More than 300 people are at the annual Stair Climb for Cancer underway in Niagara Falls this morning.
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.
Organizers hope to raise $40,000 at the event.
Tory Alston of Jacksonville, Florida beat his own stair climb record today.
Last year he set a record time of 3 minutes 21 seconds, today he climbed the stairs in 3 minutes 2 seconds.
