Robert Lafreniere, head of Quebec's Permanent Anti-Corruption Unit, UPAC, has tendered his resignation.

The announcement coincides with election day in Quebec. 

Lafreniere will reportedly leave his post on November 2nd. 

No further details were released. However, Lafreniere's tenure with the UPAC has been openly criticised by detractors. 

Lafreniere was appointed to the position in 2011, when the UPAC was introduced as the first anti-corruption squad of its kind in Canada. 

It was inaugurated by then-Minister of Public Security, Robert Dutil.
