In Canada’s food industry, maintaining effective Good Manufacturing Practices (GMP) is essential for producing safe food, meeting regulatory requirements, satisfying customer expectations, and preparing for food safety audits.
A GMP auditor evaluates whether a food operation is following appropriate manufacturing, sanitation, hygiene, maintenance, personnel, storage, and documentation practices. A well-conducted GMP audit can help identify gaps before they become regulatory, customer, or food safety problems.
Whether you operate a food manufacturing facility in Toronto, a processing plant in Montreal, or a distribution operation elsewhere in Canada, GMP auditing can provide a structured way to evaluate your food safety controls and identify opportunities for improvement.
At Arnika, we provide GMP auditing, food safety assessments, internal audits, gap assessments, corrective-action support, and certification-readiness consulting for food businesses across Canada.

What Is a GMP Auditor?
A GMP auditor is a food safety professional who evaluates whether a facility’s operations, practices, and documented systems conform to applicable Good Manufacturing Practices and other relevant requirements.
Depending on the purpose and scope of the audit, a GMP auditor may assess:
- Facility condition and hygiene
- Personnel hygiene and practices
- Cleaning and sanitation
- Equipment maintenance
- Pest control
- Allergen controls
- Cross-contamination prevention
- Storage and material handling
- Supplier controls
- Documentation and records
- Traceability
- Corrective actions
- Employee training
The objective is to identify areas of conformity and non-conformity, evaluate food safety risks, and provide practical information that can be used to improve the operation.
A GMP audit can also form part of a broader food safety audit or certification-readiness assessment.
Why Are GMP Audits Important for Food Businesses?
GMP audits provide a systematic way to evaluate whether food safety practices are actually being implemented in the facility—not simply documented in procedures.
A well-designed audit can help identify problems involving:
- Sanitation
- Employee hygiene
- Facility conditions
- Equipment maintenance
- Pest control
- Allergen management
- Storage
- Documentation
- Supplier controls
- Corrective actions
These areas are important because Canadian preventive-control requirements include controls relating to the sanitary operation and maintenance of food establishments, personnel, equipment, storage, and other food safety activities.
Regulatory Compliance
GMP practices can support compliance with applicable Canadian food safety requirements.
For businesses subject to the Safe Food for Canadians Regulations (SFCR), preventive-control requirements are based on internationally recognized food hygiene principles, including Good Manufacturing Practices and HACCP principles.
A GMP audit can therefore help a business identify weaknesses in the operational controls that support its broader food safety system.
Customer and Retailer Requirements
Many food manufacturers and suppliers must meet additional customer, retailer, or contractual requirements.
A GMP audit can help identify gaps before a customer audit or supplier assessment.
Certification Readiness
Strong GMP and prerequisite controls are also important components of many food safety certification systems, including:
- SQF
- BRCGS
- FSSC 22000
- Other GFSI-recognized certification schemes
A GMP assessment can therefore be useful before beginning a formal certification audit.
Risk Reduction
Weak GMP practices can contribute to:
- Food contamination
- Allergen cross-contact
- Sanitation failures
- Pest activity
- Product complaints
- Recalls
- Regulatory non-compliance
Regular internal assessments can help organizations identify these issues earlier and establish corrective actions.
Continuous Improvement
GMP auditing should not be viewed only as a pass/fail exercise.
An effective audit can help management identify recurring problems, prioritize corrective actions, and improve the effectiveness of the food safety system over time.
What Does a GMP Audit Include?
The scope of a GMP audit depends on the facility, products, processes, regulatory requirements, customer requirements, and purpose of the audit.
A typical food manufacturing GMP audit may evaluate:
Facility and Grounds
- Building condition
- Facility layout
- Structural integrity
- Drainage
- Lighting
- Ventilation
- Doors and windows
- Personnel and material flow
Personnel Hygiene
- Handwashing
- Protective clothing
- Personal hygiene
- Employee practices
- Illness reporting
- Training
Cleaning and Sanitation
- Cleaning procedures
- Sanitation schedules
- Cleaning records
- Chemical control
- Verification of sanitation effectiveness
Equipment and Maintenance
- Equipment condition
- Preventive maintenance
- Calibration
- Hygienic equipment design
- Foreign-material risks
Pest Control
- Pest-control program
- Monitoring devices
- Inspection records
- Corrective actions
- Evidence of pest activity
Allergen Management
- Allergen identification
- Storage
- Handling
- Cross-contact prevention
- Cleaning
- Labelling controls
Storage and Temperature Control
- Raw-material storage
- Finished-product storage
- Temperature monitoring
- Stock rotation
- Segregation
- Transportation controls
Supplier Controls
- Approved supplier program
- Supplier documentation
- Specifications
- Certificates and guarantees
- Supplier performance monitoring
Traceability and Recall
- Lot identification
- Traceability records
- Product coding
- Recall procedures
- Mock recall activities
Documentation and Records
- SOPs
- Sanitation records
- Training records
- Maintenance records
- Pest-control records
- Receiving records
- Corrective-action records
- Verification records
GMP Audit Checklist
A GMP audit checklist provides a structured way to evaluate the operation consistently.
Depending on the facility, a GMP checklist may include:
- Facility and grounds
- Personnel hygiene
- Cleaning and sanitation
- Pest control
- Equipment and maintenance
- Water and utilities
- Allergen management
- Storage and temperature control
- Supplier controls
- Waste management
- Traceability
- Recall procedures
- Training
- Documentation and records
- Corrective actions
The checklist should be adapted to the specific operation rather than treated as a generic document.
CFIA guidance similarly emphasizes that preventive controls and PCPs should be appropriate to the particular food business, products, processes, and market requirements.
GMP Audit vs. HACCP Audit
GMP and HACCP are closely connected, but they are not the same thing.
GMP Audit
A GMP audit primarily examines the operational and hygienic conditions that support safe food production, including:
- Sanitation
- Personnel hygiene
- Facility conditions
- Equipment
- Pest control
- Storage
- Maintenance
- Documentation
HACCP Audit
A HACCP audit focuses more specifically on the hazard analysis and HACCP system, including:
- Hazard identification
- Hazard analysis
- Control measures
- Critical Control Points (CCPs)
- Critical limits
- Monitoring
- Corrective actions
- Verification
- Records
GMP and prerequisite controls provide an important foundation for HACCP-based food safety systems. CFIA’s preventive-control guidance includes prerequisite programs addressing areas such as premises, equipment, personnel, sanitation, pest control, recall, and operational controls.
For businesses that need both systems reviewed, Arnika can conduct a broader HACCP consulting and food safety assessment.
GMP Auditing and Preventive Control Plans in Canada
For many Canadian food businesses, GMP is part of a broader preventive-control system.
Under the Safe Food for Canadians Regulations (SFCR), preventive-control requirements are designed to prevent food safety hazards and reduce the likelihood of contaminated food entering the Canadian marketplace.
For businesses that require a written Preventive Control Plan, the PCP describes how food safety hazards are identified and controlled and how the business monitors, verifies, and maintains its controls.
This means a GMP audit can be useful as one component of a broader PCP verification or food safety assessment.
However, a GMP audit does not automatically constitute a complete PCP review. The scope should be defined according to the business’s products, processes, regulatory obligations, and food safety system.
For companies importing food into Canada, CFIA has specific PCP guidance for importers, including controls relating to the importer and foreign suppliers.

