Good Production Practices audit preparation is how a Canadian Licensed Producer demonstrates to Health Canada that its quality systems work in practice, not just on paper. A GPP audit examines sanitation, quality assurance, recall readiness, testing, record-keeping, and personnel qualifications. For an export-focused LP, passing cleanly protects licence continuity, and licence continuity protects every shipment that depends on it. The producers who pass smoothly are the ones who treat audit readiness as a year-round state rather than a pre-audit scramble.
This guide covers what a GPP audit looks at, how to prepare, the documentation that holds up under scrutiny, and the mistakes that turn a routine audit into a finding.
What a GPP audit examines
Health Canada assesses Good Production Practices under the Cannabis Act and the Cannabis Regulations. The audit looks at whether the LP's operations meet GPP requirements across several areas: sanitation programmes, the quality assurance function and the qualified person who releases lots, recall procedures, testing practices, and the completeness of records.
The underlying question an auditor is answering is whether the LP's written procedures match what actually happens on the floor. A polished manual that does not reflect daily practice is a liability, not an asset.
Records are the backbone
Most audit outcomes turn on documentation. Batch records, sanitation logs, training records, deviation and corrective action reports, and testing results all need to be complete, contemporaneous, and retrievable. An LP that can produce the right record quickly demonstrates control. One that scrambles to reconstruct records signals the opposite.
How to prepare for a GPP audit
Preparation is less about a last-minute push and more about maintaining an audit-ready state. The practical steps most well-run LPs follow include:
- Keep batch records, sanitation logs, and training records current and contemporaneous
- Run internal mock audits against the GPP requirements to surface gaps early
- Confirm the quality assurance person and qualified person roles are properly documented
- Verify that written procedures match actual floor practice, and update whichever is wrong
- Close out open deviations and corrective actions before the audit, not during it
The same documentation discipline that supports ISO/IEC 17025 accredited testing supports GPP readiness, because both rest on complete, traceable records. Maintaining the licence itself through renewals and amendments is the related discipline covered in our guide on licence renewals and amendments.
Why this matters for export-focused LPs
For an LP supplying international markets, a GPP finding is not just a domestic compliance issue. It can delay a renewal, complicate an amendment, and undermine the confidence of importers who scrutinise a supplier's compliance record. A clean GPP history is part of what makes a Canadian LP credible to a German, Australian, or Israeli partner.
Export documentation also draws on the same records the audit examines. The batch records and testing results that satisfy an auditor are the same evidence an importer and the EU-GMP framework expect to see, which is why a well-run quality system pays off on both fronts.
Common mistakes LPs make
The first mistake is treating the audit as an event to prepare for rather than a state to maintain, which produces last-minute gaps. The second is letting written procedures drift away from actual practice, so the manual and the floor tell different stories. The third is leaving deviations and corrective actions open, which signals that the LP identifies problems but does not close them. Each is avoidable with internal mock audits and clear ownership of the quality function.
AlphaLeaf is a Montreal Licensed Producer of indoor-grown, hand-trimmed cannabis flower with refined genetics. We maintain continuous GPP-compliant operations, ISO/IEC 17025 batch testing, and full traceability, so our compliance record supports both Health Canada audits and the confidence international partners require before they buy. You can review our certifications directly.
Conclusion
A GPP audit rewards LPs who keep their records and practices aligned every day rather than the week before an inspection. For export-focused producers, that readiness protects licence continuity and supply continuity at once.

Frequently Asked Questions
What does a Health Canada GPP audit examine?
It examines whether the LP meets Good Production Practices across sanitation, the quality assurance and qualified person functions, recall procedures, testing, and record completeness. The core question is whether written procedures match actual practice.
How should a Licensed Producer prepare for a GPP audit?
Maintain an audit-ready state year-round: keep records contemporaneous, run internal mock audits, document the QA and qualified person roles, align procedures with floor practice, and close out open deviations before the audit.
Why are records so important in a GPP audit?
Most audit outcomes turn on documentation. Complete, contemporaneous, retrievable batch records, sanitation logs, training records, and corrective actions demonstrate control, while reconstructed records signal the opposite.
How does a GPP finding affect exports?
A finding can delay a licence renewal or amendment and undermine importer confidence. Since export documentation draws on the same records, a clean GPP history strengthens a Canadian LP's credibility with international partners.
What is the most common GPP audit mistake?
Treating the audit as a one-time event to prepare for rather than a state to maintain. That approach produces last-minute gaps, procedures that drift from practice, and unresolved deviations.
