I did find a little information on the Canadian shortage from Health Canada and the Parkinson's Society. The situation in Canada seems somewhat different than what was reported in Europe and Australia, and it was predicted to be resolved sooner. But the fact that these announcements of shortages all were made around the same time is suspicious. Still no real answers. If you haven't already seen these web pages:
