Cannabis Micro Licence in Canada: Cultivation and Processing Guide

Canada's micro-class cannabis licences were created to give small and craft producers a realistic way into a tightly regulated market. For several years, the size limits were modest. That changed in 2025. Health Canada quadrupled the production thresholds for micro-cultivation, micro-processing and nursery licences, opening real room to grow before stepping up to a standard licence.

This guide explains what each micro licence now allows, the current grow surface area and possession limits, how the application works through Health Canada's Cannabis Tracking and Licensing System (CTLS), and the compliance obligations that follow once you are licensed. The figures here reflect the Cannabis Regulations as amended by SOR/2025-43, which came into force on 12 March 2025.

Executive summary

If you are weighing a small-scale entry into Canada's legal cannabis sector, the micro-class route is more attractive than it was a few years ago. Here is the short version.

Three micro-class licences exist: micro-cultivation, micro-processing and nursery.
SOR/2025-43 increased the micro and nursery limits fourfold as of 12 March 2025.
All applications run through the CTLS and require security-cleared key personnel.
Good Production Practices (GPP) and a Quality Assurance Person (QAP) are mandatory.
A federal licence does not let you sell to the public. Provincial or territorial authorization and excise registration with the Canada Revenue Agency are separate steps.

What is a cannabis micro licence?

A cannabis micro licence is a federal authorization issued by Health Canada under the Cannabis Act and Cannabis Regulations. It lets small-scale operators cultivate or process cannabis within set size and quantity limits. It matters because it offers a lower-barrier entry point than a standard licence, with the same quality and security expectations. The practical message is simple: treat a micro licence as a full regulated licence, not a relaxed one.

There are three micro-class options. Micro-cultivation is for growing. Micro-processing is for making products such as oils, edibles, extracts and topicals. A nursery licence is for producing starting material, the plants, seeds and pollen that feed the rest of the supply chain. Many operators hold more than one of these at a single site.

Licence type	Current limit	What you can produce	Who you can sell to
Micro-cultivation	Up to 800 m2 grow surface area (plant canopy)	Cannabis plants, seeds, pollen, fresh and dried cannabis	Other federal licence holders
Micro-processing	Up to 2,400 kg dried cannabis or equivalent per calendar year	All cannabis product types, except by cultivating, propagating, harvesting or synthesizing	Other licence holders and provincially authorized distributors
Nursery	Up to 200 m2 flowering/budding canopy; up to 20 kg harvested flowering heads at any time	Starting material: plants, seeds and pollen	Other licence holders and authorized parties

Micro-cultivation licence: the 800 m2 rule

A micro-cultivation licence allows you to grow cannabis using a grow surface area of up to 800 m2. Why it matters: that is four times the old 200 m2 limit, so a craft grower can now reach meaningful volume without a standard licence. What to do: calculate your canopy correctly, because Health Canada measures the plant surface area, not the size of the room.

The grow surface area includes all horizontally and vertically arranged surfaces, both indoor and outdoor, that are in use at any single time. It must capture every part of the plant, including overhanging leaves and branches. There is no limit on plant height. Areas used only for storage, packaging and labelling, and the walkways between grow tables, do not count. If you use different areas across seasons, you calculate the total for each period so you never exceed 800 m2 at any given moment.

Micro-processing licence: the 2,400 kg limit

A micro-processing licence lets you make cannabis products while holding up to 2,400 kg of dried cannabis, or its equivalent, in a calendar year. Why it matters: the limit counts inventory carried over from the previous year, so poor planning can put you offside. What to do: track equivalency carefully using the regulatory equivalency table, especially when you handle extracts and concentrates.

A micro-processor can produce all types of cannabis except by cultivating, propagating, harvesting or synthesizing it. There is an important exception to the possession limit. If you hold both a micro-cultivation and a micro-processing licence at the same site, and you only process cannabis grown under your own cultivation licence, the 2,400 kg limit does not apply. The moment you bring in cannabis from another licence holder, the limit applies to your total holdings. Plants and seeds never count toward the possession limit.

Nursery licence: producing starting material

A nursery licence authorizes production of cannabis starting material, meaning plants, seeds and pollen, with up to 200 m2 of flowering or budding canopy and no more than 20 kg of harvested flowering heads at any time. Why it matters: nurseries supply genetics and clones to the wider industry. What to do: destroy flowering heads, leaves and branches within 30 days of harvest, and keep clear records of it.

Only the flowering and budding canopy counts toward the 200 m2 limit. Areas used to grow vegetative mother plants, cuttings and non-flowering clones are not limited, and neither are storage and non-cultivation areas. This makes a nursery a focused, lower-volume operation that still demands the same quality discipline as any other licence.

Security clearance and key personnel

Health Canada requires named individuals tied to a cannabis licence to hold a valid security clearance. Why it matters: an incomplete or inaccurate clearance application is one of the most common causes of delay, and delays cost money before you earn a dollar. What to do: submit full, accurate histories for every required person, the first time.

