What matters isn't what is or isn't "canon"; canon is "an in-universe description; it purports to decide what's true or not from the perspective of the fictional universe." What matters is that just as the comics are official material, so is the movie. And the wiki "[instead] describes works of fiction as they are presented." (both of those are direct quotes from the page I linked)

Though you do bring up an interesting point about Spike; I hadn't thought of that one. I suppose he might qualify, but I'm undecided as to what my opinion is (as of now) on that matter.
