The Current State
CBSA posted update nineteen on April 29: inbound commercial EDI and eManifest messages are processing with a one-to-three-hour delay, outbound acknowledgements are running six to eight hours behind. That means your ACI transmission goes through within an hour or two, but the response — cargo release notification, exam hold flag, CAD acknowledgement — can sit in the queue for most of a working day.
If you're used to filing a CAD at 10:00 and seeing the release code by noon, you're now looking at 16:00 or later. If your drayage window at the container terminal closes at 15:00, that timeline just became a problem.
Where It Hurts
The delay hits hardest in three spots.
First, PARS and RMD shipments with tight pickup schedules. PARS release prior to payment depends on CBSA sending the cargo release message back to the carrier and the terminal. If that message sits in queue for six hours, the container stays on "hold" status even though you filed clean ACI forty-eight hours before arrival. Terminals don't care that CBSA received your data — they care that CBSA sent the release. A six-hour acknowledgement lag turns a planned morning pickup into an afternoon scramble or a missed appointment entirely.
Second, CAD filing under the five-day accounting deadline. Post-CARM, you have five working days from release to file your Commercial Accounting Declaration and settle duties in the CARM Client Portal. Most brokers file the CAD within twenty-four hours to avoid last-minute portal outages or payment failures. If CBSA takes eight hours to acknowledge the CAD submission, you lose visibility into whether the declaration was accepted, rejected for a missing FIRMS code, or flagged for a tariff classification error. That acknowledgement gap compresses your window to fix problems before the five-day clock expires and AMPS penalties start accruing.
Third, eManifest ACI corrections. If you catch a shipper-supplied HS code error or a missing CUSMA certificate number after the ACI was transmitted, you file an amendment. CBSA normally acknowledges the correction within minutes. Under the current delay, that acknowledgement can take half a day. If the truck is crossing the border in six hours and you're waiting on confirmation that the corrected ACI was accepted, you're filing blind or telling the driver to pull over and wait.
What Doesn't Change
The statutory deadlines haven't moved. Five working days to file the CAD, fourteen days to pay duties if you're not on an RPP bond, thirty days to claim CUSMA preference if you missed it at entry. CBSA processing delays don't extend those windows. The five-day CAD clock starts from the date of release, not the date CBSA sends you the acknowledgement.
The exam and inspection queues are separate. If CBSA flags a shipment for physical examination under SIMA or sends it to CFIA for an organic certificate check, that hold happens regardless of portal message timing. The six-to-eight-hour acknowledgement delay doesn't cause more exams — it just delays your notification that an exam was triggered.
Cargo can still be released. CBSA is processing the data, they're just slow to send confirmations. If your ACI is clean and your importer's CARM account is in good standing, the release will eventually come through. The issue is visibility and timing, not whether release happens at all.
Tactical Adjustments
File earlier. If you normally transmit ACI twelve hours before a truck crosses, push it to twenty-four. If you file CADs same-day as release, file them the morning after and assume the acknowledgement won't arrive until late afternoon. Build the six-to-eight-hour lag into your internal cutoff times.
Use phone and email escalation for time-sensitive corrections. The portal delay doesn't affect the CBSA officer's ability to see your ACI or CAD in their system — it only affects the automated acknowledgement message back to you. If you filed an ACI correction and need confirmation before the truck reaches the border, call the port of entry or the commercial client services line directly. They can verify receipt and acceptance without waiting for the outbound message to clear the queue.
Confirm terminal release status independently. If you're picking up a container in Montreal and filed PARS three hours ago, don't assume CBSA's acknowledgement delay means the cargo isn't released. Call the terminal or check their web portal — many can see the CBSA release message in their system even if your broker portal hasn't updated yet. FENGYE's Montreal operation runs into this weekly; the terminal has the green light but the broker's acknowledgement is still pending, and drivers sit idle waiting for paperwork that's already clear.
Don't rely on automated CAD filing workflows that depend on immediate acknowledgement to trigger the next step. If your system waits for CBSA's CAD acceptance message before auto-generating the payment instruction or updating your ERP, that workflow is now six to eight hours behind. Manual confirmation and payment may be faster until CBSA sorts out the backlog.
How Long This Usually Lasts
CBSA's track record on portal outages and processing delays over the past two years suggests these backlogs clear within seventy-two hours if the root cause is a server capacity issue or a software patch gone wrong. If it's a vendor integration problem or a database corruption issue, expect a week or more. Update nineteen on April 29 is the nineteenth communication since April 25, which means CBSA has been working the problem for four days already and hasn't resolved it. That's longer than typical.
The fact that inbound processing is only delayed one to three hours while outbound acknowledgements are six to eight hours behind points to a bottleneck in the message dispatch queue, not the intake side. That usually means the fix is server scaling or clearing a stuck batch job, which should be faster than re-engineering the EDI translation layer. But we've seen CBSA portal issues drag on for two weeks when the problem touches multiple subsystems.
Filing Strategy Until This Clears
Treat acknowledgements as non-real-time until CBSA posts an all-clear. File your ACI, your CAD, your eManifest amendments on the normal schedule, but don't wait for the automated response before moving to the next step. Verify status through the CARM Client Portal's transaction history or by calling CBSA directly if timing is tight.
If you're running Release on Minimum Documentation and counting on same-day turnaround, plan for an extra half-day of terminal dwell. RMD works when the release message arrives before the drayage appointment window closes. A six-hour acknowledgement delay turns same-day RMD into next-day pickup unless you file the ACI a full day early.
For brokerage clients who rely on us to flag CAD rejections or missing documents within an hour of filing, expect that notification to lag by most of a working day until the outbound message queue returns to normal. We're still filing on time — CBSA just isn't telling us the outcome as fast as usual.
We've been running CADs through this backlog since Friday. The five-day accounting deadline hasn't changed, and neither has the penalty structure if you miss it. Drop us a line if you want a second set of eyes on your current filings before the acknowledgement window closes.
