The actor, who plays Sean Tully's boyfriend Marcus Dent, made his Weatherfield comeback earlier this year after previously departing the cobbles in 2008.
Marcus's storyline has seen him help Sean to raise his son Dylan, who is staying with the couple while mum Violet recovers from an accident.
Although Dylan is expected to return home to Violet later this year, it has now emerged that Marcus will be staying put on the street.
Condou told So So Gay of his Coronation Street return: "The producers had been looking to bring me back for a while, as far as I know. I'd had a few conversations with them, and they kept saying they'd love to bring me back if I was interested. I'd always say yes, but only if the storyline was right. This storyline came about, and it just made a lot of sense to me - obviously, it's something very close to my heart.
"Originally I said I'd just come back for the parenting story, because the child playing Dylan could only be with us for a finite period. But I enjoyed it so much that at the end of my contract, when I was asked if I'd stay on, I said, 'yep'. So I'm staying!"
Antony Cotton, who plays the role of Sean, also recently signed a new contract with the Weatherfield soap. Additionally, Samia Smith has confirmed that she is staying on as Maria Connor for at least another year.
In real life, Condou is expecting his second child with best friend Catherine. They already have a 2-year-old daughter named Georgia, who splits her time between living with Catherine and living with Condou and his partner Cameron.
