Natural Health Product Licence vs Cannabis Licence: Key Differences

If you make, import, or sell a health product in Canada, one of the first questions you have to answer is deceptively simple: what is it, and which law governs it? A vitamin capsule, a herbal tincture, a CBD oil, and a dried cannabis flower can all look similar on a shelf, yet they sit under two completely separate federal regimes with different applications, timelines, fees, and inspectors. Choosing the wrong pathway, or assuming one licence covers a product it does not, is one of the most expensive mistakes a new company can make.

A natural health product (NHP) licence and a cannabis licence are not two versions of the same thing. They come from different statutes, are administered by different parts of Health Canada, and carry very different obligations for security, quality, and record keeping. This guide sets out the key differences in plain terms so that founders, regulatory managers, and quality leads can pick the right pathway with confidence and avoid the classification errors that stall a launch.

Executive Summary

Natural health products and cannabis are governed by two separate legal frameworks. NHPs fall under the Food and Drugs Act and the Natural Health Products Regulations, administered by the Natural and Non-prescription Health Products Directorate. To sell an NHP you need a product licence, shown on the label as an eight digit Natural Product Number (NPN) or a DIN-HM for homeopathic medicines. Companies that manufacture, package, label, or import NHPs also need a site licence and must meet good manufacturing practices set out in Part 3 of the Regulations and the guide GUI-0158.

Cannabis is governed by the Cannabis Act and the Cannabis Regulations. There is no single cannabis licence. Instead, Health Canada issues licences by class of activity, such as cultivation, processing, sale for medical purposes, analytical testing, research, and nursery. Cannabis licences layer on requirements that NHPs never face: security clearances for key personnel, physical security measures, good production practices under Part 5, and detailed tracking and reporting. Because cannabis is excluded from the NHP definition, a product that meets the legal definition of cannabis cannot be licensed as an NHP, and a genuine NHP cannot be authorised through the cannabis system. Getting the classification right at the start protects your timeline, your budget, and your licence.

What Is a Natural Health Product Licence?

A natural health product licence is Health Canada's authorisation to sell a specific NHP in Canada. It confirms that the product is safe, effective, and of suitable quality for its stated use. Why it matters: without a product licence you cannot legally sell the product, and the licence number must appear on the label. What to do: classify the product, gather safety and efficacy evidence, and submit a product licence application, then secure a site licence if you manufacture, package, label, or import.

NHPs include vitamins and minerals, herbal remedies, probiotics, amino acids, essential fatty acids, traditional medicines such as traditional Chinese and Ayurvedic preparations, and homeopathic medicines. They are defined and regulated under the Natural Health Products Regulations (SOR/2003-196), made under the Food and Drugs Act. The Natural and Non-prescription Health Products Directorate reviews applications.

Two authorisations matter. The product licence is product specific. When it is granted, Health Canada issues a Natural Product Number, or NPN, that must be displayed on the label. Homeopathic medicines receive a DIN-HM instead. The site licence is company and facility specific. Any business that manufactures, packages, labels, or imports NHPs for sale must hold a site licence and demonstrate that its premises and quality systems meet good manufacturing practices.

Good manufacturing practices for NHPs are set out in Part 3 of the Regulations and interpreted through Health Canada's guide GUI-0158. Version 4.0 of that guide came into force on 4 March 2026, raising the evidentiary bar on stability data, importer oversight, and quality systems. If you hold or plan to hold an NHP site licence, our detailed walkthrough of the GUI-0158 Version 4.0 changes explains what inspectors now expect to see.

What Is a Cannabis Licence?

A cannabis licence is Health Canada's authorisation to conduct a specific cannabis activity, such as growing, processing, testing, or selling cannabis. Why it matters: cannabis is a controlled substance, so activities are illegal without the correct licence, and each licence class permits only defined activities. What to do: decide which activities you will perform, prepare the site and personnel, obtain security clearances, and apply for the matching licence class through Health Canada's licensing system.

Cannabis is regulated under the Cannabis Act (S.C. 2018, c. 16) and the Cannabis Regulations (SOR/2018-144). Unlike NHPs, there is no single product number and no one size fits all licence. Health Canada grants licences by class of activity, and a company often holds more than one.

The main federal licence classes are cultivation (standard, micro, and nursery), processing (standard and micro), sale for medical purposes, analytical testing, and research. Each class permits only certain activities. A micro cultivation licence, for example, caps the plant canopy at 200 square metres, while a standard cultivator has no set upper limit. Retail sale to adults for non-medical use is licensed and run by the provinces and territories, not by Health Canada, which is a further layer that NHPs do not have.

Cannabis licences also require security clearances from Health Canada for directors, officers, and other key personnel, physical security measures appropriate to the activity, good production practices under Part 5 of the Regulations, and a designated Quality Assurance Person who approves product for release. Excise duty and stamping obligations administered by the Canada Revenue Agency add another compliance stream that has no NHP equivalent.

