What is sort of funny where I live is that there is Georgian Bay, all sorts of natural lakes and ponds and rivers everywhere. Many farms have either natural ponds or dug ponds.
Just the same there all sorts of regulations and fences with locked gates required for anyone who puts in a swimming pool.
The people next door might have a 5 or 6 foot deep fish pond but that is ok without fencing.
Politicians with too much time on their hands.
