The 20-year-old pop star was not in court Monday when the trial date was set.
He was arrested and charged with dangerous driving and assault last Aug. 29 after a collision between a minivan and an ATV in a rural area northeast of Stratford.
A lawyer for the singer said Bieber was on a "peaceful retreat" with Selena Gomez — his on-again, off-again girlfriend — that was disrupted by paparazzi.
Ontario Provincial Police said the driver of the ATV and an occupant of the minivan "engaged in a physical altercation."
Const. Kees Wijnands said there were no injuries as a result of the collision, but wouldn't say whether there were any injuries from the altercation.
A court spokeswoman said the case would next be before the court on May 25, when a hearing would be held to confirm the July 14 trial date and determine whether the July 15 date would be required.
Just a few days before the incident, Bieber's car was hit from behind by a vehicle driven by a photographer in Hollywood.
