Natural Health Product (NHP) companies in Canada must maintain appropriate quality assurance oversight, but they are not necessarily required to employ a full-time Quality Assurance Person (QAP). Health Canada’s Good Manufacturing Practices (GMP) guidance recognizes that qualified external consultants may fulfill the QAP role, provided they meet applicable requirements for qualifications, independence and authority.
Outsourced quality assurance can be a practical option for smaller manufacturers, importers, distributors and businesses with fluctuating quality assurance needs. Companies may appoint an external QAP or engage consultants to support specific activities, including batch release, supplier qualification, GMP audits, investigations, corrective and preventive actions (CAPA), and inspection readiness.
However, outsourcing does not transfer regulatory accountability to the service provider. Organizations remain responsible for maintaining effective quality systems and ensuring that qualified personnel have the resources and authority necessary to perform their assigned responsibilities.
Under Section 51 of the Natural Health Products Regulations, every manufacturer, packager, labeller, importer and distributor must have a qualified Quality Assurance Person (QAP). However, the Regulations do not require the QAP to be a permanent employee.
Health Canada’s Good Manufacturing Practices Guide for Natural Health Products (GUI-0158), Version 4, effective March 4, 2026, recognizes that companies may engage qualified consultants to fulfill QAP responsibilities. The individual must possess the appropriate training, experience and technical knowledge and have sufficient authority to make independent quality decisions.
For example, a small Canadian NHP importer receiving several shipments per month may not require a full-time quality assurance department. Instead, the importer could appoint an external QAP to review quality documentation, oversee importation controls and approve products before release for sale.
This arrangement is permissible when the external QAP has adequate knowledge of the company’s operations, access to relevant records and sufficient availability to fulfill the role. The same regulatory requirements apply regardless of whether the QAP is employed internally or engaged through a consulting agreement.
For a detailed explanation of the position’s responsibilities, see dicentra’s article, What Does a Quality Assurance Person Do for Natural Health Products?
Outsourcing quality assurance can involve appointing an external professional as the company’s designated QAP or engaging consultants to supplement an existing internal quality assurance function.
An outsourced QAP assumes the responsibilities assigned to the position under the Natural Health Products Regulations. Depending on the organization’s activities, these may include reviewing specifications, approving materials and procedures, evaluating quality documentation, investigating deviations and authorizing finished-product release.
For example, an NHP distributor may appoint an external QAP to oversee applicable GMP requirements, including complaints, returns, storage controls and quality documentation.
Outsourced QA support, on the other hand, involves engaging external specialists to assist with particular activities while the company’s designated QAP retains their assigned responsibilities.
An established NHP manufacturer preparing for a Health Canada inspection might engage a consultant to review its GMP procedures, conduct a gap assessment and assist with CAPA development. The internal QAP would continue overseeing the organization’s quality system and making the required quality decisions.
Both arrangements can provide access to specialized expertise, but the responsibilities, authority and availability of the external professional must be clearly established.
The suitability of outsourced quality assurance depends on the organization’s size, operational complexity, product portfolio and available internal resources.
For companies with relatively limited or intermittent quality assurance requirements, maintaining a full-time QA department may not be financially practical. However, businesses with continuous manufacturing operations or complex quality systems may require dedicated internal personnel to maintain effective oversight.
| Business Type or Activity | Suitability | Potential Outsourced QA Support | Key Considerations |
| Small NHP manufacturers | High, depending on production complexity | External QAP, batch review, SOP development, GMP oversight and CAPA | Requires sufficient availability and familiarity with manufacturing operations. |
| NHP importers | High | External QAP, importation controls, documentation review and product release | Imported products must meet Canadian requirements before release. |
| NHP distributors | High | External QAP, complaint investigations, returns and storage controls | Distributors remain subject to applicable GMP requirements. |
| Contract manufacturers | Moderate to high | Supplier qualification, GMP audits, investigations and CAPA | Continuous production may require dedicated internal QA personnel. |
| NHP brand owners | High for supplemental support | Contract manufacturer oversight, quality agreements and supplier audits | Responsibilities depend on the company’s activities and licensing arrangements. |
| Companies preparing for inspections | High | GMP gap assessments, mock inspections, CAPA and training | External support can supplement existing personnel. |
| Companies with temporary staffing gaps | High | Interim QAP services and temporary QA management | Qualified coverage and continuity must be maintained. |
| Large manufacturers | Moderate for supplemental support | Specialized audits, remediation projects and technical investigations | Permanent internal QA personnel may be more practical. |
These suitability assessments reflect operational considerations rather than formal classifications established by Health Canada.
Importers and distributors are particularly suitable candidates for outsourced quality assurance because their activities may not require the same level of daily oversight as domestic manufacturing operations.
For example, a Canadian importer purchasing finished NHPs from a foreign manufacturer must ensure that the products meet Canadian specifications and GMP requirements before release. An external QAP may review Certificates of Analysis, evaluate supporting documentation and oversee the importer’s quality system without being employed directly by the company.
Similarly, an NHP distributor may require qualified oversight of complaints, returns, storage conditions and other applicable GMP activities without needing a full-time QA department.
Health Canada’s NHP GMP guidance recognizes the use of third-party QAPs, provided the arrangements establish appropriate qualifications, authority and oversight.
Smaller manufacturers may benefit from outsourced quality assurance when production volumes are limited or quality-related activities occur intermittently.
