Wanda Liczyk, the former city treasurer at the centre of a multi-million dollar computer-leasing scandal at Toronto city hall, isn't off the hook yet.

Earlier this year, the Institute of Chartered Accountants of Ontario decided not to charge Liczyk with professional misconduct even though a judicial inquiry found she had been in a conflict of interest.

The institute said Liczyk was unlikely to commit similar acts in the future, but an independent reviewer has now recommended the institute reconsider, arguing that charges serve as a deterrent and help maintain public confidence in the institute's regulatory process.

That means Liczyk's actions will be reviewed again by a professional conduct committee, which could lead to a public disciplinary hearing before the institute.

A 2005 judicial inquiry into how the city awards contracts found that Licyzk actively participated in directing business to a former lover and to a close friend.

It also found she buried the purchase overrun in reports to council.

Justice Denise Bellamy investigated how a $40-million computer contract between the City of Toronto and MFP Financial Services ballooned to more than $100 million.

Liczyk left city hall in 2001 for a job as senior vice-president and chief financial officer at Toronto Hydro.

She quit that $320,000-a-year job in 2004 shortly after testifying at the judicial inquiry and questions were raised about her conduct as a city employee.
