Richmond Hill resident Joe Lennane, 52, died Tuesday.
Lennane was a concert tour manager and had just finished up the last tour date for the band Maroon 5 in Switzerland when he collapsed.
His business partner, John Dubuque, said Lennane was about to fly home to Richmond Hill to be with his family for the holidays.
Lennane has reportedly managed tours for numerous music acts through the years including Joan Jett, Luther Vandross and Meatloaf. A local funeral is expected to take place this week.
