Like many other things, it depends on where you are. Also depends on whether or not it's Federal or Provincial Crown land.
In Ontario, there is a rule about access that another land owner cannot do anything about. I recall, when I was looking at buying tax sale land, it being a right of way that runs along the property lines. A road may or may not exist. They don't way up north. Way up being just about anywhere. Parry Sound area when I was looking. Anyway, as mentioned, talk to the local municipality office or MNR office.
A hunting licence does not grant you any special privileges to go on any land, anywhere. If you ignore a no trespass sign, you will eventually be fined. Trespass doesn't mean "do something wrong" either. Hunting is NOT legal justification. Read 3.(1) (e). No W's. nslegislature.ca/legc/statutes/protect.htm
Probably want to read this too. Add the W's. Go to the bottom of Page 3.
