The 18-year-old 'Baby' hitmaker earned a diploma at St Michael Catholic Secondary School in his native Ontario, but he did not turn up in person for the commencement ceremony on June 28, reported Contactmusic.
"We are very proud of Justin and all of the other 192 graduates of St Michael School, however, we're not at liberty to discuss any personal plans or information about Justin or any other graduate," said Tim Doherty, school's principal.
The singer, who is also busy promoting his new fragrance, took courses through e-learning.
