I don't think there is one as you will infinity focus. Flange focal lenght is shorter on Nikon. You can go the other way i.e. use Nikon glass on Canon. Most modern Nikon lenses G won't usually work as there is no way to control aperture. Some folks use the 14-24 on Canon with a very special adapter. But I have never seen a Canon to Nikon adapter.
Novoflex has a Nikon G to Canon EF adapter. It's supposed to work with all G-type lenses. But even then, you have to do a bit of McGuyvering with the lens to remove some of the weather sealing.
