TL;DR: Amazon Canada’s 2026 storage and aging fee structure makes slow-moving inventory progressively more expensive. YYZ1 and YYZ4 sellers reduce fee exposure by applying a cost-based inventory decision framework: compare ongoing FBA storage cost against recovery value, and use proactive removal + local Ontario prep resubmission to reset the fee clock on recoverable inventory.
Are you watching your profits bleed away into Amazon’s monthly and long-term storage fees? As we move into early 2026, many sellers using YYZ1, YYZ4, YXU1and YYZ7 fulfillment centers are facing record-high storage costs for overstock and seasonal inventory.
At MoRo Prep, we help international sellers regain control of their margins. Based locally in St. Thomas, Ontario, our warehouse serves as your strategic “buffer zone” to bypass Amazon’s expensive storage system.
Why Your Current Storage Strategy Might Be Failing
If you keep 100% of your inventory in FBA, you are paying a premium for space that should only be used for fast-turning products. For items with a slower sales velocity, or removal orders waiting for a second life, a neutral 3rd-party partner like MoRo Prep is essential.
The MoRo Prep Advantage: Beyond the Virtual Warehouse
Unlike “virtual” platforms that just broker space, we operate from a fixed physical warehouse location in Ontario.
- Proximity Matters: Our location in St. Thomas allows for rapid receiving of removal orders from YYZ and YYC clusters.
- Operational Accuracy: We use professional scanning and tracking systems to ensure your FNSKU relabeling and inspections are handled with 100% precision.
- Fast Turnaround: We typically process and prep your inventory within 24-48 hours, allowing you to re-ship to FBA only when you need the stock.
Before You Decide: A Cost-Based Inventory Decision Framework
Before creating a removal order or moving inventory out of FBA,
the real question is not “Can I save storage fees?”,
but “What is my total execution cost versus continued FBA holding?”
At MoRo Prep, we evaluate inventory decisions based on four execution variables:
- Inventory Type: Aged inventory, seasonal overstock, or low-velocity SKUs
- Execution Path: Removal → inspection → relabeling → re-shipment or hold
- SKU Complexity: Single-SKU cartons vs mixed-SKU pallets
- Time Sensitivity: Immediate cost relief vs delayed re-entry to FBA
Estimated Decision Cost =
(Removal & Transport) + (Inspection & Relabeling) + (Holding Time)
vs.
Ongoing FBA Storage + Aging Surcharges + Loss of Flexibility
This framework helps sellers decide whether to remove, relabel,
hold, or liquidate inventory — before costs compound further.
Step-by-Step: How to Use MoRo Prep to Lower Costs
- Identify Overstock: Audit your IPI score and identify SKUs incurring high fees at YYZ1 or YYZ4.
- Create Removal Orders: Ship your inventory to our St. Thomas facility.
- Inspect & Relabel: Our team inspects the goods, relabels them if necessary, and holds them in our secure, cost-effective storage.
- Just-in-Time Replenishment: When your FBA stock runs low, we prep and ship your units back to Amazon immediately.
Stop Paying for “Dead” Space
Don’t let Amazon’s storage fees eat your 2026 Q1 profits. Whether you need returns processing, FNSKU relabeling, or a reliable prep and ship partner in Canada, we are here to help.
If inventory is now a survival decision, the next question is not whether to act,
but how to decide when to remove, hold, or liquidate inventory under cost pressure.

Understanding Amazon Canada’s 2026 Storage Fee Structure
Amazon Canada charges monthly inventory storage fees based on the cubic footage your products occupy in their fulfillment centers. The fee structure runs on a two-rate system that catches many sellers off guard: from January through September, you pay $0.87 per cubic foot per month. From October through December, that rate jumps to $2.40 per cubic foot — nearly three times higher.
Most consumer goods fall somewhere between 0.5 and 1.5 cubic feet per unit, depending on packaging dimensions and how Amazon measures your shipment. To put this in concrete terms, consider a seller holding 500 units at 1 cubic foot each. During the off-peak months of January through September, monthly storage runs $435. Once October arrives, that same inventory costs $1,200 per month to store — a 175% spike with no change in your sales velocity or product performance.
