Validation and Optimization of the Computational Tool for the Microbial Risk Assessment Framework (MRAF)

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.

Food Inspection Scientific Analysis & Risk Modelling

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.

Risk Communication on McIntyre Powder

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.

Risk-Based Decision Making (RBDM) Compliance and Enforcement

Innovation, Science and Economic Development Canada (ISED), through its Spectrum Management Innovation Directorate, sought support in applying risk-based decision making (RBDM) across its compliance and enforcement responsibilities. The department was looking for a structured and data-driven approach to prioritize regulatory actions in a way that reflects risks to the public interest.

Methodology for Developing Risk Significance Insights

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…

Applying New Assessment Methods (NAMs) for Assessing Semi-Volatile Organic Compounds (SVOCs) in Indoor Residential Environments

Health Canada sought expert support in advancing its efforts to develop screening values for semi-volatile organic compounds (SVOCs) commonly found in residential indoor environments. Previous work on indoor air contaminants had focused on volatile organic compounds (VOCs), where screening values were developed based on existing inhalation quantitative hazard assessments (QHAs). However, many SVOCs were identified as having insufficient data to establish such values, leaving critical gaps in risk evaluation.

Airport traffic flow and signage review

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.…

Measuring impact of zoonotic animal diseases in Canada

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.
