Woodstock police closed a stretch of Vansittart Avenue early Tuesday morning while investigating a collision near Ridgewood Drive.
Officers responded just before 8 am to reports of a crash between an SUV and a motorcycle.
One person was taken to hospital with serious – but not life threatening – injuries, police said.
No charges have been laid yet, but the investigation is continuing, police said.
Vansittart Avenue, a busy Woodstock road, was temporarily closed from Lakeview to Oxford Road 17 but was reopened in the mid-afternoon.
