Canada customs clearance process step by step: what happens at the dock

The broker submits before the truck shows up

Your customs broker files the Pre-Arrival Review System (PARS) submission before your container hits the Port of Montreal or a drayage drop-point. This is not the declaration itself — it's the advance notice. The broker pulls shipper data, enters the cargo description, and flags the shipment in CBSA's system so that when the truck rolls up, there's already a record waiting.

PARS doesn't clear your goods. It just tells CBSA, "This shipment is coming." The actual clearance decision happens after the truck arrives and the broker files the Commercial Accounting Declaration (CAD). That's the post-CARM form that replaced the old B3 back in 2024. The CAD is where tariff classification, duty values, and origin claims live.

The gap between PARS and the CAD landing matters for your dock schedule. A typical PARS-to-dock window at Port of Montreal is 24 to 48 hours, but drayage delays, vessel schedules, and rail positioning can stretch that. We plan for a 48-hour buffer on inbound because broker submission timing is rarely predictable from the warehouse side.

The shipment arrives; CBSA decides right away or holds it

Once the truck pulls into our dock at FENGYE LOGISTICS or arrives at the port terminal, the drayage driver presents the bill of lading and any release documentation to the terminal operator or our receiving team. If CBSA has already processed the CAD and cleared the shipment, the terminal or warehouse releases it immediately under what's called "Release on Minimum Documentation" (RMD). This is the fast path.

More often than not, especially on food, chemicals, textiles, or anything flagged by trade agreements like CUSMA or CETA, CBSA holds the shipment for examination. An exam hold doesn't mean the goods are seized — it means a CBSA officer wants to physically inspect the container or a sample of the cargo to verify that the classification, origin claim, or tariff treatment matches the CAD the broker filed.

That hold adds 2 to 5 working days to your dock-to-stock timeline. We've seen holds stretch to 8 to 10 days in Q4 when Port of Montreal examination capacity gets thin and dwell times back up. The broker can sometimes request a "release under suspension of duties" while the exam happens, but CBSA doesn't grant that automatically — it depends on the commodity, the importer's compliance history, and whether duties are in dispute.

Examination, duty assessment, and the release decision

During the exam, a CBSA officer physically opens the container or samples pallets, cross-checks the goods against the CAD description, and verifies origin documentation if the shipment claims CUSMA or CETA treatment. If the officer finds discrepancies — say, the shipper misclassified the product, or the country of origin doesn't match the invoice — the broker gets notified and may have to file an amended CAD, supply supplemental origin certificates, or accept higher duty rates.

This is where the broker's work directly impacts warehouse receivables. A rejected origin claim on textiles can mean the difference between 0% CUSMA duty and a 15-22% base tariff rate applied retroactively. The goods don't move from our dock until that dispute is resolved and the broker files the corrected CAD with CBSA.

Once the exam clears or the amended CAD is approved, CBSA issues a release. The broker gets the release, submits it to the terminal or warehouse, and the goods are now cleared to pick-pack, cross-dock, or store in bond. From the dock side, that release looks like an RMD code or a release memo that the drayage driver or receiving clerk needs to see before the pallet leaves the terminal.

In-bond storage if duties are deferred

Not every import is released for immediate consumption. If the importer chooses to defer duties or store the goods for later release or re-export, the shipment enters a bonded warehouse or sufferance warehouse instead of going into general warehouse storage.

FENGYE LOGISTICS operates as a CBSA-authorized sufferance warehouse, which means we can store goods under bond while duties and taxes are suspended. This is common for high-value electronics, machinery, or goods destined for transshipment. The broker files a different kind of entry — an in-bond entry rather than a domestic release — and CBSA allows the goods to sit in our facility without paying duty until the importer decides to release them for consumption or export them onward.

In-bond storage carries its own compliance layer. We run daily reconciliation of bonded inventory, track expiration dates on the in-bond authority (which CBSA specifies per entry), and prepare release documentation for the broker when the importer finally decides to take the goods out of bond. If an in-bond entry expires and the importer hasn't released or re-exported the goods, CBSA can seize them or assess penalties.

After release: dock-to-stock timing and accessorial fees

Once CBSA releases the shipment, the clock starts for warehouse operations. Our published dock-to-stock SLA is 48 hours from the time the release memo hits our dock. That window covers receiving, de-consolidation if needed, quality check, label application, and putaway into racking or floor storage.

Most of that 48 hours is actually logistics setup — waiting for drayage to arrive, negotiating dock-door windows with the Port of Montreal terminal, or handling cross-dock consolidation if the importer is pooling multiple shipments. The actual receiving-to-storage cycle is usually 6 to 12 hours once the truck is at the dock door.

Accessorial charges start accumulating if we're holding goods beyond the agreed free-storage window. Our in/out rate runs around CAD 12 to 15 per skid per day for sufferance warehouse storage; unbonded general storage sits higher, closer to CAD 18 to 25 per pallet per day depending on racking density and the shipper's handling specs. If a release is delayed and the importer doesn't move the goods, those charges compound fast. A 40HC container holding 20 pallets for an extra week can cost CAD 1,200 to 1,800 just in storage.

