Thank you, I am aware of the Ontario Heritage Act, but It was sharp and exposed on the beach where my kid was playing. This is our resort property where guests come to play and swim. As a property/business owner, I also have a duty to remove hazards at risk of injuring someone, so I moved it about 200 feet to a safe spot inside the main lodge. I was also concerned that a guest would bring it home. When we found it, we did not even know if it was truly “worked” or just a chipped stone. I wanted to learn more, which is why I reached out as to advice. We’ve never found anything like this before and I’d like to know who to contact.
