The footage outside a convenience store shows the teen in a heated confrontation with a 46-year-old man who is struck with the board.
Michael Forry told a sentencing hearing that he suffered a severe brain injury and that 49 screws and 52 staples were needed to put his skull back together after the incident a year ago.
Outside court, Forry said he hadn't seen the video until Thursday.
"I'd never seen it so that was tough. It's hard to see yourself almost killed."
Forry said that while he wants justice for his attacker, he's no longer seeking vengeance.
"When I first started with this I was kind of aggressive about it. I wanted to see him jailed and come out in a body bag. As I got help myself from GF Strong I changed," he said of the rehabilitation centre in Vancouver.
Crown lawyer Frank Caputo said the violent offence calls for a two-month jail sentence in open custody at the Victoria Youth Custody Centre, followed by one month of community supervision.
Defence lawyer Tom Weiss said probation would be more suitable for the teen who is dealing with anger issues from a tragic upbringing and his complex psychological makeup. (CHNL, CFJC)
