The royal founder of the Invictus Games is in Toronto today to set the stage for the multi-sport competition.

Prince Harry arrived at a downtown Toronto office building under tight security Friday morning as he begins a series of events in the city the day before the games for wounded soldiers get underway.

The competition, which includes current and veteran members of the forces, runs until Sept. 30 and marks the first time Canada hosts the event.

Harry greeted and posed for photographs with athletes as he awaited the start of a symposium about veterans issues. He will spend more time with athletes training for the Games this afternoon.

On Saturday, Harry will tour Toronto's Centre for Addiction and Mental Health before meeting with Prime Minister Justin Trudeau in the hours before the opening ceremony.

Harry founded the Invictus Games in 2014 as a way to inspire and motivate wounded soldiers on their paths to recovery.

At least 550 competitors from 17 countries are slated to compete in 12 sports, including track and field, swimming and, in a first for the Invictus Games, golf.
