Environmental Assessments at the CNSC
Environmental assessments are carried out under the Canadian Environmental Assessment Act. They identify whether a specific project is likely to cause significant environmental effects. Environmental assessments are carried out when any of the following conditions apply to a proposed project:
- federal, provincial or territorial government approval is needed;
- federal land is needed; or
- federal funding is needed.
For more information on the environmental assessment process, please refer to the Canadian Environmental Assessment Agency's web site at www.ceaa-acee.gc.ca.
You may also consult the
Fact Sheet on the
Environmental Assessment Process at the CNSC.

Amendments to the Canadian Environmental Assessment
Act
The Canadian Environmental Assessment Act was amended on October 30, 2003.
To view the news release,
click here.
The result of one of the amendments is the replacement of the Federal
Environmental Assessment Index (FEAI) with the Canadian Environmental Assessment
Registry (CEAR), a web-based registry showing information about all ongoing
environmental assessments, and listing documents relevant to those assessments.
The objectives of the new CEAR are improved public accessibility of EA
information; and the provision of timely notice to the public of the
commencement of EAs, and of the opportunities for public participation.
