You would be mistaken if you thought that this was Denis Forristal doing his warm up dives before staring the day's work at the Bayshore.
In fact, this is Pierre Elliott Trudeau, then Prime Minister of Canada, who enjoyed a morning dip while staying at the hotel. He once remarked to Denis that is was his favorite hotel pool.
Denis was never able to score the Prime Minster any higher than a 2 on his diving!
