Generally, under the Canada Evidence Act, the Crown cannot force your legally married spouse to testify against you in a criminal trial. However, there are major exceptions. If the charge involves domestic violence, threats against the spouse, or crimes against children, your spouse loses this privilege and becomes a compellable witness.
When a person is charged with a criminal offence in Canada, the Crown Prosecutor’s job is to gather witnesses to prove the case beyond a reasonable doubt. Often, the person who knows the most about the accused is their spouse. A common question in Canadian criminal law is whether a husband or wife can be forced to take the stand and testify against their partner.
The law governing this is found primarily in Section 4 of the Canada Evidence Act. It outlines the concept of “spousal privilege” and “spousal incompetence.” Historically, this rule existed to preserve marital harmony. However, modern Canadian law has carved out significant exceptions, particularly in cases of domestic abuse, ensuring that the privilege cannot be used as a shield to silence victims of family violence.
Step-by-Step Process: Understanding Spousal Compellability
Determining whether a spouse can be forced to testify requires a careful legal analysis of the relationship and the specific charges. Here is how the Canadian justice system assesses spousal testimony.
Step 1: Establishing Legally Married Status
Spousal privilege in Canadian criminal law only applies to legally married couples. Despite common-law couples having many identical rights in family and tax law, the Supreme Court of Canada has maintained that common-law partners do not benefit from spousal privilege in criminal trials. If you are common-law, your partner is fully compellable by the Crown, just like any standard witness.
Step 2: Assessing the Type of Offence
If you are legally married, the next step is examining the charge. If the charge is a standard property crime, fraud, or an assault against a stranger, the spouse is generally “incompetent” to testify for the Crown, meaning the Crown cannot call them to the stand. However, if the charge is assault against the spouse (domestic violence), or a sexual offence against a child, Section 4(2) of the Canada Evidence Act dictates the spouse is highly compellable.
Step 3: Invoking Spousal Communications Privilege
Even if a spouse chooses to testify voluntarily, or is compelled due to an exception, another layer of protection exists. “Spousal Communications Privilege” means that a spouse cannot be forced to disclose any private conversations that occurred between them during the marriage. This privilege belongs to the spouse testifying, and they can choose whether or not to answer questions about those private discussions.
Step 4: Subpoena and Court Attendance
If the Crown determines the spouse is compellable (e.g., in a domestic violence case), they will serve the spouse with a subpoena. The spouse must attend court. If they refuse to show up, the judge can issue a material witness warrant for their arrest. If they take the stand and refuse to answer questions, they could face contempt of court charges.
When is a Spouse Compellable?
| Scenario / Charge | Is the Spouse Compellable? | Reasoning under Canadian Law |
|---|---|---|
| Fraud or Theft (against a 3rd party) | No. | Standard spousal privilege applies to protect the marital bond. |
| Domestic Assault (against the spouse) | Yes. | Exception under the Canada Evidence Act to protect victims. |
| Common-Law Partner (Any charge) | Yes. | Privilege strictly extends only to legally married couples. |
How Much Does Independent Legal Advice Cost?
In cases where a spouse is unsure of their legal rights or fears self-incrimination, seeking Independent Legal Advice (ILA) from a separate lawyer is highly recommended.
- ILA Consultation: A one-hour session with a criminal defence lawyer for the spouse generally costs between $250 and $500 CAD.
- Court Representation: If the spouse needs a lawyer to fight a subpoena or argue against compellability in court, fees can range from $1,500 to $3,500 CAD.
- Note: The accused’s lawyer cannot legally represent or give advice to the spouse due to a strict conflict of interest.
How Long Does the Process Take?
Issues surrounding spousal testimony are usually resolved before the trial begins. A criminal case involving domestic charges can take anywhere from 6 to 18 months to reach a trial date. During this time, the Crown will typically reach out to the spouse to assess their willingness to testify. If compellability is disputed, the judge will hold a pre-trial hearing (a voir dire) to make a legal ruling, which usually adds a few days to the trial timeline.
Frequently Asked Questions (FAQ)
Can my spouse choose to testify against me voluntarily?
No, not generally. In standard cases where privilege applies (like fraud), the spouse is considered “incompetent” to testify for the Crown, meaning they cannot take the stand against the accused even if they are angry and want to do so voluntarily.
What happens if we get divorced before the trial?
If you are legally divorced by the time the trial occurs, the general spousal privilege is lost, and the ex-spouse becomes a compellable witness for the Crown. However, the “communications privilege” still protects private conversations that happened while you were married.
Can the Crown force a spouse to testify if they want to drop the charges?
Yes. In domestic violence cases, the decision to lay or drop charges rests entirely with the Crown Prosecutor, not the victim. Even if the spouse reconciles with the accused and wants to drop the charges, the Crown can legally subpoena them and force them to testify.
Does spousal privilege apply in Canadian civil courts?
In civil litigation (like a lawsuit over a contract), spouses are generally competent and compellable to testify against each other. However, they may still invoke spousal communications privilege to protect the private conversations held during their marriage.
