Quick Answer: Standard reference: CFIA: Food Safety & Cold Chain. A “freezer container” in industrial Canadian usage is a refrigerated shipping container (reefer) operating in freezer mode at -18°C to -30°C. The same 20ft or 40ft High Cube reefer that handles chilled cargo at +4°C can run at freezer temperatures by adjusting the controller. Refrigeration units come from Carrier Transicold, Thermo King, or Daikin integrated into CIMC Corten steel envelopes. In Canada 2026, what you pay for a freezer container is driven by size, grade (Cargo Worthy versus One-Trip), the age and brand of the refrigeration unit, and your delivery distance, and the monthly running cost rises as you push the setpoint from chilled toward deep freeze. Van Blanc carries reefer containers at our Brantford yard for restaurants, food processors, cannabis producers, ice cream operators, and any business needing turnkey frozen storage.

What Drives the Price of a Reefer or Freezer Container?
Four inputs set every reefer quote, and none of them is your postal code alone. First, whether the refrigeration unit is working or the box is selling as an insulated shell: a running unit is most of the value. Second, the machine’s age and hours, because the Carrier and Thermo King units above have service lives of their own. Third, power: a unit specced for 3-phase costs differently to run than one paired with a genset, and the power-supply guide covers that fork. Fourth, delivery distance from the Brantford yard. Tell us the cargo, the temperature target, and the site power, and the quote comes back with a real all-in number, usually the same day: 519-754-6844. The wider reefer world lives in the refrigerated container hub.

When industrial Canadian buyers say “freezer container,” they mean a refrigerated shipping container (industry term: reefer) running at frozen storage temperatures, typically -18°C for standard frozen and -25°C to -30°C for deep freeze. This is the same 20ft or 40ft High Cube reefer used for chilled cargo at +4°C in dairy and produce, just with the controller set to lower temperatures. The container is identical; only the operating temperature changes.
This guide explains what makes a shipping container into a freezer, the refrigeration technology from Carrier Transicold, Thermo King, and Daikin, the operating cost math at freezer temperatures, the Ontario use cases that drive freezer container demand, and what you actually pay for a turnkey industrial freezer storage solution in 2026. If you are weighing chilled operation as well as frozen, our broader rundown of how refrigerated containers work and what they cost in Canada sits one level up from this freezer-specific guide.
What is a freezer container?
A freezer container is a refrigerated shipping container, called a reefer in the trade, run in freezer mode at -18°C to -30°C. The insulated steel envelope holds the cold, and an integrated unit from Carrier, Thermo King, or Daikin does the cooling. The same box also runs as a chiller at +4°C; only the setpoint changes.
That short definition covers the hardware. The word itself, though, points at two completely different products in 2026 Canadian usage:
Household / kitchen meaning
In retail and household contexts (Walmart, Canadian Tire, Amazon), “freezer container” refers to small Tupperware or glass containers designed for freezing food portions at home. These are kitchen-product searches, not the topic of this guide.
Industrial / commercial meaning
For Ontario businesses, food processors, cannabis producers, restaurants, and any operation needing serious frozen storage capacity, “freezer container” means a refrigerated shipping container (reefer) operating at frozen temperatures. This is what we deliver from our Brantford yard.
The technical industry term is “reefer container,” but Canadian buyers commonly say “freezer container” when they specifically need frozen rather than chilled operation. The equipment is the same; if you want the full breakdown of where each setpoint lands, we cover it in our walkthrough of how far a reefer setpoint can swing for cold-chain work in Ontario.
Paul LeBlanc, who founded Van Blanc in 1995 and has spent 19 years in the container trade, puts the buyer confusion plainly. “People phone asking for a freezer and a chiller like they are two different machines,” he says. “It is one reefer. We set it to -18 for frozen, we set it to +4 for dairy, and we show them the controller in the yard before they ever pay.”
