As a former graduate from the conservation enforcement program at LCC and worked in the field for a few seasons, like everyone says, just because you don't see them, they are around. I had the pleasure of working one of my seasons as a STEP officer in Calgary and trust me, these guys want nothing more than to get out in the field and catch people angling illegally. There is just a ton of other things to do also that do not include checking anglers. I was told the exact same thing by the senior officers that the folks here are saying, if a guy has about $500 worth of equipment on him, he probably buys his license. Chances are if you are near to a spot that F&W park their vehicle they may check you if it's a slow day, and if your a bit of a walk they won't bother and they'll go looking for the fellow with the $20 Mohawk rod and reel sitting on his case of beer. One fellow we watch for about 20 mins from the top of Bearspaw dam used his rod and his three daughters was doing pretty good below us until we confronted him. He denied it until we showed him the notes and where we were watching from. He got a fine.
