[Iniquity]

Hey

So recently I found a post online that a small group is doing airsoft in in their own property like 70 acre big.

My concern is that

1. Are they legally allowed to play in their own property?
2. Majority of them are 16 so is that something to be concerned about
3. Do they have to get permission or notify the authorities to prevent issues

This is in Ontario.

Any feedback is greatly appreciated with source.

Thanks
