Guidance for Evaluating Human Health Effects in Impact Assessment: AIR QUALITY

This Health Canada guidance provides a framework for assessing the potential human health effects of air quality within federal impact assessments for major resource and infrastructure projects. It outlines the principles, methodologies, and information expected by Health Canada when reviewing impact statements, helping proponents evaluate how project-related air emissions may affect nearby populations. The guidance covers key components of the assessment process, including baseline air quality characterization, exposure assessment, identification of sensitive populations, health risk assessment, and the evaluation of mitigation measures.

The document is intended for project proponents, environmental consultants, regulators, and public health practitioners involved in impact assessment. By promoting a consistent and scientifically robust approach to evaluating health risks from air pollution, it supports evidence-based decision-making and helps ensure that potential health impacts are identified, assessed, and addressed throughout the project planning and approval process. The guidance is applicable across a range of sectors, including mining, transportation, energy, and other large-scale infrastructure developments.
