Hey, I was curious if anyone has the sheet music for Canon Rock on violin?

I wouldn't go there. Canon Rock was written for Guitar. If you look for Violin or Cello, they will appear, but only at the Beginning or End because that's where the actual instruments debut

Actually, Canon Rock was transcribed for violin a couple months ago. If you go to http://www.freewebs.com/infinityex/ and look, you should find an intermediate version and an advanced version. It sounds exactly like this, with more added on at the end -->http://www.youtube.com/watch?v=huplhRTXGOc

you can also get it at

this joker dude did it on both the violin and guitar

It is playable on the violin and sounds fine, comes in intermediate and advance forms,
