What security does cannabis transport require?

Security for cannabis in transit isn’t defined by a single checklist you can look up — it’s defined by the licence holders whose product is on the truck. Producers, the OCS and authorized retailers carry regulatory obligations for their inventory, and they pass those obligations to carriers through contracts and operating procedures. In practice, the expectations converge on four things: sealed shipments, direct routing, documented custody and disciplined incident reporting. This page explains each one, plainly — it describes common practice, not legal advice.

It helps to picture the requirements as three layers. The federal framework places security obligations on licence holders; each licence holder translates its obligations into contractual terms for the carriers it hires; and the carrier turns those terms into standard operating procedure for drivers and dispatch. By the time a truck rolls, “security” is a set of concrete habits — and the four below are the ones that appear in virtually every regulated shipper’s expectations.

Sealed shipments: the load is closed at origin and opened at destination

The baseline expectation is that cannabis freight travels sealed. The shipper closes and seals the load — sealed cartons, sealed totes, or a sealed cargo area — before the vehicle leaves, and the seal stays intact until the authorized receiver breaks it. Between those two points, nobody opens the freight, including the driver.

Seals do two jobs. They deter interference, and more importantly they prove the absence of interference: an intact seal at delivery is documented evidence that what left the licensed site is what arrived. Seal numbers are typically recorded on the shipping paperwork at origin and verified at destination, which folds the seal into the chain of custody rather than leaving it as a loose detail. A seal that arrives mismatched or broken is treated as an event in its own right — the receiver stops, the shipper is notified, and nothing is signed for casually.

Direct routing: the freight goes where it’s going

Cannabis loads are expected to move directly from origin to destination — no detours, no overnight layovers in unsecured yards, no unrelated stops with regulated product aboard. Where a run has multiple legitimate drops, the route is planned and known in advance rather than improvised.

Direct routing is why dedicated vehicle service fits regulated freight naturally: one truck, one shipper’s freight, a planned route and no co-mingling with other customers’ goods. It shrinks the number of variables between pickup and delivery, which is precisely what a licence holder’s security posture wants.

Documented custody: every handoff has a name, a time and a signature

At every point where responsibility for the freight changes hands, the transfer is recorded — who released it, who took it, when, and in what condition. On the road that means:

• Pickup: the driver signs for the shipment against the shipping document, and seal numbers are noted.
• In transit: the freight stays with the assigned vehicle and driver; there are no informal transfers.
• Delivery: the authorized receiver verifies the seal and piece count, then signs the proof of delivery.

The paper trail is the security system’s memory. If a question ever arises about a shipment, the custody records answer it — which is why documentation expectations sit alongside physical measures rather than beneath them. What those records typically include is covered in detail in what records cannabis shipments require.

People and vehicles: screening, discipline, discretion

Carriers handling regulated freight typically apply their own personnel and vehicle practices on top of the contractual requirements:

• Consistent, known drivers on regulated runs, rather than rotating unfamiliar staff through them — shippers often want to know who is carrying their freight. Driver-side questions, including the common misconception about special licences, are addressed in do drivers need a licence to carry cannabis.
• Locked cargo areas whenever the vehicle is unattended, even briefly.
• Unmarked freight — nothing on the vehicle or packaging that advertises the contents.
• Communication discipline: the driver, dispatcher and shipper know the plan, and deviations get flagged in real time rather than explained afterward.

None of this is exotic. It’s the same discipline good carriers apply to any high-value B2B freight, applied consistently and documented thoroughly. Our guide to choosing a carrier for regulated freight turns these practices into a vetting checklist.

Incident reporting: problems surface immediately

The final expectation is about what happens when something goes wrong — a seal discrepancy, a delay, a vehicle problem, or anything worse. The operational standard is immediate notification to the shipper, honest documentation of what happened, and full cooperation with whatever follows. Licence holders carry their own reporting obligations to regulators, and they can only meet them if their carrier surfaces problems at once rather than at the end of the day.

A note on verification: security expectations in this space are set by contract and by regulatory obligations that can change. Before building an operating procedure around any summary — including this one — verify current requirements with Health Canada, the AGCO and the OCS, and with the compliance teams of the licence holders you serve. The broader regulatory picture is laid out in our Ontario cannabis freight guide.
