Vegan Chocolate That Contained Milk: What Health Canada's Edible Cannabis Recall Reveals About Your QA Programme

Health Canada's inspectors recently pulled five edible cannabis products from shelves in Ontario and Saskatchewan. The chocolates were branded vegan, yet laboratory testing found undeclared milk and hazelnut. The cannabinoid numbers were wrong too, sometimes badly: one product carried more than three times the tetrahydrocannabinol (THC) printed on its label. The products had been on sale for fourteen months before anyone caught the problem, and the person who caught it was a Health Canada inspector, not the licence holder's own quality team.

For any licensed processor of edible cannabis, this recall is worth reading closely. It touches allergen control, potency accuracy, homogeneity, label reconciliation and the credibility of your certificate of analysis all at once. This article breaks down what Health Canada found, the exact rules that apply, and the practical steps that keep your own products off a recall notice. If you want a broader starting point, our cannabis QA compliance checklist and our explainer on how edibles and extracts are classified give useful context.

What Health Canada actually found

In short: a licensed processor sold edible cannabis with undeclared milk and hazelnut and with cannabinoid content that did not match the label. Health Canada identified the problem through its own inspection and sampling, published recall RA-82393 on 22 July 2026, and it remained listed as an active recall into early August. About 6,770 units had been distributed through the Ontario Cannabis Store and a Saskatchewan distributor between March 2025 and May 2026.

The recalling firm was 10392804 Canada Inc., operating as Sweet Vengeance, under the brand Social Sessions. The gap between what the label promised and what the laboratory measured is set out in the Health Canada recall notice and summarised below.

Read the table as an inspector would. Two products labelled to contain THC delivered zero. One product labelled at 10 milligrams of THC delivered no CBD at all. And one product labelled at 1 milligram of THC tested at 3.38 milligrams, with CBD at 59.22 milligrams against a labelled 25. That single product over-delivered THC by more than three times, which is a consumer over-intoxication risk, not a paperwork error.

Why vegan is an allergen control claim, not a marketing word

What it is: on an edible product, vegan, plant based and dairy free are claims about composition, and composition is where allergens live. Why it matters: if a product says vegan and contains milk, you have a false claim and an undeclared allergen at the same time. Health Canada treats the allergen as the safety issue and the claim as the aggravating factor.

Milk and tree nuts, including hazelnut, are priority food allergens in Canada. The food allergen source, gluten source and added sulphites statement requirements that apply to foods also reach edible cannabis through the labelling provisions in Part 7 of the Cannabis Regulations. A vegan claim does not remove the duty to declare an allergen. It raises the stakes, because allergic consumers rely on that claim to decide the product is safe for them.

The control failure here is not exotic. It is cross contamination or a formulation change that was not caught by specification control, supplier verification or label reconciliation. This is exactly the discipline food manufacturers apply every day, and it is the discipline that cannabis processors, who often come from a cultivation background, are least likely to have built.

The potency gap: there is no cannabinoid tolerance limit

Direct answer: Canada's Cannabis Product Accuracy Rules, in sections 133 to 136 of the Cannabis Regulations, apply to the declared net weight and volume of a product and to unit, container, plant and seed counts. They do not set a tolerance limit for THC or CBD content. Many people assume a percentage tolerance exists for cannabinoids. It does not.

So where does the duty to get potency right come from? Three places. First, the labelling provisions in Part 7 of the Cannabis Regulations require the label to state the quantity of THC and CBD the product could yield. Second, section 25 of the Cannabis Act prohibits selling cannabis that is not packaged and labelled in accordance with the regulations. Third, and most powerfully, section 18 of the Cannabis Act prohibits false, misleading or deceptive representations, and it names strength, concentration and potency specifically. The accuracy rules themselves confirm what they do, and do not, cover.

How an inspector found it before the licence holder did

What it is: the recall states it was initiated after Health Canada inspected the facility and conducted sampling and testing. Why it matters: the licence holder's own quality system did not detect five failing products across fourteen months of continuous sale. That is a system failure, not a single bad batch.

This is the sentence that should worry every processing licence holder. If Health Canada sampled your product tomorrow, would its result match your certificate of analysis? A fourteen month gap points to something structural: release testing that did not include the right analytes, a homogeneity problem that batch sampling missed, a certificate of analysis that was trusted without challenge, or a label that was never reconciled against the tested result. Our guide to passing a Health Canada cannabis inspection covers how inspectors approach exactly these questions.

A defensible corrective and preventive action, or CAPA, does not stop at re-labelling the product. It asks why the quality system allowed the gap to persist, tests that root cause, and verifies that the fix works. A CAPA that treats a fourteen month detection failure as a printing error will not survive the next inspection, which is why root cause investigations that hold up matter so much.

Good Production Practices and QAP release: where this should have been caught

What companies should do: use the Good Production Practices in Part 5 of the Cannabis Regulations, and the quality assurance person release step, as the controls that catch this kind of failure before product ships. Good Production Practices require sanitation, standard operating procedures, testing and a quality assurance person who approves each lot for release.