Two Different Legal Frameworks Side by Side

The clearest way to see the difference is to line the two regimes up against each other. The table below compares the core features that most affect how you apply, what you build, and how you stay compliant.

Feature	Natural Health Product	Cannabis
Governing law	Food and Drugs Act and Natural Health Products Regulations (SOR/2003-196)	Cannabis Act (S.C. 2018, c. 16) and Cannabis Regulations (SOR/2018-144)
Health Canada branch	Natural and Non-prescription Health Products Directorate	Controlled Substances and Cannabis Branch
Product authorisation	Product licence with an NPN or DIN-HM on the label	Licence by class of activity, no single product number
Facility authorisation	Site licence for manufacture, package, label, import	Licence tied to the site and activity class
Quality standard	Good manufacturing practices, Part 3 and GUI-0158	Good production practices, Part 5 of the Regulations
Personnel screening	No security clearance required	Health Canada security clearances for key roles
Physical security	General GMP controls	Prescribed physical security measures
Provincial layer	None for federal sale	Provincial and territorial retail authorisation
Other agencies	None routine	Canada Revenue Agency excise duty and stamps

Product Authorisation: NPN Versus Licence Class

The single most visible difference is how a product is authorised. An NHP is approved product by product. You submit a product licence application that names the medicinal ingredients, dose, use or purpose, and supporting evidence. If Health Canada is satisfied, it issues an NPN that stays with that formulation and appears on the label. Change the formulation or the claim and you generally need to amend or resubmit.

Cannabis works differently. Health Canada licenses the activity and the site, not each individual stock keeping unit. Once you hold the right licence class and meet good production practices, you can produce and release products within the categories your licence permits, such as dried cannabis, extracts, edibles, or topicals, subject to the composition and packaging rules in the Regulations. There is no product number stamped on the package the way an NPN is. This makes the cannabis system more flexible at the product level but far more demanding at the facility and personnel level.

Site and Facility Requirements: Site Licence Versus GPP

Both regimes care deeply about how and where a product is made, but they express that concern through different instruments. For NHPs the key instrument is the site licence, backed by good manufacturing practices in Part 3 of the Regulations and GUI-0158. A site licence holder must show controlled premises, qualified personnel, validated processes, real time stability data, sanitation, and records that prove the system works in practice, not just on paper.

For cannabis, the equivalent quality framework is good production practices under Part 5 of the Cannabis Regulations. GPP covers sanitary facilities and equipment, pest control, controlled storage, validated sanitation, qualified staff, and mandatory testing for contaminants and potency before sale. On top of GPP, cannabis sites must meet prescribed physical security requirements, including restricted access, intrusion detection, and video surveillance, that NHP sites are not subject to. If you want a deeper look at how quality expectations converge and differ, our team compares the two standards in day to day practice through our quality assurance services.

Quality Oversight: The Role of the QAP

Both frameworks put a named quality professional at the centre of product release, but the weight of the role differs. Under the NHP GMP framework, a Quality Assurance Person is responsible for the quality of products before they reach the market, with clear written authority to approve, reject, and recall. Version 4.0 of GUI-0158 sharpened this, adding explicit senior management accountability above the QAP.

In the cannabis system, the QAP is a legal requirement written directly into the Regulations. The cannabis QAP must hold a valid Health Canada security clearance, review testing results against specifications, and approve every lot before it is made available for sale. Since the 12 March 2025 streamlining amendments, a processing licence holder may designate one or more alternate QAPs to cover absences while keeping overall accountability. If your operation needs experienced quality oversight, MFLRC provides QAP and quality assurance support across both sectors.

Where the Two Regimes Meet, and Where They Do Not

A common and costly misunderstanding is that a low dose cannabis or CBD product can be sold as a natural health product. It cannot. Cannabis is deliberately excluded from the definition of a natural health product, so any product that meets the legal definition of cannabis, including most CBD derived from the cannabis plant, is regulated under the Cannabis Act rather than the NHP Regulations, regardless of how low the THC content is.

Health Canada consulted on a possible pathway for cannabis health products that could be sold without a prescription, and separately reviewed a proposal to allow certain CBD products through a health product route. As of mid 2026 neither has become a live commercial pathway, so the practical position is unchanged: sell cannabis under a cannabis licence, and sell genuine NHPs under an NHP licence. Prescription cannabis drugs, by contrast, go through the pharmaceutical drug review pathway, not the NHP route.

Timelines, Cost, and Ongoing Obligations

The two pathways also differ in how long they take and what they cost to maintain. NHP product licence timelines depend on the application class, from faster reviews for well known ingredients to longer reviews for products that need full safety and efficacy assessment. Site licences are issued once the facility and quality systems are assessed. Cannabis licensing is generally longer and more resource intensive because of the security, facility, and personnel requirements, and it adds recurring obligations such as regulatory fees, excise, and frequent inspection.

