indepth - Just in case you have no idea about how the judicial or regulatory processes work, let me help you out. Lawyers for parties involved in proceedings, both in civil and criminal courts, and in regulatory proceedings, communicate as a matter of course with officials of whatever agencies they are dealing with, be it courts or regulatory commissions, regarding scheduling and cancellation or continuance of hearings. Therefore, it stands to reason that parties involved in these proceedings are told before a previously scheduled hearing date whether or not the hearing will go forward. It's not like they are required to travel all the way to Toronto and show up for a hearing where they are then told "Sorry, we decided to continue the hearing; too bad, so sad. See ya next time."
Now think about this very carefully, considering the individual and corporate parties which have been accused by the OSC and, just maybe, you'll be able to figure out who the "source close to the company" could be and why that source may have information about the hearing that has not been otherwise been made public.
Good luck! I know you can do it!
