Looking dapper in a blue suit and tie, he hopped on the phones and joined brokers on the trading floor at ICAP Charity Day in support of Sentebale, a charity he founded with Prince Seeiso that provides psychological support for children living with HIV/AIDS in Southern Africa. He sealed a few deals during the event, including one worth $635 million.

"Prince Harry closes a deal at #ICAPCharityDay to raise vital funds for charities like @Sentebale," a tweet from Kensington Palace read.

Another tweet was accompanied by a video of Prince Harry hilariously letting out his best "pirate's noise."

ET confirmed that Prince Harry flew to Toronto after wrapping up his Caribbean Royal Tour on Sunday. Royal expert Kate Nicholl told ET at the time that the two wanting to spend time together was understandable, as Meghan won't be joining her beau for the holidays.

"[Harry] knows the rules of the royal family and he knows that until they get engaged, Meghan will not have a place around that Christmas dinner table," she explained. "If you think about all those years that Prince William was courting Kate Middleton, she had to wait 10 years until she was invited to Sandringham."

Fans were quick to notice the Maya Brenner Asymmetrical Letter necklace, with many believing the letters represented H for Harry and M for Meghan.
