Just to clarify, if you look at section 36 of the Customs Tariff—not the bill, but the Customs Tariff—it says that sections 32 to 35, which are with respect to the general preferential tariff, cease to have effect on June 30, 2014. As Mr. Beyea indicated, this bill would change that date to December 31, 2024, or on such earlier date that may be fixed by order of the Governor in Council. That is already in law.
On May 9th, 2013. See this statement in context.
