Environment and Climate Change Canada, with Health Canada, wanted to understand perceptions of the health risks from smoke from wildfires and from residential burning (winter heating using wood stoves, and fireplaces), and public health communication approaches and messages used in these contexts. This information would support revisions of the health messages used in the Air Quality Health Index (AQHI). The AQHI expresses the health risk associated with three common urban air pollutants, and is calculated at monitoring stations in communities across Canada to inform the public of the risk level of current local air quality conditions.

To support regulatory decision-making, a comprehensive risk assessment was conducted to evaluate how varying lethality performance standards would impact the public health burden of salmonellosis associated with Ready-to-Eat (RTE) meat and poultry products. The primary objective was to quantify the expected number of cases of illness under different reductions in Salmonella presence across a broad spectrum of RTE product categories.

Following the planned closure of the Blood Safety Contribution Program (BSCP), support was needed to help define the structure, elements, and functions of a renewed national recipient hemovigilance system for Canada. The work centred on preparing the transfusion medicine community, federal and provincial/territorial partners, blood operators, and patient representatives to develop recommendations for a future system that could maintain national coordination, support blood and patient safety, and preserve trust in Canada’s blood system.

In response to public and ministerial concerns about the timeliness and adequacy of information shared during a major prescription drug recall, Health Canada commissioned an independent review to assess its response to the event. The situation involved a recall of the oral contraceptive Alysena, issued due to packaging issues that altered the intended dosing sequence and raised questions about potential unintended health risks.

To support the evaluation of a new veterinary pharmaceutical product intended for use in bovines, a scientific review was requested of submitted toxicological data related to the active compound LY488756. This compound, proposed under the product name Experior, had been advanced for registration based on its claimed selective action on β3-adrenergic receptors and a lack of mutagenic, carcinogenic, or teratogenic effects. Given its potential entry into the human food supply via meat residues, an independent expert analysis of the submission was deemed necessary to determine its safety.

A comprehensive systematic review was undertaken to assess experimental evidence regarding the potential health risks associated with artificial sweeteners, specifically focusing on cancer and pre-term delivery. The client sought a rigorous analysis of both in vivo and in vitro experimental studies to better understand any biological associations or mechanisms that might underpin observed health outcomes.

To enhance the oversight of cannabis production under its regulatory mandate, the Cannabis Directorate sought expert support in developing a risk-based decision-making framework tailored to its compliance and enforcement responsibilities. The directorate aimed to better assess and respond to non-conformance with Good Production Practices (GPP) as defined in the Cannabis Act and Regulations, using a data-driven approach.

In support of ongoing efforts to modernize Canada's food inspection system, a request was issued for scientific and analytical expertise to enhance two critical risk-based decision tools: the Establishment-based Risk Assessment (ERA) and Importer Risk Assessment (IRA) models. These models are used to allocate inspection resources across food establishments, importers, hatcheries, feed mills, and renderers in a structured and scientifically defensible manner.

To support the refinement and implementation of its ecological risk guidance, a federal department responsible for marine conservation engaged expert assistance in risk communication. The primary objective was to ensure that the national guidance for ecological risk assessment—developed as part of the department’s marine spatial planning and marine protected areas initiatives—could be effectively communicated to diverse internal and external audiences.
