Use of force theory
- Guards must understand use of force theory, the use of force model and keeping composure under stress.
- Criminal Code s. 25: when required or authorized by law to do something in administering or enforcing the law, a person (like any member of the public) acting on reasonable grounds may use as much force as is necessary.
- s. 26: anyone authorized to use force is criminally responsible for any excess.
- Excited delirium: signs of severe mental disturbance; may be violent and aggressive; avoid agitating or exciting them. Causes include drug use, mental illness, brain injuries or tumours, heart disease, high blood pressure, high or low blood sugar, respiratory problems, fever.
- Positional asphyxia: can happen to anyone restrained; much higher risk with excited delirium. Do not hold face down; no pressure on the chest.
- National Use of Force Model: situational model; assess the subject's behaviour (inner circles) and choose an appropriate response (outer coloured circles); e.g. no hard physical force on a cooperative subject.
- Syllabus: specialized training is needed to use defensive equipment; 2 hours in class.
Protection of persons acting under authority
- (1) Justified, if acting on reasonable grounds, in using as much force as is necessary — applies to private persons too.
- (3) Not justified in using force intended or likely to cause death or grievous bodily harm unless believing on reasonable grounds it is necessary to preserve self or someone under their protection from death or grievous bodily harm.
Prevention of offence
- Anyone may use as much force as is reasonably necessary to prevent an offence for which the offender could be arrested without warrant and that would likely cause immediate and serious injury to a person or property.

- Factors include: nature of the force or threat; how imminent and whether other means were available; the person's role; weapons; size, age, gender and physical capabilities; relationship/history; proportionality of the response.
Defence of property
