Health Canada listed 903 current federal cannabis licences as of March 9, 2026, and 102 new licences were issued in 2025 alone. Most of those new licences belong to micro-cultivators and brand-led processors who don't grow everything they sell. They buy it. Wholesale cannabis in Canada is the licence-holder-to-licence-holder trade that keeps those shelves stocked, and it runs on rules that are different from both the export market and the retail market.
Wholesale cannabis sales in Canada are bulk transfers of dried flower between federal licence holders under the Cannabis Regulations. The seller needs a cultivation or processing licence that authorises sale, and the buyer needs a licence that permits it to receive that cannabis. Each lot ships unpackaged, unstamped and free of excise duty until someone packages it for the consumer market. Sign-off on the finished product comes from the buyer's quality assurance person rather than the seller's. This guide walks through who can sell to whom, how the excise rules work, what a buying LP checks before a lot ships, and where these deals stall.
Who can sell wholesale cannabis to whom under the Cannabis Regulations
Section 11(5) of the Cannabis Regulations sets the rules for cultivators. A holder of a standard or micro-cultivation licence whose licence authorises sale may sell dried cannabis, fresh cannabis, plants and seeds to:
- Another holder of a micro-cultivation or standard cultivation licence
- A holder of a licence for processing
- A holder of a licence for analytical testing
- A holder of a licence for research
- A holder of a cannabis drug licence
Provincial and territorial distributors are not on that list. A cultivator cannot sell finished product to the Ontario Cannabis Store or the SQDC directly. Packaging, labelling and sale to a province are processing-licence activities, which is why nearly every bulk flower deal in Canada ends with a processor on the buying side. The processor packages the flower under its own brand, affixes its own excise stamps and ships to the provincial wholesaler.
The buyer's licence matters as much as the seller's. A micro-processor is capped on the quantity of dried cannabis it can process each year. A bulk offer larger than that allowance is useless to it at any price. Ask for the licence number and the licence class before you quote volume. Health Canada publishes the licence list, and a two-minute check saves a month of negotiating with the wrong counterparty.
One more constraint comes from the Cannabis Act itself: both sites must hold a valid licence on the day the cannabis moves. If the buyer's licence lapses mid-contract, the seller holding a signed purchase order still cannot ship. Build a licence-status warranty into the contract, because Health Canada revoked 90 commercial licences in 2025 and the counterparty you signed with in January may not exist in June.
Excise duty on bulk flower: who pays and when
The Excise Act, 2001 makes cannabis duty payable by the cannabis licensee that packaged the product, at the time that packaged product is delivered to a purchaser. Unpackaged flower moving between two cannabis licensees doesn't trigger duty. The grower sells bulk, the processor packages and stamps, and the processor owes the Canada Revenue Agency when the stamped product leaves its premises.
Three details trip up first-time wholesale buyers:
Both parties need a CRA cannabis licence
A Health Canada cultivation or processing licence is not an excise licence. The CRA issues the cannabis licence under the Excise Act, 2001, and a cultivator that sells bulk flower still needs one to possess and transfer unpackaged cannabis. In 2024, StratCann reported Health Canada data showing that only 322 of 808 cannabis excise licence holders were active and remitting duty as of September 2023. Plenty of licensed sites sit dormant on the excise side. Confirm the buyer's excise licence is active rather than merely issued.
Packaged-but-unstamped product cannot just change hands
CRA Excise Duty Notice EDN84, published in January 2023, allows two licensees to move unstamped packaged product or excise stamps between them. The catch is that the CRA must approve a service agreement in advance. The application needs at least 60 days. If your deal involves the seller doing the packaging and the buyer applying its own stamps, that paperwork has to be in place before the first lot moves. Bulk flower sold unpackaged avoids all of this, which is one reason most Canadian wholesale deals stay in bulk.
