What Does CFIA Require of a Food-Grade Container?
A food-grade container is a One-Trip steel box finished inside with smooth, cleanable, non-absorbent surfaces, sealed seams, proper floor drainage, potable water, and controlled temperature so the food business operating inside it passes a Safe Food for Canadians Regulations inspection. CFIA regulates the business, not the steel. The interior fit-out is what makes the box compliant.
The Canadian Food Inspection Agency does not certify shipping containers directly. CFIA enforces the Safe Food for Canadians Regulations (SOR/2018-108), and those regulations apply to the food business operating inside the container, not to the steel box itself. The container has to support compliance: smooth, cleanable, non-absorbent surfaces; no harbourage points for pests or moisture; properly drained floors; potable water; controlled temperature where required; and waste removed cleanly. A bare One-Trip container does none of that out of the gate. A finished food-grade build does all of it because the fabricator engineered the interior to pass a CFIA inspection.
SFCR Part 4 (Preventive Controls) is the section that drives the interior design. It calls for surfaces in contact with food to be smooth, durable, corrosion-resistant, non-toxic, and easy to clean and sanitize. It calls for the design to prevent contamination, including dead spaces where water or product can pool. It calls for adequate lighting at the work surfaces, ventilation that controls condensation, and pest exclusion at every penetration. Each of those clauses translates into specific build details that lean on the deep-clean and seal work we walk through for Ontario food jobs, including stainless coves between floor and wall, FRP panel seams sealed with NSF-rated silicone, conduit penetrations grommeted to prevent rodent entry, and so on.
What “Food-Grade” Means in Plain English
A food-grade container is one where every surface that could ever touch food, food packaging, or food-contact equipment is made from a material approved for food contact. That means stainless steel sheet, FDA-compliant FRP wall panels, NSF-listed flooring, and BPA-free epoxy where epoxy is used. The standard reference is 21 CFR 175.300 (FDA food-contact coatings), which Canadian fabricators follow because Health Canada accepts equivalent compliance. ISO 22000 references the same material classes for food safety management systems.
Do You Need an SFCR Licence for a Food Container in Ontario?
An SFCR licence for a food container in Ontario is only required when the business trades across provincial lines, exports, or handles a regulated commodity class. Most container food businesses fall into one of three regulatory buckets, and the answer to “do I need a CFIA licence?” depends entirely on which bucket. A coffee container parked on private property selling locally roasted bags to walk-up customers needs a municipal business licence and a public health permit, not a federal CFIA licence. A meat-processing container that ships product across the Ontario-Quebec border needs an SFCR licence, traceability records, and a written Preventive Control Plan. A commissary kitchen container that supplies a fleet of food trucks needs the public health permit plus, depending on the product class, sometimes an SFCR licence.
The trigger is interprovincial trade, export, or specific commodity classes (meat, fish, dairy, eggs, fresh fruit, fresh vegetables, processed products, honey, maple). If the business sits entirely within Ontario and stays clear of those commodity classes, the regulatory layer is the local public health unit operating under the Ontario Food Premises Regulation (O. Reg. 493/17), not CFIA directly. The container build still has to meet the same physical standards because public health inspectors enforce equivalent surface, drainage, and ventilation requirements. The paperwork shrinks; the steel does not.
The Ontario Reality Most Operators Miss
Brant County Public Health, Haldimand-Norfolk Health Unit, and Hamilton Public Health all inspect food premises the same way they inspect a brick-and-mortar restaurant: walk-through, surface check, thermometer probe in the cooler, hand-sink water temperature test, grease trap inspection. The fact that the kitchen is in a sea can changes nothing about how the inspection runs. Operators who treat the container like a permanent restaurant pass first time. Operators who treat it like a temporary stall fail and pay for rework.
Christian LeBlanc, second-generation operator: “An operator called us once convinced he needed a federal CFIA licence for a coffee container he was parking in one Brantford lot. He did not. He needed the public health unit and a clean interior. We sell him the One-Trip shell, we deliver it, and we point him at a fabricator who knows what the inspector wants. We grew up around containers, so we know the steel side cold. The licence side belongs to the operator and their health unit, and we never pretend otherwise.”
Why Is One-Trip the Only Honest Starting Shell?
The right starting shell for a food-grade build is a One-Trip container, not a used one. Used containers are fine for storage, equipment shelters, and dozens of conversion projects. A food-grade build is not one of them. A Cargo Worthy or Wind & Watertight container has multiple ocean crossings on it, which means residual hydrocarbon staining on the floor, possible chemical residue from previous cargo, surface rust under the paint, and dents in the corrugated walls that fight a smooth interior finish. We break down what each of those grades really means when you are shopping a used unit.
