Police officers in Canada do not have an unlimited power to inflict harm on a person in the course of their duties. While, at times, the police may have to resort to force in order to complete an arrest or prevent an offender from escaping police custody, the allowable degree of forced to be used remains constrained by the principles of proportionality, necessity, and reasonableness.
Police actions should not be judged against a standard of perfection. It must be remembered that the police engage in dangerous and demanding work and often have to react quickly to emergencies. Their actions should be judged in light of these exigent circumstances.
