As @Rolls stated, West Pine and Duck N Run are on Crown land so the usual hunting rules/season apply. There is a long history of hunting by some local residents, but the amount of hunting has dropped a lot in the past 10 years.
Hunting is not permitted around any other sanctioned trails, because all the land from Clark Kent to the far end of Flat Lake is now HRM Park. Hopefully no-one is hunting 182m from the Osprey trail head!
As for the unsanctioned Bloodline, Gords and SSS trails (ie the area NW of Flat Lake), these are on private ‘forest land’. As Margareefisher states, hunting is permitted here given legal distances but hunters are encouraged to seek permission from landowners before entering private property, and modifying someone else’s property (blinds, etc) is not permitted. (see page 7 of the summary rules link https://novascotia.ca/natr/hunt/pdf/Hunting_Summary.pdf)
It is kind of complicated, isn’t it…
The new trailhead maps will clearly show the division of Park, Crown and private lands. These should be up before spring. Land ownership overlays can also be added to Trailforks, I think. Would that be helpful?
