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.

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 methodological rigour of its scientific assessments, EFSA sought to develop a standardised framework for problem formulation (PF) within its non-application scientific assessment protocols. The goal was to support the planning phase of these assessments by establishing a structured, reproducible approach for translating mandates into scientifically answerable questions. This included creating a framework…

Authorities in Vietnam sought targeted expertise to strengthen the country’s ability to detect, assess, and respond to food safety threats. This initiative had two linked objectives: building a comprehensive, transparent, and reliable national food safety information system, and enhancing risk assessment (RA) capacity at national and sub-national levels. For the information system component, the work…

The client sought support to finalize a Commission Member Document (CMD) for the re‑licensing of a nuclear facility. Recognizing the complexity and sensitivity of reactor re‑licensing, they requested assistance in crafting communication materials that were both technically comprehensive and accessible to regulatory bodies and broader audiences. The work included drafting a clear and well‑structured CMD,…

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.

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 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.