Temperature ranges: chilled vs freezer vs deep freeze
Modern reefer containers can hold temperatures across a wide range. Buyers should know which temperature their operation needs:
| Operating Mode | Temperature Range | Common Cargo |
|---|---|---|
| Ambient / room temp | +15 to +25°C | Dry goods that need protection from heat |
| Chilled storage | +2 to +8°C | Dairy, produce, beer, wine bottling buffer |
| Standard refrigerated | 0 to +4°C | Fresh meat, fish, prepared food, vaccines |
| Standard freezer | -18 to -20°C | Most frozen food, ice cream, frozen meat, baked goods |
| Deep freezer | -25 to -30°C | Long-term frozen storage, sashimi-grade fish, premium ice cream |
| Ultra-low / cryogenic | -30 to -65°C | Pharmaceutical biologics, specialty research samples |
Standard freezer mode (-18°C)
The most common Canadian freezer-container application. Food Safety Authority (CFIA) standards for frozen food storage require maintaining -18°C or below. This is the operating point that supports most commercial frozen food, cannabis flower curing storage, ice cream production buffer, and frozen meat distribution.
Deep freezer mode (-25 to -30°C)
For premium frozen products (sashimi-grade fish, premium ice cream brands, scientific samples), -25°C to -30°C is standard. Operating cost is meaningfully higher than -18°C because the refrigeration unit runs harder.
Beyond -30°C (specialty)
Carrier NaturaLINE and Star Cool premium units can hold temperatures down to -40°C in some configurations. Below -30°C the operating cost increases substantially and specialty pharma-grade containers are typically used.
The refrigeration unit makers (Carrier, Thermo King, Daikin)
Every reefer container has two parts: the Corten steel insulated envelope (built by CIMC, Maersk Container Industry, Singamas, or other major manufacturer) and the refrigeration unit (built by Carrier Transicold, Thermo King, or Daikin). The refrigeration unit determines temperature performance, energy efficiency, and reliability.
Carrier Transicold
The dominant reefer refrigeration unit manufacturer worldwide. Key product lines:
- PrimeLINE®: Premium unit, 20-30% more energy efficient than competitors. EcoDriven technology reduces fuel consumption during genset operation.
- NaturaLINE™: Uses CO₂ (R-744) as refrigerant instead of synthetic HFC refrigerants. Industry-leading sustainability.
- OptimaLINE™: Mid-tier unit balancing efficiency and price.
- Heritage units: Legacy models still in service across the global fleet.
Performance: temperature range -30°C to +30°C standard, with advanced variants reaching -40°C. Scroll compressor or reciprocating depending on model.
Thermo King
Trane Technologies subsidiary, leader in transport refrigeration since 1938. Competes head-to-head with Carrier in the container reefer segment. Known for:
- Scroll compressor technology for fast efficient cooling
- Even airflow distribution across container interior
- Energy efficient long-life units
- Strong North American service network
Daikin
Japanese refrigeration manufacturer, third major reefer brand globally. Increasingly integrated with CIMC envelopes for new builds. Strong Asia-Pacific presence with growing North American market share.
Star Cool (now part of CIMC)
Maersk Container Industry developed the Star Cool platform before its 2021 acquisition by CIMC. Star Cool is the premium reefer technology for pharmaceutical and biotech applications where temperature stability matters most. Extended atmosphere control capabilities for fruit and produce. Premium pricing reflects engineering pedigree.
What is the difference between a 20ft and 40ft freezer container?
A freezer container comes in two standard sizes: the 20ft reefer and the 40ft High Cube reefer. The 20ft holds about 28 cubic metres of insulated space and suits a single restaurant or a small processor; the 40ft HC holds about 66 cubic metres and dominates the Canadian secondary market because it carries far more product per dollar of refrigeration. Both run the same -30°C to +30°C range; the gap is volume, footprint, and weight, laid out below.
