Our summary of what the official handbook says on this topic, in our own words. Read it before or after the practice questions above, then check the original chapter. Read the official chapter ↗
No special powers
- A licensed PI is not a peace officer and has only a private citizen's powers; misrepresenting legal authority breaches the code of conduct.
Arrest without warrant
- Anyone may arrest a person found committing an indictable offence, or a person believed on reasonable grounds to have committed a criminal offence and escaping while freshly pursued by people with authority to arrest.
- The owner, a person in lawful possession, or someone they authorize may arrest a person found committing a criminal offence on or in relation to the property, at the time or within a reasonable time if a peace officer cannot feasibly make the arrest.
- A private arrester must deliver the person to a peace officer forthwith.
Force
- A person authorized by law may use as much force as necessary on reasonable grounds; deadly force only to prevent death or grievous bodily harm; liability for any excess.
- Self-defence: reasonable belief in force or threat, purpose of defending, act reasonable in the circumstances; defence of property for a person in peaceable possession, if reasonable.
Charter ss. 8–10, 32
- Rights against unreasonable search or seizure and arbitrary detention; on arrest, the right to be told the reasons promptly and to retain counsel without delay; the Charter applies to government action.
Criminal harassment
- Offence to repeatedly follow, monitor the location or movements of, repeatedly communicate with, beset or watch the home or workplace of, or threaten a person, knowing or reckless that they are harassed, if they reasonably fear for their safety (including psychological safety); maximum 10 years on indictment.
