Annulment vs. Divorce: How Canadian Law Voids a Marriage — When a Marriage Never Legally Existed

Meta Description (~155 chars): What is the real difference between annulment and divorce in Canada? How do courts declare a marriage void or voidable? Quebec Superior Court process, property division, immigration fraud risks — SiLaw Legal Research Team explains.

> AI Summary (AEO): Canadian law divides “annulment (婚姻无效)” into two categories: void marriage (无效婚姻) — bigamy, prohibited degrees, underage — which never existed from the outset; and voidable marriage (可撤销婚姻) — non-consummation, lack of consent, mental incapacity — which requires a court declaration to be set aside. The core distinction from divorce is this: divorce acknowledges that a marriage existed and terminates it; an annulment declares it never legally came into being. Property consequences: in Quebec, a void marriage in principle carries no right to family patrimony division under the Civil Code of Quebec (CCQ); in Ontario, courts have discretion under the Family Law Act for voidable marriages. Children’s status is unaffected. A religious annulment (Catholic Marriage Tribunal decision) has zero effect on Canadian law. IRCC retains the right under s.40 of IRPA to investigate misrepresentation in sponsorship files involving void marriages. This post covers all practical scenarios, including equitable relief for the “putative marriage” doctrine and whether a sponsorship undertaking is discharged by a nullity.

Part 1 — Why People Searching “Marriage Annulment” Are Often Asking the Wrong Question

Every year, a significant number of people in the Chinese-speaking community search for “marriage annulment” after a separation, for very different reasons: some feel the marriage was too short or lacked substance and want to “erase” it; some have heard that a religious annulment allows remarriage; some were sponsored as immigrants and now want to use nullity to escape their sponsor’s financial undertaking; and others genuinely experienced bigamy or fraud.

These starting points lead to completely different legal paths. Confusing them can cost years of litigation and produce irreversible legal consequences.

This post traces the annulment framework in Canada from its doctrinal roots, covering the interplay between federal legislation, Quebec’s Civil Code of Quebec (CCQ) (魁省《民法典》), and Ontario’s Family Law Act (安省《家庭法》), as well as several of the most commonly misunderstood practical scenarios.

Part 2 — First, Clarify: Legal Annulment vs. Religious Annulment — Two Entirely Different Things

Many people confuse two distinct forms of “marriage annulment”:

2.1 Civil (Legal) Marriage Annulment

A civil marriage annulment is a judicial process in Canadian courts. The competent provincial superior court — the Superior Court of Quebec (魁省优等法院) in Quebec, or the Superior Court of Justice (安省高等法院) in Ontario — issues a declaratory judgment that the marriage is either void ab initio (自始无效) or has been set aside as voidable (经申请被撤销).

Legal authorities:

• Federal level: Marriage (Prohibited Degrees) Act, RSC 1985, c M-2.1; Divorce Act, RSC 1985, c 3 (2nd Supp) (note: the Divorce Act does not itself govern nullity, but the federal government holds exclusive legislative authority over “capacity to marry (婚姻的本质能力)”)
• Quebec: CCQ arts. 380–388 (requirements for marriage); CCQ art. 380 (action in nullity)
• Ontario: Common law tradition including Halpern v Canada (AG); Family Law Act (FLA), RSO 1990, c F.3, s. 1(1)

2.2 Religious (Catholic) Marriage Annulment

A “Declaration of Nullity (婚姻无效裁决)” issued by a Catholic Marriage Tribunal (天主教教廷裁判所) is a purely religious/ecclesiastical act. It determines that the parties never validly entered into a sacramental marriage in the eyes of the Church.

Key point: A religious annulment has absolutely no effect on Canadian law.

• A person who obtains a Catholic annulment decree remains legally married under Canadian law. To remarry (civil marriage), they must first obtain a civil divorce or a civil nullity declaration.
• Conversely, a Catholic who has already obtained a civil divorce but wishes to remarry within the Church must still apply for a Marriage Tribunal annulment — the two systems do not substitute for each other.
• Catholic annulment procedure: submit an application to the diocesan marriage tribunal, reviewed by a judicial vicar (canon lawyer priest); the process typically takes 12–36 months and may require witness testimony and psychological assessments.

