Hi, I've been fortunate to hunt often in the 100 Mile House area of B.C.. Yes, guides are necessary for big game. The guide in that case will give you a letter to assist you in getting through Canadian Customs. Before you exit the U.S., stop by U.S. Customs and "register" your weapons and expensive gear (binocs, camera's, etc), so when you re-enter the U.S. you have proof that they belong to you, to avoid U.S. duty fee's. The "registration" is a one-page form that will be stamped, and you keep it. No "Page two" (big-brother stuff). As mentioned, HANGUNS/BEAR SPRAY not allowed. RIfles need a minimum barrel of 18", vs 16 in U.S. You do not need a guide for small game/waterfowl. Some years the grouse is fantastic, and the rabbit/hare bag limit is very generous, but I have seen only a few in my travels. Lots of coyote's available. Lets see...U.S. auto ins. is recognized there, but they have a minimum liatility coverage higher then the minimum in some states, I think they require 50K or 100K. Use plastic for the best exchange rates, but I carry Canadian cash, which I get at a bank where I cross. You'll need a passport to re-enter U.S. Bringing game back should be no problem, but check with U.S. Customs as you leave the states about what you hope to bring back, and talk to Canadain Customs as you enter and check with them also. In the past, with Chronic Wasting/Mad Cow scare, there was a time when no spine/brain could be brought back, and if meat was processed in Canada, a certificate from butcher shop stating no beef in 'burger and/or sausage was added. This may have been changed, but check ahead. If you scroll down to the "Hunting in Canada" forums I have soom responses there also that may have more info for you. Feel free to pm me with any specific question. Good luck. Mark.
