Isn't the play written by JK Rowling? You know, the author of the Harry Potter books and therefore the word of god on how the charcaters turned out after a decade or so has passed since Voldemort's death?

So....it's absolutely canon. Your hatred of it is irrelevant, the play and its events are as canon as they're gonna get.
