Ile St. Helene, Montreal

We were actually on Ile St. Helene in the middle of the St. Lawrence River but were too busy trying to find a parking spot to notice this strangely shaped oddity of a light. This photo was actually taken from the harbour area of Montreal looking across the St. Lawrence.
Some photos have shown this light in a bad state of repair but it seems newly painted, so maybe it is finally receiving some TLC. I am not sure if the=is was ever a "light," in the strict sense of the word, or merely a day-mark.
