Several incidents occurred during advanced polling on the weekend of November 4–5, 2006, leading to Perruzza and Li Preti accusing one another of dirty campaigning and the breaking of numerous election and criminal laws. Among other claims, each candidate accused staff from the opposing campaign of interfering with elections staff, campaigning illegally at polling locations and intimidating their opponent's voters. No criminal charges were laid by police. However, in a completely unprecedented move, the City of Toronto hired off-duty police officers at a cost of approximately $23,200 to guard all 40 voting locations in the ward on election day to assure that voters would remain safe and free from harassment.