For food work, the standard is a One-Trip 20ft or 40ft High Cube. The interior steel is essentially new, the marine plywood floor (if present) is replaced with stainless or FRP-finished sheathing in the conversion, and the exterior paint is uniform for a clean post-conversion wrap or logo application. The modest premium for a One-Trip shell pays for itself in saved prep labour and lets the fabricator hit the finish spec on schedule. Every food-grade fabricator we deal with refuses to bid on a used shell. That is not a quirk; that is the trade telling you what works.
Marine Plywood Floor: Replace It or Live With It?
One-Trip containers ship with a 28mm marine plywood floor treated with a wood preservative (typically tributyltin oxide or basic copper carbonate). Those treatments are legal but not food-grade. For a coffee or dry-goods container, sealing the existing floor with two coats of BPA-free epoxy primer plus a topcoat is usually accepted. For a wet kitchen with grease, water, and protein handling, the plywood comes out and gets replaced with closed-cell foam, plywood underlayment, and a welded stainless tray with coved corners. Budget for the floor swap depending on container size.
How Is the Interior Stack Built (Floor, Walls, Ceiling, Seams)?
The interior stack of a food-grade container is built in layers, and the order matters. The fabricator starts with closed-cell spray foam on the walls, ceiling, and (in cold storage builds) the floor. Closed-cell spray foam is rated under one perm at two inches or more, so it functions as its own vapour barrier on the steel skin. Above the foam goes a layer of FRP (fibreglass-reinforced plastic) wall panel or 304 stainless sheet, fastened with stainless screws into furring strips that pass through the foam to the steel below. Every seam is silicone-sealed with an NSF-listed sealant rated for repeated wash-down.
The floor stack is different. After the marine plywood swap, the build goes: closed-cell foam (only if the use needs thermal control), plywood underlayment, NSF-listed sheet vinyl or welded stainless tray, coved up the wall four inches to eliminate the floor-to-wall crack that everything else hides in. The ceiling is FRP or stainless, sloped slightly toward the door wall to push condensation away from prep areas. Lighting is LED, NSF-rated, sealed gasket fixtures. Ventilation penetrations are foamed and sealed before the panels go on, all of which has to survive the daily chlorine wash-down a finished kitchen lives through.
Paul LeBlanc, owner: “We have been selling containers since 1995. Food-grade is the build I send to a fabricator every single time because the layers have to be right and the inspector has to be able to drag a paper towel across every surface without snagging. We supply the shell, we deliver it to their shop or to the customer’s site, and we step back. The fabricators who do this well in Ontario know what an inspector wants on the first pass. We never pretend we do that part in-house.”
What Flooring Is Approved, and Is BPA-Free Epoxy Safe?
Approved food-grade container flooring comes down to three working systems, and the floor choice is where most builds get expensive. There are three working options and one option that gets used badly and creates problems within a year. The working three are welded 304 stainless tray with coved corners, NSF-listed sheet vinyl (Altro, Polyflor, similar brands) with heat-welded seams and coved edges, or a poured BPA-free epoxy system from a manufacturer rated to 21 CFR 175.300 with coved corners formed wet. All three pass CFIA, all three pass Ontario public health, and all three handle a daily wash-down with hot water and chlorine sanitizer.
The fourth option is rolled-on garage epoxy from a big-box store. It says “food-safe when cured” on the label and that is technically true if the cured product is tested under FDA 21 CFR 175.300. Most retail garage epoxies are not tested to that spec, even when the label suggests they are. They crack at the coves, lift at the door threshold under heavy traffic, and turn yellow under hot water and chlorine. We see this happen on container kitchens that tried to save on the floor and end up gutting and redoing it 14 months later. Budget the floor properly the first time.
Food-Grade Floor Option Comparison
| Floor system | Service life (20ft) | Best use | Passes CFIA + Ontario PH |
|---|---|---|---|
| Welded 304 stainless tray, coved corners | 30+ years | Wet kitchens, meat processing (gold standard) | Yes |
| NSF sheet vinyl, heat-welded seams (Altro, Polyflor) | 15 to 20 years | Coffee, baking, dry goods (working standard) | Yes |
| BPA-free poured epoxy, FDA 21 CFR 175.300 | 10 to 15 years | Combined wet/dry use when rated correctly | Yes |
| Big-box rolled garage epoxy | Often fails inside 14 months | None for food work, gut-and-redo trap | No |
What Hood, Make-Up Air, and UL 300 Suppression Are Needed?
