Chairpersons: Jay Parsons and Ingrid Burgetz


As stated in the Aquaculture Activities Regulations (AAR) Regulatory Impact Analysis Statement (Canada Gazette 2014), and reiterated in the s.36 interdepartmental MOU between ECCC, DFO, and HC, DFO requires scientific advice to inform the development of a drug and pesticide monitoring regulatory program and monitoring standard under the AAR. As part of the MOU, partners have established a Science Advice Implementation Plan (SAIP) in order to develop an ongoing interdepartmental science-based research advisory process to inform the development of a post-deposit monitoring program, in addition to the identification of potential actions to take when monitoring indicates that drugs and pesticides used in aquaculture are causing an impact. The results of this process is to be used to inform cost-effective, risk-based post-deposit monitoring, mitigation, and remedial actions, with respect to drugs and pesticides, for future incorporation into the proposed Regulations.
This science advice process will apply to drugs authorized for use under the Food and Drugs Act, and pesticides registered under the Pest Control Products Act. In the Canadian marine finfish aquaculture context, the term drug generally applies to any in-feed product, including both antimicrobial agents (e.g., oxytetracycline) and anti-parasitic products (e.g., SLICE®, active ingredient emamectin benzoate). The term pesticide applies to a pest control product that is applied as an in-bath treatment (e.g., Salmosan®, active ingredient azamethiphos). Additionally, the requested advice and the monitoring program developed based on this advice will inform amended regulations that will help Canada better respond to international commitments made under the North Atlantic Salmon Conservation Organization to protect wild Atlantic Salmon and on prevention of marine pollution under the London Protocol and Convention, two marine pollution prevention treaties to which Canada is party (1996 Protocol to the Convention on the Prevention of Marine Pollution by Dumping of Wastes and Other Matter).
As with the existing AAR regime, the regulatory framework for assessing pesticide and drug deposits will be applied on a site-by-site basis and will consider the active ingredient and its impacts.


The objective of this Science National Peer Review Process is to provide scientific advice on:

This science advice will be used to inform the design and operation of a monitoring program for drugs and pesticides used in marine finfish aquaculture. The program will include pre-impact evaluation (predictive modelling) and post-deposit sampling design and assessment for compliance.This Process will also provide advice on potential mitigation and remediation measures to reduce or eliminate ecosystem impacts from the deposit of pesticides and drugs on the marine environment, and further improve the sustainable management of marine finfish aquaculture in Canada. Knowledge gaps will be identified through the process and may need to be explored further in order to properly develop the monitoring approach.

This Science National Peer Review Process will evaluate the scientific evidence presented in the following working papers:
