The Youth Extra Judicial Sanctions is essentially the same as the Alternative Measures Program, but is designed specifically for young offenders (person’s accused of an offence who are under 18 years of age).
The legislation that governs this procedure the Youth Criminal Justice Act. Typically, the Crown Prosecutors will have more latitude to divert matters into the Extra Judicial Sanctions Program because the main goal in dealing with young offenders is rehabilitation, rather than punishment. The conditions of the Extra Judicial Sanctions may include things like an apology letter, or an essay about the harm caused.
As with the Alternative Measures Program, the discretion to divert you into the program lies with the Crown, so it is important to get legal advise to make sure you put forth all relevant information to give you the best chance possible of entering the program.