| Specification | 20ft Reefer | 40ft HC Reefer |
|---|---|---|
| External dimensions | 6.06 × 2.44 × 2.59 m | 12.19 × 2.44 × 2.90 m |
| Internal dimensions | 5.45 × 2.29 × 2.27 m | 11.59 × 2.29 × 2.50 m |
| Internal volume (insulated) | 28.3 m³ | 66.3 m³ |
| Insulation thickness | 75-100 mm polyurethane foam | 75-100 mm polyurethane foam |
| Tare (empty) weight | 3,000-3,200 kg | 4,500-4,800 kg |
| Max payload (cargo capacity) | 20,800 kg | 25,680 kg |
| Floor type | Aluminum T-bar with air channels | Aluminum T-bar with air channels |
| Refrigeration power draw | 3-4 kW continuous | 4-6 kW continuous |
| Required power supply | 3-phase 380-460V | 3-phase 380-460V |
| Temperature range | -30 to +30°C standard | -30 to +30°C standard |
Why reefer interiors are smaller than dry containers
The 75-100mm insulation envelope reduces internal dimensions versus dry containers. A 40ft HC reefer has 66.3 m³ of usable volume; a 40ft HC dry container has 76.3 m³. The 13 percent reduction is the cost of refrigeration capability. The floor is also different (aluminum T-bar with integrated air channels rather than the plywood floor of dry containers) to support cold-air circulation under cargo pallets.
How much does it cost to run a freezer container per month?
The monthly running cost of a freezer container is your hydro rate multiplied by the unit’s continuous power draw, and that draw depends on ambient temperature (Ontario climate), target setpoint, and the refrigeration unit’s efficiency. Because the energy bill tracks the continuous power draw, the table below shows realistic Ontario power consumption by mode, which is what your hydro rate is multiplied against:
| Operating Mode | 40ft HC Reefer (continuous draw) | 20ft Reefer (continuous draw) |
|---|---|---|
| Chilled at +4°C (winter) | 2-3 kW | 1.5-2.5 kW |
| Chilled at +4°C (summer) | 3-4 kW | 2-3 kW |
| Standard freezer -18°C (winter) | 3-4 kW | 2.5-3.5 kW |
| Standard freezer -18°C (summer) | 4-6 kW | 3-4 kW |
| Deep freezer -30°C (winter) | 5-7 kW | 3.5-5 kW |
| Deep freezer -30°C (summer) | 7-9 kW | 5-6.5 kW |
Power consumption math
A 40ft HC reefer at -18°C in Ontario summer draws approximately 4-6 kW continuous. That equals 96-144 kWh per day, or about 2,880-4,320 kWh per month. Multiply that monthly kWh figure by your own Ontario commercial electricity rate (including delivery and regulatory charges) to get the running cost for your site, since rates vary by utility and by time-of-use plan.
Winter operation is meaningfully cheaper because ambient temperatures are already cold. The compressor cycles less, drawing 2-3 kW average instead of 4-6 kW. Monthly cost drops by 30-40%.
Cost comparison: reefer container vs built walk-in freezer
Building a stick-built walk-in freezer of equivalent volume in Ontario carries a very different cost profile than buying a turnkey reefer:
- Construction: a poured pad, insulated shell, and finishing all priced as a custom build, with the bill set by your contractor and local labour rates
- Refrigeration system: specified, installed, and commissioned separately on top of the shell
- Total capital: the highest of the options here because shell and refrigeration are bought and built as two distinct projects
- Operating cost: broadly similar to a reefer at the same -18°C setpoint, since the physics of holding the same volume cold are comparable
- Lifespan: 15-25 years
A 40ft HC reefer arrives turnkey in Ontario as a single delivered unit, with the figure set by grade. The capital outlay is far lower than a stick-built room while the operating cost and lifespan are comparable, and because a reefer is one self-contained box it can be set down on a prepared pad in a single drop. We walk through exactly how that drop works, the truck, the access, and the site, in our breakdown of what to expect when your container is delivered across Ontario.
7 Ontario business use cases
1. Restaurants and food service
Restaurants needing additional frozen storage beyond their built-in coolers and freezers. Catering operations storing pre-prepped frozen meals. Food trucks operating from a single base location. A 20ft reefer delivered turnkey provides ~28 m³ of frozen storage, equivalent to 4-6 walk-in freezer doors. See our container restaurant guide for adjacent kitchen build context.
