It depends on what you mean by "canon". If you mean "official", then yes it's official Star Trek, as opposed to fan-made or whatever else. But if you mean "this movie's story takes place sometime after Enterprise and before TOS", then I don't think that's the case.
It seems like this movie is an entirely different universe/timeline/reality/storyline/divergence/whatever. At the end of the day, it appears to be a brand spanking new reboot.
I know what JJ and all them have been saying about timelines and all, but I think it's just lip service bologna to keep the Trek zealots from going crazy on the internet. I mean, c'mon, look at it. . . it's a reboot. The old has ended, something brand new is starting.
So it seems there's Trek Prime, and now NuTrek.
Well since it never happens can Paramount/CBS pay me back all the Money I've given them over my lifetime?
Sure.
Just send them back everything you've ever bought or watched and they'll see to it.
