Mr. Speaker, there was a lot of due diligence done to determine exactly what should be done in amending the act and making it constitutional. We know the government always takes great measures to ensure the constitutionality of all its acts. Therefore, the time it took was attributable to the fact that we wanted to ensure all constitutional requirements were met and that we could make the best amendments possible to ensure we protect the rights of private citizens.
In the House of Commons on March 18th, 2013. See this statement in context.
