Read This Before Your Next Container Ships

Cargo insurance in Canada is easy to set up once and then forget. You import or export goods every month, each shipment is insured, and the policy has never let you down. Then a port fire, a storm, or a warehouse collapse hits several of your shipments at once, and you learn that the policy limit applies to everything sitting in one place, not to each shipment on its own.

The problem is that many businesses check coverage shipment by shipment, while losses can happen location by location. The goal here is to help you look at your cargo coverage like an underwriter, not like a busy shipper, so you can spot gaps before a single event exposes them.

This focuses on Canadian businesses that move goods by ocean or air, as well as the warehouses in between. Policy terms vary by insurer, and the wording in your own policy is what counts. This matters even more heading into year-end, when many businesses ship larger orders, hold more stock, and see their goods sit longer at ports and warehouses.

What Is Cargo Insurance in Canada, and How Do Limits Work?

Cargo insurance protects goods while they travel, and often while they are stored along the way. In plain terms, it may help you recover the cost of goods that are:

• Damaged, lost, or stolen in transit by sea, air, rail, or road
• Lost in events like fire, storms, or a vessel accident
• Damaged while waiting at a port, terminal, or warehouse, depending on the policy

It is different from relying on the carrier. A shipping line or trucking company is usually responsible for your goods only up to limits set in the bill of lading or by law, which can be far below what your cargo is worth. Insurers note that many cargo owners wrongly rely on inland policies and bills of lading, and only find the gaps when a claim arises.

Most business cargo policies set two key limits:

• A limit for any one shipment, such as one container or one air consignment
• A limit for any one location or conveyance, such as one vessel, one port, or one warehouse

That second limit is where the hidden problem sits.

What Is Cargo Accumulation Risk, and Why Is It Growing?

Accumulation risk happens when several insured shipments are exposed to the same event at the same time. Each shipment may be insured properly on its own, but together their value can be far above your per-location limit.

That is becoming more common because:

• Bigger ships carry more containers, so more of your goods can end up on one vessel
• Rerouting and port congestion can send several shipments to the same port at once
• Higher prices and inflation raise the value of goods before they even leave port
• Businesses facing tariff uncertainty are importing larger shipments and holding goods in storage longer

This all sounds technical, but here are limits that rarely show up until a claim:

• The per-location limit may be much lower than the total value of goods sitting in one warehouse during peak season
• Storage at a port or third-party warehouse may be covered only for a set number of days
• Delay alone is usually not covered, even if goods arrive too late to sell

Red Flags Hidden in Policy Conditions

The trickiest parts of cargo insurance in Canada often sit in the conditions, not the headline limit. Watch for:

• The accumulation clause: It sets how much the insurer will pay if more than one shipment is caught in the same event, and it can require you to report accumulations quickly.
• The basis of valuation: If your insured value covers only the invoice price, freight, duties, and other landed costs may be left out. A recent Lockton Canada report notes that property, cargo, and business interruption values may no longer reflect real replacement costs once duties are factored in.
• Warehouse time limits: Coverage at a warehouse may end after a set number of days unless you extend it.
• Packing and theft conditions: Poor packing, unsecured containers, or a missing security step can reduce or void a claim.

Timing is another quiet trap. Many policies require you to tell the insurer when an accumulation is likely, such as several high-value shipments sitting in one port. Telling them after a loss may be too late.

How Does a Cargo Accumulation Claim Work?

Here is how the numbers can work. The figures are illustrative, and every policy calculates claims a little differently:

• An importer has three containers, each worth $400,000, waiting at the same port during a peak-season backlog
• Each container is within the $500,000 per-shipment limit
• The policy has a $750,000 limit for any one location
• A port fire destroys all three, causing a $1,200,000 loss
• After a $5,000 deductible, the policy pays its $750,000 location limit
• The importer absorbs the remaining $450,000

No single shipment was underinsured. The shortfall came only because the goods ended up in the same place at the same time.

Smart Ways to Close the Gap Before Your Next Shipment

Cargo gaps are easiest to fix before goods are on the water, not after a loss. Before peak season, you can:

• Add up the value of goods that could sit in one port, vessel, or warehouse at the same time
• Compare that total with your per-location limit
• Check whether your insured value includes freight, duties, and other landed costs

Good questions for your broker include:

• What is my limit for any one location or vessel, and is it high enough for peak season?
• How long are goods covered while stored at a port or warehouse?
• Would a stock throughput policy, which covers goods in transit and in storage under one policy, fit my business better?
