<P> A metal staircase reaches the main deck level after 1,776 steps , and the SkyPod 100 m ( 328 ft ) above after 2,579 steps ; it is the tallest metal staircase on Earth . These stairs are intended for emergency use only and are not open to the public , except for two times per year for charity stair - climb events . The average climber takes approximately 30 minutes to climb to the base of the radome , but the fastest climb on record is 7 minutes and 52 seconds in 1989 by Brendan Keenoy , an Ontario Provincial Police officer . In 2002 , Canadian Olympian and Paralympic champion Jeff Adams climbed the stairs of the tower in a specially designed wheelchair . The stairs were originally on one of the three sides of the tower ( facing north ) , with a glass view , but these were later replaced with the third elevator pair and the stairs were moved to the inside of the core . Top climbs on the new , windowless stairwell used since around 2003 have generally been over ten minutes . </P>
