The lawyer for a 22-year-old Ancaster man accused in a massive hack of Yahoo emails said they will go ahead with an extradition hearing unless an agreement is reached with the U.S. before then.

Karim Baratov was arrested on March 14 under the Extradition Act after U.S. authorities indicted him and three others for computer hacking, economic espionage and other crimes.

Baratov is facing charges for his role in the hack of more than 500 million Yahoo accounts in an elaborate cyber attack that also involved two alleged Russian intelligence officers and a Russian hacker.

Baratov’s lawyer, Amedeo DiCarlo, said that if an agreement with the U.S isn’t reached by the September 8 hearing date, he plans to fight to keep his client in Canada.

DiCarlo said earlier this month his client may not fight his extradition to the U.S. He said he thought the quickest way to get him out of jail is to deal directly with the U.S. authorities. An extradition hearing is currently scheduled for September 8.

Baratov is accused of hacking 80 Yahoo accounts and faces 20 years in prison in the U.S. if convicted.
