Again, I'm not sure if Health Canada should do the study. Health Canada would certainly be interested in such a study, and helping with it.
I don't think...I said the studies to date may ensure that our Safety Code 6, we believe, is accurate and shouldn't be changed. We review the Safety Code 6 standards regularly to update them and we reissued it again in 2009. So certainly I don't want any member of the committee to believe that it's set in stone. We continuously review the literature and would change it as imposed by...as another member of the committee suggested about changing guidelines. We do change guidelines based on new information.