Clearances typically cover the responsible person, the head of security, the master grower (for cultivation), the Quality Assurance Person, and directors, officers and key investors who exercise direct control over the applicant. Each person discloses employment, education, travel and any prior charges. Inconsistent or missing information triggers requests for clarification and stalls the file.

Good Production Practices and the QAP

Every micro licence holder must meet Good Production Practices (GPP) and appoint a Quality Assurance Person (QAP). Why it matters: the QAP approves product for release and owns your quality system. What to do: build GPP-compliant standard operating procedures and records before you operate, not after your first inspection.

GPP covers sanitation, pest control, equipment, recall procedures, documentation and analytical testing. The QAP investigates deviations, signs off on batches and ensures records are accurate and complete. A weak quality system is a frequent inspection finding, so investing early in a disciplined QA program pays off when Health Canada visits.

The application process through CTLS

Applications are submitted through Health Canada's Cannabis Tracking and Licensing System (CTLS). Why it matters: a fully built, compliant site and a complete application move faster than a paper promise. What to do: prepare the site and the people before you submit. The core steps are below.

Confirm eligibility and Canadian business or legal standing.
Build a fully constructed site that meets physical security and GPP requirements.
Name and submit security clearance applications for all key personnel.
Prepare the site evidence package: floor plans, security details and grow surface area or possession calculations.
Submit the application and the application-screening fee in the CTLS.
Respond promptly to Health Canada's review, which may include a video or on-site review of your site.

After licensing: excise, provincial sales and reporting

A Health Canada licence authorizes production, not retail sale. Why it matters: you also need to register for cannabis excise duty with the Canada Revenue Agency and secure provincial or territorial authorization to reach consumers. What to do: plan these parallel approvals early so they do not become a bottleneck.

If you package and stamp cannabis products, you generally need a cannabis licence from the CRA under the Excise Act, 2001, and you apply provincial excise stamps. You also report inventory and activity to Health Canada through the CTLS and keep detailed seed-to-sale records. Selling to the public means working through each province or territory's distribution and retail system, which has its own rules and timelines.

Scaling up to a standard licence

Micro and nursery licences can start small and scale up later to a standard cultivation or processing licence, which removes the grow area or possession limit. Why it matters: you do not have to lock yourself into micro volumes forever. What to do: choose the right method and budget for a new screening fee.

If your micro application is still in review, you can move to a standard application using either the transfer method or the withdraw method. Either way, you pay another application-screening fee for the standard application, and the original screening fee is not refunded or transferred. Once you already hold a micro licence, you can apply to change the licence class or subclass through CTLS. The transfer method usually preserves security clearance work, so it is often the cleaner path.

Micro licence compliance checklist

Confirm which micro licence fits your business model and target volume.
Verify your grow surface area or possession calculation against the current limits.
Secure a compliant, fully built site before you apply.
Submit complete, accurate security clearance applications for every key person.
Appoint a QAP and document GPP-compliant SOPs and records.
Implement seed-to-sale tracking and recordkeeping from day one.
Register for cannabis excise duty with the CRA and obtain provincial or territorial authorization to sell.
Run internal audits and a mock recall before your first Health Canada inspection.

Common mistakes to avoid

Miscalculating grow surface area by counting the room and forgetting vertical shelving and overhanging branches.
Treating a micro licence as lighter compliance. The quality and security bar is the same as a standard licence.
Submitting incomplete security clearance disclosures, which stalls the whole application.
Applying before the site is built and ready for review.
Forgetting the excise and provincial steps, then being unable to legally sell after licensing.

Frequently asked questions

How big can a micro-cultivation grow area be in Canada?

Up to 800 m2 of grow surface area (plant canopy), measured across all surfaces in use at any single time, indoor and outdoor. This limit took effect on 12 March 2025 and replaced the previous 200 m2 limit.

How much cannabis can a micro-processor hold?

Up to 2,400 kg of dried cannabis, or its equivalent, in a calendar year. Inventory carried over from the previous year counts toward that limit. Plants and seeds do not count.

Can I hold both a micro-cultivation and a micro-processing licence at one site?

Yes. If you only process cannabis grown under your own micro-cultivation licence at the same site, the 2,400 kg possession limit does not apply. It applies once you also receive cannabis from other licence holders.

How long does it take to get a micro licence?

Timelines vary and commonly run several months. The biggest factors are a fully built compliant site, complete security clearance applications and a clean site evidence package. Incomplete files are the most common reason for delay.

Do I need a Quality Assurance Person for a micro licence?

Yes. A QAP is required and is responsible for approving product release, investigating deviations and maintaining your quality system to Good Production Practices.

Does a micro licence let me sell to the public?

No. A Health Canada micro licence covers production. To reach consumers you need provincial or territorial authorization through the relevant distribution and retail system, plus excise registration with the CRA.
