Toronto Police sources tell 680News that over a dozen uniforms are missing after being sent out to be cleaned over the past few days.
Police fear the uniforms could be used be people to misrepresent themselves as officers.
Toronto police public relations spokesperson Meaghan Gray told 680News she would not comment on the situation but said that security issues are always a concern.
"Certainly during this G20 planning period we've asked for our corporate partners to be particularly aware of any of these situations and to report any cases immediately to us." said Gray.
The thefts come less than two weeks before the G20 summit is to take place at the Metro Convention Centre.
Toronto Police communications officials had no comment.
Betty Skoutakis, the owner of Cadet Drycleaners, told The Toronto Star claims of missing uniforms are false.
“Nothing has been stolen,” she said. “I would know if we’re missing a belt.”
