It could show up in your FBI file. A crime, even a felony that's adjudicated in a juvenile court is not considered when determining whether or not to pass you on a CHRC. If it does show though, the company considering you may apply a stricter standard if they see there was an arrest. More importantly, there is such a premium placed on honesty and integrity, if you are asked if you have been arrested and you say no, then an arrest record appears on your CHRC, I can guarantee you won't be hired.
It's better to tell them that you had a youthful indiscretion, error in judgement, etc and explain that you learned from it and have matured since then, etc. You'll probably get poins for honesty and owning up to what you did, which was not that serious.
Best of luck,
