Prince Harry is in Toronto to promote the Invictus Games, which he established in 2014. It is the only international adaptive sporting event for wounded, ill and injured active duty and veteran service members, inspired by the US-based Warrior Games. NATO has provided support to the Ukrainian and Afghan teams.
