Giving testimony means you must take the witness stand and tell the judge or juryCitizens that decide on a person's guilt at trial exactly what you saw or any information you have about the crime. Before you testify, the court clerk will ask if you want to affirm to tell the truth or swear a religious oath on the Bible.
There are four types of evidence – real, demonstrative, documentary and testimonial evidence. This evidence is regulated by the Canada Evidence Act, which was first passed in 1893. This act applies to criminal matters, federal courts and civil matters where the federal government has jurisdiction. Each province and territory also has its own evidence act.
Testimony can be given by an ordinary witnessSomeone who gives evidence in a court proceeding or an expert witnessA person with special knowledge about a crime. An ordinary witness is someone who saw or heard something about the offence. They answer questions about the event in question but do not give their opinion about what occurred.
As the name indicates, an expert witness is a person such as a doctor or forensic accountant with particular expertise about an element of the crime. These witnesses interpret the facts of the case and share their opinion with the court.
The judge typically makes an exclusion order at the beginning of the trial, which means witnesses are not allowed in court during other people’s testimony. Once you have testified, you are permitted to sit in court to hear the rest of the trial unless there is a possibility that you will be recalled to the witness stand at a later time.
Witnesses are not permitted to speak to anyone about their testimony until the trial ends. When you appear in court, you are required to stay until the judge dismisses you. It is not possible to predict how long you will need to be in court. It will depend on what and how much you witnessed and the extent of the questioning by the Crown and the defence.
If you are a witness at an accused person’s trial, the Charter of Rights and Freedoms guarantees you the right not to have your evidence used against you in any proceeding.
