The former chairman of the TTC is being asked to pay about $3,500 after he overspent his $125,000 office budget in 2010, the Toronto Star reports.

Karen Stintz, the new TTC chair, says Giambrone's overspending was outlined in a memo sent by TTC general manager Gary Webster to the current slate of commissioners.

Stintz, also a the city councillor for Ward 16, says the details of her predecessor's overspending will be discussed at a TTC meeting on March 1.

Previous reports from the Star revealed Giambrone took French lessons on the taxpayer's tab after he said he was quitting municipal politics.