A container kitchen with any cooking line (range, fryer, char-broiler, flat-top, oven) needs three things together: a Type I commercial hood, a make-up air unit, and a UL 300 wet-chemical fire suppression system. UL 300 is the standard that replaced the older dry-chemical systems in 1994 because modern vegetable-oil fryers produce fires that dry chemical cannot extinguish. A hood with UL 300 suppression and the matching make-up air unit is one of the single largest line items in the build, and that holds true even though the container itself is only 160 square feet. The hood does not care that the kitchen is small.
Make-up air is the part that surprises operators. A commercial hood exhausts 1,200 to 2,400 cubic feet per minute. Without make-up air introducing replacement volume at the same rate, the container goes negative-pressure, doors stop closing properly, the hood stops capturing smoke, and the staff get a headache by hour three. The make-up air unit also tempers the incoming air in winter (Brantford January at minus 18 is not a friendly intake stream), which adds heater capacity and electrical load on top of the unit cost. Reg. 332/12 Section 6 (Heating, Ventilating and Air-Conditioning) governs commercial kitchen exhaust in Ontario. The hood must be tested to NFPA 96 (Standard for Ventilation Control and Fire Protection of Commercial Cooking Operations), and the fire suppression to UL 300. The municipal building department signs off on the install, the local fire department signs off on the suppression system, and the public health unit signs off on the cleanability of the hood interior. Three separate inspections; one well-sequenced build avoids three rounds of rework.
How Are Plumbing, Grease Trap, and Hot Water Sized?
Plumbing for a food-grade container starts with three water lines: hot, cold, and waste. The hand sink and the three-compartment sink need separate piping (hand-sinks cannot share waste with prep sinks under O. Reg. 493/17). Hot water needs to hit 60 Celsius at the hand sink and 71 Celsius at the sanitize compartment of the three-compartment sink, which means a tankless or 30-gallon tank water heater sized for the simultaneous demand of two or three fixtures. A 12kW tankless or a 6kW electric tank usually handles a single-line kitchen; doubles up to 18kW for a fryer-heavy line that runs constant dishwashing.
Grease trap is non-negotiable for any cooking line. A 20gpm passive trap (about the size of a microwave) sits under the three-compartment sink and serves a 20ft container kitchen comfortably. A 40gpm trap is the standard for a 40ft kitchen with multiple cooking stations. Pump-out service from Brantford-area liquid waste contractors. The trap is not optional in any municipality; without it, the kitchen fails inspection on day one and the operator pays the public health unit’s order-to-rectify fee plus the rework.
What Electrical Service and ESA Certification Are Required?
Electrical service for a working container kitchen in Ontario almost always needs 100 amp single-phase service or 60 amp three-phase, depending on the equipment mix. A flat-top, a fryer, a refrigerator, a freezer, a hood and make-up air unit, a water heater, and lighting on a single 60 amp panel will trip the main breaker at lunch rush. Sizing the service correctly the first time keeps the panel and feeders cost contained; resizing after the rough-in is done costs several times as much and delays opening. The Electrical Safety Authority (ESA) inspects every commercial container build in Ontario and issues the certificate that public health needs to see before they will issue the food premises operating licence.
Refrigeration deserves its own callout. A reach-in cooler at 4 Celsius and a reach-in freezer at minus 18 Celsius pull combined 12 to 16 amps continuous in a Brantford August. If the kitchen also runs a walk-in cooler (an attached reefer container or a built-in box), that adds another 20 to 30 amps. Size the panel for peak summer load, not for the spec sheet nameplate, because the compressors cycle longer when the ambient is 33 Celsius outside the container wall. We have seen too many builds where the electrician sized for spec and the operator runs an extension cord to a generator on the hot days.
What Drives a Food-Grade Conversion Cost in 2026?
What drives the cost of a turnkey food-grade container conversion in Ontario is the build tier, not the steel. Four tiers cover most projects, listed from lightest to heaviest scope: a 20ft coffee or bakery container with a sink line, basic hood, and full finish on top of the One-Trip shell; a 20ft full hot-line kitchen with hood, make-up air, fire suppression, three-compartment sink, hand sink, fryer, flat-top, and refrigeration; a 40ft High Cube full commissary kitchen for a food truck fleet, with separate prep, cook, and dishwash zones; and a reefer-style cold storage container for a butcher or seafood operation. Each step up adds equipment, electrical load, and certified labour, which is where the cost climbs.
