The purpose of the CSNS is to promote the acquisition, facilitate the dissemination, and encourage the utilization of knowledge in the science of nutrition. It does this by holding an annual meeting, generally as part of the Canadian Federation of Biological Societies annual meeting, at which members are able to:
- present their research results to their peers
- hear about the latest research data in the nutritional sciences
- participate in symposia with world renowned speakers
- interact socially and professionally with their colleagues from across Canada
- and find potential students or staff
The official journal of the CSNS is the Canadian Journal of Physiology and Pharmacology. This is a multidisciplinary interantional journal covering the fields of nutrition, toxicology, physiology, and pharmacology.
The Society also participates in science policy, including lobbying for increased research funding, nominating members to the various advisory boards and grant selection committees of granting bodies, advising government agencies on issues related to nutritional sciences, and keeping its members informed about important issues related research funding.
The Society also functions as the Canadian National Committee, which through partnership with the National Research Council, represents this country on the International Union of Nutritional Sciences. The CSNS recognizes excellence in and exceptional service to the nutritional sciences through its annual awards, the Centrum Foundation New Scientist Award (sponsored by the Centrum Foundation, the McHenry Award for Distinguished Service (sponsored by the Canadian Food Informational Council), and the Nestlé Nutrition Graduate Student Award (sponsored by Nestlé). There are three classes of membership, regular, student and emeritus. The Society is incorporated as a non-profit corporation that is governed by a constitution and set of by-laws. It is managed by an elected Board of Directors.
