Prince Harry and girlfriend Meghan Markle joined by her mother at Invictus Games closing ceremony

The royal gave a speech at the closing ceremony in Toronto.

— -- Prince Harry joined his girlfriend Meghan Markle and her mother in a private luxury box at the Invictus Games closing ceremony in Toronto on Saturday night.

"Don’t just move on from these games with happy memories,” he told the crowd. “Instead, make an Invictus goal for yourselves."

Prince Harry encouraged the audience on his closing speech, saying, "Let the examples of service and resilience that you have seen, inspire you to take action to improve something -- big or small - in your life, for your family, or in your community."

Markle's mother, Doria Ragland, a social worker and yoga instructor, flew to the event from Los Angeles to be at her daughter’s side with Prince Harry on his big night. Her attendance is the surest sign yet that an engagement between Markle and Harry may be imminent. Also joining Markle were her close friend, stylist Jessica Mulroney, and Markus Anderson, who attended the opening ceremony with the actress.

On Monday, Markle arrived holding hands with Prince Harry to attend the wheelchair tennis match, as New Zealand faced off against Australia. The couple was seen laughing, smiling and whispering to each other in between chats with children and family members who were also viewing the match.

The Invictus Games, a competition for wounded service members that was founded by Prince Harry in 2014, has been a public coming out of sorts for the royal and his girlfriend of one year. Prince Harry and Markle were introduced by friends in the summer of 2016 in London.

When asked earlier in the day about the future of the Invictus Games, Prince Harry told CTV, "I think I've said many, many times before that Invictus has got a shelf life, because as other people have said, the conveyor belt of wounded coming back from war has ceased to a certain extent -- especially for these 70 nations."

The Invictus Games head to Sydney in October 2018 after being previously played in London, Orlando, and Toronto.

'We have a social responsibility to continue this for as long as it's needed, Prince Harry added. “Which is what I've always said.

'The world needs Invictus, these guys need Invictus, I need Invictus, we all need our fix,” he continued. “We all need to be inspired, we all need to be encouraged and reminded of what duty and service is all about.”
