Common-Law Partner Sponsorship Canada

Written and reviewed by Omer Khalil, RCIC (R710149), a Regulated Canadian Immigration Consultant and member of the College of Immigration and Citizenship Consultants (CICC). Last reviewed: September 2026. On 18 September 2026 this page was re-checked against three IRCC pages on canada.ca plus the current IMM 5533 relationship-proof checklist: Who you can sponsor, Sponsorship eligibility, What it means to be a sponsor, and the checklist’s proof-of-relationship section. All matched, including the 12 consecutive months of cohabitation with only short and temporary absences, the minimum age of 18, the conjugal partner’s one year of exclusive and mutually interdependent relationship, the rule that a permanent resident living outside Canada cannot sponsor while a Canadian citizen abroad may if they will live in Canada, and the 3-year undertaking outside Quebec.

If you and your partner have lived together but are not married, you may be able to sponsor them through common-law partner sponsorship. This is part of Canada’s family class. It is evidence-heavy because IRCC must be satisfied that the relationship is genuine and that the couple lived together for the required period. This page explains who qualifies, the 12-month cohabitation rule, what proof helps, and how to reduce the risk of a refusal. Every relationship is different, so the safest first step is a review with a licensed RCIC.

What is common-law partner sponsorship?

Common-law partner sponsorship lets an eligible Canadian citizen, permanent resident, or person registered under the Indian Act sponsor a partner they are not married to, as part of Canada’s family class. The key difference from marriage-based sponsorship is that you prove your relationship through a shared life and a period of living together, rather than a marriage certificate. It can lead to permanent residence for your partner if the application is approved.

The 12-month rule. Common-law partner sponsorship requires at least 12 months of continuous cohabitation in a conjugal relationship. Short, temporary absences may be acceptable, but long separations can create problems.

Who qualifies as a common-law partner?

To be sponsored as a common-law partner, your partner generally must be someone who is not legally married to you, is at least 18, and has lived with you continuously for at least 12 months in a genuine, conjugal relationship. Common-law partners can be of any gender. The relationship must be genuine and not entered into mainly to obtain permanent residence.

The 12-month cohabitation rule

Common-law status is built on living together continuously for at least one year. “Continuously” means you maintained a shared home for that period. Short, temporary absences for work, business, or family reasons can be acceptable, but long separations can raise questions and may break the 12-month period. If you had time apart, be ready to explain the timing and the reasons clearly.

If you stopped living together, timing and reasons matter. Short, explained absences may be acceptable; long separations need careful handling.

What evidence can support a common-law relationship?

IRCC’s current guidance lists examples of proof that may help establish a common-law relationship, including shared residential property, joint leases or rental agreements, shared utility accounts, important documents showing the same address, identification documents and insurance. IRCC also says applicants do not need to include every listed item and that other proof may be considered. The applicable document checklist controls what must be submitted for the file.

MAK review framework, not an IRCC evidence quota. The purpose is to reconcile the claimed cohabitation period and the supporting record, not to manufacture one document for every month.

How the current IMM 5533 checklist structures relationship proof

For applicants who are currently living together, IRCC’s current relationship-proof checklist asks for at least two sets of cohabitation documents from the listed categories. These include joint residential property, a rental agreement showing both partners as occupants, joint utility or financial accounts, vehicle insurance showing the same residence, government-issued documents showing the same address, or other documents issued to each partner showing the same address.

If you cannot provide documents from at least two of those sets, IMM 5533 provides a specific alternative: submit a detailed written explanation of why the listed records are unavailable and provide any other cohabitation evidence you have. That makes the issue a documentation-and-chronology problem to explain honestly, not a reason to invent joint records after the fact.

If you are not living together when the application is filed, the checklist asks for proof of ongoing contact and proof of the sponsor’s visits; where there were no visits, it directs applicants to explain that in IMM 5532. The underlying common-law definition still requires at least 12 consecutive months of prior cohabitation in a continuing conjugal relationship.

Sponsor eligibility

To sponsor a common-law partner, you generally must be at least 18 and be a Canadian citizen, a permanent resident, or a person registered under the Canadian Indian Act. You usually need to be living in Canada. A Canadian citizen living abroad may sponsor if they can show they will live in Canada once their partner becomes a permanent resident. A permanent resident living outside Canada cannot sponsor. You also sign an undertaking to support your partner financially. For a spouse, common-law partner, or conjugal partner, the undertaking is 3 years outside Quebec. Quebec has its own undertaking rules. You may not be eligible if, for example, you are in default on a previous undertaking, or are receiving social assistance for a reason other than a disability.

Applicant eligibility and admissibility

Your partner must be in a genuine relationship with you and must be admissible to Canada. Depending on the case, this can involve medical, security, and background requirements. IRCC also assesses whether the relationship is genuine and ongoing. Honest, well-documented applications that match the facts are the most reliable way to address these requirements.

Inland vs outland common-law sponsorship

You will often hear sponsorship described as inland or outland. Inland usually refers to the spouse or common-law partner in Canada class, where your partner is in Canada with you. Outland usually refers to the family class processed through a visa office, often used when your partner is outside Canada. The right route depends on the facts of your case, including where your partner lives and whether they want to work in Canada while waiting. For married couples, see RCIC representation for common-law and spousal sponsorship.

Common-law sponsorship and open work permits

Some common-law partners sponsored from inside Canada may be eligible for an open work permit after an Acknowledgement of Receipt, depending on their status, location, relationship facts, and IRCC’s current instructions. Whether it applies to you depends on your specific situation, so confirm before relying on it. Learn more on our Spousal Open Work Permit page, which also covers sponsored common-law partners.

Common reasons common-law applications run into problems

Applications often run into trouble when the couple cannot clearly show 12 months of continuous cohabitation, when the proof is thin or all from one short period, when there were long separations that are not explained, or when documents do not match (different addresses, gaps in dates). A past refusal, prior immigration history, or limited paperwork makes careful preparation even more important. These are common examples, not a judgment on your relationship.

If there is immigration history, a prior refusal, divorce, long separation, or limited documents, do not guess. Get a file review.
