Madam Speaker, the provisions in this bill were actually changed, under section 44 of the Constitution, which is within the authority of Parliament to do. This has been done in the past. In the late 1980s, Parliament changed the number of seats in the House of Commons through section 44. So it is within Parliament's authority to change the Constitution to bring under-represented provinces closer to representation by population.
In the House of Commons on November 3rd, 2011. See this statement in context.
