Most people discover this requirement at the worst possible moment — usually when they walk into ServiceOntario to apply for their marriage licence, sometimes a few weeks before a wedding they have already planned, and the agent at the counter asks for documents they have never heard of. If you were divorced outside Canada, you cannot simply produce your foreign divorce decree and expect the Province to accept it. Ontario requires a separate authorization from the Office of the Registrar General before a marriage licence can issue, and that authorization depends on a written legal opinion from an Ontario lawyer confirming that the foreign divorce meets Canadian recognition standards.
This is not a pointless bureaucratic hurdle. A Canadian marriage performed while one of the parties is still considered married to someone else would be void, and the consequences — for the new spouse, for children, for immigration, for inheritance — are serious. The opinion letter exists to give the Registrar General confidence that the previous marriage is properly ended before authorizing a new one.
The legal test — section 22 of the Divorce Act
Canadian recognition of foreign divorces is governed principally by section 22 of the federal Divorce Act:
"A divorce granted… by a competent authority shall be recognized for the purpose of determining the marital status in Canada of any person if either former spouse was habitually resident in the country or subdivision of the competent authority for at least one year immediately preceding the commencement of proceedings for the divorce." Divorce Act, R.S.C. 1985, c. 3 (2nd Supp.), s. 22(1)
Read plainly: if you or your former spouse lived in the country that granted the divorce for at least a year before filing for divorce there, Canada will recognize the divorce. This is the most common path to recognition. A divorce granted in the United States, the United Kingdom, Australia, India, the Philippines, or any other jurisdiction where at least one of the former spouses was ordinarily resident for a year before filing will almost always satisfy the test.
The common-law alternative — real and substantial connection
Section 22 is not the only route to recognition. Subsection 22(3) specifically preserves "any other rule of law respecting the recognition of divorces granted otherwise than under this Act," which means the common-law doctrine of real and substantial connection still applies in addition to the statutory test. This doctrine originated in the House of Lords decision in Indyka v. Indyka, [1969] 1 A.C. 33, and has been adopted and refined by Canadian courts over the decades since.
Under the real and substantial connection test, a foreign divorce can be recognized even where neither spouse satisfied the full one-year residence requirement of section 22, provided there is a meaningful connection between at least one of the parties and the jurisdiction that granted the divorce. Factors that Canadian courts have considered include substantial periods of residence short of a year, significant family ties to the jurisdiction, nationality, domicile, the location of marital property, and where the marriage was celebrated.
In practice, most opinion letters rely on the section 22 residence test because it is simpler to document and more predictable. The real and substantial connection test is the fallback where the facts do not fit neatly within section 22.
Divorces that will not be recognized
Not every foreign divorce can be recognized. The types of foreign divorces that Canadian courts have refused to recognize, or that opinion letters will decline to endorse, typically include:
- "Quickie" divorces where neither spouse lived in the jurisdiction, obtained through countries that advertise divorce services to non-residents.
- Mail-order divorces where there is no genuine court proceeding and no jurisdictional basis.
- Divorces obtained by fraud, or where the respondent spouse was not given proper notice of the proceeding — a violation of natural justice.
- Religious-only divorces that do not amount to a civil divorce in the country where they were pronounced.
If your divorce falls into one of these categories, the honest answer from any Ontario lawyer is that an opinion letter will not be possible, and a Canadian divorce proceeding may be the practical path forward. Finding this out early matters.
What the opinion letter actually does
The letter is a formal written legal opinion, prepared on the lawyer's letterhead, addressed to the Office of the Registrar General of Ontario. It sets out:
- The identity of the parties to the former marriage and the date and place of that marriage;
- The date and place of the foreign divorce, and the court or competent authority that granted it;
- The factual basis for recognition — typically, that one of the former spouses was ordinarily resident in the granting jurisdiction for at least one year preceding the proceedings;
- The legal analysis concluding that the divorce should be recognized in Ontario; and
- The lawyer's opinion that the applicant is free to remarry in Ontario.
The letter is signed by the lawyer, typically includes the lawyer's LSO number, and is submitted by the applicant to the Office of the Registrar General along with the other marriage licence application materials.
What you need to provide
To prepare the opinion letter, your lawyer needs:
- The original or court-certified copy of the divorce decree. A photocopy or scan is not sufficient; the Registrar General requires documents certified by the court that issued them.
- A certified translation, if the divorce decree is not in English or French. The translator must be a certified Canadian translator or, in some cases, the translation must be sworn by affidavit.
- The Ontario Application for Marriage (the marriage licence application) — both parties' portions.
- A brief written statement — often just a sentence or two — setting out where each former spouse resided in the year preceding the divorce. This establishes the jurisdictional basis.
- Photo identification for the person whose divorce is at issue.
Where the divorce decree is missing or cannot be obtained, we discuss alternatives: a fresh certified copy from the issuing court, or in some cases a court-issued certificate confirming the divorce. Where residence is harder to prove — for example, where the person moved frequently in the relevant year — the real and substantial connection analysis may be used instead.
The timing — plan at least a month ahead
The opinion letter itself can often be produced within a few business days once the documents are in hand. The bottleneck is the subsequent Registrar General review: after you submit the opinion letter together with your marriage licence application to the Office of the Registrar General, the Province takes approximately four weeks to review the package and issue the Authorization to Remarry.
Once the Authorization is issued, it is valid for ninety days. Within that window, you can apply at any ServiceOntario location for your marriage licence, which itself is valid for ninety days from the date of issue. The practical implication: if your wedding is less than six weeks away and you have not yet started this process, the timeline is tight. If your wedding is less than a month away, you are at risk of the Authorization not arriving in time. Start as early as you can.
Immigration considerations
Recognition of a foreign divorce matters for reasons beyond remarriage. If you are a permanent resident or Canadian citizen seeking to sponsor a new spouse under Canadian immigration law, the validity of your divorce from a previous marriage will be relevant. A divorce that Canada does not recognize means that, in Canadian law, you are still married — and you cannot sponsor a new spouse while married to someone else. Obtaining the opinion letter early also insulates against these downstream issues.
The cost
A foreign divorce opinion letter is a flat-fee service at most Ontario firms that offer it. The fee reflects the focused nature of the work: the document review, the legal analysis, and the drafting of the letter itself. It is not a litigation engagement and does not typically require ongoing hours. We provide a written quotation before any work commences.
This article is general information only and does not constitute legal advice. Whether a particular foreign divorce will be recognized in Ontario depends on the specific facts of that divorce — the jurisdiction, the residence of the parties, the procedural history, and the form of the decree. If you were divorced outside Canada and plan to remarry in Ontario, retain an Ontario lawyer to review your documents well before your wedding date.
