Participants include students, academics, government scientists and regulators, environmental consultants and industry representatives. For more information about the CEW, see About.

Accepting Professional Development Short Course Proposals

The 44th Annual Canadian Ecotoxicity Workshop (CEW) will be held at the Delta Hotel in Guelph, Ontario, from October 1st to 4th, 2017.  This year’s theme is ‘From Land to Lakes: Integrative Ecotoxicology in the Great Lakes Basin and Beyond’.  We are inviting proposals for professional development short courses in the areas of terrestrial and aquatic ecotoxicology, including human health.

If you are interested in leading a professional development short course that fits within the scope of CEW, please submit a brief (up to 500 words) proposal for a course that includes:

1) the course title,

2) the proposed course content, and

3) the expertise of the instructor (and co-instructors if applicable).

Please identify whether this:

  1. A) is a full (6 h) or half (3 h) day course,
  2. B) anticipated maximum and minimum enrolment numbers, and
  3. C) any special space and/or equipment needs.

Courses are expected to be, at a minimum, revenue-neutral such that any costs incurred in course delivery will be offset by participant registration fees.

Proposals must be submitted to the CEW 2017 Professional Development Courses Committee (via email to by April 30th, 2017. The Committee will evaluate course proposals on the basis of suitability to the meeting theme, potential interest, and anticipated costs. Final decisions will be made by May 30th, 2017. All courses must be delivered on Sunday, October 1st, 2017.
