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.

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.

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.…

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.

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.

The project began with a series of consultations with UN-Habitat at UNON in Nairobi. In addition to Cemil Alyanak and Nicholas you, the project grew to include many key stakeholders both within UN-Habitat and from other organizations. Among the key organizations included in the early stages were United Cities and Local Governments, Cities Alliance, the World Bank, Habitat for Humanity, Cisco, and UN agencies interested in urban health, notably the World Health Organization.

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.

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.

An independent regulatory organization responsible for oversight of Alberta’s safety codes system sought to strengthen its capacity for risk-based decision-making. The organization aimed to ensure that regulatory actions—particularly in the area of petroleum storage tanks—were guided by clear, evidence-based prioritization methods that protect public safety while making effective use of resources. The project began with…
