It’s a different animal from a lead sheet — it controls the movement of goods that haven’t yet been accounted for — but it lives in the same trip packet and has to reconcile with the same cargo control numbers you reported on ACI. BorderPrint stocks the A8A family in all three common variants so dispatch can match the exact workflow: the standard A8A in-bond document, the A8A/B filled-in cargo control document, and the A8A/B with PARS labels for trips that combine in-bond movement with a PARS release. The takeaway for dispatch: if a load is moving in-bond, don’t treat the A8A as an afterthought — the CCN on the A8A and the CCN on your ACI filing need to tell the same story, or you’ll be untangling it inland.

10) FAQ
Do I need ACI/eManifest for every Canada-bound truck shipment?
Most commercial highway shipments into Canada require advance cargo and conveyance data, with limited exceptions. If a shipment qualifies for CSA clearance, CBSA notes that it can be exempt from advance commercial information requirements — but you should confirm with your broker before relying on an exemption.
What is the minimum timing for ACI/eManifest filings?
CBSA’s highway guidance indicates that highway cargo and highway conveyance documents must be received and validated no later than one hour before arrival at the First Port of Arrival.
What should be on the ACI lead sheet?
CBSA describes lead-sheet options including bar-coded CRN, or bar-coded CCN with handwritten CRN, and notes that a bar-coded lead sheet can be printed from the portal for convenience.
