Quick Answer: For parked, long-term storage in Ontario, a 20ft shipping container beats an enclosed cargo trailer on space, security, and upkeep: 33.2 cubic metres at ground level, no tires to flat-spot, no trailer paperwork to think about. Keep the trailer if you genuinely haul. Van Blanc delivers sea cans across Ontario in 1-3 days.
A third cousin turns up at every farm auction: the retired cube van box sold as a cheap shed, which earns its own honest comparison.

The Buyer This Page Is Written For
Every week someone lands on Kijiji or AutoTrader looking at 7×14 and 7×16 enclosed cargo trailers, and a good share of them have no plan to tow anything anywhere. The trailer is going to get parked behind the shop, loaded with tools, off-season equipment, or business overflow, and left there. It moves twice a year, maybe never.
If that is you, this comparison exists because you are about to pay for a road vehicle to do a stationary job. A trailer is a superb tool for hauling. As a parked storage box, it competes directly with a 20ft shipping container, and the container wins that specific contest on almost every line: interior volume, floor strength, security, weather, lifespan, and what it asks of you over ten years. We sell sea cans, so weigh our bias accordingly, but the evidence below is checkable, and we will tell you plainly when the trailer is the right buy.
One boundary first. This page is about consumer enclosed cargo trailers, the tandem-axle boxes contractors tow behind a pickup. If you were pricing 53ft storage vans from a fleet yard, that is a different product with different math, and we cover it separately in our storage trailer comparison.
What Does an Enclosed Trailer Cost You While It Sits?
A parked trailer is a machine slowly losing an argument with physics. The storage-prep industry itself documents the pattern: tires develop flat spots and sidewall cracks under a stationary load, wheel bearings weep and pit, brake components seize, and roof and door seals dry, shrink, and open gaps that let water reach the plywood. Trailer service shops publish long-term storage checklists precisely because an unmaintained parked trailer deteriorates faster than one being used: blocking the axles, rotating the tires, repacking bearings, resealing the roof. That is real annual labour, or a real repair bill deferred.
A shipping container asks for none of it. There are no tires, bearings, brakes, lights, or wiring. The box is 14-gauge corten steel on a frame designed to carry over 28,000 kg of cargo across an ocean, and its four corner posts sit on blocking or gravel with nothing to seize. The one maintenance habit worth having is a rag wipe of the door gaskets and a hinge oiling once a year, and checking your site prep has not settled. Buyers tell us a decade in that the bin looks like the day it landed.
The Ten-Year Question
Price both boxes, then add ten years of ownership to each. The trailer carries tires, bearings, seals, and brake work whether it rolls or not. The container carries a hinge oiling. For a box that never leaves the yard, you are paying the trailer’s rolling costs for a capability you are not using.
What Paperwork Follows a Trailer That a Container Never Asks For?
In Ontario a trailer is a vehicle. It gets registered and plated, and Ontario’s own guidance sets out how trailers are treated for registration and road use. Insurance depends on how the trailer is used: towed on public roads, it is generally covered under the towing vehicle’s policy, and brokers recommend standalone or contents coverage in several situations, including trailers parked long-term on a property. None of that is exotic, but it is a file you carry for as long as you own the thing, and it is worth a conversation with your own broker either way.
A shipping container is not a vehicle. It is cargo equipment built to the international ISO 668 standard, identified under the container numbering system, and once it is set on your property it is simply a steel structure you own. No plate. No renewal. Nothing to declare when it does not move, because it was never registered to move itself in the first place. For a business parking capital in “storage”, that difference alone tidies up a surprising amount of admin over a decade.
How Much More Does a Sea Can Actually Hold?
A 20ft container holds roughly half again more than the largest common enclosed trailer, on a stronger floor, with more than a foot of extra standing height. The numbers:
| Spec | 7×16 enclosed trailer (typical) | 20ft shipping container |
|---|---|---|
| Interior volume | about 20-21 m³ (roughly 730 cu ft) | 33.2 m³ (1,172 cu ft) |
| Interior height | about 1.98 m (6’6″) | 2.39 m (7’10”) |
| Floor | 19 mm (3/4″) plywood on steel crossmembers | 28 mm (1-1/8″) marine-grade plywood on steel crossmembers rated for forklift traffic |
| Load rating | limited by axles, commonly 2,300-3,200 kg payload | structure rated over 28,000 kg gross |
| Weather shell | aluminum or FRP skin, sealed seams that need resealing | 14-gauge corten steel, welded seams, marine door gaskets |
| Access | rear ramp or barn doors at axle height | ground-level double doors, full 2.34 m opening width |
The access line matters more than people expect. A trailer deck sits at axle height, so everything you store climbs a ramp going in and coming out. A container floor sits at ground level on its blocking: a loaded dolly, a ride-on mower, or an appliance cart rolls straight in. If you are between sizes, the container size decision guide (and the interactive finder on it) walks the choice in four questions, and the 40ft container exists for the day one trailer’s worth is not enough.
Which Is Harder to Break Into, or Simply Tow Away?
Here is the uncomfortable fact about storing valuables in a trailer: it has wheels and a coupler, and that makes the whole box the easiest thing on your property to steal. The theft pattern is not someone picking your lock at midnight. It is a pickup backing up to the hitch, and your trailer, contents and all, leaving at highway speed. Coupler locks and wheel boots slow that down; none of them turn a road vehicle into a fixed structure.
A 20ft container weighs about 2,300 kg empty and has no wheels. Removing one from your property requires a tilt-deck truck or a crane and a visible, unhurried operation. On the door side, the corten shell resists cutting in a way sheet aluminum does not, and a welded lockbox over a puck lock shields the padlock from bolt cutters entirely. Farm insurers and rural OPP detachments have said versions of the same thing for years: thieves take what leaves quickly. A sea can does not leave quickly.
The Contractor’s Tool Crib
The classic convert is the contractor who stored tools in a 7×14 trailer until the morning it was gone. The replacement is a 20ft Wind and Watertight bin behind the shop with a lockbox and the tools shelved on racking, while a smaller open trailer handles the actual hauling. Each machine doing the job it was built for.
Storing, Not Hauling?

