Formerly known as the Aquatic Toxicity Workshop (ATW), CEW is Canada’s predominant annual meeting in the field of ecological toxicology and related disciplines.  It provides the opportunity to share information on current and emerging topics of regional, national and international importance related to contaminants in ecosystems, both aquatic and terrestrial. Participants include students, academics, government scientists and regulators, environmental consultants and industry representatives. For more information about the CEW, see About.

CEW 2018 – Vancouver, BC

Sept. 30 – Oct. 3, 2018

Location: Sheraton Wall Centre

Theme:  Science. Application. Action.

This theme reflects the work that each of our dedicated members undertake to maintain our natural ecosystems in a world faced with growing human demands for food, water, land, energy and other products.  Year after year, this workshop brings together representatives from all sectors so that we can share and collaborate to produce science that can be applied, and action can be taken to mitigate the adverse effects of pollutants on our ecosystems.   We are looking forward to hosting the workshop and carrying on this tradition with our fellow Canadian scientists and experts and progressing the field of ecotoxicology, and ultimately, contribute to preserving the natural environment we all cherish.
