The Scugog bylaw declares "no person who is less than 18 years old shall possess a replica firearm or imitation firearm while on public property or on private property to which the public has general access." An imitation firearm is defined as "any device that is designed or intended to resemble a firearm or replica firearm or may be reasonably mistaken as a firearm."
This is the only bit out of the whole speil which is really worrisome to me. Pball places are private property generally accessible to the public. Under the current definition of the bylaw, we could be prosecuted for playing in pball arenas.
On the other hand, I'm not sure what the definition of "accessible to the public" means. Pball fields won't let people walk on without eye protection or signing a waiver and usually paying a fee. That is probably restricted access of some kind.
