E-commerce warehouse Canada: small-business fulfillment dock needs

Dock Doors Drive Everything

Most small e-commerce operations run on 1 to 3 dedicated dock doors. That's realistic for a 15,000–25,000 sq ft fulfillment space holding 400–600 pallets. In summer, you move a container every 3–4 days. In October, it's every 18 hours, and you're negotiating drayage free time with carriers while your ops manager watches detention charges climb.

Container free time at Port of Montreal is typically five days for import FCL; after that, detention charges apply hourly. Your drayage window—the time a trucker has to pick up or deliver within—usually sits at 24–48 hours depending on the carrier contract. Miss that window, and your next appointment is often two days later. That's real latency for a small seller shipping SKUs that move in days, not weeks.

The real constraint isn't warehouse floor space. It's the dock door and the schedule behind it. Warehousing and distribution operations that work are built backward from dock doors, not forward from floor space.

Seasonal Volume Swings Require Real Planning

Statistics Canada data shows Q4 e-commerce volume typically runs 2.5–3.2× baseline monthly volume. For a small fulfillment operation that's 800–1,200 units per day in summer, expect 2,500–3,500 per day starting mid-October. That inbound surge hits dock doors, not warehouse capacity. Your warehouse needs to absorb that inflow, which means confirmed dock slots reserved in advance (not ad-hoc requests), temporary cross-dock staging if racking is full, a contingency dock or an agreement to rent adjacent space, and drayage coordination pre-arranged. Don't call the carrier on October 20th asking for urgent pickups. Small businesses often skip this planning step and then blame the warehouse for slow putaway. The warehouse can't put away what didn't dock on time.

SKU Proliferation Kills Pick Efficiency

E-commerce inventory is the opposite of food service or apparel. You're holding 500–2,000 SKUs, but each one turns over slowly—maybe once every 2–4 weeks. That density (high SKU count, low case velocity per SKU) breaks racking designs that work for commodity warehouses.

A standard GMA pallet is 40" × 48", holds 800–1,200 lbs depending on product. Racking beam height is typically 90" (first tier) × 84" (tiers above) to hit 3–4 tiers per section while keeping aisles wide enough for picking carts. But when your SKUs are small (beauty, electronics, books), you're row-racking or bin-shelving more than pallet-racking, which means higher labor per pick and tighter aisle management. Putaway cycle time matters. Most 3PLs target 24–48 hours from dock receipt to racked-and-scanned. Faster than that, and you're adding labor. Slower, and your incoming flow backs up. Your warehouse contract should name that SLA explicitly, not as an aspirational footnote.

Cross-Border Clears Aren't Instant

If your suppliers are in the US or EU, Canadian Customs is your checkout counter. CBSA's Pre-Arrival Review System (PARS) gates how fast a broker can release your freight—it's not the warehouse's job to clear, but the clearance timeline directly affects when the warehouse can receive and push inbound to dock. A typical customs examination, if flagged, delays release by 2–5 working days. If your delivery promise to a US customer is 7 days total, and customs eats 3 of those on the import side, you've burned half your buffer on something the warehouse can't control. What matters is coordination: your warehouse partner should confirm with the broker that PARS is filed before the container docks, not after.

What to Ask Before Signing

1. Dock door count and utilization. Not "we can fit 4 trucks a day if everything aligns," but "we have 3 dedicated inbound doors, 2 outbound, and you get X confirmed slots per week."

2. Dock-to-stock timeline. Actual SLA, not aspirational. 48 hours is reasonable; 72 is standard; under 24 is premium.

3. Cross-dock capability. Can they stage fast-moving inventory and ship same-day or next-day without racking it? That's the single biggest speed lever for e-commerce.

4. Drayage coordination. Do they manage carrier pickups, or do you? Who pays detention if the dock isn't ready?

5. Temperature control. If you ship reefer goods (frozen, temperature-sensitive), confirm equipment and SLA separately.

The warehouse should give you those answers as numbers, not reassurances.

Small Doesn't Mean Improvised

E-commerce fulfillment works when three pieces move together: dock throughput, SKU picking, and carrier scheduling. Small operations often under-invest in the first and second, then blame the third when delivery windows slip. If your current partner can't name dock door SLAs or SKU velocity targets, it's not a partnership—it's a space rental.
