The YCJA Applies to Young Persons Ages 12 to 17 Inclusive
When you go to Court they will ask you for your date of birth.
Since the implementation of the Young Offenders Act in 1984 there has been a great deal of debate about whether Canada's young offenders legislation should apply below age 12 or only up to age 15. Children under age 12 are dealt with already under Ontario's Child and Family Services Act. Prior to 1985 adolescents who had reached their 16th birthday were dealt with as adults in Ontario even if they were considered juveniles up to and including age 17 in Quebec. The equality before the law provisions of the Charter of Rights put an end to that disparity in 1985.
The relevant date is the date of commission of offence. I have defended a "young person" in his mid-twenties charged with a serious offence allegedly committed at about age 15. He was successfully acquitted because of legislation changes over the years and because police had not complied with the rules for taking statements from young persons. The Crown labelled it the "forever young defence" and launched an appeal which was later abandoned. The case triggered an amendment to the YOA and ultimately the YCJA.