Comparison	Civil (Legal) Marriage Annulment	Religious (Catholic) Marriage Annulment
Jurisdiction	Provincial superior court	Diocesan Marriage Tribunal / Roman Rota
Legal effect	Yes — changes the parties’ legal marital status	None — does not affect Canadian legal marital status
Property consequences	Governed by statute or judicial discretion	No legal property consequences whatsoever
Eligibility for civil remarriage	Possible immediately after declaration	Must still obtain civil divorce first
Eligibility for remarriage in the Church	Not applicable	Possible after the decree
Cost and timeline	Several thousand to tens of thousands CAD; months to years	Application fee usually lower; 12–36 months

Part 3 — Void Marriage vs. Divorce: The Essential Distinction at a Glance

Before drilling into the categories, here is the most fundamental comparison:

Legal concept	Divorce (离婚)	Annulment (婚姻无效)
Acknowledges the marriage existed?	Yes — acknowledges the marriage existed and terminates it	No — declares the marriage never existed, or has been set aside
Federal authority	Divorce Act	Common law + provincial statute
Precondition	Breakdown of marriage (1-year separation, adultery, physical/mental cruelty)	Specific grounds for nullity (detailed below)
Separation requirement	Usually 1 year (most common ground)	None — establishing a nullity ground is sufficient
Length of marriage	No restriction	No restriction — but shorter marriages can make certain grounds easier to prove
Property division	Full provincial family property legislation applies	Partially restricted (varies significantly by province)
Spousal support	Generally available	Generally unavailable (no marriage = no obligation)
Effect on children	None (independent of marriage validity)	None (children’s legal status is protected)
Eligibility for remarriage	After the divorce order takes effect	After the nullity declaration (legally never married)

—

Part 4 — First Category of Void Marriage: Void ab Initio (自始无效)

A void ab initio marriage never existed at law. In theory, the parties do not need any court proceeding to assert the nullity — the marriage was void from the moment it was purportedly solemnized. In practice, however, obtaining a court declaration remains critically important: to prove eligibility for remarriage, to clear property records, and to address immigration documentation.

4.1 Bigamous Marriage (重婚)

Sections 290–291 of the federal Criminal Code (联邦《刑法典》) make bigamy a criminal offence (maximum five years’ imprisonment). Where one party enters into a new marriage while a prior marriage remains undissolved, the second marriage is void ab initio.

Practical notes:

• The prior marriage may have been solemnized in any country that Canada recognizes
• Chinese divorce notarial certificates and court judgments must be certified before they can prove dissolution of a prior marriage
• If a prior spouse was declared dead but was in fact still alive, the second marriage is also void (subject to the equitable “putative marriage (善意婚姻)” doctrine discussed in Part 7)
• Further reading: [Episode 8 — Bigamy and Cross-Border Marriage Recognition](../MD-8%20Bigamy%20Cross-Border/) contains a more detailed analysis of criminal and civil consequences

4.2 Prohibited Degrees of Relationship (禁止亲属关系)

The Marriage (Prohibited Degrees) Act lists the blood and affinity relationships that bar marriage.

Direct lineal relationships are permanently prohibited, whether by birth or adoption:

• Grandparent–grandchild; parent–child
• Siblings (full blood or half blood)
• Uncle/aunt–niece/nephew (federal law permits this, though some provincial ceremonial laws may still impose restrictions)

Note: First cousins are permitted to marry under Canadian federal law — the Marriage (Prohibited Degrees) Act does not prohibit it — though certain religious traditions or cultural norms may take a different view.

Marriages contracted in violation of the prohibited degrees are void ab initio, and the parties may also be liable for incest.

4.3 Under Minimum Age (婚龄不足)

Capacity to marry falls within exclusive federal legislative jurisdiction. Following federal amendments in 2015, Canadian federal law no longer allows 16- or 17-year-olds to marry with parental consent, effectively raising the minimum age to 18 (some interpretations note there is no explicit statutory minimum and the common law is relied upon, but the dominant legislative intent is 18).

Underage marriages contracted in Canada after 2015 are generally declared void by the courts.

Where the parties married abroad, validity depends on:

1. Whether the lex loci celebrationis (law of the place of celebration) permitted marriage at that age
2. Whether recognition would violate Canadian public policy (public policy)

—

Part 5 — Second Category of Void Marriage: Voidable Marriage (可撤销婚姻)

A voidable marriage is treated as valid until it is set aside by a court. Only a qualifying party may apply for annulment; the marriage is dissolved only once the court makes its declaration (and the annulment typically takes effect retroactively to the date of the ceremony).

