Chair, given the time we are today—and it's obvious that this bill will not receive royal assent by June 30—it only makes sense that the Governor in Council set the date and not cause confusion around Parliament backdating this law. It causes confusion otherwise, contrary to what Mr. Spengemann may have just indicated. In my opinion, without a prescribed date, it actually causes more confusion by setting a date of something that hasn't even started to come into law yet.
On June 5th, 2018. See this statement in context.
