The Aquatic Toxicity Workshop (ATW) became a registered Canadian corporation in 1984, and is administered by a Board of Directors. The Board provides guidance on issues that may affect the future direction of the workshop series, and serves in an advisory capacity to the Organizing Committees.

ATW is held annually in a different region of Canada to draw interest among a wider group of ecotoxicologists and to gain a national perspective of current and emerging issues. These three-day workshops are traditionally held in the fall, where 200-400 participants take in over 100 platform and poster papers.

Each workshop is hosted by a local Organizing Committee on behalf on the Board. Workshops are organized on a two-year planning schedule, where arrangements for the date and location are finalized during the first year, and program and other details finalized the following year. Workshops are planned on a cost-recovery basis, with additional support from sponsorships.

The success of Workshops has largely been due to attendees who have generously contributed their time in serving in various capacities. Further information about forthcoming Workshops, and general information about the Workshop series may be obtained from those listed under Contacts.


When an individual registers and pays in full for ATW, he/she becomes a member for the period starting on the first day of the workshop for which he/she has registered and ending three weeks after the last day of the following workshop. This is typically a period of just over one year.

Members will have the right to vote on corporate resolutions and during elections.

Other than the full payment of registration fees, there are no dues payable to become a member of ATW.
