Where could a security guard find information regarding legislation of Ontario Private Security?

The correct option is the Private Security and Investigative Services Act. This legislation specifically governs the private security industry in Ontario, outlining the regulations, licensing requirements, and standards of conduct for security personnel. It mandates how security services operate, ensuring that those employed in this field adhere to the legal standards required for safety and professionalism.

The other options, while related to law enforcement and regulatory frameworks, do not specifically pertain to private security. For instance, the Police Services Act mainly deals with the governance of police services and their operations within the province, and the Liquor Licence Act addresses regulations surrounding the sale and consumption of alcohol, which also does not apply directly to the private security sector. While the Private Security Act may seem relevant, it has been superseded by the more comprehensive Private Security and Investigative Services Act, making the latter the most pertinent source of information for security guards regarding their legislative framework in Ontario.
