It is only going back a number of years that Canada Post began to take legal action against some of the companies involved in remail in Canada. The courts have found that, despite arguments to the contrary, outbound international mail was part of Canada Post's exclusive privilege as defined in the Canada Post Corporation Act.
So I don't believe that this change ne sert à rien. It will clarify that outbound international mail is not part of Canada Post's exclusive privilege, which is a view that had been held by many, for many years, before the court pronounced otherwise.
