The Trespass to Property Act is a statute enacted by the Legislative Assembly of Ontario, Canada.
There are many methods of notifying unwanted individuals that they have been banned (for future access), but the most common is a personal notice to the offender.
[2] In general under the Act, owners must give notice either orally or in writing except where fencing is applied around gardens or areas under cultivation, or the keeping of animals.
Access to the door of a building on premises for lawful purposes is protected except where specifically prohibited.
[1] A sign showing a graphic representation or wording of prohibited access is sufficient.
