In Ontario family court, you cannot “plead the Fifth” because the Fifth Amendment is strictly an American law. Under Canadian law, you are generally forced to answer difficult questions during a family law proceeding, but you can invoke Section 5 of the Canada Evidence Act to prevent those answers from being used against you in a future criminal trial.
We have all seen American television shows where a witness boldly declares, “I plead the Fifth!” to avoid answering a question. Because of this, many people in Toronto, Ottawa, and Mississauga walk into their family law disputes believing they have the right to stay completely silent to avoid incriminating themselves. Whether the issue involves hidden income, unpaid taxes, or allegations of domestic behaviour, staying silent is not an option in Canada. 📺
Ontario family law operates on a principle of full and frank disclosure. If you refuse to answer relevant questions about your finances or your parenting time, the judge can draw a negative inference against you, strike your pleadings, or even hold you in contempt of court. However, the Canadian justice system does not want to force you into a criminal conviction just because you are going through a divorce. Understanding how to navigate this delicate balance requires the guidance of a skilled family law firm.
Step-by-Step Process for Questioning in Ontario
In an Ontario family law case, you will likely face formal questioning (also known as discoveries or cross-examination). If you are worried about criminal exposure, such as tax evasion with the CRA or a pending assault charge, you must follow a highly specific legal process.
Step 1: Understand the Compulsion to Answer
Under the Ontario Family Law Rules, you cannot simply cross your arms and refuse to speak. If a question is relevant to the divorce, child support, or spousal support, you are legally compelled to answer it. If you refuse, the opposing lawyer will file a motion, and a judge at the Superior Court of Justice will officially order you to answer.
Step 2: Object on the Record
Before you answer a dangerous question, your lawyer must clearly state on the record that you object to answering on the grounds that it may incriminate you. This is the crucial moment where you formally seek the protection of the Canada Evidence Act and the Ontario Evidence Act. 📝
Step 3: Invoke the Canada Evidence Act
Instead of pleading the Fifth, your lawyer will state that you are answering the question under the strict protection of Section 5 of the Canada Evidence Act. This creates a legal shield. It means that while you must confess the truth right now in the family law boardroom, the Crown Attorney or the police cannot use this specific transcript as direct evidence to convict you in a separate criminal trial later.
Step 4: Answer Truthfully
Once the protection is invoked and on the court reporter’s transcript, you must answer the question completely and honestly. Lying under oath is the criminal offence of perjury. Even with the protection in place, if you lie, that protection vanishes for the purpose of a perjury prosecution. 👤
Step 5: Prepare for Independent Investigations
You must understand the limits of this protection. While the police cannot use your direct words from the family court transcript against you, the opposing party can still tip off the police or the CRA. The authorities can then launch their own independent investigation to find other evidence against you.
How Much Does it Cost in Ontario? 💰
Defending yourself in a high-conflict family law case involving potential criminal issues is expensive. As of May 2026, here are the expected costs:
- Lawyer Fees: Having a senior family lawyer present to protect your rights during questioning generally costs between $350 and $700+ CAD per hour.
- Court Reporter Fees: Renting the boardroom and hiring a certified court reporter to transcribe the questioning usually costs $500 to $1,200 CAD per day, typically paid by the party asking the questions.
- Criminal Defence Consultation: If your answers involve criminal exposure, you should also consult a criminal defence lawyer beforehand, adding a one-time consultation fee of $300 to $500 CAD.
| Legal Concept | American System | Ontario (Canadian) System |
|---|---|---|
| Right to Silence | Fifth Amendment allows total refusal to answer. | No right to silence in civil/family court. Must answer. |
| Protection from Incrimination | Cannot be forced to testify against oneself. | Canada Evidence Act prevents answers from being used in criminal court. |
How Long Does the Process Take?
An official questioning session in an Ontario family law dispute typically takes 1 full day (usually 6 to 7 hours of active questioning). However, if you refuse to answer and the opposing lawyer must schedule a motion before a judge to compel your answers, the heavy backlog in the Ontario family court system means you could be waiting 3 to 6 months just to get a court date.
Frequently Asked Questions (FAQ)
Can I just refuse to show up for the questioning?
Absolutely not. Failing to attend a scheduled questioning in Ontario without a valid, court-approved excuse can result in your pleadings being struck, meaning you could automatically lose your family law case.
Will the CRA see my family court financial statement?
Family court files in Ontario are generally public records. While the CRA does not actively monitor every divorce, a disgruntled ex-spouse can legally send your sworn financial statements to the CRA to trigger a tax audit.
What if my answer proves I committed an indictable offence?
Even if the answer involves a serious indictable offence, you must answer if it is relevant to the family law case. The Section 5 protection will shield your testimony from being used in the criminal trial, but you should urgently consult a criminal lawyer.
Can the judge use my bad behaviour against me in the divorce?
Yes. While the criminal court cannot use your protected testimony, the family court judge absolutely can. If you admit to hiding money, the family court judge will use that admission to divide the assets heavily in your spouse’s favour.