Export is the exception
Flower that leaves Canada under an export permit is relieved of duty. The excise maths for a Montreal LP shipping to Germany look nothing like the maths for the same LP selling to a brand in Toronto. Our guide to cannabis excise duty and exports for Canadian LPs covers the export side. The domestic side is simpler in structure but easier to get wrong, because the duty becomes the buyer's liability the moment it packages your flower.
The practical consequence: a wholesale price is quoted before duty, before provincial markup and before retail margin. Compare quotes on that basis, and read our breakdown of what drives bulk flower pricing per gram in 2026 before you anchor on a number.
What a buying LP checks before a bulk flower lot ships
Part 5 of the Cannabis Regulations sets out Good Production Practices. Under it, every lot of dried cannabis must be approved by the licence holder's quality assurance person before it's sold. The seller's QAP releases the bulk lot. The buyer's QAP releases the packaged product. Two sign-offs, two sets of records, and the buyer inherits every weakness in the seller's file.
A competent buying QAP asks for the following before the lot leaves the seller's vault:
- A certificate of analysis from a Health Canada-licensed analytical testing lab, ideally accredited to ISO/IEC 17025, covering cannabinoid potency, microbial load, heavy metals and mycotoxins
- Pesticide results against Health Canada's mandatory testing list, which has been in force since January 2, 2019 and runs to 96 active ingredients
- Moisture content or water activity, with the test date, so the buyer knows how the lot was stored since harvest
- The lot number, harvest date, cultivar name and plant count linked to that lot in the seller's tracking system
- A visual sample from the same lot, not a showcase jar from a different harvest
Terpene data isn't a regulatory requirement for domestic sale, yet most brands now ask for it because terpene content decides whether the flower can carry a premium SKU. If you want to interpret that COA line by line, our guide on how to read a cannabis COA walks through every panel.
Trim quality is the other inspection point. Machine-trimmed flower loses trichome coverage and bud structure, and a brand selling 3.5 g premium jars will reject it on sight. The difference is covered in our comparison of hand-trimmed versus machine-trimmed cannabis. Buyers paying premium prices should ask how the lot was trimmed and insist on seeing it in person. A photograph proves nothing.
Moisture is where cheap flower hides its cost. A lot that reads 14% moisture at the seller's dock and 10% at the buyer's intake has lost 4% of its sellable weight in transit, and the invoice didn't shrink with it. Agree on a reference method and a reading at both ends, and read our note on water activity and moisture limits before you write that clause. Weight loss between dock and intake is the most common cause of invoice disputes in domestic bulk deals, and it's entirely avoidable.
Where LP-to-LP deals stall, and how the contract should handle it
The Cannabis Regulations were made in June 2018 and came into force on October 17, 2018. The first bulk flower deals between licence holders closed within months. Eight years later the paperwork is mature, but the same five problems keep surfacing. Name them in the supply agreement and most of them disappear.
1. Lot size and cadence don't match the buyer's listing calendar
Provincial wholesalers run product calls on a schedule, and a brand that misses a listing window holds inventory for a quarter. Agree on delivery dates tied to the buyer's launch plan rather than the grower's harvest convenience. A grower who harvests in 8-week cycles can commit to a monthly cadence. One who harvests twice a year cannot, and shouldn't pretend to.
2. The sample approved doesn't match the lot delivered
Write sample approval into the contract as a condition of shipment, with the sample pulled from the specific lot being sold. Then define the rejection standard in numbers: potency within a stated range of the COA, moisture within a stated band, foreign matter at zero. Vague "commercially acceptable quality" language is how disputes start.
3. Traceability records don't transfer cleanly
Both parties report inventory movements to Health Canada every month through the Cannabis Tracking and Licensing System, and the two reports have to agree. A lot the seller logs as shipped on the 30th and the buyer logs as received on the 2nd shows up as a discrepancy across two reporting periods. Our walkthrough of CTLS monthly reporting for Canadian LPs explains the timing, and our guide to batch traceability for B2B buyers covers what the receiving records should contain.
