[QUOTE=DocFrankenstein] I've been harassed out of a mall and was supposedly banned from from a public place near a business building. They haven't issued me any papers or called the police - just a verbal statement. [QUOTE]
I spent some of my years between graduating from HS and before going to college (8 yrs) doing private security and investigations. Spent some time doing routine security before moving into investigations and management.
Security companies, rent-a-cops and private corporate security guards (mall) are not recognized as peace officers under Ontario law. While licensing by the province is required for rental security guards, this is to protect the customers.
The mall is private property, and your attendance there is as an invited guest of the stores or businesses in the mall. Same rules apply as to stadiums, sports fields and your neighbour's house. Violate the house rules and you will be invited to leave, and should you make a fuss you will be required to leave and then assisted to leave. Should the assisted part be required, an official officer of the law must be involved and they will make it worth their time, a notice to not return under threat of trespass, or worse, arrest for causing a disturbance.
Please note that a rent-a-cop or mall security do not have any more right to arrest you or detain you than a normal citizen does. the only difference is they have the authority to work on behalf of the mall owner/manager. When an arrest is done, they have the same liability as anyone else. Assault /illegal detention charges against mall/private security should be more common. They have as much authority as you are willing to give them. Unless they are acting to prevent harm to themselves or others, they are out of line.
As to the public place, just how public? Was it a open area in and around the buildings that could be owned by the property management? Such as a square between buildings? If so, this is private property, again.
No notice or writ? This just means the process will begin when the official police are called in. Previous history with the site and these records being provided may cause the officer to take more drastic first steps though. Instead of the notice, an arrest.
Is it a public park owned or overseen by the city, so as to be truly public? Private enterprise has no say. City or controlling civic bylaws have the say.
As an aside, Toronto Transit Authority police are recognized as peace officers under Ontario law and have the full rights of writs, arrest and confinement as police officers. Don't mess with them.
I'm not a lawyer, just some of the experience and training I've been through. Like any other comments, these are just my view as my experience has taught me. Use at your own risk. Nor do I advise agarivating these annoying people as it is a waste of time explaining yourself to the local constabulary.
