This topic has been beaten to a foamed frenzy over and over in this forum.
The truth is, you can have lots of preditors or lots of game, but you can never, NEVER, have lots of both!!!!!!!!!!!!
The difference in B.C. is you can shoot them, we can not ! And we will probably never be able to! Here in Wy, with unregulated wolves, they are killing and eating calf elk and moose to the point that the ratio is about 5 calves per 100 cows, true fact! And you need about 25 calves to maintain the existing herds.
I have hunted in B.C. three times, on all three occasions the oufitter said, get a wolf tag, and if you see any don't stop shooting until they are all dead or you are out of ammunition. But with your government and the hassles at the boarder I will never go back, that being beside the point, even your outfitters hate wolves because they reduce big game populations. Common sense, which most pro wolf people lack, says, more wolves, more coyotes, more lions, less game!
So, in my Wyoming, conservative attitude and beliefs, screw the wolf and those that support them !
