With the background of Mr. Daniel Edward Aykroyd (no spoilers!) and also as a Canadian... I trust that he wouldn't "BS" any of us for simply a paycheque. So.! If you would ever what to talk or listen to someone, about unexplainable occurrences, who are you gonna call?
Like most of these type of shows it does a wonderful job at peaking interest. Loose ends, open plots etc. What is true and what isn't? The answer is; you really do not know. Until someone factually, without a doubt proves any of the million mysteries or mysterious happenings that have apparently occurred since the existence of the universe... just enjoy the questionable.
