Radio and communications tower lighting

I have twice asked the Canadian governmental agency this question. Ten years ago I was referred to pages of documents that were difficult to interpret. More recently, I never received a reply to my email. Perhaps someone here has the answer.

Out in the hamlet of Bethel in Port Colborne, Ontario there is a communication tower. The aircraft warning beacon on the top flashes a white-white-red sequence. It is the only tower in this area of the Niagara Peninsula that displays this pattern. Any other towers seem to be equipped with either a red or white beacon.

I first noticed the white-white-red sequence when flying out west for work in Saskatchewan back in 2014-15. Very easy to spot from a plane at night. I have never noticed this lighting arrangement on towers in the U.S., but I haven't been over there for a couple of years.

Is this pattern a visual aid for pilots, or does the sequence of lights have a different meaning?

Thank you for any insight the group might share. I am posting in the Canada folder, since I have only noted the lighting sequence in Canada. I know there are some industry professionals who frequent the board, and might know.

You may want to post this in the engineering forum. Maybe someone there is familiar with Canadian rules.
