Thank you.
CEAA currently focuses on assessment of biophysical effects and other directly related effects using the legal test of determining the significance of adverse environmental effects and identifying mitigation measures that reduce the effects below the significance level. I think some people feel that the significance test has been misused; and in the past, the environment committee has proposed a definition of significant that would make this test more objective and quantifiable and less subject to misuse.
I'm wondering, Dr. Sinclair, if you could comment on how you might define significant. From the things that have been suggested in the past, it's clearly a very difficult thing to define.
