"This is not a stunt," he says on his website. "This is me performing an art I’ve devoted my life to."

The 33-year-old man plans to walk about 1, 804 feet across the falls at 197 feet above the gorge bottom.

He plans to string his cable closer to the cataract from the Goat Island lookout on the U.S. side, across the Horseshoe Falls, to a paved terrace below the visitor's centre on the Canadian side, according to his website.

The walk reportedly cost about $1.2 to $1.3 million, according to the Toronto Star. If he succeeds he will be the first to cross over the brink in more than 100 years.
