I live in canada, when I was much younger I got caught shoplifting twice, two separate incidences... the first, had no consequences, I was fingerprinted and all the jazz and taken into a room and qeustioned and then I went home and that was the end of it...

The second I had to do community service and go to therapy, and check in with what I think was a youth probation officer twice... but I never went to court or anything...

Will this be on my criminal record? Like if I get a new job and they do a check will this show up? It was before I was 18

If both were before you were 18, no, its your juvenile record and they can't see that in a normal background check.