The quality assurance person, or QAP, is the last line of defence. A QAP who reviews each lot against its specification, checks the certificate of analysis against the label, and confirms allergen controls were followed would have flagged milk in a vegan product and a THC result of zero against a label of one milligram. Homogeneity and content uniformity studies exist to prove the cannabinoid is evenly distributed, so the number on the label is the number in every unit. When those studies are weak, potency results scatter, exactly as they did here. Our overview of Good Production Practices for cannabis sets out what a compliant system looks like.

None of this is unique to cannabis. It is standard pharmaceutical and food quality thinking applied to a cannabis licence. That is the gap we see most often: a cannabis operator with strong cultivation and security controls, and a quality system that was never built to a manufacturing standard. It is the core of our cannabis and hemp regulatory support.

Compliance checklist: a 12-point cannabis allergen and potency self-assessment

Use this checklist to pressure test your own programme. If you cannot answer yes to each item with a record to prove it, that is where to start.

• Every edible recipe has a current specification that lists all ingredients, allergens and the target THC and CBD content.
• Any vegan, plant based, dairy free or allergen free claim is supported by ingredient specifications and supplier documentation, not just marketing intent.
• Priority allergens, including milk, eggs, tree nuts such as hazelnut, peanuts, soy, wheat and sulphites, are risk assessed for every product and every shared line.
• An allergen control programme covers segregation, scheduling, dedicated equipment or validated cleaning, and changeover verification.
• Cleaning between products with different allergen profiles is validated, not assumed, with a record for each changeover.
• Incoming ingredients are verified against their specification and certificate of analysis, and any supplier change triggers a re-assessment.
• Release testing includes cannabinoid content and, where relevant, allergen verification, using validated analytical methods.
• A homogeneity or content uniformity study proves THC and CBD are evenly distributed across each production lot.
• The label is reconciled against the tested certificate of analysis before release, so the printed THC and CBD match the batch result. See our tips on preventing labelling errors.
• The quality assurance person approves each lot for release against its specification, with real authority to reject.
• A recall procedure is documented and tested through a mock recall, and can trace every unit to its distributor within hours.
• A CAPA process investigates root cause, tests the cause, and verifies the fix, rather than re-labelling and moving on.

Common mistakes this recall exposes

The most damaging mistake is treating a marketing claim as separate from allergen control. A vegan claim is a composition claim, and composition is a safety control. When marketing and quality are not aligned, a reformulation or a shared line quietly turns a compliant label into a false one.

The second mistake is trusting the certificate of analysis without reconciliation. A certificate is only as good as the sampling behind it. If your homogeneity is poor, a certificate can look fine while individual units fail. Reconcile the tested value against the label, every lot.

The third mistake is assuming a cannabinoid tolerance exists. Teams sometimes wave away a small potency miss as within tolerance. There is no tolerance band for THC or CBD. The number you print is the number you must defend.

The fourth mistake is a shallow CAPA. A fourteen month gap is a quality system failure. Re-labelling the product and closing the file invites the same finding again, and inspectors notice repeat root causes.

Frequently asked questions

Do edible cannabis products in Canada have to declare allergens?

Yes. Edible cannabis is subject to labelling requirements under Part 7 of the Cannabis Regulations, which incorporate the food allergen source, gluten source and added sulphites statement approach used for foods. Priority allergens such as milk and tree nuts must be declared, and a vegan or dairy free claim does not remove that duty.

Is there a legal tolerance for THC content compared with the label in Canada?

No. The Cannabis Product Accuracy Rules in sections 133 to 136 of the Cannabis Regulations cover net weight, volume and unit counts, not cannabinoid content. There is no percentage tolerance for THC or CBD. The label must state the quantity the product could yield, and section 18 of the Cannabis Act prohibits false or misleading representations about strength and potency.

Can a cannabis edible be labelled vegan in Canada?

It can, but only if the claim is true and substantiated. If a product labelled vegan contains milk, as in recall RA-82393, the licence holder faces both a false claim and an undeclared allergen. Any vegan, plant based or dairy free claim must be supported by ingredient specifications, supplier verification and allergen controls.

What happens when Health Canada finds a problem during an inspection?

Health Canada can require a recall, take compliance and enforcement action, and increase inspection frequency. In RA-82393, the recall was initiated after Health Canada inspected the site and tested product. A regulator detected defect, rather than a self detected one, signals a quality system weakness and usually draws closer scrutiny.

Who is responsible for reporting a cannabis recall to Health Canada?

The licence holder is responsible. Under the Cannabis Regulations, holders must maintain a system that allows them to recall product and must notify Health Canada. A tested recall procedure and full traceability to each distributor let you act within hours rather than days.

How can a processor prevent this kind of recall?

Build an allergen control programme, validate cleaning between products, verify suppliers, include cannabinoid content and homogeneity in release testing, reconcile the label against the certificate of analysis, and give the quality assurance person real authority to reject. A gap assessment and a mock recall will show where your programme is weakest before an inspector does.

Would your product pass Health Canada's test, or only your own? If you are not certain, that is the conversation to have now.

Conclusion

Recall RA-82393 is a compact lesson in modern cannabis quality. A vegan claim became an allergen failure, a label became a potency misstatement, and a quality system missed both for fourteen months until an inspector did the testing. None of the underlying controls are exotic. They are the allergen management, homogeneity, label reconciliation and QAP release steps that a manufacturing grade quality system takes for granted. Build them now, and you never appear on a notice like this one.
