Abstract
Organized by the Environmental Health Association of Canada (EHAC-ASEC) and the Environmental Health Association of Quebec (ASEQ-EHAQ), Resilience: An International Conference on Multiple Chemical Sensitivity, a groundbreaking event, was held online over two days, on 1 and 2 May 2025, and brought together experts and stakeholders from multiple sectors to address a condition that has received limited attention in health, policy and research contexts. The conference convened leading international researchers, legal experts, medical professionals, policymakers, and advocates to examine one of the most pressing but under-represented public health and human rights challenges of our time. Multiple Chemical Sensitivity (MCS) is a disabling condition affecting a growing number of individuals globally. Despite its prevalence, MCS remains marginalized and under-recognized in healthcare systems, policy frameworks, and scientific discourse. The conference spanned 2 days, drew nearly 900 participants, and featured engaging presentations and discussions that integrated scientific evidence, lived experience, and cross-sector perspectives. A central theme emerged: recognition of MCS extends beyond medical considerations, encompassing accessibility, gender equity, environmental justice and human rights.