2. Cannabis production and curing
Licensed cannabis producers in Ontario use freezer containers for:
- Bud freezing for fresh-frozen extraction processes
- Long-term flower preservation at -18°C or lower
- Live resin and concentrate freezing
- Climate-controlled trimming room buffer
Cannabis Ontario operating costs include cold storage as a significant operational line; reefer containers reduce capital tie-up versus stick-built cold rooms.
3. Ice cream production and distribution
Ice cream operators (Chapman’s, Kawartha Dairy, regional producers, independent shops) need -25°C deep-freeze storage for product holding and -18°C for distribution buffer. A 40ft HC reefer at deep-freeze setpoint holds 60+ m³ of finished product.
4. Frozen meat distribution
Wholesale meat distributors, butcher shops, restaurant suppliers using freezer containers as turnkey distribution buffer. The relocatable nature of containers matters for seasonal volume changes.
5. Wine and beer cellaring
Niagara wine region operations use reefer containers in chilled mode (+12 to +14°C) for bottling-cycle storage. Beer breweries use chilled or near-freezing for cold-conditioning lagers. See our winery cold storage guide.
6. Pharmaceutical and biotech cold chain
Vaccine storage at -25°C, biological samples at -30°C, lab freezing. Carrier PrimeLINE and Star Cool units are the premium choices for pharma applications where temperature stability matters most.
7. Event and seasonal cold storage
Catering for large events, festival ice-cream operators, summer farm market frozen products, Christmas season frozen turkey distribution. Reefer containers solve seasonal cold storage spikes without permanent capital outlay.
Real Ontario 2026 cost by size and grade
Freezer container (reefer container) pricing in Ontario as of 2026:
| Size + Grade | Relative Cost Tier | Notes |
|---|---|---|
| 20ft Reefer Cargo Worthy | Most affordable entry point | 5-12 years old, CSC current, working refrigeration |
| 20ft Reefer One-Trip | Step up from used 20ft for newer refrigeration | 0-2 years old, new refrigeration unit, factory paint |
| 40ft HC Reefer Cargo Worthy | Best volume-per-dollar of the four | 5-12 years old, CSC current, working refrigeration |
| 40ft HC Reefer One-Trip | Top tier, newest unit and largest capacity | 0-2 years old, new refrigeration unit, factory paint |
Delivery from our Brantford yard is quoted on top of the container, scaled to your distance and access. Reefer delivery uses standard tilt-deck trucks (the container weight is heavier than dry but still within tilt-deck rating).
Why used reefers cost what they cost
The refrigeration unit is the major cost driver. A new Carrier PrimeLINE or Thermo King unit commands a substantial share of the total for the refrigeration component alone. A used unit (8-12 years post-manufacture) still has 5-15 years of remaining service life with normal maintenance, which is why used reefers retain meaningful resale value.
Wind & Watertight (WWT) grade rarely exists for reefers because once the refrigeration unit fails or becomes obsolete, the container is typically scrapped or stripped for parts rather than sold as WWT. Buyers wanting bare insulated containers without active refrigeration can sometimes source these as conversion donors below working-reefer pricing, and the quickest way to see which reefer grades are actually sitting on the ground right now is to check what we have in the Brantford yard today. If you want the newest possible refrigeration unit and factory paint, the One-Trip reefers we cover on our page for buying new containers in Ontario are the freshest stock we carry.
Cold-chain compliance for food and pharma
Freezer container operations in Ontario must comply with applicable food safety or pharmaceutical regulations:
CFIA food storage
Frozen food storage at commercial scale requires:
- Temperature monitoring with documented logs
- -18°C or below maintained continuously
- Door sealing and gasket integrity
- Cleanable interior surfaces (aluminum T-bar floor meets this)
- Pest exclusion
Modern reefers include telematic control units with GPS, temperature, humidity, and door status tracking. These data logs satisfy most regulatory documentation requirements.
Cannabis regulatory requirements
Health Canada licensed cannabis producers use freezer containers within their licensed premises perimeter. Temperature documentation and security are the main operational concerns; the reefer container hardware satisfies both with standard configurations.
