Daniel Boria, 26, told police he was planning on parachuting into the Calgary Stampede, a rodeo event, to promote his cleaning-products company.
“I was sitting in a lawn chair looking down through the clouds at 747 airplanes and looking up to a cluster of helium balloons,”
Mr Boria said he “somersaulted out the chair” and parachuted down to safety after the balloons took him too high.
Mr Boria has been charged with mischief causing danger to life and could face further charges. The stunt reportedly used 120 over-sized party balloons and $9,500 (£6,000) worth of helium.The whereabouts of the chair are unknown, Inspector Kyle Grant said.
