Csányi did not participate in the Battle of Mohács, where his relatives, Ambrus Sárkány and Zsigmond Pogány were killed. He held the office of vice-"ispán" of Zala County until 1527. In that year, he represented his county alongside István Gyulafi and Dénes Háshágyi at the Diet of Buda which was convened by John Zápolya. Following that Csányi gradually retired from public life. On 1 January 1529, he bought lands in Alsókustán from local noble László Hollósi. A county "dicalis" of 1531 listed Csányi's property: 12 "porta"s in Csány and 16 "porta"s in Vindornyaszőlős. In his last years, he was "familiar" to the powerful Nádasdy family alongside his brother and sons. According to an undated letter of his son Ákos to his lord Tamás Nádasdy, his father Balázs Csányi and two of his brothers, István and Gergely died of a plague which had broken out following the Ottoman campaign and the Siege of Kőszeg in the summer of 1532.
