The third annual Ottawa Comiccon begins this afternoon.
This year's convention includes guests like Karl Urban from Star Trek and Giancarlo Esposito from Breaking Bad, along with vendors, panel discussions and workshops.
Pat Mastroianni, who most famously played Joey Jeremiah in Degrassi, is among this year's guests and says they never really thought about how much the program resonated with fans.
"It was only years later where people started to come up to us and say 'Hey, I grew up watching you,' " he said. "We never understood how effective this show was in the lives of just average kids."
He says he loves coming to events like these to catch up with fans.
Comiccon runs through Sunday.
