Canadian Criminal Law/Identity
Identity of the accused person is always a required element to be proven for a given offence. As with all essential elements, it must be proven beyond a reasonable doubt.
It can be proven by way of the following methods, none of which are necessarily determinative:
- an eye-witness who IDs the accused as person seen committing the offence
- exclusive opportunity
- security system photographs/video
- voice identification
- finger prints
- foot prints
Courts are very cautious of eyewitness evidence as it is considered “inherently unreliable” as there are “dangers inherent in eyewitness testimony”. It is “well-established” that the "frailties" of eyewitness identification "can lead to wrongful convictions, even in cases where multiple witnesses have identified the same accused”. Even honest witnesses may misidentify individuals. Consequently, identification evidence is treated differently than other evidence and special care and caution should be taken. Judges are required to give special cautions when considering identification evidence. This includes instructing himself and bearing in mind the guidelines when considering evidence of identification.
A court of appeal "will be subject findings [on identity] to closer scrutiny than is generally the case with findings of fact”.

Weighing identity evidenceEdit
Bald assertions of identity by witnesses should be given little weight. The court should consider the foundation of the statement including the opportunity and ability to observe. 
It has been recommended that cases resting entirely on eyewitness testimony should require the judge to do the following: 
- recognize the danger of convicting based on eyewitness identification only;
- note the significant factors which may have affected the identification; and
- address those factors.
It is "incumbent upon Crown counsel to ensure that all relevant circumstances surrounding pretrial eyewitness identification procedures be fully disclosed to the defence and be made available for scrutiny by the trier of fact."
The fundamental factors affecting the weight of eyewitness evidence are: 
- opportunity to observe
- light conditions
- the distance from the witness to the suspect
- the eyesight of the witness
- colour perception
- previous acquaintance with the accused
- focus of attention or distraction
- presence or absence of distinctive features or appearance of the suspect/accused
Extra caution should be taken where the witnesses had a limited opportunity to observe and the confirmative opportunity occurred while the accused was under arrest.
Absent supporting evidence, a judge cannot say that stress upon the witness is a neutral factor in accuracy of observations.

The key rule in giving a photo line-up is that the procedure is fair.
It was recommended in the Sophonow Inquiry that in order to avoid false identification through line-ups the procedure should include the following:
- The photo pack should contain at least 10 subjects.
- The photos should resemble as closely as possible the eyewitnesses' description. If that is not possible, the photos should be as close as possible to the suspect.
- Everything should be recorded on videotape, or failing that, audiotape. In addition, or as a minimum alternative, all comments of the witness should be recorded verbatim on the form accompanying the line-up and signed by both the officer and the witness.
- The line-up should be presented by an officer who is not involved in the investigation and does not know who the suspect is.
- The officer showing the line-up should advise the witness that he does not know who the suspect is or whether there is a suspect in the line-up. The officer should also tell the witness that it is just as important to clear the innocent as it is to identify the subject.
- The photopack should be presented sequentially, not all together.
- Police officers should not speak to the witness after the line-up regarding his ability or inability to identify anyone.
Several cases have adopted these requirements or something similar.
Other factors considered include:
- evidence of distinguishing features linking the accused and the perpetrator identified by the line-up photograph.
- opportunity for the witnesses to see the perpetrator;
- familiarity with the accused prior to court;
The Sophonow guidelines for line-ups are not legally binding and so failure to follow them will not necessarily be fatal to the identification evidence.
The prior familiarity of the witness to the accused is a factor that goes to weight.

A witness can testify to the contents of a video establishing identity of the accused without showing the video. It is generally considered akin to actual observations.
A witness who is familiar with the appearance and idiosyncrasies of the accused that is not apparent to the trier of fact, may testify to identity where the witness can 1) state the particularities of the idiosyncrasies; and 2) can show where the idiosyncrasies are revealed on the video. A voir dire must be held to determine whether the person, such as a police officer, can testify to the likeness of the video image to the suspect.
A person who is not familiar with the appearance of the accused cannot testify on identification of the accused in a video.
Identification of an accused in the dock is generally undesirable and unsatisfactory, and so adds very little weight to the proof of identity.

Courts have generally made a distinction between identity evidence and recognition evidence. The difference being that identity involves a witness matching a previously observed stranger with that of the accused. Recognition is where the observer knew the person being observed and the issue is not simply identifying a person by description, but rather recognizing the person through their acquaintanceship.
In admitting recognition evidence, there must be sufficient indicia for a threshold degree of familiarity which depends on
- the length of the prior relationship between the witness and the accused;
- the circumstances of the prior relationship between the witness and the accused; and,
- the recency of the contact between the witness and the accused prior to the event where the witness recognized the accused.
These indicia go to the weight of the evidence along with "the cumulative effect of recognition evidence provided by more than one witness and the circumstances under which the witness recognized the accused."
Before a person can claim to recognize a person they must establish that they had a prior opportunity to personally observe the accused and become acquaintanced with him.
Recognition simply means that "the witness's evidence is based in part on his or her dealings with the accused before the crimes were committed"
Recognition evidence is considered more reliable and has more weight than identification evidence.
Resemblance without anything more is not sufficient to establish identification. Other inculpatory evidence is needed.
