Good Manufacturing Practices (GMP) are the practices, procedures, and controls used to help ensure that products are consistently manufactured under appropriate conditions and meet applicable safety and quality requirements.
But what does GMP mean, and what does it actually involve for Canadian businesses?
GMP can apply differently depending on the product, industry, and regulatory framework. For food businesses, GMP-related practices include sanitation, employee hygiene, facility maintenance, equipment controls, process controls, and documentation.
For businesses building a broader food safety system, GMP is commonly part of the foundation supporting programs such as HACCP and other food safety management systems.
This guide explains the GMP meaning, what GMP stands for, the main elements of GMP, and how Canadian businesses can use GMP practices to strengthen food safety and regulatory compliance.

What Is the GMP Meaning in Food Safety?
In food safety, GMP generally refers to the basic operational practices that help prevent contamination and maintain safe and consistent production conditions.
GMP does not replace a complete food safety hazard analysis.
Instead, GMP and other prerequisite programs provide the operational foundation on which a food safety system can be built.
Examples include:
- Employee hygiene
- Cleaning and sanitation
- Pest control
- Equipment maintenance
- Water and ice controls
- Waste management
- Allergen controls
- Supplier controls
- Storage conditions
- Facility maintenance
These controls help establish the conditions necessary for effective HACCP systems.
Why Is GMP Important?
A properly implemented GMP system helps a business control the conditions under which products are manufactured, processed, handled, stored, and distributed.
1. Helps Protect Product Safety
Good manufacturing practices help reduce opportunities for contamination and other production-related risks.
2. Supports Regulatory Compliance
GMP practices can help businesses demonstrate that appropriate sanitary and operational controls are in place.
For Canadian food businesses, GMP should be considered together with applicable Canadian Food Inspection Agency (CFIA) requirements and the Safe Food for Canadians Regulations (SFCR).
3. Improves Consistency
Documented procedures and employee training help ensure that important activities are performed consistently.
4. Supports HACCP and Food Safety Systems
GMP and prerequisite programs establish basic operating conditions that support hazard-based food safety systems.
5. Helps Prepare for Audits
A well-maintained GMP system can provide evidence of effective controls during customer, certification, or regulatory assessments.
What Are the Main Elements of GMP?
Although requirements vary by industry, effective GMP programs commonly address several core areas.
Facility and Premises
Facilities should be designed, maintained, and operated to minimize contamination risks and support effective cleaning and production.
This can include:
- Appropriate workflow
- Suitable construction materials
- Adequate lighting
- Proper drainage
- Controlled access
- Preventive maintenance
Personnel Hygiene
Employees should understand and follow hygiene requirements appropriate to their responsibilities.
This may include:
- Handwashing
- Protective clothing
- Personal hygiene
- Illness reporting
- Hygiene training
- Controlled movement within production areas
Cleaning and Sanitation
Cleaning and sanitation procedures should define:
- What must be cleaned
- How it is cleaned
- Which chemicals are used
- How frequently cleaning occurs
- Who is responsible
- How effectiveness is verified
Equipment Maintenance
Equipment should be maintained in a condition that prevents contamination and supports consistent production.
Maintenance activities should be documented where appropriate.
Raw Material and Supplier Controls
Businesses should establish appropriate controls for receiving and handling raw materials and packaging materials.
Supplier approval and verification can be particularly important where incoming materials may affect food safety.
Process Controls
Production processes should be controlled using documented procedures, specifications, and appropriate monitoring.
Documentation and Records
Records provide evidence that procedures and controls are actually being implemented.
Depending on the operation, records may include:
- Sanitation records
- Temperature records
- Maintenance records
- Receiving records
- Training records
- Inspection records
- Corrective action records
Traceability
Businesses should maintain appropriate records to identify products, materials, suppliers, and distribution information.
Traceability is particularly important when responding to a food safety incident or recall.
GMP vs HACCP: What Is the Difference?
GMP and HACCP are related but they are not the same thing.
GMP focuses primarily on the general conditions and practices required to produce products safely and consistently.
HACCP is a systematic approach for identifying and controlling significant food safety hazards.
For a food business, GMP and prerequisite programs can provide the foundation needed to implement an effective HACCP system.

Is GMP Required in Canada?
There is not one single GMP requirement that applies identically to every industry and every Canadian business.
GMP obligations depend on the product, activity, and applicable regulatory framework.
For example, different requirements may apply to:
- Food
- Pharmaceuticals
- Natural health products
- Cosmetics
- Medical devices
- Other regulated products
Food businesses should determine their obligations based on their specific activities and applicable federal or provincial requirements.
For federally regulated food businesses, GMP-related sanitary and preventive controls form part of the broader food safety framework overseen by the CFIA.
If you operate a food business in Canada, you may also need a Preventive Control Plan (PCP).
How to Implement GMP in a Food Business
Implementing GMP is not simply a matter of creating a manual.
The system needs to reflect the actual operation.
Step 1: Assess Your Current Operations
Conduct a GMP gap assessment to identify weaknesses in areas such as:
- Hygiene
- Sanitation
- Facility conditions
- Equipment
- Documentation
- Employee practices
- Supplier controls
Step 2: Develop Appropriate Procedures
Create practical SOPs and prerequisite programs that reflect the actual operation.
Step 3: Train Employees
Employees should understand both what they need to do and why the controls are important.
Step 4: Implement Records
Use appropriate records to demonstrate that procedures and controls are being followed.
Step 5: Verify the System
Conduct inspections, internal audits, record reviews, and other verification activities.
Step 6: Correct Problems and Improve
When deficiencies are identified, determine the root cause, implement corrective actions, and verify that the issue has been effectively addressed.
For businesses preparing for certification, Arnika also provides food safety auditing and audit-preparation services.
GMP and Food Safety Certification
GMP practices can also support businesses preparing for recognized food safety certification programs.
Depending on the operation and certification scheme, GMP-related controls may form part of the foundation for systems such as:
- HACCP-based programs
- SQF
- BRCGS
- FSSC 22000
However, GMP alone does not mean that a business is certified under these schemes.
Certification involves additional requirements and an assessment by an applicable independent certification body.
You can learn more about SQF certification and BRCGS certification in Canada.
Common GMP Problems Found During Audits
Some recurring GMP deficiencies include:
- Poor employee hygiene practices
- Inadequate cleaning
- Incomplete sanitation records
- Poor facility maintenance
- Improper equipment condition
- Inadequate pest-control controls
- Inconsistent documentation
- Poor material identification
- Weak supplier controls
- Inadequate corrective actions
A GMP gap assessment can help identify these issues before a customer, certification, or regulatory audit.
