This paper would receive a "C" in first year poly-sci, as there is precious little in the paper that indicates that Canada has changed in that period...

On the other hand, what would a time traveler from that era find? That Canada has a Liberal government that is focused on soft social issues and deficit spending headed by someone named Trudeau?

Perhaps it is an "A' paper after all, as nothing in Canada has changed.
