Framing Challenges and Opportunities for Canada

Gene-editing technologies introduce novel ways to alter the genomes of pest organisms, which could potentially mitigate the impacts of pests in public health, conservation, and agricultural contexts. The use of these tools, however, is accompanied by uncertainties about possible impacts on species and ecosystems, along with broader socioeconomic and cultural risks. Although these technologies are the subject of considerable investigation in controlled testing environments, decision-makers will be tasked with addressing multiple unknowns concerning the efficacy of these tools, their safety, and their appropriateness before implementation can occur in pest-control settings. To do so, Canada will need to leverage expertise in research and development, and in society more broadly. Current regulatory frameworks and their risk assessment processes will require adaptations to meet the scientific and social challenges posed by gene-editing tools. Canada will also need to determine how its regulatory approach will align with international jurisdictions.

Report findings

• The science underpinning gene editing is rapidly evolving and contributes to an increasing variety of prospective mechanisms of action in genetic pest control, across numerous species.
• Climate change is inextricable from the context of pests due to its potential impacts on ecosystems and pest biology, leading to a complex interplay among key pests, their control, and climate change in Canada.
• Canada is not currently undertaking intensive research and development activity in gene-edited organisms for pest control, despite having research capacity in related fields. Better alignment among Canada’s main public research funders is needed to develop the necessary personnel, and channel the correct expertise, toward responsible technology development.
• The risk assessment process is central to decision-making in pest control, but its legitimacy hinges on a body of evidence that does not currently exist for genetic pest-control programs. Adaptive risk assessment is a necessary tool to account for the evolving body of evidence related to genetic pest control, and can be used to obtain valuable stakeholder and Rights-holder input for risk identification and prioritization.
• Conducting public engagement is a core component of pest management activities, especially with regard to impacted communities and at-risk ecosystems. Increased participation from publics can align with ethical practices and bolster a program’s effectiveness.
• Canada’s current regulatory framework for pest control uses a case-by-case approach; the diversity of potential gene-edited organisms could test the limits of this framework’s versatility.
• The regulatory lifecycle presents several opportunities for relationship-building and consultation. Meaningful engagement will be important for governing genetic pest control, in order to manage risks and promote trust.
