Quick Answer: Ontario’s veterinary facility standards require every mobile practice to have a stationary base unit: secure storage for drugs, equipment, and records. A converted shipping container, insulated, lined, lockable, and climate-controlled, is a base-unit shell that arrives in days. Van Blanc converts and delivers them across Ontario in 1-3 days.

The Rule Every Ontario Mobile Vet Already Knows

A mobile veterinary practice in Ontario is never only a vehicle. The College of Veterinarians of Ontario’s facility accreditation standards, the current edition approved by Council in December 2023, say a mobile unit has a stationary element called a base unit: a space for secure storage of equipment, supplies, pharmaceuticals, and medical records. The truck sees the patients. The base unit is where the practice legally lives, and accredited facilities are inspected on a five-year cycle to confirm it does its job.

The room that satisfies that requirement is an ordinary insulated conversion, which is the part of this we can genuinely help with.

The standards are specific about what that job involves. Controlled substances belong in a separate, locked storage area. Drugs that need temperature control need genuine temperature control, a refrigerator, not a hope. Surfaces where product and equipment live must be cleanable and impervious to fluids; the standards call out unsealed concrete as unacceptable. Water for cleaning means a drained sink with hot and cold supply. None of this is exotic. It is a small, secure, climate-controlled, washable room, and that description should sound familiar to anyone who has read the rest of our site.

The Base Unit Nobody Budgets For

Every guide to starting a practice on wheels walks through the vehicle build, the equipment list, and the service radius, and then waves a hand at the part Ontario regulates: where the drugs, records, and inventory live between calls. The default answers all have problems. A corner of the house means clients’ records and controlled substances in a residence. Subleasing a shelf at a colleague’s clinic means your inventory inside someone else’s accreditation and someone else’s hours. Renting commercial space means a full lease carrying a practice that, by design, is almost never there.

Empty container interior before fit-out, the blank room a base unit build starts from.

What the mobile model actually wants is a small dedicated building on ground the vet already controls: the driveway, the farm, the corner of a commercial lot. Small dedicated buildings that are secure, insulated, and deliverable happen to be our entire business.

Christian LeBlanc, second-generation operator: “Half the conversions we do at the yard are some version of the same brief: a locked, insulated, washable room with shelving, a door, and climate control. The profession on the sign changes. The room mostly does not.”

What Does a Vet Base Unit Need? The Container, Line by Line

Put the CVO storage requirements beside a fitted 20ft container and the mapping is almost one to one. A 20ft gives about 13.9 square metres of interior floor, which is more than a storage-focused base unit needs and small enough to sit beside a house without argument.

What the standards ask of base-unit storageWhat the fitted container answers
Secure storage for equipment, supplies, drugs, recordsCorten steel shell, lockbox-protected doors, optional man door with commercial lockset
Separate locked area for controlled substancesBuilt-in locked cabinet or partitioned locked bay, welded and anchored
Temperature-appropriate drug storageSpray-foam insulation, heat and cooling sized to the room, powered refrigerator inside
Cleanable, fluid-impervious surfacesLined and sealed walls and floor finish, no bare wood, no unsealed concrete anywhere
Sink with hot and cold water, drainedPlumbing rough-in at the yard; your licensed plumber connects and certifies on site
Records kept secure and retrievableDry, conditioned shelving bay away from the wash-down zone

The other half of the fit is operational. The container is deliverable, so the base unit can move if the practice moves. It is steel, so the insurance conversation about break-ins is short. And it is yours, so the practice’s regulated storage no longer depends on anyone else’s lease, hours, or goodwill.

The Large-Animal Variant: A Base Unit That Lives Where the Calls Are

Companion-animal mobiles are only half the story. Ontario’s large-animal and mixed practices spend their days on farm calls, and their storage problem is heavier and colder: fluids by the case, calving equipment, hoof gear, bulk supplements, and drug inventory that cannot freeze in a truck overnight in January. For those practices the base unit wants to live where the work is, at the home farm or a central rural property, not in a strip mall the vet drives away from at 6 a.m.

