The Outage That Keeps Running
CBSA's EDI and eManifest portal message backlog entered its second week on May 1, with residual delays on both inbound and outbound transmissions still affecting electronic filing. The Systems Outage Contingency Plan remains in effect, meaning paper entries are accepted, manual workarounds are live, and brokers are making real-time calls on whether to wait for EDI acknowledgment or pivot to paper CADs and cargo control documents.
This isn't a brief service window. The original outage began April 25 at 08:00 ET. Update 32, issued this week, confirms the system is functioning but acknowledgment latency is unpredictable. If you're an importer waiting on release confirmation or a broker trying to time a payment cycle, the gap between transmission and acknowledgment can stretch hours or drift into the next business day. That timing gap changes how we manage RPP bond exposure, when we advise paying duties upfront, and whether a Friday afternoon filing is viable or a Monday morning problem.
What Paper Filing Actually Looks Like in 2026
The SOCP allows paper Commercial Accounting Declarations and paper cargo control amendments. In practice, paper CADs mean preparing PDF or printed forms with all the data fields that would normally transmit via EDI: importer BN15, vendor invoice detail, HS classification at the tariff item level, CUSMA or CETA preference claims with certificate references, valuation basis, and any SIMA or OGD flags.
Paper is slower, not because the form is harder to fill out, but because CBSA officers process paper sequentially at the port or inland office. Electronic CADs route automatically to the correct workstream based on targeting rules. Paper CADs sit in a queue. If your shipment arrives at a high-volume sufferance warehouse in Montreal and the electronic feed is lagging, the paper route may be faster. If your cargo hits a smaller regional office with light staffing, paper can add a full day.
We're filing paper selectively. High-value shipments with tight RPP bond headroom go electronic and we wait for acknowledgment, because the CARM Client Portal settlement cycle depends on that electronic trail. Low-duty shipments with same-day delivery commitments go paper if EDI acknowledgment is running past two hours. The call changes hourly based on what we're seeing in the portal queue.
The Downstream Mess: Drayage, Dwell, and Detention
Message delays don't just slow down release paperwork. They cascade into drayage windows, container free time, and warehouse receiving schedules. A shipment that normally clears within four hours of ACI transmission and proceeds to same-day pickup now sits an extra six to twelve hours waiting for inbound acknowledgment. That delay burns part of the container free-time window at the terminal, pushes the drayage appointment past the carrier's cutoff, or forces the container into overnight storage at the port.
For importers using release prior to payment with tight bond utilization, the acknowledgment delay also affects when the CAD posts to the CARM ledger and when the RPP bond balance updates. If you file a CAD Monday morning and acknowledgment doesn't arrive until Tuesday afternoon, that duty liability sits in limbo. The K84 monthly statement won't reflect it until the posting cycle closes, but your available bond room is effectively reduced the moment you transmit. We've had two clients this week ask whether they should pre-pay duties to avoid bond overruns, purely because acknowledgment timing is unclear.
What We're Watching
CBSA's updates reference "residual delays" and "currently functioning well," which tells us the acute failure is resolved but throughput is not back to normal. Inbound processing is the bottleneck. Outbound acknowledgments to brokers and carriers are lagging behind. That split means cargo can be released on the CBSA side but the electronic confirmation to the carrier's eManifest system, or to the broker's internal workflow, arrives late. The cargo physically moves, the paperwork trails by hours.
We're also tracking whether CBSA will formally declare the SOCP closed or let it expire quietly. The contingency plan includes temporary acceptance of amended cargo control documents submitted after the regulatory deadline, expedited paper processing at certain ports, and relaxed timelines for penalty assessment under AMPS. If the plan stays open into the second week of May, it's a signal that CBSA doesn't trust the system's recovery yet.
What Importers Should Do Right Now
If you're waiting on release confirmation for a shipment filed in the past 48 hours, check the CARM Client Portal directly rather than relying on email notifications. Outbound messages to brokers are delayed, but the portal's CAD status page updates faster. If your CAD shows "Released" in the portal but your broker hasn't sent confirmation yet, the delay is on the acknowledgment transmission, not the actual clearance decision.
For shipments arriving this week, confirm with your customs broker whether they're filing electronic or paper. If your cargo is time-sensitive and your broker is waiting on EDI acknowledgment past two hours, ask them to pivot to paper. The SOCP remains in effect, paper is accepted, and the marginal cost of a paper filing is lower than a day of container detention or a missed delivery window.
If you're managing RPP bond utilization, assume a 24-hour lag between CAD transmission and ledger posting until CBSA confirms full electronic throughput is restored. That lag doesn't change your duty liability, but it does affect whether you have room under your bond ceiling for the next shipment. We're advising clients with bond utilization above 80% to either pre-pay duties or delay non-urgent filings until acknowledgment speed normalizes.
Our Take
Most CBSA service notices are noise. This one isn't. A two-week EDI backlog with the SOCP still active means electronic filing is unreliable enough that the agency is keeping the manual escape hatch open. That's not a precaution, it's a working assumption that message delays will continue.
We're filing both electronic and paper depending on the shipment, tracking acknowledgment times in real time, and advising clients on bond and payment timing case by case. If your release timelines have felt unpredictable this week, this is why. The system works, but the speed is off, and speed is half the value of electronic filing.
If your shipments are stacking up at the port or your bond math looks wrong because CADs aren't posting on schedule, get in touch. We're running through this every day right now and the workaround depends on your specific cargo and clearance pattern.