5.1 Non-Consummation / Impotence (无法完成婚姻消费)

This is one of the oldest nullity grounds inherited from the English common law tradition. The conditions are:

• An incapacity to consummate the marriage existed at the time of the marriage (impotence at the time of marriage)
• That incapacity continues at the time of the proceedings, or is incurable
• Sexual dysfunction that arises after marriage does not constitute a ground for nullity

This ground is extremely rare in practice, very difficult to prove, and courts approach it conservatively. Quebec’s CCQ theoretically recognizes it as well, but reported cases are scarce. Note: this is entirely distinct from a mutual agreement not to have sexual relations (e.g., certain special marriage arrangements) — the latter does not constitute a nullity ground.

5.2 Lack of Valid Consent (缺乏有效同意)

Marriage must be founded on the genuine, voluntary consent of both parties. The following circumstances may constitute nullity grounds:

5.2.1 Duress / Coercion (强迫 / 胁迫)

One party was compelled to enter the marriage by a substantial fear or threat. The legal standard:

• The threat must be sufficient to “overbear the will (压制意志自由)”
• Family or cultural pressure alone is insufficient to constitute legal duress (but may be used as contextual evidence)
• The threat need not come from the other spouse — threats by parents or third parties can suffice
• Leading case: Szechter v Szechter [1971] (English authority, but cited in common law provinces)

5.2.2 Fraud / Mistake (欺诈 / 错误)

Not every form of fraud constitutes a nullity ground. Canadian law requires the mistake to be fundamental — going to the nature of the ceremony (婚姻本质) or the identity of the other party (对方身份):

• Believing the ceremony was an engagement or religious ritual when it was actually a legal marriage → may constitute nullity
• Being deceived about the other party’s occupation, wealth, nationality, or fertility → generally does not constitute nullity (courts are reluctant to turn marriage into a consumer contract)
• Not knowing one was signing a marriage certificate → may constitute nullity

In practice this ground is extremely difficult to establish: courts presume that a marriage freely entered into was done so with full knowledge and consent.

5.2.3 Mistake as to the Nature of Marriage (对婚姻性质的根本错误)

A party fundamentally misunderstood the legal significance of marriage (extremely rare; courts typically require a combination of cultural background, language barriers, and mental state factors).

5.3 Mental Incapacity (精神无行为能力)

At the time of the marriage ceremony, the party must have had the mental capacity to understand the nature of marriage and its consequences. The determinative moment is: the instant the ceremony was performed.

Factors courts consider:

• Whether the person understood that marriage is an exclusive, enduring union
• Whether the person understood spousal rights and obligations (fidelity, cohabitation, mutual support)
• Cognitive impairment, dementia, or severe mental illness that had already reached the point of “inability to understand” at the time of marriage may constitute grounds for nullity

Not every mental illness causes nullity — a person with a history of psychiatric illness may still have capacity to marry during a period of stability.

Quebec law: CCQ arts. 154–155 set out the general principles governing incapacity; Quebec courts apply this framework when assessing capacity to marry.

5.4 Intoxication (醉酒 / 药物影响)

Severe intoxication or drug impairment at the time of the ceremony that destroyed capacity to consent may theoretically constitute a nullity ground — but the practical threshold is extremely high:

• It must be proven that the person had completely lost the ability to understand what was happening (mere intoxication is insufficient)
• Successful cases are exceedingly rare
• Continuing to cohabit as spouses after sobering up may constitute ratification (追认) of the marriage, which will defeat the nullity application

Part 6 — How to Apply for Annulment in Quebec

6.1 Court of Jurisdiction

The Superior Court of Quebec (魁省优等法院). A nullity application is an “action en nullité de mariage (婚姻关系无效之诉)” brought pursuant to CCQ art. 380.

