Question: An individual is trespassing on private property, refusing to leave despite repeated requests from a security guard. Which of the following best describes the security guard's power to arrest this individual in Alberta?

Answer options:

• A security guard has no power to arrest for trespassing; it's a civil matter.
• A security guard can arrest if the property owner specifically authorizes it in writing beforehand. ✅ A security guard can arrest if they find the person committing a criminal offence, such as wilful damage related to the trespass.
• A security guard can only detain the person until police arrive, but not formally arrest them.

Correct answer: A security guard can arrest if they find the person committing a criminal offence, such as wilful damage related to the trespass.

Explanation: A security guard, as a private citizen, can only make an arrest under the powers granted by Section 494 of the Criminal Code. While trespassing is often a provincial or civil matter, an arrest is permissible if the trespass constitutes a Criminal Code offence, such as breaking and entering or mischief (wilful damage).
