In the changes as are stated here, the government's amendment to the coming into force, which is clause 85...this amendment we're making, which everyone received a copy of, was made so that subsections 38(1) and 38(2) would come into force on a day or days to be fixed by order of the Governor in Council. It's a very technical amendment, in other words.
On May 10th, 2012. See this statement in context.
