So, I'm a Nikon guy, but I do like the JPGs that Canon cameras make. I like it much better than the Nikon JPGs. I thought that there must be a way to mimic the Canon JPGs with my D7000, and after fiddling with it for a while, I finally managed to get it right. It even got confirmed by a hardcore Canon user. She said "these really look like Canon JPGs" so there you go, there is evidence. I hardly ever shoot in JPG though, but it was fun to figure it out.
So the settings are in the SHOOTING MENU:
Set the white balance to Auto (the normal one) and then tweak it so it's Amber+1 and Magenta+3 (on the little grid the black dot is one right and three down)
Set the Picture Control to Neutral, and then tweak it so Sharpening is on 5, Contrast is -1, Brightness is 0, Saturation is +1 and Hue is 0.
Set Colour Space to Adobe RGB
and set Active D-Lighting to Auto.
This should give you Canon looking JPGs. Canikon JPGs. I'll post pictures when I have some that is worth showing.
