==General Principles==
A ''Voir Dire'' is a hearing to determine a question of law, including the admissibility of evidence.<Ref>
{{CanLIIRP|Sadikov|g2tgn|2014 ONCA 72 (CanLII)|305 CCC (3d) 421}}{{perONCA|Watt JA}}{{atL|g2tgn|30}} (A voir dire is to "determine the admissibility of evidence proposed for admission by a party to a criminal proceeding")<br>
</ref>
It is typically held during a trial but is considered a separate hearing from the trial itself. It is known as a "trial within a trial" and designed to determine an issue separate from the trial on matters of procedure or admissibility of evidence.

; Purpose
The fundamental purpose of a voir dire is to determine the admissibility of disputed evidence separate from the merits of the trial.<Ref>
{{CanLIIR|Wanihadie|jfvc4|2021 ABCA 173 (CanLII)}}{{AtL|jfvc4|11}} ("The fundamental purpose of a voir dire is to determine the admissibility of disputed evidence. This is distinct from assessing the merits of the case on consideration of all of the admissible evidence...")<br>
{{CanLIIRPC|Erven v The Queen|1mktn|1978 CanLII 19 (SCC)|[1979] 1 SCR 926}} at p 931{{fix}}
</ref>
The separation from the trial permits and exploration and testing of the evidence without affecting the integrity of the trial process.<Ref>

==Procedure==
The procedure in holding a voir dire is at the discretion of the judge based on the issue and nature of the "means of proof available".<ref>
{{CanLIIRP|Sadikov|g2tgn|2014 ONCA 72 (CanLII)|305 CCC (3d) 421}}{{perONCA|Watt J}}{{atL|g2tgn|32}}
</ref>

; Establishing Basis for Voir Dire
A party seeking a voir dire has an obligation to "demonstrate a reasonable basis for holding a voir dire". The trial judge is permitted to screen out application where "remedy cannot reasonably be granted".<ref>
{{CanLIIRx|Edwardsen|j1gtl|2019 BCCA 259 (CanLII)}}{{perBCCA|Harris JA}}{{atL|j1gtl|62}} ("the issue of whether a voir dire should be held is not simply a question of standing. In these circumstances, Mr. Edwardsen was required to demonstrate a reasonable basis for holding a voir dire. The purpose of a Vukelich hearing is to screen out proposed pre-trial applications where a remedy cannot reasonably be granted. Accordingly, the judge was entitled to take into account the likelihood of a remedy being granted on the substance of the application regardless of standing.")
</ref>

; Failure to Follow Procedure
The failure of holding a voir dire to determine if potentially inadmissible evidence should be heard will not not always be fatal to the trial. Where the evidence is still tested and there is no prejudice to the accused to may still be valid. The court must consider whether the process was followed that served the same purpose as the voir dire.<ref>
{{CanLIIRP|DAR|fqnc4|2012 NSCA 31 (CanLII)|994 APR 331}}{{perNSCA|Bryson J}}
</ref>

; Directed Verdict
There seems to be some ability to make a motion for "non-suit or directed verdict" motion by the responding party to a voir dire application.<ref>
{{CanLIIR-N|Gartland|, 1981 CarswellOnt 1845, 7 WCB 110 }}{{at-|26}} (the accused person must be afforded "every essential procedural step and safeguard available to him on his trial on the merits of the substantive offence, in so far as it can be applicable...") cited also in {{CanLIIRP|BT|frx58|2012 NSPC 59 (CanLII)|1010 APR 39}}{{perNSPC|Derrick J}}</ref>

; Jury Trials
A voir dire should always be held in absence of the jury.<ref>
{{CanLIIRP|Viszlai|ftnz7|2012 BCCA 442 (CanLII)|293 CCC (3d) 127}}{{perBCCA|Frankel J}}{{atsL|ftnz7|69| to 72}}
</ref> 
It is important that the jury not be told anything about the purpose of the voir dire or the result of the hearing.<Ref>
{{ibid1|Viszlai}}
</ref>

; Timing of ''voir dire''
It has been recommended that judges ruling on voir dires "should resist making final rulings until such time as they required to do so". As the trial progresses many issues may resolve themselves. However, where the "proposed evidence is likely to have a significant impact on the outcome of the
trial" then it should be dealt with early.

</ref>

; Multiple Void Dies
Each evidentiary issue should be treated as a separate voir dire and their evidence cannot be joined without consent.<ref>
{{supra1|Sadikov}}{{atL|g2tgn|31}}</ref>
That being said, particular pieces of evidence may raise multiple issues of admissibility and are usually treated together. Caution must be taken by the judge to ensure their ruling reflect "an informed understanding" of the governing law.<Ref>

==Types of Voir Dires==
===Applying Rules Evidence===
The judge must determine whether the "conditions precedent" to the admission of evidence have been met.<ref>
{{CanLIIRP|Sadikov|g2tgn|2014 ONCA 72 (CanLII)|305 CCC (3d) 421}}{{perONCA|Watt JA}}{{atL|g2tgn|30}}<br>
</ref>

===Constitutional Challenges to the Admissibility of Evidence===
The process of challenging the constitutionality of the admissibility of evidence requires first an inquiry into the constitutionality of the state's conduct and then second, should a finding of unconstitutionality is found, an inquiry into the "admissibility of the evidence obtained by the infringement".<ref>
{{CanLIIR|Sadikov|g2tgn|2014 ONCA 72 (CanLII)}}{{perONCA|Watt JA}}{{atL|g2tgn|35}}
</ref>

