Canseco studied liberal arts at University of the East. After graduation, he worked for the Philippines Herald and the Associated Press as a journalist, a scriptwriter for the Manila Broadcasting Company, and news director at Eagle Broadcasting. Canseco began devoting himself to writing music when Martial Law broke out in 1972.
He wrote for Sharon Cuneta and Basil Valdez, and his songs were recorded by Regine Velasquez, Zsa Zsa Padilla, Pilita Corrales, Martin Nievera, and Kuh Ledesma. Rey Valera was a lyicist of two of Canseco's songs.
Canseco credited film producer and Vicor Music Corporation owner Vic del Rosario for "my biggest break in the music industry." He became president of the Filipino Society of Composers, Authors and Publishers or FILSCAP in 1973, and was elected as a councilor in the fourth district of Quezon City in 1988.
