Just read an interesting article stating that were U.S. copyright duration not extended an extra 20 years, many more works would now be in the public domain and orphan works legislation would be less important to those seeking use of still protected materials in the U.S.
In relation to Canada, with a duration of life + 50 and an unlocatable copyright owner provision -- does that mean Canada's copyright policy is good, or at least balanced policy? Of course, when Canadian works are used in the U.S., U.S. copyright law (life + 70 and no unlocatable copyright owner provision exists), the use of those works are subject to U.S. law (and of course vice versa.)
