1.0 Pesticide active ingredients list and limits

The Pest Management and Regulatory Agency maintains a list of historical and current pest control products (PCPs) used in Canada. Only certain PCPs have been approved in Canada for use on cannabis.

PCPs that are of the most concern or are most likely to be used on cannabis have been added to this pesticide active ingredients list if they:

  • were detected on cannabis in Canada or in American states that have regulated its production
  • are used against pests that can be found on cannabis
  • were observed by inspectors of Health Canada or the Canadian Border Services Agency
  • were identified because of their risk to health or the environment, or because of other factors

Health Canada has set limits of quantification (LoQ) for pesticide active ingredients in each matrix (i.e., fresh cannabis and cannabis plants, dried cannabis, and cannabis oil). These limits are based on the identification and quantification of the molecule using current chemical analytical methods and equipment. The values may differ between each matrix because of specific constraints associated with analyzing each product type.

The pesticide active ingredients list will be reviewed periodically and revised as needed as Health Canada monitors the industry for pesticide active ingredients and advances in chemical analysis technology.

Health Canada has the authority to take action if an unauthorized PCP is used by licence holders under the Cannabis Act and its Regulations and under the Pest Control Products Act and its Regulations, whether or not the PCP is listed in this document and regardless of the level of contamination.

Health Canada encourages anyone who suspects that an unauthorized PCP not listed in this document is being used on cannabis to communicate with the Cannabis Legalization and Regulation Branch at cannabis@canada.ca.

2.0 Limits under development

In the table below, limits that are identified with an asterisk (*) are still being developed by Health Canada and will be added as they become available. Licence holders will be notified when these limits are finalized, at which point these limits will become part of the Mandatory cannabis testing for pesticide active ingredients - Requirements.
