What Changed When Port Congestion Eased
Supply chain optimization in Canada looked one way in 2019 and something else entirely by 2024. Pre-pandemic, the primary constraint was obvious: container dwell at the Port of Montreal. Importers optimized for that reality. Consolidate shipments, accept 5–7 day port residence, stack containers to fill a truck. The math was clear — one large shipment cost less per unit than four small ones, and port time was the cost of doing bulk consolidation.
Port congestion eased faster than most importers expected. Port of Montreal container flow normalized by mid-2023. Berth slots opened up. Terminal handling no longer required paying for priority service to get space. Importers thought they'd won the optimization game back.
They hadn't. The constraint didn't disappear; it moved downstream. A container that cleared the Port by Day 3 now waits 24–48 hours for CBSA customs clearance under the new Commercial Accounting Declaration (CAD) filing process. Once it clears, it sits waiting for a drayage window. By the time it reaches the warehouse, the savings from pre-pandemic bulk consolidation have evaporated in carrying costs and working capital drag. Importers are now optimizing around a different sequence entirely.
Customs Processing Is the New Bottleneck
Before CARM, customs clearance was a known pain but not the primary constraint. The CBSA broker filing was asynchronous with vessel arrival. Goods landed, got examined if flagged, released on average 24–36 hours post-landing if routine. Ports were the budget-killer. Customs was background noise.
CARM centralized customs filing under a Pre-Arrival Review System (PARS) submission 24 hours before vessel arrival. On paper, this is faster. CBSA now processes CADs in a more predictable intake pattern, releasing routine goods within 24–48 hours of landing. In practice, the timing is now the critical path for importers, and it's unpredictable in ways port scheduling was not.
A shipment lands Thursday afternoon. Broker files the CAD Thursday evening. Routine clearance targets Friday afternoon. But if CBSA flags the shipment for exam — because the journal doesn't match, or HS classification is queried, or the origin requires verification — release slips to Saturday or Monday. Exams at Port of Montreal happen in batches, often Monday morning, with release following. By then, drayage dispatch windows for that week have already closed. The importer's goods sit in a Port terminal for another 48–72 hours, waiting for the next drayage window.
This is operationally invisible to most importers. They see it as "customs delays." What's actually happening is that customs processing time and drayage window availability have become a coupled constraint. You can't optimize one without understanding the other. At FENGYE LOGISTICS, we coordinate customs release sequencing directly with our partner carriers' dispatch windows. If we know drayage pickup is Tuesday 06:00–08:00 EDT, we time putaway and dock staging to hit that window. Goods that miss it stay bonded at our facility, holding in-bond, until the next window opens.
Drayage: Availability Is Worth More Than Rate Discounts
Drayage costs remain 25–40% higher than 2019 baseline. Driver availability, not rate, is now the primary optimization variable. Transport Canada hours-of-service regulations cap driver on-duty time at 13 hours per day, which directly constrains how many pickup and dropoff cycles a carrier can complete during peak season.
What this means: drayage windows at Port of Montreal are fixed. Gate hours are 24/7, but dispatch windows cluster around standard trucking shifts. A carrier offers Tuesday 06:00–08:00 EDT and Thursday 14:00–16:00 EDT pickup. That's the availability. An importer can no longer negotiate "I'll pay 10% extra for flexible timing." Flexible timing doesn't exist. They either hit the window or wait five days for the next one.
The behavioral shift has been dramatic. Pre-pandemic, importers negotiated rate. "We move 50 containers a month, can you do CAD 2,400 per unit?" Now they negotiate window certainty. "Do you guarantee Tuesday 06:00 pickup in Q4?" Rate takes a back seat. A carrier that guarantees 48-hour window availability at CAD 2,700 per unit books harder than one offering CAD 2,500 with loose timing.
This has reshaped how FENGYE runs dock operations. We build inbound schedules around drayage window certainty, not around "when goods clear customs." We assume customs will clear by Friday. We stage goods Thursday night in anticipation of Friday morning dock doors. If clearance slips to Monday, goods go to cross-dock racking or in-bond holding, releasing dock space for the next shipment. Without that buffer, we'd have dock congestion every week during Q4.
The Importer Response: Smaller, More Frequent Shipments
Pre-pandemic consolidation logic broke. A 40-foot container that takes 7 days to clear (2 days Port, 3 days customs/exam, 2 days drayage delay) ties up working capital for a week on a single SKU. Inventory sits at FENGYE Warehouse or port dock instead of moving to retail distribution. The per-unit savings from consolidation evaporate once carrying cost is factored in.
Importers with tight inventory targets — 5–7 day retail turns instead of 30-day safety stock — now split shipments. Two 20-foot containers on a weekly rotation instead of one 40-foot every two weeks. First container clears and reaches warehousing and distribution services within 48 hours of release. Second lands mid-week. Inventory moves faster. The per-unit cost of handling and drayage goes up slightly, but inventory turn and working-capital release offset it.
This is especially true for importers operating on just-in-time models or maintaining in-bond cargo handling as a bridge between landing and retail. They're not carrying 30-day inventory anymore. They want goods flowing in, cleared, packed, and shipped within 10 days. Smaller, frequent shipments fit that model. Consolidation doesn't.
Rail Still Cheaper, But Dwell Is Unpredictable
Rail remains 30–50% cheaper than truck for coast-to-coast moves. CN and CP rates are published and hard to beat on a per-unit basis. But dwell is the catch that makes rail unworkable for many importers now.
CN rail free time policy is officially 5 days at intermodal yards in the 401 corridor (Lachine, Dorval). Peak season dwell runs 8–12 days, and importers absorb the overage charges. For an importer doing 5–7 day inventory turns, 12-day rail dwell is unacceptable. They can't afford to tie up goods in a CN yard for that long while capital should be turning at retail.
This is where bonded warehouse positioning matters. Goods can land at Port of Montreal by rail, get transferred to a CBSA-authorized bonded facility within 24 hours, and held there in-bond while customs processes. The goods are under CBSA seal, fully tracked, and available for release sequencing. It costs more than terminal dwell, but it keeps inventory in a controlled state. Temperature-monitored if reefer. CITRA-registered if regulated. Dual-handling beats 12-day rail yard limbo for importers on tight turns.

Optimization Is Sequence, Not Cost
The post-pandemic lesson is structural, not tactical. Optimization isn't about finding savings in one link of the supply chain. Each link — port, customs, drayage, warehouse — has its own constraint. Optimizing one while ignoring the others leaves wasted capacity downstream.
An importer who pays for priority Port of Montreal terminal handling, cutting dwell from 3 days to 1, but then waits 3 days for drayage, gains nothing. An importer who accepts 5-day drayage dwell but has no warehouse buffer space to hold released goods gets dock congestion and ties up dock doors. The wins come from aligning all four: vessel schedule, customs release window, drayage slot, and warehouse putaway cycle as a single sequence.
This is harder to measure in spreadsheets than "cost per container." But it's what actually moves goods reliably. We see it on our dock every week. Importers optimizing post-pandemic aren't chasing the 10% savings pre-pandemic consolidation delivered. They're chasing predictability and inventory turn. That's the supply chain optimization that matters now.
