The annual Stair Climb for Cancer at the Skylon Tower in Niagara Falls takes place tomorrow.
All proceeds from the event, that sees participants mount the 660 steps to the top of the observation deck, are split between the Canadian Cancer Society's Wheels of Hope program and funding research into childhood cancer.
Registration starts at 8:30am with the first climb starting at 9am.
For the first time, people can sign up to do a "virtual climb" and participate without even being there.
