Is Naruto canceled from Cartoon Natwork?

No, Naruto is not cancelled from Cartoon Network. It's still ongoing and it only shows on Saturdays. The reason why it doesn't show much is because of the movies. They also show naruto movies too. Naruto is supposed to either come on 9:00 or 9:30 after they show the movies.
Hope this helps alot!

Naruto is still on, there just temporarily losing audience members due to the slow boring missions. This should stop soon when shippuden begins.

or you could just skip the crap and watch it all free online @ ovguide.com

No, it isn't cancelled. You can watch it on saturdays at 9:00 PM. Although the episode series is soo behind. Like right now there are already done with episode 172. Now they are on episode 173. Although there is a website where you can watch the naruto episodes. Its www.naruto-episode.net

Nope its still on there.

No.

I don't think so i think that they are like getting prepare so that they can get the right voices for Naruto shippuden.

Naruto isn't canceled, and neither is Toonami. They just changed Toonami. Naruto still airs on t.v on Saturdays, only. If you can't watch it on t.v, then try watching it online, It will often work well.

Hope that helps! ^^
