I think the United States has made some progress. Another example would be the United Kingdom, where they have looked at harmonization initiatives.
One thing in particular that the U.S. has done through their Office of Regulatory Affairs is that they've launched a whole website that looks at different resources and different regulations between different states and are building that as a kind of concierge service to coordinate harmonization in regulatory activities.
I think that would go a long way, as a public tool, to helping the public understand what's there between different states, as well as helping government to understand that “here are the barriers to growth and here's where there are opportunities to harmonize”. You could even have Canadians or officials from other governments being able to submit those harmonization opportunities through a portal.
