Touré, who joined from Barcelona in 2010, will be given an emotional send-off during City’s final home game of the season against Brighton and Hove Albion next Wednesday.
The Ivorian midfielder has made just 16 appearances this season and has not started once in City’s triumphant Premier League campaign.
City have three league fixtures remaining and will be presented with the Premier League trophy after Sunday’s meeting with Huddersfield Town at the Etihad.
While previewing the visit of David Wagner’s relegation-threatened side on Friday, Guardiola revealed that next week’s visit from Brighton will be dedicated to the departing Touré.
“Yes, he will not stay this season,” he said when asked about Toure’s future. “The Brighton game, we will give him what he deserves. All the game will be focused on winning the game and trying to do it for him.
“We have amazing facilities but the club became what they did because of the players like him. Where we are is thanks to what he has done. We cannot forget Roberto and Pellegrini, Yaya was the key player. We are delighted to do this for Yaya.”