For example, a company producing a small portfolio of NHP capsules may require periodic review of batch records, specifications, supplier documentation and finished-product testing results. An external QAP could provide this oversight if the arrangement allows for timely decisions and adequate supervision of the manufacturing activities.
Periodic document review alone is insufficient if the arrangement does not provide appropriate oversight and access to quality decisions while operations are taking place
Growing businesses may also use outsourced consultants to address temporary increases in workload, support the introduction of new products or provide specialized expertise without immediately expanding their permanent workforce.
However, outsourcing does not eliminate the need for trained operational personnel, appropriate on-site controls or effective communication between production and quality assurance.
The decision to outsource quality assurance should consider more than the cost of employing a full-time QAP. Organizations must also evaluate operational requirements, technical expertise, availability and the complexity of their quality systems.
| Consideration | In-House Quality Assurance | Outsourced Quality Assurance |
| Cost structure | Salary, benefits, training and overhead | Contracted fees based on agreed services |
| Availability | Integrated into daily operations | Defined through the service arrangement |
| Technical expertise | Depends on internal qualifications | May provide access to specialized GMP expertise |
| Operational familiarity | Developed through ongoing involvement | Requires onboarding and communication |
| Scalability | Additional capacity may require hiring | Support can be adjusted as needs change |
| Independence | Requires appropriate internal controls | May provide separation from commercial functions |
| Regulatory responsibility | Organization remains accountable | Organization remains accountable |
For a small importer receiving occasional shipments, an external QAP may provide the necessary oversight at a lower overall staffing cost than a permanent employee. Conversely, a manufacturer operating several production lines may find that dedicated internal QA personnel are more efficient because quality decisions are required throughout the working day.
External consultants can also provide specialized expertise for activities that occur less frequently, such as supplier audits, complex investigations or inspection remediation. This allows companies to supplement their existing resources without maintaining every technical specialty internally.
Regardless of the arrangement, Health Canada expects quality decisions to remain independent of inappropriate commercial or production pressures.
Many NHP quality assurance activities can be performed or supported by qualified external professionals, provided the organization’s regulatory responsibilities and quality controls remain intact.
Batch Review and Product Release
Under Section 51(4) of the Natural Health Products Regulations, every lot or batch must receive QAP approval before being made available for sale.
An external QAP supporting an NHP importer may review Certificates of Analysis, finished-product specifications and other supporting documentation before approving a shipment for release. The QAP must have sufficient information to determine whether the product meets applicable requirements and must be able to withhold approval when necessary.
Supplier Qualification and Contract Manufacturer Oversight
Companies that rely on external manufacturers, laboratories and ingredient suppliers must maintain appropriate oversight of those relationships.
For example, a Canadian NHP company working with an overseas contract manufacturer may engage a QA consultant to evaluate GMP documentation, review supplier qualifications and establish quality agreements.
Health Canada’s GMP guidance on operations emphasizes the importance of controlling contracted activities and maintaining appropriate documentation.
Deviations, Investigations and CAPA
External QA specialists may assist with investigating deviations, evaluating out-of-specification results and developing corrective and preventive actions.
For example, an NHP manufacturer receiving an unexpected laboratory result may require additional expertise to assess the potential causes, determine whether other batches are affected and establish appropriate corrective actions.
The designated QAP must retain the relevant oversight and approval responsibilities, even when external specialists assist with the investigation.
GMP Documentation and Inspection Readiness
Consultants can also assist with SOP development, quality system reviews, internal audits, GMP gap assessments and inspection preparation.
For example, a company preparing for a Health Canada inspection may engage an external specialist to evaluate its documentation, identify compliance gaps and help implement corrective actions.
This support can be particularly useful for companies with limited internal resources or those adapting their quality systems to updated regulatory guidance.
An outsourced QAP arrangement must provide the same level of qualified oversight expected of an internal QAP. Health Canada’s guidance emphasizes appropriate qualifications, independence, accessibility and documented responsibilities.
Companies considering outsourced quality assurance should address the following requirements.
Qualifications and experience: The external QAP must possess training, experience and technical knowledge relevant to the company’s activities. For example, a consultant overseeing imported NHPs must understand Canadian importation controls and the documentation required to support product release.
Defined responsibilities and authority: Written agreements should identify the services being performed, responsibilities assigned to the QAP and activities retained by internal personnel. The QAP must have the authority to make independent quality decisions, including rejecting products when necessary.
Access to documentation and recordkeeping: External quality personnel must have timely access to the records needed to perform their responsibilities, including applicable specifications, batch records, laboratory results, supplier documentation and investigation reports. The company must also ensure that all documents and records it is required to maintain remain available at its premises, even when the related activities are outsourced.
Availability and continuity: The QAP must provide oversight during each working shift involving activities under their control. They may work off-site if fully accessible and sufficiently familiar with on-site operations to fulfil their responsibilities. Qualified designates should provide coverage when necessary, with documented responsibilities and communication procedures.
Ongoing oversight: The organization must continue monitoring its quality system and outsourced activities. A service agreement does not transfer its regulatory obligations to the consultant.
For example, an NHP importer engaging an external QAP should establish procedures for communicating shipment arrivals, providing quality documentation, obtaining product-release approvals and addressing unexpected quality issues. These arrangements should be documented and consistently followed.
Health Canada’s current GMP guidance recognizes the use of quality agreements to define responsibilities between organizations and contracted service providers.