6.2 Who May Apply

• Void marriage: In principle, any person with a legal interest may apply for a declaration, including the parties themselves, a former spouse, or children (in a bigamy case)
• Voidable marriage: Generally only the parties to the marriage themselves may apply (to protect personal autonomy); for certain grounds, only the “innocent party” may bring the application

6.3 Overview of the Procedure

1. Draft the originating application (Demande introductive d’instance): Set out the grounds for nullity, supporting facts, and the relief sought
2. Service (Signification): The other spouse must be formally served
3. Disclosure and evidence: Submit the marriage certificate and relevant supporting documents; depending on the grounds, submit witness statements, medical records, communications, etc.
4. Hearing (Audience): Parties and witnesses testify; the nullity grounds must be established on a balance of probabilities (优势证据标准)
5. Court judgment (Jugement): The court declares the marriage null; the declaration is registered with the Director of Civil Status (Directeur de l’état civil)

6.4 Evidence Requirements (by Ground)

Ground	Key types of evidence
Bigamy	Marriage certificate for prior marriage + proof of dissolution (or proof it was not dissolved); immigration records
Prohibited degrees	Relationship documents (birth certificates, DNA report)
Duress / coercion	Witness testimony; communications records; police reports; psychological assessment
Mental incapacity	Psychiatric / neurological medical records; physician’s diagnosis at time of ceremony; witness testimony
Fraud / mistake	Communications records; written statements; documents proving the other party’s identity
Non-consummation	Medical expert report

6.5 Timeline and Costs

• Uncontested proceeding: approximately 6–18 months; legal costs approximately $3,000–$8,000 (legal fees + court fees)
• Contested proceeding: may extend to 2–5 years; costs can reach tens of thousands of dollars
• Reminder: Quebec legal aid (aide juridique) covers applicants who meet the income threshold

Part 7 — Equitable Relief: The Putative Marriage Doctrine (善意婚姻原则)

7.1 What Is a Putative Marriage

When a marriage is declared void ab initio on nullity grounds, but at least one party entered the marriage in good faith (bona fide) and without knowledge of the nullity ground, that party may invoke the equitable protection of the “putative marriage (善意婚姻)” doctrine in certain provinces.

7.2 Quebec: CCQ Art. 385

CCQ art. 385 expressly provides:

> Even if a marriage is dissolved by reason of nullity, if one of the spouses contracted it in good faith (bonne foi), the provisions relating to the effects of marriage continue to apply in that spouse’s favour until the date of dissolution.

Practical effect: the good-faith spouse may claim family patrimony (patrimoine familial) division and spousal support as though the marriage had been legally valid. The bad-faith party who knew of the defect does not enjoy this protection.

7.3 Common Law Provinces (Ontario, etc.)

Common law provinces have no statutory putative marriage provision, but courts provide relief through equitable principles and the law of unjust enrichment (不当得利):

• Ontario’s Family Law Act, s. 1(1)’s definition of “spouse” may be extended by courts
• The unjust enrichment framework established in Kerr v Baranow, 2011 SCC 10 — developed for cohabitation relationships — can equally support property claims by the weaker party in a void marriage

—

Part 8 — Comprehensive Comparison of Legal Consequences: Void Marriage vs. Divorce

8.1 Property Division

Province / situation	Property consequences after divorce	Property consequences after marriage annulment
Quebec — void marriage (both parties knew)	CCQ family patrimony regime applies (CCQ arts. 414–426)	Does not apply: the marriage never existed; there is no family patrimony to divide
Quebec — void/voidable, good-faith party	N/A	CCQ art. 385: good-faith party retains family patrimony protection (until date of dissolution)
Quebec — void, both parties unaware	N/A	Both parties may invoke CCQ art. 385 protection
Ontario — voidable marriage	Family Law Act (FLA) applies in full	Court has discretion (s. 54 FLA): may order that FLA property rules apply if equity requires
Ontario — void marriage	N/A	FLA generally does not apply; constructive trust claims based on unjust enrichment are available
BC	Family Law Act (BC) applies	Similar to Ontario; courts have a degree of discretion

Important warning — the “ownerless property trap” in Quebec void marriages:

Where both parties acted in bad faith (both knew of the nullity ground), property accumulated jointly during the purported marriage may be impossible to divide through family property mechanisms. The parties must rely on:

1. Unjust enrichment (enrichissement injustifié, CCQ arts. 1493–1496): prove that one party was enriched by the other’s labour or contributions without just cause
2. Constructive trust or express trust (applicable where there is a written agreement)

8.2 Spousal Support

Principle: no marriage = no spousal support obligation.

After a nullity declaration, no spousal support right under the Divorce Act (联邦《离婚法》) generally arises, because the federal Divorce Act applies only to marriages that were legally valid.

