2026-11-19 CSEB StatsCan Webinar

This seminar introduces the Residential Mobility Exposome File (ReMEF), a newly developed analytical resource linking long-term residential postal code histories to multi-domain environmental exposures — air pollution, built and green space, and thermal stress — over up to 25 years, within the Canadian Census Health and Environment Cohort (CanCHEC).

The presentation begins with an overview of the file's construction and a snapshot of the cohort profile, highlighting its potential to support natural experiments that leverage residential mobility to examine cumulative, multi-domain exposures and disparities over time, including their relationship to population-level health outcomes. Two ongoing applications of the ReMEF will be presented.

The first, an environmental justice application, explores differential ambient air pollution exposure trajectories among racialized and non-racialized populations in Canada. The second, a core environmental epidemiology application, examines multi-domain environmental exposures and non-accidental mortality, using residential mobility as a quasi-experimental design.

Together, these applications illustrate the value of the ReMEF as a foundation for future collaborative research in environmental health disparities, exposure trajectory analysis, and mortality outcomes research.

Toyib Olaniyan is an Environmental Epidemiologist passionate about uncovering how our environments shape health, equity, and well-being. Currently, I work as a Research Analyst at Statistics Canada, where I analyze national health data to inform policies on environmental health and health equity. I also contribute globally as an Affiliate Professor at McGill University and an Honorary Research Associate at the University of Cape Town.

My journey has taken me across the UK, Canada, Nigeria, South Africa, and Switzerland, building expertise at the intersection of environmental epidemiology, equity, and justice. Alongside my research, I serve as Vice-President-elect of the Canadian Black Scientists Network, where I champion programs to elevate Black scientists, expand opportunities, and promote equity in STEM.

I am committed to using science, data, and collaboration not only to document disparities, but to drive systemic change—working toward environments where all communities can thrive.