Obligation	Natural Health Product	Cannabis
Primary application	Product licence application to NNHPD	Licence application by activity class to Health Canada
On-label identifier	NPN or DIN-HM	No product number; licence held by the operator
Facility approval	Site licence	Licensed site, pre-licence inspection common
Personnel screening	Not required	Security clearances before licence issued
Ongoing quality	GMP per Part 3 and GUI-0158	GPP per Part 5, testing every lot
Inspections	Risk based site inspections	Risk based, many unannounced; 889 activities in FY 2024 to 2025
Tax and duty	Standard business tax	CRA excise duty and stamps

Cannabis inspection activity is significant and rising. In fiscal year 2024 to 2025, Health Canada carried out 889 inspection activities and issued 37 non-compliant reports, up from 21 the year before, according to its compliance and enforcement report. NHP inspections are also intensifying under GUI-0158 Version 4.0. Whichever pathway you choose, ongoing readiness matters as much as the initial licence.

Classification and Licensing Checklist

Before you commit to an application, work through the following checks to confirm you are on the right pathway and prepared for review.

Confirm the legal classification of the product, NHP or cannabis, before spending on any application.
For an NHP, identify the medicinal ingredients and match them to Health Canada monographs or assemble the required safety and efficacy evidence.
Determine whether you need a site licence, which applies to manufacturing, packaging, labelling, and importing NHPs.
For cannabis, list every activity you will perform and map each to the correct licence class.
Start security clearance applications early for cannabis directors, officers, and key personnel, since these can gate the whole timeline.
Build the correct quality system: GMP under Part 3 and GUI-0158 for NHPs, or GPP under Part 5 for cannabis.
Designate a qualified Quality Assurance Person and, for cannabis, at least one alternate.
Confirm provincial or territorial retail authorisation if you plan to sell cannabis to consumers.
Plan for ongoing obligations: stability, testing, records, inspections, and, for cannabis, excise.

Common Mistakes to Avoid

Assuming a CBD or low THC product can be sold as an NHP. If it is legally cannabis, it needs a cannabis licence.
Applying for a single cannabis licence and expecting it to cover every activity. Each activity needs the right class.
Underestimating cannabis security clearance timelines and starting them too late.
Treating an NHP site licence as a formality. Under GUI-0158 Version 4.0, inspectors expect evidenced stability and importer oversight.
Making a therapeutic claim on a cannabis product. Health promotion of cannabis is tightly restricted under the Cannabis Act.
Changing an NHP formulation or claim without amending the product licence.
Forgetting the provincial retail layer for consumer cannabis sales.

Frequently Asked Questions

Can one licence cover both NHPs and cannabis?

No. The two products are regulated under separate laws and separate parts of Health Canada. An NHP product licence and site licence authorise natural health products only, while a cannabis licence authorises defined cannabis activities only. A company that handles both needs authorisations under each framework.

Is CBD a natural health product in Canada?

Generally no. CBD derived from the cannabis plant meets the legal definition of cannabis and is regulated under the Cannabis Act, not the NHP Regulations, regardless of how low the THC content is. Health Canada has consulted on possible health product pathways for CBD, but as of mid 2026 there is no live commercial route to sell CBD as a standard NHP.

What is an NPN and where does it appear?

An NPN is the eight digit Natural Product Number that Health Canada assigns to a licensed natural health product. It must appear on the product label and confirms that the product has been assessed and authorised for sale. Homeopathic medicines carry a DIN-HM instead.

Do NHP companies need a security clearance like cannabis companies?

No. Security clearances for directors, officers, and key personnel are a cannabis specific requirement under the Cannabis Regulations. NHP site licence holders must meet good manufacturing practices, but there is no equivalent personnel security clearance regime.

Which pathway takes longer to license?

Cannabis licensing is generally longer and more resource intensive because it adds security clearances, physical security, and facility readiness on top of quality systems. NHP timelines vary by application class and are often shorter for products that use well established ingredients, though a site licence still requires a facility and quality assessment.

Are NHP and cannabis facilities inspected the same way?

Both use risk based inspection, but the details differ. Cannabis sites face frequent inspection, many of them unannounced, against good production practices and security requirements. NHP sites are inspected against good manufacturing practices, and expectations rose sharply when GUI-0158 Version 4.0 came into force in March 2026.

Conclusion

Natural health product and cannabis licences are two separate systems, not two flavours of the same one. NHPs run on product licences, NPNs, site licences, and GMP under GUI-0158. Cannabis runs on class based activity licences, security clearances, physical security, and GPP under Part 5, with a provincial retail layer and excise on top. The single most important decision is the first one: classify the product correctly, because everything downstream follows from it. Get that right and the rest of the pathway becomes far more predictable. For related reading, see our guides on how often cannabis companies get audited and how effective the NHP Regulations are.
