It is said that a girl was murdered on her birthday many years ago at the Old Finch Road Bridge. It actually common for shady acts of crime and violence to happen near this bridge.
She was tossed into the river below after goodness knows what happened to this poor girl. Her body was never found. The bridge was probably the last thing she saw when she died, so it would make sense she would haunt it.
She may have been walking to a surprise birthday party in her honor and was abducted. She could have been kidnapped for various reasons. We may never know.
If you go to he bridge at night and sing "Happy Birthday", you will hear the girl scream or cry. Many are too afraid to sing and will put the words "Happy Birthday" somewhere on the bridge, with the same results.
