A 58-year-old woman who was scuba diving near the Etobicoke Yacht Club was pulled from the water in Humber Bay with no vital signs Friday afternoon.

Police said the woman was with her husband about 10 metres from the shore near Humber Bay Park.

She was trying to pull scuba equipment out of the water and she fell in.

The woman was still wearing all her gear and her husband had half his gear on, a police source said.

Police said the marine unit responded to a call around 1:30 p.m. and found the woman in the water with her husband and another diver, a Good Samaritan, trying to help her.

The woman was not breathing when she was pulled from the water.

She had been in the water for at least 10 minutes when she was rescued, police said.

The woman was taken to hospital by ambulance with EMS trying to resuscitate her.

A witness who was riding by on his bike said a man who appeared to be the woman's husband was lying on the ground as well, and appeared to be having problems breathing.

Police said the woman's husband is traumatized, but is physically OK.

The woman was taken to St. Joseph's Hospital in serious condition, police said.

Police are speaking to witnesses, including other divers who were in the area, to determine exactly what happened.
