It's all canonical. As the anime, unlike the film, doesn't differ enough to really be considered something other, imo. I don't condone spoiling, nor do I really support the idea of bringing up scenes that the anime-exclusive viewer will never see, but to bar manga speak, and potentially interesting conversation on narrative as a whole because 'the anime will never get there' is but setting arbitrary, almost-childlike restrictions, imo. I brought up the conversation that was had on Chihaya few paged back in my last post as the example of an instance in which the manga talks did nothing but benefit the interests of the participants, it seems.