Exceptions:

• Good-faith party (Quebec, CCQ art. 385): may claim support equivalent to what would have accrued during the marriage
• Long-term cohabitation: where the parties lived together as spouses for years regardless of marriage validity, Quebec law provides limited protection for de facto spouses; common law provinces may recognize “common-law partner (普通法伴侣)” status, which carries independent support rights
• Agreement: the parties may voluntarily enter into a separation agreement

8.3 Children’s Status (the Most Important Protection)

Children’s status is entirely unaffected, whether or not the marriage is valid.

Federal and provincial legislation across Canada expressly provides:

• Children born of a void or voidable marriage are fully equal in law to children born of a valid marriage
• Children’s inheritance rights, right to support, and nationality determination are unaffected by the validity of the marriage
• Parental obligations (custody, access, child support) continue to apply independently in annulment proceedings

Never forgo pursuing nullity out of concern that it will affect children’s status — the two are completely separate.

8.4 Immigration Consequences (IRCC / IRPA s. 40)

This is the area of greatest concern within the Chinese-speaking community, and the area with the most potentially fatal misconceptions.

Scenario 1: The sponsored person applies for marriage annulment, hoping to argue “we were never really married” to escape the sponsorship undertaking.

Conclusion: This will not work.

• The sponsor signed a sponsorship undertaking (担保承诺). That undertaking’s legal force is independent of the validity of the marriage.
• Even if a court subsequently declares the marriage null, if the sponsorship process was already completed (the sponsored person has permanent residence), the sponsor’s financial obligation (3 years or longer) remains fully in effect.
• The undertaking is a contract with the Canadian government and is not discharged by a change in private marital status.

Scenario 2: The sponsor discovers that the spouse had an undissolved prior marriage (bigamy); the marriage is void ab initio; the sponsor attempts to withdraw the sponsorship.

Conclusion: IRCC will conduct an independent investigation.

• IRPA s. 40 (misrepresentation / concealment (错报/隐瞒)): if the sponsorship application materials contained a false statement about the validity of the marriage, IRCC may find misrepresentation, which can result in removal of the sponsored person
• Even where the sponsor was deceived (innocent party), the sponsor must promptly disclose the situation to IRCC and cooperate with the investigation
• The sponsor may face a 5-year bar from sponsoring again (if found to have participated in fraud)

Scenario 3: Using marriage annulment to circumvent the “5-year bar on being sponsored as a spouse” waiting period.

Conclusion: Extremely high risk. Not recommended.

• IRCC officers are specifically trained to identify “strategic nullity applications”
• Applying for nullity and then quickly reapplying for sponsorship triggers heightened scrutiny
• If fraudulent intent is found, s. 40 may be triggered, resulting in permanent inadmissibility

Part 9 — Catholic Marriage Tribunal Annulment Process in Detail

For Catholic readers in the Chinese-speaking community, the religious annulment is a separate but important topic.

9.1 Why a Church Annulment Is Needed

• Catholic doctrine holds that a valid sacramental marriage is indissoluble
• A divorced Catholic who wishes to remarry in a Church ceremony must first obtain a Marriage Tribunal declaration of nullity for the prior marriage
• This is a parallel, independent process from the Canadian civil divorce

9.2 Common Church Nullity Grounds (overlapping with civil grounds, but broader)

• Lack of Due Discretion (Canon 1095)
• Psychic Incapacity to Assume the Essential Obligations of Marriage
• Exclusion of Children
• Exclusion of Fidelity
• Exclusion of Permanence
• Force and Fear (Canon 1103)

9.3 Procedure and Timeline

1. Initial consultation: consult with the tribunal’s judicial vicar to assess whether a viable ground exists
2. Submit the application (usually involves a fee, though waivers are available for low-income applicants)
3. Investigation of grounds: collect written testimony; both parties and witnesses may be interviewed
4. First-instance decision: typically 12–36 months
5. Appellate confirmation: a first-instance nullity decree must be confirmed by a second tribunal
6. Final approval by the Holy See (in complex cases)

To reiterate: all of the above proceedings have absolutely no binding effect on Canadian civil law.

Part 10 — Practical Scenario Analysis: When Is Annulment More Appropriate Than Divorce?

Scenario A: After the wedding, you discover the other party had an undissolved prior marriage (bigamy)

Recommendation: Apply for civil annulment (void marriage).

