Canada: Medical Device Labeling Requirements

Welcome back to MedTech Compliance Chronicles! This week we will be discussing one of the most critical aspects of medical device compliance: labeling. Labels are far more than packaging details; they are the primary way manufacturers communicate essential safety, performance, and usage information to healthcare professionals and patients. In Canada, Health Canada requires that all medical device labeling be accurate, clear, and available in both English and French to ensure safe and effective use across the country.

The Canadian Medical Devices Regulations (CMDR) establish general labeling rules for all medical devices, with additional provisions for in vitro diagnostic devices (IVDs) due to their specific risks and use cases. Clear, well-developed labeling supports both safe use and successful regulatory review, while noncompliant labeling is one of the most serious violations a manufacturer can commit. In fact, a mislabeled device may be considered adulterated, which can have severe consequences for market access. In this post, we will explore Canadian labeling requirements in two parts: first, for general medical devices, and second, for IVDs.

General Medical Devices

For any medical device to be legally sold in Canada, its labeling must contain specific information that enables a user to correctly identify the device and its manufacturer. This includes clearly stating the official name of the device, the name and address of the manufacturer (and importer, if imported into Canada), and the device identifier (UDI, control number, etc.). This information is crucial for establishing traceability and accountability, ensuring that in the event of a quality or safety issue, the source of the device can be accurately and quickly located.

In addition to identifying information, labeling must also describe the device’s intended use, indications for use and contraindications. This information should be clear and complete enough for the user to make a decision on who should and should not use the device under specific conditions. If not self-evident or generally known, directions for use must also be provided, in sufficient detail to allow for the safe and effective use of the device by the target population. 

Labeling must further disclose any special storage, handling, or operating conditions, along with warnings or precautions needed to mitigate risk. This might include requirements for sterility, maximum temperature or humidity levels, or shelf life. Higher-risk devices (Classes III and IV) often require more comprehensive instructions and warnings than lower-risk devices, but in all cases, labeling must be permanent, legible, and accessible under normal conditions of use.

Health Canada does have an electronic instructions for use program available. However, currently this option is for medical devices marketed to healthcare providers only and excludes any devices sold to the general public. The overarching principle being that users must always be able to access the information they need without barriers.

Labeling of IVDs

IVDs must meet the same baseline requirements as other medical devices in Canada, but the regulations add several layers of detail that reflect the unique risks of diagnostic testing. Unlike most devices, IVDs generate clinical information that directly influences treatment decisions. As a result, Health Canada enforces labeling requirements for IVDs surpassing those of general medical devices.

A core component of IVD labeling is the explicit statement of its scientific principle, which is the technical explanation of how the test works. This goes beyond a simple intended use statement by requiring a brief, clear description of the underlying biological, chemical, or immunological method the test employs. This additional detail provides healthcare professionals with the necessary context to understand the test's mechanism and its limitations.

Other significant differences are the requirement to specify the specimen type and collection method, as well as additional equipment required for the test that is not provided with the device. The label must make clear whether the device is intended for blood, urine, saliva, or another sample, and describe any necessary preparation steps. This information ensures specimens are collected and handled in a way that maintains test accuracy. The collection of samples may require the use of pipettes, graduated cylinders or other lab equipment. The samples may also need to be incubated at a certain temperature for a certain period of time or centrifuged to separate components of the sample. In any case, all equipment required to complete the test that is not provided with the test must be communicated to the user. Also, the maximum amount of time between specimen collection and performing the analysis should be stated. 

Final pieces of information to be disclosed include whether the test is qualitative or quantitative, the limitations of the test and any follow up tests that should be taken. Many diagnostic tests are one in a chain of tests that may be performed to narrow down a particular condition a patient is experiencing. Disclosing the limitations and recommended follow ups can further assist the patient or medical professional to proceed in a safe manner.

Conclusion

Clear, compliant labeling is fundamental for any medical device marketed in Canada. Labeling serves as a sort of final line of defense, conveying critical information and ensuring a device can be used safely and effectively by healthcare professionals and patients. Whether your device is an IVD or other medical device, one principle remains constant, there should be no guesswork when using medical devices! When a device is to be used, whom it may and may not be used on, the process of using it and any additional information required for its safe and effective use must be clearly communicated to the end user.
