In Mig'maq, in the context of an applicative suffix on the verb, but not otherwise, the possessor of the direct object can control object agreement on the verb, rather than the direct object itself. Agreement features are person and number. Possessors of subjects or other objects cannot control agreement on the verb, including derived subjects in passives. Possessors that control agreement are arguably topical.
