PARS: The 72-Hour Advance Notice
Every import into Canada starts with CBSA's PARS (Pre-Arrival Review System). The broker files 72 hours before the container lands. That filing tells CBSA everything: commodity codes, shipper, value, proposed duties, compliance history. CBSA reviews it and makes an early call: release via RMD (Release on Minimum Documentation), flag for physical exam, or request additional documents.
From our dock perspective, PARS is just advance notice that something is coming. The broker is handling the paperwork and risk mitigation. Our job is simpler: know whether it'll arrive released or held, because if it's held, we don't have a dock door free, and your 48-hour dock-to-stock SLA vanishes.
CARM Replaced the B3—Here's What Changed for the Warehouse
In 2024, CBSA moved all customs declarations to CARM (Commercial Accounting Declaration system), phasing out the legacy B3 form. The filing mechanism changed, but the dock reality didn't. Importers still need duties posted or suspended, CBSA still screens for compliance, and containers still arrive flagged or clear.
What did change for us: the broker's RMD workflow moved into the CARM system, and documentation trails got cleaner (fewer paper holds on missing forms). But the one thing that didn't change is this—if CBSA wants to examine the cargo, CARM doesn't make that faster. An exam still takes 2-3 working days minimum, and we still lose dock doors.
The Exam Hold: Three Days Nobody Planned For
CBSA doesn't examine every container, but they examine enough that importers should plan for it. Physical exam happens for commodity-risk reasons: prohibited goods checking, tariff classification dispute, valuation concern, supply-chain audit. When it happens, your container sits on our dock or in a CBSA hold area while inspectors verify goods against the CAD (Commercial Accounting Declaration).
We routinely see 2-3 working days for an exam hold. Best case, Friday morning exam, released Friday afternoon. Worst case, Wednesday exam, not cleared until Friday morning, and you've burned your entire dock-to-stock buffer plus lost your cross-dock cutoff.
Here's the operational chain: you scheduled Monday shipment. Container was supposed to arrive Friday morning released, break down by Friday afternoon, pick-pack Saturday, ship Monday. CBSA exam pushed it to Friday afternoon. By Monday morning, you're already past your next-day cross-dock window (14:00 the day prior). Cargo now sits one night in holding at our in/out rate. Shipper gets pushed Tuesday. Customer feels it.
Release Types: RMD vs Full Hold vs Bonded
RMD (Release on Minimum Documentation) is the fast path. CBSA clears the cargo based on the filed CAD, duties post to your account, container moves within hours of arrival. That's your 48-hour dock-to-stock baseline.
Full examination, as above, is a 2-3 day hold. Once cleared, you still move, but the timeline is already compressed.
The third scenario is bonded in-transit, pending final duty determination or CBSA review. That's where FENGYE LOGISTICS' in-bond cargo handling becomes the buffer zone. We're CBSA-authorized sufferance warehouse. Duties stay suspended. You pay only our storage rate (lower than demurrage, no VAT, no duty front-load). Import takes a month to resolve duty classification or appeal a tariff ruling. Cargo sits in our bonded area, not bleeding detention charges at the port.
Port Drayage and Container Free Time
Before your container even reaches our dock, it's burning Port of Montreal free-time windows. Drayage must happen within that window or demurrage compounds. If CBSA exam ate three days, and you didn't plan a buffer, you're paying both port detention and drayage detention to your trucking company.
This is the hidden cost most importers don't see. They think exam = delay. They don't calculate exam + missed free-time + drayage overage + storage spike. The math gets ugly fast.
Dock-to-Stock SLA and Cross-Dock Cutoffs
Once released and delivered to FENGYE, our standard dock-to-stock is 48 hours: receive, QC, system entry, ready to pick. That clock assumes released cargo with no holds.
Cross-dock is faster but has teeth. Cutoff is 14:00 (2 PM Montreal time) for next-day outbound. Arrive before 14:00, and we sort, restack, and ship next day. Arrive at 14:01, and the pallet sits overnight in holding at our in/out rate. One extra night of storage, one extra day of transit time, one extra day your customer waits.
Exam delays routinely push arrival past that cutoff. We see it every week. And it's not the warehouse's delay—it's the exam hold's delay. But the customer sees your shipment as late.
Bonded vs Released: Fee Structure and Cash Flow
Released cargo: duties paid or posted to account, moves to regular storage, standard handling and racking rates apply.
In-bond cargo: duties suspended pending resolution, bonded storage rate (lower, no VAT prepayment), full CBSA compliance reporting on our end. The advantage: you're not bleeding demurrage while duty classification is under dispute. The trade-off: bonded storage is typically gated—certain warehouses only, CBSA-authorized facilities. We're CBSA-licensed, so we can hold it. Many 3PLs can't.
Importers often panic when CBSA says "hold pending exam." In reality, if duties are suspended, we've got bonded space, and you're not bleeding money. It's not ideal, but it's not the crisis they think it is.
CARM Phase 2 and What's Changing Next
CBSA's CARM system rolled out in phases. Phase 2 brought RMD into CARM and tightened electronic filing standards. This sounds like bureaucratic tick-boxing, but it matters on the dock: fewer manual holds for documentation errors, faster release decisions when docs are clean, harder hits when docs are sloppy.
Importers who invested in clean CAD prep now see tighter cycle times. Importers who're still filing half-measured declarations hit CBSA review delays more often. The playing field got meaner, not kinder.

Real Planning Beats Reactive Scramble
The Canada customs clearance process is three gates: PARS 72 hours out, CBSA exam screening (yes or no, usually 2-3 day hold if yes), release and payment sequencing. Every gate can add 1-3 days. Plan for downside. Build a 3-day buffer into your inbound plan, not because it's broken but because it's normal.
We handle exam holds weekly. We push cross-dock cutoffs. We hold cargo in-bond without premium. What we can't do is absorb importers who don't plan timelines and then treat the warehouse like we caused the delay.
The process is rule-bound and mostly automated now. But automation doesn't mean frictionless. Knowing where the friction lives—dock doors, exam holds, port free-time, bonded vs released storage, drayage windows, cross-dock cutoffs—is the difference between a clean 48-hour inbound and a 72-hour scramble.
This is the clearance cycle we run every week at FENGYE LOGISTICS. If your current logistics partner is treating exam holds like a surprise instead of a routine downside to plan around, talk to a broker who works dock-close, and pair them with a warehouse that doesn't treat delays like aberrations.