Provincial Rules of Court may also provide guidance on procedure.<ref>
e.g. Ontario: Rule 31 of the Criminal Proceedings Rules

====Challenging Warrant Validity====
{{seealso|Standard of Review of a Judicial Authorization}}

Procedurally, a voir dire on the for the validity of a warrant should proceed as follows:<ref>
{{CanLIIRP|Wilson|fllg6|2011 BCCA 252 (CanLII)|272 CCC (3d) 269}}{{perBCCA|Frankel JA}}{{atL|fllg6|69}}<br>
</ref>
:(a)      The trial judge should determine whether a voir dire is necessary and, if so, whether the calling of evidence should be permitted;
:(b)      If the judge accedes to the request to hold a voir dire and the accused wishes to cross-examine the informant, then the accused must obtain leave of the judge to do so. If the judge grants leave, then he or she can limit the scope of the cross-examination;
:(c)        Cross-examination should proceed to the extent permitted by the order granting leave;
:(d)      Re-examination, if any, should follow the cross-examination; and
:(e)      The trial judge should determine whether the record as amplified on the review could support the issuance of the warrant.

==Waiver==
A voir dire cannot be waived by mere silence of counsel.<ref>
{{CanLIIRPC|Powell v R|1z6fb|1976 CanLII 155 (SCC)|[1977] 1 SCR 362}}{{perSCC|De Grandpre J}}<br>
{{CanLIIRPC|Park v R|1txdg|1981 CanLII 56 (SCC)|[1981] 2 SCR 64}}{{perSCC|Dickson J}}<br>
</ref>

Unequivocal admission of the issue by an opposing party should generally be sufficient to forgo a voir dire.<ref>
e.g. {{CanLIIRP|Dietrich|g1bt2|1970 CanLII 377 (ON CA)|1 CCC (2d) 49}}{{perONCA|Gale CJ}}
</ref>
The judge should be be satisfied that counsel understood the matter and has made an informed decision.<ref>

==Voir Dire Evidence==
Charter applications require a factual record. They cannot be argued in a vacuum.<ref>
See {{CanLIIRPC|MacKay v Manitoba|1ft3c|1989 CanLII 26 (SCC)|[1989] 2 SCR 357}}{{perSCC|Cory J}}<br> 
{{CanLIIRPC|Danson v Ontario|1fst8|1990 CanLII 93 (SCC)|[1990] 2 SCR 1086}}{{perSCC|Sopinka J}}<br>
</ref>

There is no strict requirement in law that voir dires must be conducted on viva voce evidence.<ref>
{{CanLIIRP|Kematch|28cmh|2010 MBCA 18 (CanLII)|252 CCC (3d) 349}}{{perMBCA|Monnin JA}} <br>

</ref>
The court may, as a matter of efficiency and judicial economy, decide the issues on the basis of counsel summation of evidence.<ref>

</ref>

Affidavits that are based on hearsay should be given little weight and generally should not be considered admissible as evidence on a Charter application.<ref>

</ref>

Since evidence in a voir dire is separate and apart from evidence in the trial proper, each exhibit should be marked to be distinguished from the trial such as "V.D. Exhibit 1, etc".<Ref>
{{CanLIIRP|Grey|fxf9n|2013 BCCA 232 (CanLII)|338 BCAC 121}}{{perBCCA|Frankel JA}}{{atL|fxf9n|42}}<br>
</ref>

The accused can be cross-examined at trial on evidence that they gave during a voir dire.<ref>
{{supra1|Darrach}}</ref>
During the voir dire, he may be questioned on the truthfulness of a previous statement.<ref>

===Admissibility of Voir Dire Evidence Within the Trial===
A ''voir dire'' is considered a separate hearing and so evidence admitted in the ''voir dire'' is not automatically evidence in the trial proper.<ref>
{{CanLIIRP|Gauthier|1z6fj|1975 CanLII 193 (SCC)|[1977] 1 SCR 441}}{{perSCC|Pigeon J}} at 452<br>

</ref> 

The evidence heard in a voir dire can become evidence of the trial proper where it has been found admissible in the voir dire and both parties consent (known as a "blended" voir dire).<ref>
{{CanLIIRP|Jir|2d71m|2010 BCCA 497 (CanLII)|264 CCC (3d) 64}}{{perBCCA|Frankel JA}}{{atL|2d71m|10}}<br> 
{{CanLIIRP|Ballendine|fl8xf|2011 BCCA 221 (CanLII)|271 CCC (3d) 418}}{{perBCCA|Frankel J}}{{atL|fl8xf|84}}<br>
{{supra1|Dela Cruz}}{{atL|1rb9k|26}}<br>
</ref>

Consent for a blended voir dire can be applied only to some of the evidence to the exclusion of the rest of the evidence heard.<Ref>
e.g. {{CanLIIR|Smith|gtrdb|2016 BCSC 1725 (CanLII)}}{{perBCSC|Kent J}}{{atsL|gtrdb|45| to 47}}<br>
</ref> 

However, where there has been evidence accepted at the voir dire that would otherwise be inadmissible at trial, and which was consented as applicable to the trial, the validity of the verdict may be in question.<ref>
{{CanLIIRP|Wilson|fllg6|2011 BCCA 252 (CanLII)|272 CCC (3d) 269}}{{perBCCA|Frankel JA}}{{atL|fllg6|71}}<br>
</ref>

The choice of whether to consent to a blended voir dire will have an effect on the manner in which evidence is presented. A non-blended voir dire may require the defence to lead evidence to establish the violation. A blended voir dire will require the evidence to be lead by the Crown.<ref> See [[Charter Applications]] for details on burden</ref>
