Thanks Rodney for the clarification. I by no means try to attack flyfishermen. I am one of them. I have tied hundreds of flies and used them in lakes for trout, salmon like coho, pinks, chums, even springs (at the Big Qualicum). By May I may hop out for the Vedder steelhead with my 9 wt. I am not anti flyfishing. I am only addressing my concern for those Lafarge shore flyfishermen whose backcasts can harm innocent and unsuspecting pedestrians. Yes, nothing may happen. Accidents don't happen all the time, but we know they do happen, and the higher the probability, the more likely it will happen.
When something bad happen, as Rodney suggests, sport fishing can be shut down to prevent further happenings. We are just a minority user group compared to those joggers and walkers who stream through those walkways all day. So if our action proves to be a risk to the majority, then we will be shut down. Why wait till it happens to do something. It will be too late. As Rodney puts it, city can be sued too and they won't want such liability.
If you don't believe what goverment authority will do when something bad happens in fishing, just watch the closure of the meat hole above Stamp Falls. Years back, that spot was filled with fishermen targeting the plentiful springs of the Stamp River. People would line up shoulder to shouder and fish were hooked left & right. Lines crossed, fish lost, arguments erupted, and finally somebody knifed somebody else. After that, closure. I have no idea if it is still closed. But this goes to say, even if fights happen among fishermen and not innocent bystanders, the end result is the same - closure.
So let's do the right thing, to make sure your fishing activity is safe for yourself and for other user groups too. Then we will not have to regret when they stop stocking the lake.
