The second of three people killed Saturday when the Ferrari they were riding in crashed in Dubai has been identified by his family as 27-year-old James Portuondo of Toronto.

Portuondo, along with boxer Cody Nixon, died when the Ferrari slammed into a lamppost at about midnight local time. A third person, who has not been identified, also died in the crash, which split the Ferrari in half.

Crystal Lopresti, Portuondo's sister, said Portuondo and Nixon are cousins. In an email to CBC News Monday, she described Portuondo as a "beloved son, grandson, brother, brother-in-law, and uncle."

Lopresti said her brother and Nixon were on holiday.

She said the car rental company called the family with the news of the accident.

"Saturday night, the car rental company called and said 'Your son died, come get his passport.'"

Portuondo was the youngest of three and worked at the family's auto body shop in Mississauga, Lopresti said.

"He would give you anything, and he would do anything for me. He didn't care what people thought. He was a crazy, silly goof."

Nixon chronicled his globe-trotting adventures on his Instagram account, TravelWithCody, where pictures show him jumping out of planes, scuba-diving and lounging on beaches in exotic locations. 

His final post shows him posing with a newly rented Ferrari in Dubai. 

Nixon was a former member of Motor City Boxing in Oshawa, Ont., and represented Ontario at the Canadian Boxing Championships in 2012, boxing coach Don Nelson told CBC News. 

The federal government said it is working with Canadian consular officials in the United Arab Emirates to provide assistance to the families.