Common delays and where they actually happen

The Canadian customs clearance process has several friction points that ops teams encounter repeatedly. Understanding them helps you set realistic inbound schedules and manage shipper expectations.

Broker submission timing is the first one. Shippers don't always send complete shipper declarations or origin certificates before the vessel sails. The broker files PARS with incomplete data, then amends it when the full documents arrive. That amendment can trigger a re-review by CBSA if the tariff classification or origin claim changed. We've seen CAD filings delayed by 3 to 5 days because the shipper's origin invoice was missing or contained unit prices that didn't match the declared value.

Examination holds are the second. CBSA conducts physical exams based on risk profiling and commodity category. Certain goods — food products, chemicals, footwear, and anything subject to antidumping or safeguard investigations under CITT jurisdiction — get examined at much higher rates. A random exam can be resolved in 24 hours. A targeted exam on a trade-sensitive product can hold a container for a week or more.

Documentation disputes are the third. Origin claims fail because the shipper's invoice says "Made in Vietnam" but the origin certificate says "Product of Thailand." Tariff classification gets challenged because CBSA's lab analysis shows the product is HS code 3915 (plastics waste) rather than 3916 (plastic monofilament), which flips the duty rate by 8 percentage points. These disputes require the broker to gather supporting evidence, file supplemental letters, or request a CBSA ruling memo. That process takes 10 to 20 working days.

Drayage and port logistics are the fourth. Even if CBSA clears your shipment in 24 hours, the Port of Montreal or the rail ramp (CN/CP) may not have a dock door available. Container free time at the Port of Montreal runs 5 days; after that, demurrage charges start at CAD 35 per TEU per day. If your drayage is delayed and you're burning free time waiting for a dock window, that's a logistics cost that often gets buried in the clearance timeline.

What your ops team needs to track

When you're managing inbound from a warehouse standpoint, you need visibility into five things: PARS submission date, CAD filing date, exam hold status, release date, and actual dock arrival. The gaps between those dates tell you whether delays are happening in customs processing or in physical logistics.

Most brokers provide a status email or portal update when they file the CAD and when CBSA issues the release. That release memo is your legal trigger to accept the shipment into the warehouse. Without it, goods sitting on a truck at the dock door are still under customs control, and you cannot move them into your facility or onto the importer's premises.

If a release is delayed past the broker's estimated clearance window, call the broker and ask for the delay reason. Is CBSA conducting an exam, waiting for documentation, or disputing the tariff classification? Each scenario has a different timeline and a different set of next steps. A documentation gap might be resolved in 24 hours if the shipper responds fast. A trade-investigation exam can add 15+ days.

For warehousing and distribution operations, knowing the difference between a 48-hour clearance and a 10-day hold is the difference between running a smooth inbound schedule and pushing outbound shipments back. Build that buffer into your SLAs, and push back on shippers who don't provide complete documentation upfront.

The compliance side: RPP bonds and duty payment

Once goods are released, the importer's duties and taxes are due. Most importers use an RPP (Importer/Exporter Account) with CBSA and have a duty bond in place. The broker calculates the duties based on the tariff classification, value declared on the CAD, and any preferential agreements (CUSMA, CETA) that apply. That duty amount gets assessed against the importer's account; the importer pays CBSA directly or the goods stay in bond until payment clears.

If the importer disputes the duty assessment — says the tariff classification is wrong or the CUSMA/CETA claim was wrongly rejected — that's a separate administrative process. The broker can request a CITT (Canadian International Merchandise Trade Tribunal) ruling on classification or a CBSA ruling memo. Those requests can delay the final duty determination, but they don't stop the warehouse from storing the goods or releasing them if the importer pays the duty under protest.

Compliance failures at this stage are costly. A broker missing a CETA certificate of origin deadline, misclassifying a product, or filing a CAD with incorrect duty values can trigger a customs assessment that hits months later. We see importers who have to remit additional duties, plus interest and penalties, because the broker's original classification was loose. That's a conversation to have with your broker upfront, especially if your import volume is significant.

Q4 and peak season realities

The Canadian customs clearance process doesn't change in Q4, but the timeline stretches. Port of Montreal dwell times extend, CBSA examination capacity tightens, and brokers are juggling higher volume. We routinely see dock-to-stock SLAs slip from 48 hours to 5 to 7 days in November and December, not because the clearance itself is slower, but because drayage windows and dock availability are constrained.

Plan for longer lead times on inbound during Q4. Ask your broker to prioritize PARS filing and CAD submission. And if you're using warehouse storage as a buffer, confirm free-storage windows upfront so surprise demurrage charges don't hit your freight bill.

The Canadian customs clearance process is repeatable once you know the sequence. PARS comes first, CAD filing happens next, CBSA decides within 24 to 48 hours, and release follows. Delays almost always trace back to documentation gaps, exam holds, or logistics bottlenecks — not the clearance system itself. Build that understanding into your planning, and your inbound will move predictably.