The quote moves with the cooking line, the refrigeration load, the flooring spec, and the inspections the build has to clear, not with the size of the box. Anyone quoting a turnkey hot-line kitchen container far below the working market range is either skipping the hood, skipping the fire suppression, using uncertified flooring, or building it offshore and shipping it in (which creates its own CBSA import classification problems). The cheaper Facebook bin pattern shows up in conversions too: the suspiciously cheap “turnkey food kitchen” listing is the conversion equivalent of the disappearing sea can.
The Shell Cost Versus Build Cost Ratio
The container itself is only 4 to 8 percent of the finished food-grade build cost. A One-Trip 20ft shell becomes a finished bakery once the fabricator has done the real work inside it. Spending a little more on a factory-fresh One-Trip box graded at our yard, with a clean interior and zero residue, eliminates fabricator delays and prevents the kind of rework that adds to a schedule. The shell is the cheapest line item in the whole build; do not save money there.
Who Actually Builds These (and Why Don’t We)?
Who actually builds food-grade container interiors is a specialty fabrication trade, not the container yard. Van Blanc sells One-Trip and used shipping containers from our 4 Brantford yards. We deliver across Ontario in 1 to 3 days. We do not build food-grade interiors in-house. That is a specialty trade that requires NSF-listed material inventory, certified welders for stainless cove work, ESA-licensed electrical contractors, plumbing crews registered with the municipality, hood and fire-suppression installers certified by the manufacturer, and a fabrication shop set up to handle the work indoors during Ontario winters. We have seen container suppliers try to build food-grade in-house and fail the inspection three times before realizing the work needed a different trade.
What we do is supply the right shell at the right price, deliver it to the fabricator’s shop or to the customer’s chosen site, and stay out of the conversion build. The same split applies to every project in the range of builds a sea can can become, from cold storage to retail. A licensed-trades fit-out is also exactly how a hospitality build like a bar or restaurant container comes together, so the food-service playbook here is not unique to kitchens. The fabricators we refer to in the Greater Toronto, Hamilton, and Waterloo regions are real operations with reference projects you can visit. We do not take a commission on the referral. We sell the container; they build the kitchen; the operator opens a working business. Three parties, three clear roles. That is the honest answer when an operator calls asking if we can turnkey a food-grade build.
The Brantford Bakery That Bought the Shell From Us
A new operator picked up a One-Trip 20ft from our yard in late 2025, hauled it to a fabricator in Cambridge, and opened a wholesale bakery container in a Hamilton industrial park three months later. The shell was a small fraction of the total project. The fabricator build was turnkey, including a four-rack oven, a stainless prep table, a hand sink, a two-compartment sink, BPA-free epoxy floor, and a UL 300 hood over the oven exhaust path. Brant County Public Health passed it on the first inspection because every interior surface was specified correctly from day one. We saw the operator back in our yard a year later picking up a second shell for a sister location.
What Does Delivery Day Look Like From Our Brantford Yard?
Delivery day for a food-grade shell looks the same as any One-Trip delivery from our 4 Brantford yards: a tilt-deck truck, a real lead time of 1 to 3 days, and an exact placement on the fabricator’s pad or the operator’s site. The fabricator typically wants the container delivered to their indoor shop because the interior build runs four to eight weeks and Ontario weather is not friendly to closed-cell spray foam install in a parking lot. Once the build is complete, the finished food-grade container moves on a flatbed (it is heavier than a stock container because of the stainless, hood, and equipment) to its final site.
Operators occasionally try to have the fabricator build at the final site to save on the second move. That works for rural or large-pad commercial sites; it does not work for urban downtown installs where the fabricator’s crew and the shore power are simpler at their own shop. We have hauled finished kitchens from Cambridge to Hamilton, Mississauga, Toronto, Burlington, and Kitchener over the past two years. The fabricators tell us when they are ready; we book the haul. Before any kitchen ships, the fabricator runs a final interior sanitation and seal check so the operator opens with a verified-ready surface on day one.

Frequently Asked Questions
Does CFIA certify shipping containers as food-grade?
