The doctrine of "present memory revived" is the manner in which a witness may refresh their memory.
A witness can use any document to refresh their memory.
The key elements to the use of the doctrine of present memory revived is:
- an independent memory of events;
- the inability to recall the memory; and
- the "thing" is capable of "sparking" or "jogging" the independent memory
In order to prevent the witness from exploiting this rule to "simply regurgitate" their evidence rather than actually refresh their memory, opposing counsel must have access to the item used to refresh memory.
It will not be applicable where the witness simply states something that contradicts something that was made in a prior statement.
Refreshing memory is permitted by the doctrine of "present memory revived" which permits a testifying witness to jog their memory. It is not the aid that becomes the evidence but rather it is only a mechanism to evoke the memory of the witness which produces the evidence.
Traditional doctrine of refreshing memory permits a person to use anything in writing "made or verified by himself concerning and contemporaneously with the facts to which he testifies". Where it was not written by him he reviewed the statement when the facts were fresh in his mind and "he knew the statement to be correct."
More recent views have suggested that a witness "may consult with any document while testifying. As long as the document sparks an actual recollection of the event recorded".Given that the document used to refresh is not evidence and the ability for counsel to cross-examine the witness on their memory, "there is no reason why the document that is used as the memory trigger should have to meet the strict requirements of time, verification and accuracy. In other words, subject to an exclusionary discretion where the document may be inappropriately suggestive, a witness should be entitled to inspect any document in court to see if it triggers an independent recall".

Distinction with Past Recollection Recorded
Present memory revived is the method of "jogging" a memory and bring it back into the witnesses mind. The witness may examine a thing, such as a note, which has the effect of putting a memory into mind. By contrast Past Recollection Recorded permits the admission of a record that is a past memory reduced to record, regardless of the witnesses ability to bring the memory back into mind. 
Present memory revived is separate and distinct from Past Recollection Recorded which is a form of hearsay. In the later case, the document is evidence that the judge may rely upon.

Timing of Refresh
There's no need for the documents be contemporaneous with the events it documents.
It does not make a difference how long before trial the refreshing occurs.
Opposing View on Memory Refresh
Certain courts have interpreted the requirements of memory refresh as including the additional requirements that:
- the record be made contemporaneous to the events that it records
- it was written in the hand of the person who is testifying, unless it was read by the witness when the memory was fresh in their mind;
- the record has not been subject to any edits since the time that it was made.

- see Gwozdowski, ibid.
Thing to be Used to Refresh Memory
The tool used to jog the memory can be anything (a sound, a picture, a smell, etc). The trigger is not significant.
Any type of document may be used to refresh a witness's memory. It does not have to be a document written by the witness at all.
Even evidence that would not be admissible for reasons including that it was obtained through a Charter violation, may still be used to refresh memory.
Memory can be refreshed by any document. It does not matter weather than witness was the author.
There is nothing necessarily wrong with officers reading the statements of other witnesses as long as no coaching is involved.
Traditionally, counsel can refresh memory of a witness who is forgetful due to the span of time or "timidity".
An officer does not have to maintain possession or control over his notes that he uses to refresh his memory.
Even notes that are not accurate can be used as an aide-memoire.
Timing of the Creation of Document
The document need not have been made contemporaneously with the facts recorded in it.
Requirement to Produce
The record being used to refresh a witness's memory must be produced to the other side.
Where the accused is testifying, any record relied upon by a defence witness that is used as memory refresh must be produced to the Crown. Using interview notes for memory refresh will constitute a waiver of litigation privilege.

While as a general rule the document being used to revive the memory should be disclosed to the other side, this is not necessary in the case of a statement generated by the accused. So a statement made by the defence that is protected by solicitor-client privilege is not disclosable to the crown. If however the statement was purely created as a aide memoire then it may not be privileged. It is normally desirable for defence to make the purpose of the document clear on the document itself.
Privilege in a document will remain in place even at the time that it is used in court to refresh a memory.
Defence witness statements by non-accused persons are not generally protected by solicitor-client privilege.

Reliability of Refreshed Memory
The credibility and reliability of refreshed testimony is determined by the trier-of-fact.
Opposing counsel may cross-examine on the timing, reliability of the refreshing process as well as question whether the witness "had a present memory of events about which she testified."
The court must be cautious when a witness is using documents to refresh their memory. Where the witness is relying too much on the notes for their testimony there is a likelihood that they are not testifying to their memory and are simply reciting their notes.
Where officers collaborate on their notes that they refer to decreases the likelihood that the officer is actually refreshing their memory. This will inevitably go to the officer's credibility.

The procedure to refresh memory in the context of a prior recorded statement reduced to writing is as follows:
- on direct examination, counsel should put the statement in the hands of the witness
- counsel should direct the witnesses attention to the part which contains the previous answer
- the witness should read it to himself
- the counsel may put questions to the witness referring to the previous answer. The witness may correct an error, agree or deny the contents of the document
The most important element is to ensure that the evidence is the recollection of the witness and not the past recollection found in the document.
Certain courts found that it is not necessary to exhaust the memory before permitting refreshing it.
It does not matter how long before trial the witness used the document to refresh his memory. Such things can be cross-examined upon and will go to weight.
Generally speaking, statements should not be read in the presence of the any other witness.
The "thing" used to refresh memory should not be put in as an exhibit as it is not evidence.
There is some division on whether the witness only needs to produce his notes when he requires them to be refreshed.

Using a Prior Transcript to Refresh Memory (Coffin Application)
Where a witness honestly forgets or cannot remember certain information that has been previously recorded under oath or in a written statement, counsel may show a copy of the previous statement to refresh the witness's memory.
The ability to refresh the witnesses memory is at the discretion of the judge.
A witness should not be permitted to refresh memory from a prior statement where the witnesses is merely being evasive.The preferred route would be through a s.9(2) Milgaard application.
In such circumstances where the questioning on a prior statement is not for the purpose of discrediting or contracting the witness, which would engage s. 9 of the Canada Evidence Act, "the court has a discretion... to relax [the rule when] it is considered necessary in the interest of justice."
