Manitoba's fire commissioner has been fired after financial irregularities were found during a routine audit.

Chris Jones, who's held the job since 2009, was let go this week.

Two other employees have also been fired in the shakeup and a fourth is under investigation, said Rick Stevenson, assistant deputy minister of labour relations with the provincial Treasury Board secretariat.

The audit revealed questionable expense claims for travel and accomodation dating back a few years, Stevenson said, noting the irregularities involve employees in Winnipeg and Brandon.

An internal memo was sent out on Tuesday by Jeff Parr, deputy minister in the department of labour and immigration, stating that Jones "is no longer with the Office of the Fire Commissioner" and that David Schafer will take on the role of acting fire commissioner.

Stevenson won't identify the other employees who have been fired.

A forensic audit has now been ordered and will be conducted by Manitoba's Auditor General Carol Bellringer.

She has no time frame yet on how long that will take.

The audit will provide a better understanding of how much money is involved, said Stevenson. It could also result in charges being recommended.
