Fraud cost the city a half-million dollars in 2012.

That according to Toronto Auditor General Jeff Griffiths who issued his report on fraud Wednesday

Several employees were fired for a number of incidents of fraud last year. Some of the incidents included false benefit claims and abusing sick leave.

In one case a worker was caught looking at porn on a city owned computer. He has been fired.

Another employee defrauded a city-sponsored charitable organization and other groups of almost $50-thousand over six years. That is under investigation by police and the employee was fired.

In another case, an employee collected about $1,300 in overtime pay without getting approval or having the documentation. That person is no longer employed by the city and the money has been recovered.

The city says they've recovered over half of the money they say is owed.
