As far as I know, it’s illegal to harass anyone who is legally engaged in the sport of hunting or fishing. Like the others said, report them.
Section 13 of the provincial Fish and Wildlife Conservation Act clearly states that it is illegal to obstruct or interfere with lawful fishing, hunting and trapping
Obstruction of hunting, trapping or fishing
13 (1) A person shall not interfere with lawful hunting, trapping or fishing by,
(a) tampering with traps, nets, bait, firearms or any other thing used for hunting, trapping or fishing;
(b) placing himself or herself in a position, for the purpose of interfering, that hinders or prevents hunting, trapping or fishing; or
(c) engaging in an activity, for the purpose of interfering, that disturbs or is likely to disturb wildlife or fish.
