A brahmin of Takkasilá, who killed King Dhanananda and placed Candagutta on the throne (Mhv.v.16f.; Mbv.98). In his youth Cánakka looked after his mother, and finding that she was worrying lest he, who was destined for kingly power, should leave her, he broke his tooth, having been told that there his luck resided. One day, on going for alms to Dhanananda's palace, he was insulted, and in order to avenge the insult he kidnapped the king's son, Pabbatakumára. He then adopted Candagutta and, finding him better fitted for kingship than Pabbata, he contrived that the latter should be killed. When preparations had been made, he induced Candagutta to rise in revolt against Dhanananda, and, finally, to kill him and ascend the throne. (See MT.181ff for details, also Candagutta).
The Theragáthá Commentary (i.440) states that Tekiccháni's father, Subandhu, roused the jealousy of Cánakka, who had him put in prison.
