A large number of domestic and foreign animal diseases with zoonotic health impacts to humans must be managed carefully to prevent disease transmission and spread. Risk management decisions often involve the comparison of different types of risk and the cost-effectiveness of different control measures for reducing risk. This requires that different types of risk be assessed in a consistent manner to allow cross-comparisons. The use of disability adjusted life years (DALYs) as a measure of the burden of human disease from domestic and foreign animal pathogens was completed for several zoonoses in Canada.

To support the Chemicals Management Plan under the Canadian Environmental Protection Act (CEPA), Health Canada sought expert peer consultation for a draft screening assessment report (DSAR) evaluating 47 inorganic substances identified as priorities. The client required independent scientific and technical expertise to assess whether the report’s conclusions—particularly regarding health effects, exposure pathways, and risk characterizations—were sound, complete, and defensible.

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.

To advance the Government of Canada’s Chemicals Management Plan (CMP), a virtual expert workshop was planned and hosted to refine and evaluate a Canadian framework for the Environmental Public Health Approach (EPHA) to chemicals. The initiative focused on developing case study models that could serve as a foundation for more comprehensive assessments linking chemical exposures…

To support more consistent and quantitative assessments of new micro-organisms under the Canadian Environmental Protection Act, Health Canada's New Substances Program (NSP) sought to refine the tools and processes within its Microbial Risk Assessment Framework (MRAF). The NSP had previously collaborated with RSI to review and modernize the MRAF and develop a supporting computational tool. However, further work was required to validate the tool and ensure it aligned with current program needs and regulatory expectations.

An international airport authority sought a comprehensive assessment of passenger and vehicle traffic flow after receiving complaints of confusion and safety concerns. Reports indicated that passengers were struggling to interpret signage, often stopping too long to process graphics, which caused line-ups and delays. Lighting problems compounded the issue, with signs placed in poorly illuminated areas.…

In response to increasing public concern about the historical use of McIntyre Powder—an aluminum-based substance once administered to miners in Ontario to prevent silicosis—the client sought expert guidance on managing risk communication related to potential health implications. Widespread media coverage and advocacy had raised public awareness and intensified scrutiny, particularly about possible links between aluminum exposure and long-term respiratory and neurological conditions.

The project centered on supporting the development of a methodology that could eventually be implemented as an Artificial Intelligence (AI) or Machine Learning (ML) process. The objective was to help formalize and potentially automate how professional judgment is applied when determining the risk significance of non-compliant findings within the Canadian nuclear regulatory framework. Specifically, the…

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.
