A federal agency required scientific support to enhance the effectiveness of its environmental enforcement activities. This involved identifying and analyzing the risk factors—both environmental and human health-related—that contribute to the likelihood and impact of regulatory offences. The objective was to develop a structured approach to prioritize enforcement actions under key legislative frameworks including the Canadian Environmental Protection Act, the Fisheries Act, the Species at Risk Act, and others.

RSI integrates benchmark dose modeling into risk assessments involving chemicals, environmental contaminants, or pharmaceuticals. Its toxicologists and statisticians apply international modeling tools with a focus on model selection transparency, biological plausibility, and sensitivity analyses. RSI helps clients use BMD outputs to derive actionable guidance values while also preparing summaries that facilitate stakeholder or regulatory engagement. The method is embedded in RSI’s broader approach to data-driven toxicological assessment.

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.

Public transport systems are critical to economic productivity, urban mobility, and environmental sustainability, but they also present complex safety, health, and operational risks. Accidents, infrastructure failures, overcrowding, and infectious disease transmission all pose potential threats to passenger safety and public trust. Meanwhile, climate change adds further stress, with extreme weather events disrupting services and damaging…

CCHIP is a web-based tool that uses data from 40 of the most recent Global Climate Models (GCMs) and many other sources, to provide defensible, actionable conclusions about changes across a whole array of climate and severe weather-related conditions.

RSI supports the development of learning health systems by linking data infrastructure, outcome measurement, and governance. The firm applies its expertise in surveillance, feedback mechanisms, and stakeholder engagement to ensure the system evolves with evidence and remains centered on patient or population benefit.

Working with international thought leaders in risk science, Risk Sciences International investigators contributed to the development of the evidenced-based risk assessment framework shown in the figure below.  The framework evolved from a workshop held at the University of Ottawa in December 2018, jointly organized by the McLaughlin Centre for Population Health Risk Assessment at the University of…

RSI supports rare event modeling through structured scenario development and probabilistic modeling. Its interdisciplinary team helps clients quantify uncertainty, stress-test assumptions, and prepare for high-consequence possibilities. RSI presents rare event outputs with clear framing, enabling proactive planning without overstating precision.

As a Microbiologist with Risk Sciences International, Dr. Sattar contributes his deep expertise in pathogen ecology, environmental microbiology, and infection control technologies to support RSI’s work in health risk assessment and risk mitigation. His insights guide RSI’s contributions to evidence-based disinfection strategies, microbial exposure modelling, and policy-relevant evaluations of infectious disease risk across water, air, food, and surface-contact pathways.

Effective and coherent risk management policies and regulatory oversight processes are essential for an agency's efficient and consistent decision-making, and reinforce public confidence in the performance of their mandate.
