Toronto police say 62-year-old Tung Sheng (David) Wu turned himself in over the weekend.
A B.C. judge ruled earlier this year that he was convinced beyond a reasonable doubt that Wu had ignored a 2003 court order to stop practising dentistry without a license.
Wu, who didn’t turn up in court to respond to the accusation from B.C.'s College of Dental Surgeons, was sentenced to three months in jail.
In May, the college uncovered an illegal dental operation in the Vancouver-area.
It warned hundreds of people to get to get tested for blood-borne illnesses such as hepatitis and HIV.
The college believes Wu performed dental work on more than 450 people.
