Many thanks to TheJuelzj for sharing their clip on youtube!
The Juelzj has posted a 7:16 min clip of Keanu Reeves signing autographs on the red carpet at TIFF 2013. You can clearly see Keanu during the first 1:30 min. After that, he has moved out of range and is not clearly seen while he continues to sign autographs. Apparently one of the fans was spushed while waiting for her autograph and you can hear Keanu ask her if she is alright. During the remainder of clip, you hear the chit chat of the fans.
The clip is here.
