That 50. 00 crazy horse mentioned is Canadian funds. It works out to be about 30-35 US. You only pay one fee per person so you can take more than one gun and it is still only 50. 00 canadian. If you contact the Canadian government and register the guns to be transported then you can get a 5 year permit for 80. 00 Canadian, the only downside to this is it needs to be done several months before hand. You can do the 50. 00/1 year permit at the border crossing.
The last time I check into hunting in BC you had to have a guide to hunt as wyosteve mentioned. If you have ever driven to Alaska you realize the diversity of game that BC has, the only downside is the guide requirement. The Yukon also has some impressive muledeer, whitetails and elk (as seen in the headlights along the Alcan Hwy). The last I checked BC has 4 types of deer, 2 types of elk, 2 types of moose, 2 types of sheep, 2 types of bear, wolves, mountain lions, and goats.
