Service officers continued to patrol the demonstrations. On June 29, a group of gay activists gathered outside a community centre where Toronto Police Service chief Bill Blair was scheduled to speak to demand his resignation for the treatment of women and homophobia within the detention centre. Criticism of policing On December 7, 2010, Andre Marin, Ontario Ombudsman, issued a report called Caught in the Act, an investigation into the legality of the Ontario Public Works Protection Act, and, more specifically Regulation 233/10, in Marin's words, "...known as the secret security regulation, a little known and widely misunderstood legal measure that was supposed to help the police keep the peace, but in my view wound up contributing to massive violations of civil rights."

The regulation was requested by Toronto Police Service chief Bill Blair and debate in the legislature was not required. Orders in Council such as this one are announced in the Ontario Gazette, but the next issue of that publication was to be published after the order expired on June 28, a week after the summit ended. The new law came to light after a York University graduate student, who claimed to have been simply "exploring" the security zone but who did not provide identification when confronted by police, was arrested on June 24 under the regulation. He later vowed to file a lawsuit against the law once the summit ended. The Cabinet later confirmed that the new laws were not "special powers" and that those who were believed to have been arrested
