General Principles

See also: Privilege

Spousal competency, compellability and privilege are "distinct but related concepts."[1] The purpose of all of these rules is to "protect marital harmony" and avoid having a spouse testify against another.[2]

Spousal Competence

See also: Competence and Compellability

There are two exceptions to the common law rule against spousal competence. There is a common law exception and a statutory exception.[1] In addition, spouses are permitted to testify for the defence.[2]

Common law rule of spousal competence

At common law a spouse of an accused is incompetent to testify except where the charge involves the person, liberty, or health, of the spouse.[3]

Evidence Act rule of spousal competence

Section 4(2) of the Canada Evidence Act modifies the common law by stating that:

4
[omitted (1)]

Spouse of accused

(2) No person is incompetent, or uncompellable, to testify for the prosecution by reason only that they are married to the accused.
[omitted (3), (4), (5) and (6)]
R.S., 1985, c. C-5, s. 4; R.S., 1985, c. 19 (3rd Supp.), s. 17; 2002, c. 1, s. 166; 2014, c. 25, s. 34, c. 31, s. 27; 2015, c. 13, s. 52.

CEA (CanLII), (DOJ)


Note up: 4(2)

It remains unsettled whether a witness who is competent under s. 4(2) is compellable.[4]

Common law partners

There is some suggestion that the rule of spousal privilege does not apply to those in common law relationships.[5] However, it has also been said that where there exists a "marital bond ...in substance", then the immunity will apply.[6]

Competence for Defence
Accused and spouse

4 (1) Every person charged with an offence, and, except as otherwise provided in this section, the wife or husband, as the case may be, of the person so charged, is a competent witness for the defence, whether the person so charged is charged solely or jointly with any other person.

Failure to testify

(6) The failure of the person charged, or of the wife or husband of that person, to testify shall not be made the subject of comment by the judge or by counsel for the prosecution.
R.S., 1985, c. C-5, s. 4; R.S., 1985, c. 19 (3rd Supp.), s. 17; 2002, c. 1, s. 166; 2014, c. 25, s. 34, c. 31, s. 27; 2015, c. 13, s. 52.

There must be something more than an "off-hand reference" to the fact that the accused chose not to testify to engage the prohibition under s. 4(6).[7]

Spousal Privilege

Spousal privilege is a class protection of certain communications between husband and wife. It is a protection that is separate and apart from spousal competency.[1]

A spouse who is found to be competent and compellable may still invoke privilege to protect their communications.[2] The privilege belongs to the recipient spouse.[3]

This class of privilege does not exist at common law, but rather was created by way of s. 4(3) of the Evidence Act, which states:

4
[omitted (1) and (2)]

Communications during marriage

(3) No husband is compellable to disclose any communication made to him by his wife during their marriage, and no wife is compellable to disclose any communication made to her by her husband during their marriage.

[omitted (4), (5) and (6)]

R.S., 1985, c. C-5, s. 4; R.S., 1985, c. 19 (3rd Supp.), s. 17; 2002, c. 1, s. 166; 2014, c. 25, s. 34, c. 31, s. 27; 2015, c. 13, s. 52.

CEA (CanLII), (DOJ)


Note up: 4(3)

This protection in s. 4(3) is testimonial in nature and is designed to prevent compelled testimony. It does not protect the actual content of the communication.[4]

Purpose

The purpose of the protection is a) to promote marital harmony and (b) to prevent the "indignity" of having a spouse testify against their partner.[5]

Common Law Partners

Traditionally, spousal privilege had not applied to common law partners.[6]

Dissolution of Marriage

Where the relationship has dissolved, the privilege will dissolve with it.[7]

Ownership and Waiver

The privilege is owned by the potentially testify spouse and can be waived by them.[8]

Third Parties Testimony

Third parties may "testify to communications between husband and wife that were overheard, intercepted, or otherwise discovered."[9]

Wiretap

Pursuant to s. 189(6), any information collected by wiretap are subject to the same protections.
