CBC News will livestream the Celebration of Life for Amanda Michelle Todd on Sunday, November 18, starting at 1:30 p.m. PT from the Red Robinson Theatre in Coquitlam, B.C.

Amanda Todd, a 15-year-old girl from Port Coquitlam, B.C., committed suicide in October after suffering through two years of cyberstalking, harassment, and bullying.

Just weeks before her death, Todd posted a poignant video to YouTube, in which she detailed her plight with bullies and others who tried to manipulate her in person and online.

In the video, using a series of flash cards, Amanda told the story of how she was stalked online and how a series of offline social betrayals left her feeling completely alone.

The video gained worldwide recognition after her suicide, and registered over 6 million hits. Copies of her video re-posted to YouTube have since gained at least 16 million additional hits.
