The Prince met the teams from around the world training to compete in swimming, volleyball and wheelchair basketball at the Pan Am Sports Centre in Toronto.
The Aussie team gave the Prince two boxing kangaroo toys for Prince George and Princess Charlotte, which Prince Harry joked he would throw in the water.
“I thought he was going to punt it into the pool for a second,” said Australian Athlete, Chris Clark Clark. “He has a good sense of humour…he’s a very approachable young man.”
Harry founded the Games in 2014 as a way to inspire and motivate wounded soldiers on their paths to recovery.
“We’re using the Games to get out of dark holes and back into life — and without Harry, we wouldn’t be here having fun and enjoying the camaraderie, which is what you miss from the army days,” said Charlie Walker, a coach of the United Kingdom’s sitting volleyball team.
This weekend, the Prince will visit Toronto’s Centre for Addiction and Mental Health before meeting with Prime Minister Justin Trudeau. Later in the evening he will attend the Games’ opening ceremony at the Air Canada Centre, which will feature performances by Sarah McLachlan, Alessia Cara and the Tenors.
