Prince Edward spent Sunday doing his part for charity, by participating in Ontario's Walk Now for Autism event.

The Earl of Wessex, Queen Elizabeth's youngest son, joined more than 5,000 people for the fourth-annual event at Nathan Phillip's Square Sunday morning.

Some who had the chance to meet him said he was surely Prince Charming.

"It was nice to meet him," said Lindsay Fenn.

After the walk, Prince Edward met with Ontario's Lieutenant Governor David Onley and Toronto Mayor David Miller to launch a new playground.

He helped unveil a plaque at Neshama Playground, a universally accessible playground in Oriole Park, near Yonge Street and Davisville Avenue. Prince Edward also helped plant a maple tree in the park to help symbolize growth.

Yesterday, the Queen's son was in Kingston where he was welcomed at Fort Henry by a Cannon salute. The prince thanked Canada for contributing to the mission in Afghanistan.

Prince Edward is seventh in line to the throne.
