OTTAWA - Officials representing Toronto restaurant owners say they are unaware of any who have been compensated for loss of business during the G20 summit.

The Canadian Restaurant and Foodservices Association is telling a Commons committee its Toronto members suffered significant losses during the summit.

A survey of members found that 93 per cent in the downtown area and 54 per cent outside the core reported a significant drop in activity during and in the days leading up to the three-day summit.

But they complain the system set up by Ottawa to reimburse operators for loss of business is so complex and costly that most have not even applied for compensation.

As well, they say the system unfairly excludes owners who decided to shut down during the late June summit, or were not in the immediate area, or suffered property damage.

Earlier, Toronto police chief William Blair told the committee he estimates damages from violence and vandalism during the summit at about $2 million.

Blair said many of those responsible have been identified and will be prosecuted.

On Wednesday, the police chief said about 90 police officers who removed identifying name badges from their uniforms will face disciplinary action if they purposely did so to avoid scrutiny.
