CBSA's ACI Reminder Isn't New — But the System Context Behind It Is

The TCC Is Boilerplate. The Timing Isn’t.

TCC26-0089 went out last week reminding carriers and freight forwarders that house bill transmission and house bill close messages are mandatory under ACI. If you’ve been in the industry more than six months, none of that is news. What matters is why CBSA felt the need to restate it now, in the middle of acknowledged system delays and ongoing CARM stabilization work.

This isn’t a new rule rollout. It’s enforcement signalling. When CBSA issues a reminder during a period of system chaos, it means they’re seeing non-compliance patterns they’re about to start actioning — or they’re pre-positioning before penalties resume after a grace period wind-down. Either way, if your forwarder has been loose with close messages or your drayage carrier has been skating by on partial ACI filings, that window is closing.

What Actually Happens When ACI House Bills Aren’t Closed

The mechanics are straightforward but the operational fallout isn’t always obvious until you’re stuck in it. ACI requires the house bill to be transmitted pre-arrival (highway/rail/air) or pre-load (marine), and then a house bill close message once the manifest is finalized. No amendments after close without a proper change transmission.

When close messages don’t get sent — or get sent late, or with mismatched data — you get:

• Cargo holds at first point of arrival, especially at high-volume crossings like Pacific Highway or Lacolle where CBSA has less tolerance for manual intervention.
• RMD and PARS release workflows that stall because the eManifest chain isn’t complete. Your CAD might be clean, duties posted to the CARM client portal, but if the conveyance record shows an open house bill, the driver sits.
• Increased examination rates. Incomplete ACI data flags risk scoring algorithms. You might have a 99.9% release-on-arrival history, but if the manifest is messy, you’re getting sent to bay.

The reminder specifically calls out house bill close messages. That’s the step that gets missed most often, especially by smaller forwarders or when shipments get re-consolidated at a Canadian gateway. If your freight is moving through a bonded warehouse in Montreal — say, a sufferance facility handling deconsolidation — and the original house bill from overseas isn’t properly closed before the domestic leg starts, you’ve just introduced a two-day delay minimum while everyone sorts out who owns the correction.

CBSA Systems Are Still Fragile Post-CARM

CBSA acknowledged in the same notice that they’re experiencing “ongoing system delays” and working on stabilization. That’s careful language. Translation: CARM Portal performance is still inconsistent, there are latency issues between the portal and legacy release systems, and somewhere in the chain between eManifest, the CAD repository, and whatever they’re using for internal workload management, things are dropping.

We’ve seen this play out since CARM go-live last October. Posting a CAD at 8 a.m. doesn’t guarantee it surfaces in the officer’s queue by noon. Sometimes it takes six hours. Sometimes it doesn’t show up until someone manually pulls it. The CBSA’s own CARM updates page has been rolling out incremental fixes monthly, but the underlying architecture still isn’t where it needs to be for the transaction volumes we’re running.

So when CBSA says “we would like to remind trade chain partners” of ACI obligations, part of that is deflection. They know their systems are creating friction. They also know that incomplete ACI data makes that friction exponentially worse. If the eManifest feed is clean, their back-end has a fighting chance. If it’s messy, the whole thing grinds.

Who This Actually Lands On

The TCC is addressed to carriers and freight forwarders, but compliance responsibility doesn’t stop there. If you’re the importer of record and you’re relying on a forwarder who isn’t closing house bills properly, you are the one sitting on demurrage while CBSA sorts it out. Your terms of sale don’t insulate you from the operational hit.

Most mid-market importers don’t have direct visibility into whether their forwarder is ACI-compliant. You see the shipment move, you see the delivery appointment, and if there’s a problem, you get a vague “customs delay” message. Start asking your freight forwarder for ACI transmission confirmation as part of standard shipment updates. If they can’t or won’t provide it, that’s a red flag.

Same thing if you’re using your own bonded carrier or a drayage provider that isn’t integrated with your broker. The ACI house bill has to match the CAD. If your broker files under one FIRMS code and the carrier transmits under another, or if there’s a mismatch between the house bill weight and the CAD line-level detail, you’ve just bought yourself a manual review cycle.

Enforcement Is Coming, Just Slowly

CBSA has been in a semi-official grace period since CARM launch. Penalties for late CAD filings have been lighter than the regulations technically allow, examination rates have been selectively dialed back to avoid port gridlock, and administrative monetary penalties (AMPs) for ACI non-compliance have been mostly warnings.

That’s changing. TCC26-0089 is one signal. The other is that we’re starting to see AMP notices land for ACI violations that happened in Q4 2024, which means CBSA’s enforcement backlog is clearing and they’re working back through the queue. If you had close message failures between October and December and didn’t get dinged at the time, don’t assume you’re clear. The penalty notice might show up in your CARM portal next month.

For what it’s worth, house bill close message violations typically run $250 to $1,000 per occurrence for first-time offenders, scaling up for repeat issues. Not business-ending, but it adds up fast if your forwarder is filing twenty shipments a week and half of them have ACI issues.

What To Do This Week

Pull your last thirty days of shipments and confirm that every house bill was closed. If you don’t have that visibility, your broker or forwarder should. If they can’t produce it quickly, you’ve got a compliance gap worth addressing.

If you’re working with a small or non-integrated forwarder, now’s the time to pressure-test their ACI workflow. Ask them what system they use for eManifest transmission, how they handle close messages, and what their error rate looks like. If the answer is “we submit everything manually” or “our software does it automatically,” neither is good enough. You want specifics.

And if you’ve been handling your own freight coordination because rates are better or lead times are shorter, make sure whoever is filing the ACI is actually competent. Cheap drayage is expensive if it comes with a three-day border hold.
