21st Laurentian SETAC Annual General Meeting & Conference

Laurentian SETAC (L-SETAC) held our 21st Annual General Meeting and Conference at the University of Waterloo on June 23-24, 2016. The theme of the meeting, Watershed Science Under Multiple Stressors proved to be a great success! Continuing with tradition, we kicked-off the meeting with a pre-AGM short course. The course – Data Quality & Weight of Evidence: Making Your Toxicology Matter – was derived from the outcomes and recommendations of the SETAC Pellston Workshop conducted in Fall 2015 on “Improving the Usability of Ecotoxicology Data in Risk Assessment”. Instructors Drs. Mark Hanson (University of Manitoba), Keith Solomon, and Glen Van Der Kraak (University of Guelph) put together an informative and engaging course that received rave reviews from participants.

Our three plenary speakers, Dr. Deb MacLatchy (Wilfrid Laurier University), Dr. Neil Hutchinson (Hutchinson Environmental Sciences Ltd.) and Dr. Patricia Chambers (Environment and Climate Change Canada), inspired an audience of more than 100 attendees with their interesting and insightful talks. For the General Meeting portion of the day, L-SETAC President, Ryan Prosser and Treasurer, Ève Gilroy, provided an update of SETAC’s activities over the past year. A number of special presentations and exciting announcements were also made at the meeting. Highlights included: • Introduction of the new Maria Colavecchia-Pfuetzner Memorial Travel Awards and a one-time donation to the education fund for her daughter, Natalie Pfuetzner, in memory of L-SETAC member and friend Maria Colavecchia-Pfuetzner. • Announcement and launch of the L-SETAC Women in Science Committee. • We acknowledged three retiring Board members – Joel Nichols, Alison Fraser, and Ève Gilroy – and thanked them for their commitment to L-SETAC. • A new L-SETAC award was announced and presented to four members in recognition of their long-standing and significant contributions to the chapter. Congratulations to Natalie Feisthauer, Alison Fraser, Ryan Prosser, and Ève Gilroy on receiving the Laurentian Chapter of SETAC Outstanding Service Award! • Ryan Prosser officially handed the reins over to Rick Frank who will be taking over as L-SETAC president for 2016-2017.

In addition to the plenary presentations, we had 20 platform and 21 poster presentations spanning a wide range of topics related to environmental toxicology and chemistry, reflecting the diversity of our tripartite (academia, government and industry) membership. Presenters included students from seven universities across Ontario (University of Waterloo, Wilfrid Laurier University, McMaster University, University of Guelph, Ryerson University, University of Toronto, and University of Ottawa).
