RCMP say the 17-year-old girl got out of her vehicle at about 1:30 a.m. on Wednesday and noticed a vehicle pull up behind her.
She briefly spoke with the driver but as she walked back to her car police say the man attacked her and that at one point she lost consciousness.
Mounties are calling the incident an attempted abduction and say the girl suffered cuts to her hands and knees but did not require treatment in hospital.
Const. Gary O'Brien says the teen drove home and called 911.
The alleged attacker has been described as someone in his early to mid-20s.
