A Canadian bride-to-be posing for photos in her wedding dress died today after she slipped and plunged over a waterfall north of Montreal, police say.

The unidentified woman slipped on a rock about 2 p.m. ET, tumbled over a cliff and into the raging waters of Dorwin Falls, in Rawdon, Quebec, provincial police told the Canadian Press. Her body was recovered about four hours later.

Two witnesses suffered "extreme shock" and were taken to a hospital.

The woman was to be married "within days," said police spokesman Sgt. Ronald McInnis. He would not confirm whether the wedding was scheduled for Saturday.

He said that the forested waterfalls are about 60 feet tall at their highest point and that the current "is very violent, it's very rocky."

"The people who fall at that spot usually perish. It doesn't give you a chance," McInnis said.
