The England international striker was a target for West Ham, QPR and Leicester City on deadline day but the Major League Soccer side have no intention of letting him go
Goal understands that QPR and West Ham were both interested in signing the England international on Monday, with Leicester City also joining the race.
But Rs chairman Tony Fernandes said of any possible deal that “it’s whether the Canadians are willing to release him now” and the Major League Soccer club are determined to keep hold of their prized asset.
"Obviously the bids that were most intense were for Jermain Defoe," Leiweke told the Toronto Sun. "We're not interested in him going anywhere.
"There were three different clubs that approached us."
Defoe joined the MLS side from Tottenham in January, briefly being loaned back to White Hart Lane before the start of the American season.
