The 2005 amendments were made on the basis of recommendations from the stem cell oversight committee and some recommendations from the CIHR governing council. They would then have been approved at the level of the governing council within CIHR. They then would have been taken to the other councils, NSERC and SSHRC, for their approval, because all the councils work together on that, and then they were announced in June of 2005. Shortly thereafter, Canada's first two stem cell lines were also announced.
On December 12th, 2006. See this statement in context.
