At the time of arrest, an officer must typically inform the accused of the following and confirm that they understand:
- inform of reason for arrest
- Charter of Rights caution / Right to Silence
- right to speak to a lawyer
- access to legal aid

Validity of Arrest
An arrest consists of two elements:
- the actual seizure or touching of a person's body with a view towards his detention or
- the pronouncing of "words of arrest" to a person who submits to the arresting officer.
An arrest will only be lawful if:
- police have a subjective belief that there are reasonable and probable grounds to arrest the accused.
- the grounds must be objectively justifiable
