We didn't do a cost analysis, but in the fall of 2013 the RCC secretariat in the Privy Council Office consulted stakeholders across a wide spectrum of industries. Based on the response of stakeholders on the popularity of the RCC alignment initiative, what they've been telling us is that to the extent we can align, that makes it easier for them to do business on both sides of the border.
Because the Canadian and U.S. economies are extremely integrated, any misalignment actually translates into costs, and as Mr. Ram said, that's passed on to consumers. If you have very high standards on both sides of the border but they're delivered more cheaply and more effectively, that's good for everyone.
