I think I can speak to that on two points. There were the 2002 guidelines that came out. The guidelines were updated in 2005. They were also updated in 2006. In 2006, they returned to some of the text of 2002 and explicitly acknowledged that it is because it is a 2002 guideline that it had been incorporated into legislation. So there is a recognition on their part that at least some of the changes they tried to introduce would not be consistent with what would be required legally. So there have been changes in both directions.
On the point you're making with respect to fresh and frozen, there is, in my view, now an inconsistency that has been introduced into the CIHR guidelines. They still require a reiterated consent, which doesn't make sense in the context of taking fresh embryos. I've also suggested that there's data from other countries suggesting that there is no obvious reason to do that, and I have other documentation here that shows it's actually harmful to women to have made this change. I'm actually disappointed in the change, but there is no course of law for it.
