Well, technically, being filler doesn't mean that it's not canon, but it's mostly the case. In the case of the Boruto anime however, the manga author has explicitely connected the anime to the manga, back during the Kiri-arc. So whatever you want to define as canon, the manga and anime are on the exact same level.
