Producers will not have access to strychnine for Richardson’s ground squirrel control in 2026, after Health Canada’s Pest Management Regulatory Agency (PMRA) denied a joint emergency use request from Alberta and Saskatchewan.
The request was submitted in response to increasing ground squirrel populations and concerns about damage to pasture, hay land and crops. Producers and provincial officials argued that existing control options are limited and often less effective during high-pressure years. Alberta Beef Producers (ABP) participated in the emergency use request process by supporting the Provinces’s request by submitting letters of support outlining on-the-ground producer concerns.
In its decision, the PMRA cited safety and environmental concerns associated with strychnine. The agency pointed to potential risks to human health, non-target wildlife and the broader environment. (Read the full PMRA final decision “Information Note” here.)
Emergency use requests are intended for exceptional circumstances and must demonstrate that risks can be effectively managed. The PMRA concluded that the proposed mitigation measures did not sufficiently address those risks, and the request was denied for the upcoming season.
Alberta Agriculture and farm groups have highlighted the ongoing challenges ground squirrels pose, particularly on pasture and hay land where burrowing activity can reduce productivity, damage equipment and create safety concerns for livestock.
With the decision now final for 2026, producers will need to continue relying on currently registered pest management tools for ground squirrel control. Alberta Agriculture has indicated it will continue working with producers to explore available options and will remain engaged with federal regulators on longer-term solutions.
ABP will continue to monitor this issue and share updates as they become available. Producers are encouraged to speak with their municipalities about appropriate ground squirrel control options for their operations.
