That's an interesting interpretation. In Canada, Charter free expression rights have been interpreted to include the right to access and read information, so censorship of foreign publications generally infringes the rights of Canadians who might wish to view them.

Of course I suppose that infringement is sometimes justifiable. Obviously free expression has limits and we do have probably-constitutional laws against foreign propaganda. But the government can't just ban a book because it was by a foreigner, thankfully.