The Rural Setup That Keeps Coming Back

A 40ft, partitioned: the front third insulated, heated, and shelved as the regulated storage room with the locked drug cabinet and the records bay; the back two-thirds as cold-tolerant equipment bay for the gear that does not care. One delivery, one building, two rooms, and the January inventory problem is over.

The same partitioned build serves a second purpose that rural practitioners raise on their own: continuity. When an associate covers the practice or a locum takes the truck for a week, the base unit is the fixed point where the inventory, the records, and the controlled-drug custody stay orderly. A room with one key and a sign-out sheet survives staffing changes that a hatchback full of totes does not.

And because the shell is steel and the fit-out is bolted in rather than built in, the whole base unit can follow the practice if it relocates. That is a sentence no leased clinic corner can offer, and for a first-decade mobile practice still finding its territory, it matters more than it looks.

What We Build and What Your Licensed Trades Finish

Honesty about the build split, because it matters to an accreditation inspection. At our Brantford yard we do the shell work: insulation, lining, man doors, windows, security bars, lockboxes, shelving, partitions, venting, and climate units, converted before delivery under engineered drawings. The regulated connections are your licensed trades’ work: the plumber connects and certifies the sink, the electrician makes the final power connection. We rough in and document so their job is short, and we never sign for work that belongs to a licence we do not hold.

That same split is how our conversion program handles food service, offices, and retail builds, and it is the split an inspector expects to see paperwork for. If your fit-out brief already exists, send it with the quote request and we will price the shell build against it directly.

A Base Unit on Your Own Ground

Send us your storage list and your postal code. We will spec the container, the fit-out, and the trades split in one honest quote, usually back the same day.

The College Owns the Accreditation; You Own the Practice

A supplier who promises a pre-accredited building is selling something that does not exist. Accreditation belongs to the College of Veterinarians of Ontario, runs through your facility director, and is assessed against the standards as your whole practice presents them. What we supply is a shell whose storage bones map cleanly onto what the standards describe, with the build documentation your director can put in front of an inspector. Whether the finished base unit passes is between your practice and the College, exactly as it should be.

We would rather say that plainly than learn you assumed otherwise. It is the same line we hold with fire departments buying training props and processors buying cold rooms: we supply the box and the honest fit-out; the licence, the inspection, and the profession stay yours.

Siting, Power, and Delivery

A 20ft base unit needs a parking-spot-sized piece of firm, level ground and a straight approach for the tilt-deck truck. Power is a standard electrician’s connection for lights, climate, and the refrigerator; nothing about a storage base unit needs industrial service. Delivery runs one to three days across the province out of Brantford, and the lead time we give you is the one you get.

If you are still weighing a container against a shed, a trailer, or leased space, the comparison hub that weighs every structure we compete with puts the options side by side. Or do what the practical buyers do: drive to Brantford, walk a converted unit, and picture your shelving in it. Mobile vets are on the road all day anyway, and our buyers keep telling us the yard is worth the drive.

Frequently Asked Questions

What is a base unit for a mobile veterinary practice?

Under Ontario’s veterinary facility accreditation standards, a mobile unit has a stationary element called a base unit: a space for secure storage of equipment, supplies, pharmaceuticals, and medical records. The vehicle sees patients; the base unit anchors the regulated storage side of the practice.

Does a mobile vet in Ontario need a physical location?

Yes. The CVO standards define every mobile practice as having a stationary base unit, and accredited facilities are inspected on a five-year cycle. The base unit can be modest, but it must handle secure drug storage, temperature control, records, and cleanable surfaces properly.

Can a shipping container work as a veterinary base unit?

A fitted container maps closely onto the storage requirements: steel security, a separate locked drug cabinet, insulation with real climate control, lined washable surfaces, and a plumbed sink finished by your licensed plumber. Accreditation itself is assessed by the College, not by any supplier.

Who installs the sink and electrical in a container base unit?

We rough in plumbing and electrical at the yard and document the work; your licensed plumber and electrician make the final connections and certify them on site. That split keeps every regulated connection under the licence that is supposed to hold it.

How big should a mobile vet base unit be?

A 20ft container gives about 13.9 square metres inside, which handles drug storage, inventory, records, and a work counter with room to move. Practices carrying large-animal equipment or bulk feed supplements step up to a 40ft and partition it.
