How Long Is Common Law in Canada? The 12-Month Cohabitation Rule for Sponsoring a Partner (2026)

How long is common law in Canada for immigration purposes? You must have lived together for at least 12 consecutive months in a conjugal (marriage-like) relationship before you can sponsor your common-law partner for permanent residence. The 12 months must be continuous, with only short, temporary absences.

How the 12-month common-law rule works

For family sponsorship, a common-law partner is someone who is not legally married to you but has lived with you for at least 12 consecutive months. IRCC's official guidance defines this as living together continuously for one year in a conjugal relationship, without any long periods apart.

Two details trip people up. First, the year has to be continuous. You cannot add up several separate stretches of living together to reach 12 months. Second, short absences are fine: time spent away for family obligations or work and business travel is acceptable, as long as it was short and temporary and you kept a shared home. IRCC also notes that if either partner chooses to end the relationship, the relationship is considered over.

A common-law relationship can be with a partner of any gender.

Common-law partner Canada requirements: what IRCC checks

Beyond the 12 months of cohabitation, common-law partner Canada requirements include that your partner is not legally married to you, is at least 18 years old, is in a genuine relationship with you (not one entered into mainly to gain status), and is not inadmissible to Canada. If your application is approved, your partner can become a permanent resident of Canada.

You also have to qualify as a sponsor. To sponsor a partner you must be at least 18, be a Canadian citizen, a permanent resident, or a person registered under the Indian Act, and live in Canada (a citizen living abroad must show they plan to return when their partner becomes a permanent resident; a permanent resident living abroad cannot sponsor). In most cases there is no minimum income requirement to sponsor a spouse or partner. You may be barred from sponsoring in certain situations, such as if you were yourself sponsored as a partner and became a permanent resident less than five years ago, or if you are receiving social assistance for a reason other than a disability.

If you live in Quebec, the province sets its own sponsorship and income rules and you sign a separate undertaking with the Government of Quebec. Confirm the current Quebec requirements on the official provincial site before you apply, as Quebec periodically caps intake.

Proving you lived together: the documents that make or break a file

This is where most common-law applications are won or lost. IRCC accepts a combination of documents to prove at least 12 months of continuous cohabitation, including shared ownership of residential property, joint leases or rental agreements, bills for shared utility accounts (gas, electricity, telephone), and important documents showing the same address for both of you, such as driver's licences and insurance policies. You do not need every item, and IRCC may consider other proof as well. Send certified photocopies unless your checklist asks for originals, and use IRCC's document checklist to confirm what to include. The same evidence standard applies whether you choose inland or outland spousal and partner sponsorship.

From Amir's desk

In practice, the single most important thing for a successful common-law sponsorship is having multiple documents, across multiple account types, that show both of your names at the same address. Couples usually are not thinking about an immigration file from day one, so they often have only one name on the lease, the hydro account, the internet bill, or the bank account. That is the gap that sinks files. The officer has to be convinced of two separate things: that the relationship is genuine and that you actually lived together. The more evidence you have, spread across more types of documents, the stronger your case.

I have seen refusals where the only objective proof of cohabitation was a single cell-phone bill, the lease was signed by the sponsor but not the applicant, and the applicant's bank statements showed day-to-day spending far from the home they claimed to share. Officers notice that kind of contradiction. Get the applicant's name onto the lease and the core utility and bank accounts as early as you can, keep the address identical across every document, and make sure your financial activity is consistent with where you say you live.

What if you could not live together for 12 months?

If you are in a genuine, committed relationship but could not live together for a full year because of immigration, legal, or other serious barriers, IRCC has a separate category called the conjugal partner. A conjugal partner is in an exclusive, mutually interdependent relationship with you for at least one year, lives outside Canada, and could not live with you or marry you because of barriers such as marital status, sexual orientation, or persecution. This is a narrower category than common-law, and IRCC scrutinizes it closely, so it is worth getting advice before choosing this route.

If you are unsure whether your relationship qualifies as common-law, conjugal, or married, this is exactly the kind of question to settle before you file. Amir Ansari, RCIC, can review your living history and documents and tell you which category fits and what proof you are missing. You can book a consultation to map it out.

Why this matters for your immigration application

The 12-month rule is not a technicality. If you apply before you can show a full continuous year of cohabitation, or you cannot document it convincingly, the application can be refused, and a refusal costs you months and the government fees. A partner you sponsor from inside Canada may also be eligible for an open work permit while the application is in process, so getting the relationship category right early has practical benefits too. Couples in Metro Vancouver often share a place long before they marry, which can make common-law the natural route, but only if the paper trail keeps up with the relationship. Knowing exactly how long common law is in Canada, and starting to build joint documents early, is the difference between a clean approval and a returned or refused file.

Frequently asked questions: how long is common law in Canada

How long is considered common law in Canada?

For immigration sponsorship, you are considered common-law after living together for 12 consecutive months in a marriage-like relationship. Note that provincial laws (for taxes, benefits, or family property) can use different timeframes, so the federal 12-month immigration rule is specific to sponsorship.

Does the 12 months of cohabitation have to be continuous?

Yes. IRCC requires one continuous year of living together, without long periods apart. Short, temporary absences for family obligations or work and business travel are acceptable if you maintained a shared home.

What documents are required for a common-law partner in Canada?

A combination of proof showing the same address over 12 months: joint leases or property ownership, shared utility bills, and identity or insurance documents listing both names at one address. You do not need all of them, but more document types from more of the year make a stronger file.

Can you sponsor a common-law partner who lives in another country?

Common-law sponsorship still requires that you have already lived together for 12 continuous months. If you have never been able to live together because of serious barriers, the conjugal partner category may apply instead. Confirm which one fits your situation before applying.

Is there an income requirement to sponsor a common-law partner?

In most cases, no. There is generally no minimum income requirement to sponsor a spouse or partner. Income only becomes a factor in specific situations involving dependent children who have children of their own.

Every couple's living history is different, and the wrong category or a thin document set is a common reason files are returned. Amir Ansari, RCIC, works with couples across Vancouver, Burnaby, Surrey, and Richmond to build common-law and spousal sponsorship applications that hold up to officer scrutiny. Book a consultation to have your relationship evidence reviewed before you submit.
