How to Prepare a PMRA-Compliant Pesticide Label: Common Mistakes to Avoid

Posted November 21, 2025

A pesticide label is a legal document that communicates the conditions under which a product can be safely and effectively used. In Canada, the Pest Management Regulatory Agency (PMRA) under Health Canada is responsible for reviewing and approving all pesticide labels to ensure they meet federal regulatory standards.

Preparing a PMRA-compliant pesticide label can be challenging, especially with evolving regulatory expectations and detailed formatting requirements. Below, we will walk through best practices for preparing a compliant label and highlight the most common mistakes to avoid during the process.

Understand PMRA’s Labeling Framework

Before drafting or revising a pesticide label, familiarize yourself with PMRA’s core guidance documents, including:

Label Review Manual – The definitive reference for label content, format, and standard wording.
Regulatory Directive DIR2013-04 – Outlines how labels must clearly communicate risk-reduction measures.
Guidance on Standard Label Phrases – Provides approved wording for precautionary statements, personal protective equipment (PPE), and first aid.

These documents ensure that every section – from product name and guarantee to use directions and storage – meets PMRA’s strict labeling standards.

Maintain Consistency with Approved Product Specifications

A frequent mistake is inconsistency between the label and the approved data package. The following elements must align exactly with the registration data:

Active ingredient names and concentrations
Formulation type (e.g., EC, SC, WP)
Use pattern and application rates
Target pests and crop listings

Always cross-reference the label against the approved Form 6003 (Product Specification Form) to ensure accuracy.

Use Correct and Current Standard Phrases

PMRA requires specific, standardized wording for hazard, precautionary, and first aid statements. Common errors include outdated phrasing or paraphrasing safety statements.
For example:

Incorrect: “Keep away from children.”
Correct (per PMRA standard): “KEEP OUT OF REACH OF CHILDREN.”

Ensure Proper Label Formatting and Layout

Label readability is crucial. Common formatting mistakes include:

Missing or misordered sections
Illegible font size or style
Incorrect placement of hazard symbols or signal words

A well-organized label not only satisfies regulatory reviewers but also reduces risk of user misinterpretation in the field.

Don’t Overlook the Bilingual Requirement

In Canada, all pesticide labels must be bilingual (English and French).

Each section – including hazard statements, directions, and warranty text – must be translated accurately and equivalently.

Include Accurate Company and Canadian Agent Information

If the registrant is not based in Canada, the label must include the Canadian agent’s name, address, and contact details. Omitting or providing outdated contact information is a common compliance gap.

Any change in Canadian representation or regulatory mailing address requires a Notification submission (Category Y.2.1 or Y.2.2) to PMRA.

Conclusion

A PMRA-compliant pesticide label not only meets regulatory obligations but also ensures safe, effective use of the product in the Canadian market. Most labeling deficiencies arise from small but avoidable errors – inconsistent data, outdated standard phrases, or formatting oversights.
