Hello,
I have created a map of CD sirens located in Ontario, Canada. The map displays the locations of sirens that were present in the past, as well as some that are still present today. Initially, these CD sirens were included in the Ontario Siren Map, but after giving it some thought, I decided to create a separate map for them. This was done to make the Ontario Siren Map less cluttered and reduce the possibility of it lagging.
