Local paramedics say that a motorcycle rider lost one leg and may have to have another amputated below the knee after a single-vehicle collision at a racing track near Cayuga, Ontario on Friday night.

It happened at around 9 p.m. at the Toronto Motorsport Park, which is located south of Cayuga, Ont.

Ontario Provincial Police say that the 27-year-old man from Whitby was taken to a Hamilton-area hospital where he remains in stable condition. Haldimand County’s head of emergency services said the victim required an Ornge airlift.

Paramedics originally said the man's remaining leg would have to be amputated, but doctors told the man's family that he would have to have surgery to determine whether the leg could be saved.

The circumstances that led to the crash are not immediately clear.
