Dominic Shaw rappels down Calgary building in a wheelchair

On Thursday afternoon, a Calgary man repelled 30 stories down the city's Sunlife Plaza for charity.

Doing so made Dominic Shaw, an accomplished wheelchair athlete, the first wheelchair-bound person to ever rappel in Calgary's annual Easter Seals Drop Zone.

"I live in a building with 17 floors, so I think every day of the last month I've looked out and go, 'OK, it's double this height,'" he told CBC News.

For more than 85 years, registered-charity Easter Seals has been serving Canadians with disabilities. Every summer, more than 6,000 children attend Easter Seals' 15 fully accessible camps where "they are asked to get out of their comfort zones to overcome fears and try new things."

Shaw told CBC News that he went to those camps as a kid.

"Easter Seals is doing a job that not many organizations really understand how to do. They don't just throw money at a problem, they provide real solutions for people," he said.
