Canadian Licensed Producers shipped 17,067 kg of dried cannabis flower directly to the UK in 2025. That's more than six times the 2,578 kg recorded a year earlier, according to Home Office import data obtained by Prohibition Partners. Canada now supplies an estimated 70 to 80 percent of the British medical cannabis market, and it accounted for 96 percent of the market's import growth last year.
Exporting cannabis from Canada to the UK requires three approvals. You need a Health Canada export permit for each shipment under the Cannabis Act. Your UK partner needs a Home Office import licence for the consignment, plus an MHRA licence to receive it. Flower enters Britain as an unlicensed medicine known as a special, and that status shapes everything downstream.
If you're a Canadian LP weighing the UK against Germany or Australia, the mechanics differ in a few important ways. Here's how the British framework works in 2026, what your UK partner must hold, and what buyers actually check before they sign a supply agreement.
Why the UK became Canada's fastest-growing cannabis export market
Direct Canadian shipments to the UK grew 562 percent from 2024 to 2025. Total UK flower imports reached roughly 30 tonnes. The quarterly numbers show real acceleration: 5,285 kg arrived in Q1 2025 and 11,810 kg in Q4, a 123 percent jump within the year.
The growth reflects a structural shift, not just bigger demand. UK buyers used to source Canadian-origin flower through European processors, mainly in Spain, which repackaged product before onward shipment. That intermediary model is collapsing. Spain held 51 percent of UK supply in 2023 and just 11.4 percent by 2025, as British importers moved to buying directly from Canadian producers. Analysts at Prohibition Partners describe the change as a move from clinic-led ordering toward wholesale procurement cycles, with importers building inventory quarters in advance.
The large Canadian LPs have noticed. Aurora Cannabis acquired a licensed UK importer and a pharmacy in August 2026 to control its own distribution channel. Tilray raised global cultivation capacity to roughly 275 tonnes the same month, citing international medical demand. For mid-size producers, that consolidation is a signal: competing in the UK on volume alone is getting harder, while consistent quality and clean documentation remain open ground.
How the UK regulates imported cannabis flower
Medical cannabis has been legal in the UK since November 2018, but the framework looks nothing like Canada's. Cannabis remains a controlled drug under the Misuse of Drugs Act 1971. Cannabis-based products for medicinal use, known as CBPMs, were moved to Schedule 2 of the Misuse of Drugs Regulations, which makes licensed handling, prescribing, and import possible.
Here's the part that surprises many Canadian exporters: almost all imported flower is an unlicensed special under the Human Medicines Regulations 2012. No cannabis flower holds a UK marketing authorisation. Each product is supplied against a prescription written by a specialist doctor for a named patient's clinical need. MHRA guidance is explicit that the special need can't be cost or convenience.
In practice, that pushes nearly all volume through private clinics and specialist pharmacies rather than the National Health Service. Demand is prescription-led, but procurement has become wholesale-scale since importers were permitted to hold bulk stock. For an exporter, the customer isn't a government tender board. It's a licensed commercial importer making quarterly buying decisions.
The licence chain your UK partner must hold
Your Health Canada export permit is only half the paperwork. Every consignment also depends on a chain of British approvals held by the importer, and the two sides must match. The table below summarises the UK side for flower shipped from Canada, a non-EEA country.
| Approval | Issued by | What it covers |
|---|---|---|
| Manufacturer's (Specials) Licence | MHRA | Importing unlicensed medicines from non-EEA countries such as Canada |
| Import notification | MHRA | Notice at least 28 days before each intended import, listing product, constituents, quantity, and manufacturer |
| Domestic controlled drug licence | Home Office | Lawful possession and supply of cannabis at the importer's site |
| Import licence | Home Office | Issued per shipment, typically valid for about three months |
Since March 2020, UK importers have been allowed to bring in stock ahead of prescriptions. That single change is why consignment sizes jumped from courier boxes to pallet-scale wholesale orders.
On the Canadian side, you apply to Health Canada for an export permit for each shipment, referencing the UK import licence. The sequencing matters: your partner secures the Home Office import licence first, and your permit application mirrors its product description, quantity, and validity window. We've covered the Canadian half in detail in our guides to the Health Canada export permit process and the two-permit chain behind every cannabis export.
What UK buyers check before signing with a Canadian LP
British Specials importers carry the regulatory risk of every product they bring in, so their diligence is document-heavy. Before commercial terms are discussed, expect a UK buyer to ask for:
- GMP evidence they can defend to the MHRA, typically EU-GMP certification or documentation aligned to a recognised equivalent
- Certificates of analysis from an ISO/IEC 17025 accredited lab covering potency, microbials, heavy metals, and pesticides
- Your irradiation status, stated upfront, since UK clinics increasingly market non-irradiated flower as a premium tier
- Water activity and moisture specifications that will survive an Atlantic crossing and UK warehousing
- Drying, curing, and packaging standards that match the import licence exactly and hold up in UK warehousing
Beyond the file, UK buyers weight two commercial factors heavily. The first is batch-to-batch consistency. A cultivar that tests at 30 percent THC in one shipment and 24 percent in the next creates prescription problems for pharmacy clients. The second is supply reliability across quarterly procurement cycles, because a stock-out forces patients onto a competitor's product and they rarely come back.
AlphaLeaf is a Montreal-based Health Canada Licensed Producer of indoor-grown, hand-trimmed cannabis flower. We hold export authorisation under the Cannabis Act. Our ISO 17025-tested batch data, full traceability records, and EU-GMP-aligned documentation give UK Specials importers the evidence file their MHRA and Home Office licences depend on.

Frequently Asked Questions
Is medical cannabis legal in the UK in 2026?
Yes. Medical cannabis has been legal on specialist prescription since November 2018. Nearly all cannabis flower is supplied as an unlicensed special through private clinics and specialist pharmacies, because no flower product holds a UK marketing authorisation.
What licences does a UK importer need for Canadian cannabis flower?
Three approvals: an MHRA Manufacturer's (Specials) Licence covering non-EEA imports, a Home Office domestic controlled drug licence, and a per-shipment Home Office import licence. The importer must also notify the MHRA at least 28 days before each intended import.
How much cannabis does the UK import from Canada?
Canadian producers shipped 17,067 kg of dried flower directly to the UK in 2025, up from 2,578 kg in 2024, per Home Office data. Canada supplied an estimated 70 to 80 percent of the UK medical cannabis market that year.
Does Canadian cannabis need EU-GMP certification for the UK?
UK Specials importers must source from manufacturers whose quality standards they can evidence to the MHRA. In practice, most UK buyers ask Canadian LPs for EU-GMP certification or documentation aligned to a recognised equivalent, alongside ISO/IEC 17025 accredited certificates of analysis.
How long does a UK cannabis import licence take?
Home Office import licences are issued per shipment and are typically valid for about three months. Processing historically took several weeks. Since March 2020, importers have been permitted to bring in bulk stock ahead of prescriptions, which shortened the wait between prescription and dispensing.