Pharmaceutical cold chain
Pharmaceutical applications require validated temperature mapping, alarm systems for temperature excursions, and documented inspection schedules. Carrier PrimeLINE units with telematic monitoring are typical choices for pharma applications. Star Cool platform offers premium pharma-grade temperature stability.

Frequently Asked Questions
How cold does a freezer container get?
Standard reefer containers operate from -30°C to +30°C with most units. Standard freezer setpoint is -18°C (CFIA frozen food storage standard). Deep freezer applications use -25 to -30°C. Specialty pharma-grade units (Carrier NaturaLINE, Star Cool premium) can reach -40°C in some configurations. For ultra-low temperatures below -40°C, specialty cryogenic containers are required.
How much does a freezer container cost in Canada?
In Ontario 2026, four tiers cover most buyers, from least to most expensive: a 20ft Cargo Worthy reefer, then a 20ft One-Trip, then a 40ft HC Cargo Worthy, and finally a 40ft HC One-Trip at the top. Within each tier the quote moves with the age and brand of the refrigeration unit, the grade of the steel envelope, and the season, plus a separate delivery charge from our Brantford yard scaled to your distance. Call for a current, all-in number for your size and postal code.
How much does it cost to run a freezer container?
Running cost tracks power draw, which is 4-6 kW continuous for a 40ft HC at -18°C, lower in winter and higher in summer, and higher again at a -30°C deep-freeze setpoint. That works out to roughly 2,880-4,320 kWh per month, so multiply your own Ontario commercial electricity rate by that monthly kWh figure to estimate the cost for your site. Winter operation runs noticeably cheaper because the compressor cycles less when the outside air is already cold.
What is the difference between a freezer container and a reefer?
No difference in hardware. A “reefer” (refrigerated container) is the technical industry term; “freezer container” is buyer vernacular for a reefer specifically operating at freezer temperatures (-18°C to -30°C). The same 20ft or 40ft HC reefer can run as a chiller at +4°C, a standard freezer at -18°C, or a deep freezer at -30°C by adjusting the controller. The container is identical.
How long does a freezer container last?
20-25 years total service life for the integrated unit. The Corten steel envelope lasts 30-50+ years (same as dry containers, see our lifespan guide). The refrigeration unit typically needs major service or replacement at year 15-20. Many operators replace the refrigeration unit at year 18-25 and continue using the insulated envelope for another decade or more.
Can you store food in a shipping container freezer?
Yes, this is the primary commercial application. CFIA frozen food storage requires maintaining -18°C or below, which reefer containers handle continuously. Aluminum T-bar floor with air channels supports proper air circulation under pallet loads. Cleanable interior surfaces meet food safety standards. Modern reefers include temperature logging that satisfies regulatory documentation requirements.
Do freezer containers need special power?
Yes. Reefer containers require 3-phase 380-460V power, drawing 3-6 kW continuous depending on size and ambient conditions. Standard residential 120V/240V single-phase service is not adequate. Commercial 3-phase service installation (Hydro One or Hydro Ottawa or local utility) is required for stationary reefer operation. For remote sites without grid 3-phase, diesel generator (genset) operation is the alternative at higher operating cost. We break the wiring side down further in our note on getting three-phase service ready for a reefer at an Ontario site.
What size freezer container do I need?
For a small restaurant or food service operation: 20ft Reefer (28 m³). For ice cream production, cannabis facility, mid-size food distribution, or wine bottling buffer: 40ft HC Reefer (66 m³). For high-volume operations (large frozen food distributors, multi-product cold chain): two or more 40ft HC reefers. Most Ontario buyers in food service start with one 40ft HC and add capacity as operation scales.
Can I convert a regular shipping container into a freezer?
Possible but rarely economical. A refrigeration retrofit on a dry container means buying and fitting the refrigeration unit, insulation, controller, and power supply as separate parts, and the combined bill often approaches what a complete used reefer would cost. The result is meaningfully less efficient than a purpose-built reefer because the insulation thickness is limited. For most Canadian buyers, buying a used reefer container outright is cheaper and operates better than retrofitting a dry container.