When the Enclosed Trailer Is the Right Call
We would rather lose a sale than talk you out of the right tool. Buy the enclosed trailer when:
- You genuinely haul. Job sites, race days, markets, moves between properties: if the box needs to travel monthly, it needs wheels. No container competes with that.
- The box must follow the work. A landscaping crew whose “storage” is really rolling inventory should own the trailer, full stop.
- Your site cannot take a delivery truck. A tilt-deck needs clear access and room to slide the bin off; our delivery guide shows exactly what that looks like. The odd tight urban lot is trailer territory by default.
- You already own the tow vehicle and use it. The trailer’s rolling costs stop being dead weight the day they earn their keep on the road.
If you read that list and thought “honestly, mine would just sit”, the rest of this page already made your decision. Some buyers land on both: a container for the standing storage, and a cheaper open utility trailer for the occasional haul, which together often cost less than one large enclosed trailer.
How Buying From a Real Yard Works
The used-trailer market and the used-container market share a problem: marketplace listings with a deposit request and no yard behind them. The pattern we warn container buyers about applies verbatim to trailer shopping. Many people call us saying they found a bin for $1,000 less on Facebook. Two weeks later they call back saying they got scammed. Do not send a deposit to a listing you cannot walk up to, for either product.
Buying from us works the way buying should. You pick your exact unit at our Brantford yard, in person or over a video call, every bin identified by its own container number. We photograph that unit and its CSC plate so you see the steel before you commit. Our driver calls before the run and places the bin where you point. You pay when it is on your ground, not before. Grades run from new (one-trip) down through Cargo Worthy, Wind and Watertight, and As-Is, and we will tell you straight which one your use actually needs.
Paul LeBlanc, owner: “A fellow from Cambridge priced a 16-foot enclosed trailer for his landscaping tools three summers running. Every spring the quote went up and every winter his neighbour’s trailer grew another tarp. He bought a 20-footer from us instead, put the difference into racking, and told me the best part is that it is exactly where he left it every morning.”

Frequently Asked Questions
Is a shipping container or an enclosed trailer better for storage?
For storage that stays put, the container. A 20ft sea can holds 33.2 cubic metres against roughly 20-21 for a 7×16 trailer, sits at ground level, has no tires or bearings to maintain, and cannot be hitched and towed away. Buy the trailer when the box genuinely needs to travel.
Do I need to plate or insure a trailer that just sits on my property in Ontario?
Trailers in Ontario are registered as vehicles, and coverage for a parked trailer depends on your policy and how the trailer is used, so confirm your situation with your own broker. A shipping container is not a vehicle: once delivered it is simply equipment you own, with no plate or renewal attached.
How much more does a 20ft container hold than a 7×16 enclosed trailer?
Roughly half again more. A 20ft container offers 33.2 cubic metres and a 2.39 m interior height, while a typical 7×16 enclosed trailer offers about 20-21 cubic metres under a 1.98 m ceiling. The container also carries it on a 28 mm marine-plywood floor rated for far heavier loading.
Can a shipping container be moved again later like a trailer?
Yes, just not by you on a Tuesday night, which is the point. A tilt-deck truck lifts and relocates an empty container in one visit. Day to day it stays where it was placed, which is exactly what you want from a box holding your tools.
What happens to an enclosed trailer that sits unused for years?
Trailer service shops document it well: tires flat-spot and crack, bearings pit, brakes seize, and roof and door seals dry out until water finds the plywood. A parked trailer needs storage-prep maintenance every year to avoid this. A container parked the same way needs a hinge oiling.
How fast can Van Blanc deliver a container in Ontario?
1-3 days to most of the province from our 4 Brantford yards, with every quote carrying a real lead time, not a hopeful one. Tell us the size and your postal code and the quote covers the bin and delivery together.
