It was my great pleasure to formally deliver to Jack Robinson, COO of the the CN Tower, a certificate acknowledging the EdgeWalk as the World's highest external walk on a building.  The EdgeWalk measures 1,167.97 feet, or 356 metres high, and participants experience a walk on a 5 foot wide platform around the entire building.  It is another amazing example of the CN Tower pushing the envelope of what is possible and into the realm of Guinness World Record territory.  And for me, what a thrill to be able to present the certificate, (which was securely harnassed to my jumpsuit), to Jack Robinson on the actual platform itself!!
