This pictogram looks like an upturned fish on the shore next to a tree. If you see this sign on a chemical, it means that chemical is toxic to aquatic life. Of the nine Hazard Communication Standard/GHS signs, this is the only one that is optional, so you may not always see it on every chemical that is known to hurt fish or other aquatic life.

A clear warning sign right across the street from Parliament Hill in Ottawa, Canada

Most likely, erected following the Canada Freedom Convoy of early 2022, for I had never seen this sign before.

Thanks (naught) to a bunch of conspiracy theorists who ultimately gave reason for all Canadians and visitors to Canada, to not be able to enjoy Wellington Street facing Parliament Hill.

Actually, a visit to the hygenist. All handled very efficiently. Entrance and exit and waiting area all extremely well organised.
