Chair, 2022 Programme Committee

On behalf of the Programme Committee, I would like to invite you to attend 54th Annual Symposium of the Society of Toxicology of Canada (STC) in our Nation’s capital, Ottawa. This is the first time since 2019 that we will be welcoming delegates and presenters in person. As we are still in the midst of the pandemic, we recognize that not all of our members may be able to attend the meeting in person, and therefore will be offering a hybrid model for this year’s meeting.

Our theme this year is “Environmental and lifestyle exposure to endocrine disrupting chemicals: from cells to society,” offering four scientific sessions focused on different aspects of endocrine disruption. The Programme Committee and the STC Board of Directors worked very hard to develop a program that includes presentations on mechanisms of toxicity of endocrine disrupting chemicals (EDCs) and more practical aspects of evaluating human health or environmental risk. Additionally, we are highlighting the impacts of EDCs on Indigenous health in an Indigenous-majority session, which will feature lectures from Indigenous community members and scientists.

I would like to thank our speakers, who will be joining us from Canada from coast-to-coast, Brazil, Denmark, and the United States, in advance for their time and commitment for preparing to speak at this year’s symposium.  This program promises to deliver important insights for all toxicologists.
