The section 4(5) exception preserves the common law rule.<ref>see {{CanLIIRP|MacPherson|gd524|1980 CanLII 2831 (NSCA)| (1980) 52 CCC (2d) 547 (NSCA)}}{{perNSCA|Macdonald JA}}<br>
{{CanLIIRP|Czipps|g131b|1979 CanLII 2095 (ON CA)|48 CCC (2d) 166}}{{perONCA|Morden JA}} (2:1)<br>

It can be invoked even where the witness spouse is not the victim but their health or liberty is threatened.<ref>
{{CanLIIRP|Schell|1h1fl|2004 ABCA 143 (CanLII)|188 CCC (3d) 254}}{{perABCA|Paperny JA}}</ref>

Thus, generally speaking spouse cannot testify on behalf of a co-accused or the crown. In civil trials, provincial evidence acts have removed these presumption, allowing spouses to testify in all circumstances.

The immunity is concern with the state of the relationship at the time of the evidence being given, and not at the time of the incident.<ref>
{{CanLIIRP|Lonsdale|fnwwl|1973 ALTASCAD 125 (CanLII)|15 CCC (2d) 201}}{{perABCA|Sinclair JA}} </ref>

The protection is only only those in a "valid and subsisting" marriage.<ref>
{{CanLIIRP|Salituro|1fshg|1991 CanLII 17 (SCC)|[1991] 3 SCR 654}}{{perSCC|Iacobucci J}}</ref>
Thus, the spousal exception does not survive the marriage. "Irreconcilably separated" spouses are not protected where there is no marital harmony to preserve.  Thus, spouses with "no reasonable prospect of reconciliation" is exempt from spousal immunity. This is determined objectively and on the balance of probabilities.<ref>
{{CanLIIRP|Jeffrey|2d9q3|1993 ABCA 245 (CanLII)|84 CCC (3d) 31}}{{perABCA|Picard JA}}</ref>. 

A spouse refers only to legally married spouses. 
Those who are: 
# common law<ref>
{{CanLIIRP|Martin|22rv8|2009 SKCA 37 (CanLII)|244 CCC (3d) 206}}{{perSKCA|Klebuc CJ}}<Br>

#separated short of divorce with no hope of reconciliation,
# divorced <br>
are not subject to the spousal immunity.

However, there is some authority suggesting that s. 4(1) and 4(3) must be read up to include common law partners anywhere there is reference to "husband" or "wife".<ref>
{{CanLIIRP|Masterson|24j5n|2009 CanLII 36305 (ON SC)|245 CCC (3d) 400}}{{perONSC| Hennessy J}}

A competent spouse for a party is necessarily a compellable witness.<ref>
{{CanLIIRP|McGuinty|1nppz|1986 CanLII 116 (YK CA)|27 CCC (3d) 36}}, ''per'' Lambert JA<br>
This however is not necessarily consistent with UK common law</ref>

Even where the witness spouse is competent to testify, this does not necessarily always remove spousal privilege. <ref>
{{CanLIIRP|Zylsatra|6jk6|1995 CanLII 893 (ON CA)|99 CCC (3d) 477}}{{perONCA|Trotter JA}}</ref> 
However, spousal privilege cannot apply where s. 4(2) is applied.<ref>
{{CanLIIRP|St. Jean|hv0zc|1976 CanLII 1344 (QC CA)| (1974) 32 CCC (2d) 438(QCCA)}}{{perQCCA|Kaufman JA}}</ref>

A wife who previously consented to a wiretap of conversations between her and her husband but then refuses to testify at trial may rely on spousal privilege s. 4(3) of the Evidence Act.<ref>
