As @Bentley pointed out, Canada has already processed the CITES exemption for musical instruments. However, I'm pretty sure that this is only because our economy is so closely tied to the United States. I'm sure that Warmoth is right about there being no problem with shipments exiting the U.S., but as others have pointed out, it's still buyer beware on the import end. It was there that things went off the rails with the first CITES confiscations. It also occurs to me that America's changing profile on the world stage might be a factor overseas. With all the fuss over new tariffs on steel, automobiles, etc., other trading partners may not be in a rush to update their legislation.