No. CFIA enforces the Safe Food for Canadians Regulations (SOR/2018-108) against the food business, not the container. The container itself is not certified; the interior fit-out must meet SFCR Part 4 preventive control requirements (smooth, cleanable, non-absorbent surfaces, proper drainage, pest exclusion, temperature control). The food business then applies for an SFCR licence (if required by their trade pattern) or a public health permit (for Ontario-only operations).
Do I need a CFIA SFCR licence to operate a food container in Ontario?
Only if the business trades interprovincially, exports, or handles specific commodity classes (meat, fish, dairy, eggs, fresh produce, processed products, honey, maple). Ontario-only operations selling locally fall under O. Reg. 493/17 (Ontario Food Premises Regulation) and the local public health unit, not CFIA directly. The container build must still meet equivalent physical standards because public health inspectors enforce the same surface, drainage, and ventilation requirements.
What flooring is approved for a food-grade container in Canada?
Welded 304 stainless tray with coved corners, NSF-listed heat-welded sheet vinyl (Altro, Polyflor), or BPA-free poured epoxy rated to FDA 21 CFR 175.300 with coved corners formed wet. All three pass CFIA and Ontario public health. Big-box rolled garage epoxy is not approved, even when the label says “food-safe when cured”, because retail products are rarely tested to the FDA spec.
Is BPA-free epoxy actually safe for direct food contact?
Yes, when the specific product is rated to FDA 21 CFR 175.300 (food-contact coatings). Industrial products like ChemLINE WS and ChemLINE AS are tested BPA-free and FDA-compliant. The compliance is product-specific; the phrase “BPA-free” alone on a label is not enough. Ask the fabricator for the technical data sheet showing 21 CFR 175.300 compliance before approving the floor spec.
How much does a food-grade container kitchen cost in Ontario?
The cost rises with the build tier, not the steel. From lightest to heaviest, the four common builds are a 20ft coffee or bakery container with a sink line and basic hood, a 20ft full hot-line kitchen with hood and fire suppression, a 40ft commissary kitchen with separate prep, cook, and dishwash zones, and a reefer-based cold storage room. Each step up adds equipment, electrical load, and certified labour. A hot-line kitchen quote that comes in far below the working market range is almost always missing the hood, the fire suppression, or proper flooring. The shell itself is only 4 to 8 percent of the finished cost.
Why does the fire suppression have to be UL 300?
UL 300 is the wet-chemical fire suppression standard that replaced older dry-chemical systems in 1994. Modern vegetable-oil fryers produce fires that dry chemical cannot extinguish; UL 300 wet chemical does. NFPA 96 (Standard for Ventilation Control and Fire Protection of Commercial Cooking Operations) requires UL 300 over any cooking equipment that produces grease-laden vapours. We sell One-Trip and used shipping containers from our 4 Brantford yards and deliver across Ontario in 1 to 3 days. Food-grade conversions are a specialty trade requiring NSF inventory, certified stainless welders, ESA electrical contractors, registered plumbers, and hood and fire-suppression installers. We refer to fabricators in Cambridge, Hamilton, and the Greater Toronto Area who actually build to spec. We take no commission on the referral.
What is the right starting shell for a food-grade build?
One-Trip 20ft or 40ft High Cube, always. Used Cargo Worthy or Wind & Watertight containers have residual hydrocarbon staining, possible chemical residue, surface rust, and dents that fight the smooth interior finish. Every food-grade fabricator we work with refuses to bid on a used shell because the prep cost exceeds the One-Trip price premium. The modest premium for a One-Trip shell is more than offset by the prep labour it saves.
How long does a food-grade conversion take from shell to opening?
Four to eight weeks in the fabricator’s shop once the shell arrives, plus another two to four weeks for site work, utility hookups, and the three inspection rounds (building, fire, public health). Most Ontario food-grade container builds go from order to opening in three to four months. The schedule slips when shells arrive late or when the fabricator is bidding on multiple jobs; our standard 1 to 3 day shell delivery from Brantford keeps the front end of that schedule tight.
Can I use a refrigerated container as a food-grade cold storage room?
Yes, with the right interior fit. A One-Trip 20ft or 40ft High Cube reefer ships with food-grade aluminum or stainless interior panels and a T-floor designed for forklift wash-down. The build adds NSF-listed shelving, sealed LED lighting, a thermometer with calibration record-keeping, and a logged temperature alarm. A cold-storage conversion is one of the lighter food-grade builds because the reefer shell already provides the insulated, washable interior, so the added cost sits mostly in the fit-out rather than the structure. We sell reefer shells from our Brantford yard and deliver across Ontario.