4. Payment terms assume the buyer has cash it doesn't
Processors pay the excise duty, the provincial markup and the packaging bill before they see a dollar from the province. Provincial payment often lands 30 to 60 days after delivery. A grower offering net-30 on a bulk lot is financing the brand's working capital. Price that in, or shorten terms with a deposit. Our review of supply agreement terms for Canadian LPs sets out the clauses that protect the seller.
5. Nobody visited the grow
A brand that buys bulk flower on price alone, without walking the cultivation rooms, is buying a recall it hasn't been notified of yet. Site visits cost a day. Recalls cost the brand. Pesticide contamination, mould from poor drying and mislabelled cultivars all show up in the rooms before they show up on a COA, and a supplier who won't host a visit is telling you something.
AlphaLeaf is a Health Canada Licensed Producer based in Montreal, cultivating indoor, hand-trimmed flower from refined genetics for the B2B market. Every lot is tested by an ISO/IEC 17025-accredited lab and carries full batch traceability from clone to vault. Our quality assurance person releases it before it's offered to Canadian processors or to our export partners under our Cannabis Act export authorisation. Our Ice Cream Cake, a Wedding Cake x Gelato cross testing at 30.3% THC in a large-bud format over 5 cm, was built for brands that need a flagship SKU to hold its spec lot after lot.
The domestic wholesale market rewards growers who can document everything and brands who check it. Read about how AlphaLeaf grows, trims and releases every lot, or contact our business development team to request a COA and a sample from current inventory. The flower is ready. Paperwork is done.

Frequently Asked Questions
Can a licensed cultivator in Canada sell dried cannabis directly to a provincial distributor?
No. Under section 11(5) of the Cannabis Regulations, a standard or micro-cultivation licence holder may sell dried cannabis only to other cultivation licence holders, processing licence holders, analytical testing and research licence holders, and cannabis drug licence holders. Sale to a provincial or territorial distributor requires a processing licence, which authorises packaging and labelling of cannabis products.
Is excise duty charged on bulk cannabis sold between two licence holders?
Not at the point of the bulk sale. Under the Excise Act, 2001, cannabis duty is payable by the licensee that packages the product, at the time the packaged and stamped product is delivered to a purchaser. Unpackaged flower transferred between two CRA cannabis licensees does not trigger duty. The processor that packages and stamps the flower pays the duty when it ships to the provincial wholesaler.
What documents should a buyer request before a wholesale cannabis lot ships?
Request a certificate of analysis from a licensed analytical testing lab covering potency, microbials, heavy metals and mycotoxins, plus pesticide results against Health Canada's mandatory list of 96 active ingredients. Add a moisture or water activity reading with the test date, the lot number, harvest date and cultivar, and a physical sample pulled from the same lot. The buyer's quality assurance person uses these to release the packaged product.
Do both the seller and the buyer need a CRA cannabis licence for a bulk sale?
Yes. The Health Canada licence under the Cannabis Act does not replace the cannabis licence issued by the Canada Revenue Agency under the Excise Act, 2001. Any cultivator or processor that possesses or transfers unpackaged cannabis products needs an active CRA cannabis licence. Buyers should confirm the counterparty's excise licence is active rather than merely issued.
What is a CRA service agreement under EDN84 and when is it needed?
Excise Duty Notice EDN84, published by the CRA in January 2023, lets two cannabis licensees move unstamped packaged product or excise stamps between them. A typical case is one licensee packaging on behalf of another. The agreement must be approved by the CRA in advance, with the application submitted at least 60 days before activities begin. Bulk unpackaged flower sold outright does not need a service agreement.
How does CTLS reporting work when flower moves between two licence holders?
Both the seller and the buyer report the movement in their monthly Cannabis Tracking and Licensing System submissions to Health Canada. The seller records the lot as sold and shipped, and the buyer records it as received. Dates and quantities should match. A shipment logged at month-end by one party and at the start of the next month by the other will show up as a discrepancy across two reporting periods.