• Divorce is not available in this scenario (the marriage was never valid; there is nothing to “divorce”)
• Applying for a declaration of nullity clarifies your marital status on the record
• If there are children, handle custody and support arrangements concurrently

Scenario B: A hasty, extremely brief marriage (discovering incompatibility within weeks)

Recommendation: Almost always choose divorce (1-year separation), not annulment.

• A brief marriage does not constitute any nullity ground
• Attempting to seek annulment on grounds of “weak emotional foundation” will not succeed
• The most economical path is separation for one year followed by an uncontested divorce
• If there are no property disputes, consider a DIY divorce (unassisted divorce)

Scenario C: An arranged marriage / marriage compelled by family

Recommendation: Assess the duress evidence before deciding.

• If there was a substantial threat, physical control, and the will was genuinely overborne at the time, consider applying for annulment on grounds of voidability (duress)
• In practice, meeting the burden of proof is extremely difficult; apply for divorce concurrently as a fallback
• If personal safety is a concern, prioritize accessing a shelter and a protection order

Scenario D: For cultural or religious reasons, not wanting a “divorce” on record

Reality check: A civil annulment does not magically erase the marriage from the record — the marriage registration and the nullity declaration are both public records. Annulment is no more “dignified” than divorce. Those hoping to avoid the divorce label are typically disappointed.

Scenario E: Seeking annulment to escape debts or spousal support

High legal risk. Courts are highly alert to strategic nullity applications and may find an abuse of process, resulting in cost penalties.

—

Part 11 — Frequently Asked Questions (FAQ)

Q1: Is annulment faster and cheaper than divorce in Canada?

Usually not. Divorce (uncontested divorce after one year of separation) is typically the fastest path. An annulment requires proving specific statutory grounds; the burden of proof is on the applicant; and a contested nullity proceeding can take longer and cost more than a divorce. The annulment route should only be considered where the marriage genuinely has a nullity ground (e.g., bigamy).

Q2: I got married in China; after arriving in Canada I discovered my spouse deceived me (concealing children or debts). Can I apply for marriage annulment in Canada?

Concealing children or debts generally does not constitute fraud sufficient for nullity under Canadian law — courts require the mistake to be fundamental, going to the nature of the ceremony or the identity of the other party, not to personal qualities, financial status, or family background. These cases are better resolved through divorce, then seeking relief through property division. However, if the other party concealed an undissolved prior marriage (bigamy), that does constitute a void marriage.

Q3: After obtaining a marriage annulment, do I still need to go through divorce proceedings?

No. An annulment declaration and a divorce are mutually exclusive paths. The annulment terminates the marital relationship (or, in a void marriage, confirms it never existed), and no divorce is required.

Q4: We have children. Will applying for marriage annulment make them “illegitimate”?

Not at all. Legislation in every Canadian province expressly protects the legal status of children born of a void or voidable marriage. A child’s inheritance rights, right to parental support, and citizenship determination are unaffected by the validity of the marriage. The parents’ obligation to support the children does not disappear because the marriage is annulled.

Q5: A Catholic obtained a civil divorce and then applied for a Marriage Tribunal annulment decree. What is their legal status under Canadian law — married or divorced?

Divorced. A religious annulment decree has no effect whatsoever on Canadian law. The person’s legal status is determined by Canadian civil proceedings — having completed a civil divorce, they are legally divorced. The Marriage Tribunal decree affects only their status within the Church; it has no bearing on their legal status.

Q6: In a Quebec marriage annulment case, if I am the good-faith party who was deceived, can I still obtain a property division?

Yes. CCQ art. 385 expressly protects the good-faith party: even if the marriage is dissolved by reason of nullity, the good-faith party retains family patrimony (patrimoine familial) division protection, with the same effect as if the marriage had been valid throughout (up to the date of the nullity declaration). The key is that you must prove you did not know of the nullity ground at the time of the marriage.

Q7: My spouse was sponsored by me to come to Canada. I have now discovered that they concealed the fact that they still had a valid marriage in their home country (bigamy). What effect does marriage annulment have on my sponsorship undertaking?

Marriage annulment does not automatically discharge your sponsorship undertaking (担保承诺). The undertaking is a legal commitment you made to the Canadian government; it is legally independent of the validity of the marriage. You should immediately report the situation to IRCC, which will investigate pursuant to IRPA s. 40 to determine whether there was fraudulent misrepresentation. The sponsored person faces a risk of removal; you may also face further sponsorship restrictions. Please consult an immigration lawyer immediately.
