(29) No person shall ride a bicycle across a roadway within or along a crosswalk at an intersection or at a location other than an intersection which location is controlled by a traffic control signal system. R.S.O. 1990, c. H.8, s. 144 (29).
Second (assuming that the cyclist was in the crosswalk), you still have a problem. Replace cyclist with pedestrian and you clearly failed to exhibit complete situational awareness. Suppose someone were running across the road instead of cycling. You still need eyes on the crosswalk that you're about to drive across. The car turning right does not automatically have the right of way. So perhaps the kid could be charged with violating the section listed above. But you still have to yield to bikes, runners, walkers, dogs, cats and turtles in that crosswalk. I really don't want to be confrontational, so don't answer if you don't want to, but how did you not see the kid?
Not to be morbid, but here is an example of why everyone needs to pay attention to the crosswalk on the right. http://www.durhamregion.com/news-story/ ... ump-truck/
