I can only speak to my personal experience on that. I can tell you that I personally have phoned the RCMP for assistance on the river when I've been threatened. I have been told that they don't respond to elver calls. Nobody has shown up. At that point, the response for me, for safety in my workplace, is that I have to leave.
As a landowner who reports trespassing, I can also assure you that there's no response there either. I find it very hard to believe that there were only six reports for the year. I know landowners on rivers that we fish, and I can speak to their calling more than six times.