How GMP Auditing Supports HACCP and Food Safety Programs
GMP controls provide an important operational foundation for HACCP-based food safety systems.
Before relying on HACCP to control significant food safety hazards, a facility needs appropriate prerequisite and preventive controls that address the general conditions necessary for safe food production.
These may include:
- Sanitation
- Personnel hygiene
- Pest control
- Facility maintenance
- Equipment maintenance
- Supplier controls
- Storage controls
- Allergen management
- Training
- Traceability
CFIA identifies prerequisite programs as part of its preventive-control approach, including programs related to premises, food conveyances, equipment, personnel, sanitation and pest control, recall, and operational controls.
Businesses looking to strengthen their complete HACCP system can also explore Arnika’s HACCP consulting services.

What Happens After a GMP Audit?
A useful GMP audit should result in more than a checklist.
Depending on the scope, the final report may identify:
Conformities
Areas where the operation meets the applicable requirements.
Non-Conformities or Gaps
Areas where the operation does not meet the applicable requirement or established procedure.
Observations
Conditions that may require attention even when they do not constitute a formal non-conformity.
Corrective Actions
Actions required to address identified deficiencies.
Root Cause
Where appropriate, the underlying cause of a recurring or significant problem should be investigated.
Follow-Up Verification
Corrective actions should be reviewed to determine whether they were effectively implemented.
This approach helps turn an audit into a continuous-improvement tool rather than simply a compliance exercise.
How Often Should a GMP Audit Be Conducted?
There is no single audit frequency that applies to every food business.
The appropriate frequency depends on factors such as:
- Food safety risk
- Type of operation
- Previous audit findings
- Customer requirements
- Certification requirements
- Regulatory requirements
- Changes to products or processes
- Facility changes
- Recurring non-conformities
A company may conduct internal GMP audits annually, quarterly, or at another risk-based frequency.
The important point is that the audit schedule should be appropriate for the organization’s food safety system and risk profile.
GMP Auditor Services vs. Certification Audits
It is important to distinguish between a consulting or internal GMP audit and an official certification audit.
An internal or consulting GMP audit may help a company identify gaps and prepare for an external audit.
A certification audit, however, is conducted by the applicable independent certification body according to the requirements of the certification program.
Arnika provides consulting, auditing, gap assessment, and certification-readiness support. We do not replace the independent certification body responsible for issuing certification.
