The 21-year-old singer, who appeared at the hearing via video link from Los Angeles, received an absolute discharge on the assault charge and a C$750 ($600.00) fine for the careless driving charge. He was also required to pay a C$100 victim surcharge.
The pop star had originally been charged with dangerous driving following the August incident, but that charge was dropped.
The incident happened during a visit to the Stratford, Ontario, area with pop star Selena Gomez. The two were “disrupted by the unwelcome presence of paparazzi,” his lawyer said at the time.
Bieber’s lawyer, Brian Greenspan, said the absolute discharge for the assault “recognised the fact that it was an incident that was somewhat provoked and that it lasted less than a minute.”
“The assault was described even by the photographer as a couple of slaps, certainly three at the most, that he deflected with his shoulder,” Greenspan said, adding that Bieber acknowledged his responsibility to the judge.
Bieber, whose songs include the hits “Boyfriend” and “Beauty and a Beat,” has been a favourite paparazzi target and has had several run-ins with the law.
In August, he pleaded guilty to careless driving and resisting an officer without violence in Florida, part of a deal to resolve allegations that he had been drag racing in a Lamborghini under the influence of drugs and alcohol.
In July, Bieber pleaded no contest to misdemeanour vandalism for pelting a neighbour’s California home with eggs. He was sentenced to two years probation.
