Ivory Coast worldwide Toure, who joined City from Barcelona for a fee of about £24m in 2010, signed a new one-year contract in June 2017.
During his Friday press conference ahead of Sunday's Premier League against Huddersfield, Guardiola confirmed that the Ivory Coast global will be leaving the Etihad Stadium.
His Wembley screamer and stunning solo goal against Aston Villa will forever be etched in the memory of Manchester City fans, who will give him one hell a send off in his last home game against Brighton next Wednesday.
Toure, playing in a midfield two alongside Fernandinho for the duration of the campaign, scored 20 Premier League goals and registered 9 assists for his teammates in 35 outings.
"The Brighton game we will give him what he deserves, one of the most lovely farewells a player can receive".
"We have incredible facilities but the club became what they did because of the players".
He said, "Yaya came here at the start of the journey".
"We can not forget that in the leagues from the period of [former managers] Roberto Mancini and Manuel Pellegrini, Yaya was the key, key, key player".
Meanwhile, Guardiola said he is still in no rush to wrap up his own contract talks. One of the most handsome farewells a player can receive. "But the best way to arrive at the World Cup is to play good in these three games", said the manager of the final Premier League matches. We have time for everything in life.
City will be presented with the Premier League trophy after Sunday's game against Huddersfield after dominating all season.
Guardiola said Belgium global captain Vincent Kompany and England defender John Stones were fit and ready for Sunday's league game against Huddersfield Town after earlier injury problems.
"Yaya is not going to stay next season", Guardiola told reporters ahead of City's home game against Huddersfield Town on Sunday.
