If the light is in operation it is being manned. When I was there, the penny pinchers in Ottawa were promoting automated lights to cut costs. At that time, many lighthouses in the US had already been converted to automatic operations and as often is the case, Canada was following suit.
It was my duty station but I spent a lot of time at VTS.
I haven’t kept in touch with him but the assistant light keeper at the time wrote a book about lighthouse keepers in isolated areas who went bonkers from solitude (so they thought).
It turns out the skin in their hands was absorbing the mercury in which the lens apparatus floated . It turned out that hat makers suffered from the same affliction because they made the beaver hats shine by coating them with mercury which is highly poisonous. They became known as the proverbial Mad Hatters.
I can’t remember his name but he also wrote other books so you could probably google him.
