A brave parachutist has been jumping off the CN Tower this week as part of a promotional video shoot for the Pan Am Games.

The person jumped off the restaurant level of the tower on Tuesday morning and twice on Wednesday morning, first at 7 a.m. and again at 8 a.m.

Passing commuters were startled by the jump, taking to social media to question what they saw.

"Did anyone… just see the dude in the parachute near the CN Tower?? What the what?!" one person wrote on Twitter.

"Actually just watched someone parachute off the CN tower. Actually happened," another wrote.

"Well, that was crazy," a third posted.

The jumps were part of a promotional video for the 2015 Toronto Pan Am and Parapan Am Games, though organizers did not provide many details.

The parachutist jumped from the deck where the EdgeWalk takes place, at a height of 342 metres.

The Pan Am jumper is only the third known to have parachuted from the tower.

Stuntman Dar Robinson jumped off the edge for a movie shoot in 1979, serving as Christopher Plummer's stunt double in "Highpoint."

Four years before the movie shoot, steelworker William Eustace leapt off the tower, which was still under construction, in 1974.

According to media reports at the time, Eustace was charged under the federal Aeronautics Act, and was ordered to pay a fine of $50.
