According to Oda, it is canon. But how can a guy who managed to take on Sengoku and Garp, and seriusly injure them, lose to a pre Haki Luffy.
IMO shiki can be used or nother nteresting plot device, such as that he could kill Big Mom and take over her yonko status, and work with BB or even Enel and wreck havoc. This would have been a much better fight than the fodder Shiki vs Luffy.
