Hello, don’t know if you got my PM, but you could use these maps from me and various other fellow enthusiasts.
You can use my map of American sirens not in the United States of America to take some locations:

I’d also recommend Emma Hones’ map of Canada as my map doesn’t fully cover Canada (if you aren’t using it already):

You should also check out some of gabetlamb’s siren maps for additional locations.