The problem is timing. Many sellers don’t see the damage until their October fee statement lands, at which point Q4 is already underway and removal logistics become rushed and expensive. Planning your inventory position in August and September gives you the window to act strategically rather than reactively.
The Remove-and-Resubmit Strategy Explained
The remove-and-resubmit approach is straightforward in concept but requires deliberate execution. When you identify Q3 inventory that has been sitting for 90 days or more and won’t realistically sell through before the Q4 fee rate kicks in, you pull it out of Amazon’s fulfillment network, hold it briefly at a third-party prep center, and resubmit it as a fresh FBA inbound shipment once Q4 demand rises and you’re confident the units will move quickly.
The math works in your favour more often than sellers expect. A removal order from Amazon costs $0.97 per standard-size unit. Shipping that unit to a prep center adds roughly $0.40 in freight. That puts your total removal cost at approximately $1.37 per unit. Compare that against two to three months of Q4 storage at $2.40 per cubic foot for a one-cubic-foot unit — you’re looking at $4.80 to $7.20 in avoidable storage fees per unit.
For mid-volume sellers running removal batches of 300 to 600 units, this strategy routinely saves $800 to $2,000 per SKU. The savings compound when you have multiple aging SKUs eligible for the same removal cycle. A prep center can receive, inspect, relabel if needed, and hold your inventory until you’re ready to create the new inbound shipment — keeping your units in clean, sellable condition without paying Amazon’s Q4 premium for the privilege of warehousing them.
Four Inventory Categories to Guide Your Decision
Not every SKU warrants removal. Before triggering any removal orders, segment your inventory into four categories and apply the appropriate action to each.
| Category | Description | Recommended Action |
|---|---|---|
| Active Performers | Sells 30 or more units per month with healthy, consistent velocity | Hold — units will turn over before Q4 fees accumulate significantly |
| Seasonal Sleepers | Low October velocity but historically peaks in November and December based on prior-year data | Hold and increase PPC spend to accelerate sell-through once demand rises |
| Stranded Aged | 120 or more days in the fulfillment center, low velocity, no identifiable seasonal demand pattern | Remove before September 30 to avoid the full Q4 rate cycle |
| Unsellable Returns | Customer returns that have failed Amazon’s condition check and cannot be resold as new | Submit for disposal or route to a prep center for liquidation processing |
Running this segmentation by mid-September gives you enough lead time to initiate removal orders, coordinate inbound scheduling with your prep center, and avoid the administrative bottleneck that hits when every seller rushes removals at the same time in late September.
Calculating Your Break-Even Point
Before pulling the trigger on any removal, run the break-even calculation for each SKU. The formula is:
Break-even (in months) = (Removal cost per unit + Prep center handling per unit + Resubmission shipping per unit) ÷ Q4 monthly storage fee per unit
Using realistic figures: Amazon removal fee of $0.97, prep center handling of $0.45, and resubmission shipping of $0.35 gives you a total out-of-pocket cost of $1.77 per unit. If your product occupies one cubic foot, your Q4 monthly storage fee is $2.40 — but on a per-unit basis, divide that by the number of units per cubic foot your shipment averages. For a product where one unit equals roughly one cubic foot, the monthly Q4 cost is $2.40. However, for denser products, the per-unit fee drops considerably, which shifts the break-even calculation.
In a worked example using $0.40 as the per-unit monthly Q4 storage cost (a denser product): $1.77 ÷ $0.40 = 4.4 months. That means if you expect the inventory to sit for four months or more through Q4, removal is the financially correct decision. If you expect to sell through in under four months, holding is cheaper.
Run this calculation for each eligible SKU by the last week of September. The sellers who treat this as an annual planning exercise — rather than a panic response — consistently come out ahead on storage costs and enter Q4 with a cleaner, more agile inventory position.
