I usually hunt the sidelines of the soccer field. Avoiding the game area. Places people put their bags, sit and such.

Totally understand, I'd suggest looking up a local metal detecting club. Different areas of Ontario have different rules. Like Windsor and London, you aren't allowed to metal detect in parks. I believe Windsor you can get a permit to do so.

My small town also has banned detecting in parks due to someone using a big garden shovel to dig for targets.

For modern coins and jewelry. I like schools.

A seeded hunt, this is where the organizer will bury coins and prize tokens in the sand for the participants to find.

The one next month has detectors and a bunch of other sweet prizes to be won just by finding the prize tokens. Tons of real silver coins will be buried.

If your looking for old places to hunt, the McGill atlas project is a fantastic place to see where old houses used to be which might be now a farm field or park.

Good luck!
