Overview

What is common-law sponsorship in Canada?

Common-law sponsorship is a family sponsorship pathway for eligible couples who are not legally married but meet Canada's common-law relationship requirements. An eligible sponsor may be able to sponsor a qualifying common-law partner for Canadian permanent residence.

For immigration sponsorship, simply describing a relationship as common-law is not enough. The application must establish the required cohabitation period, show that the relationship is genuine and demonstrate that the sponsor and applicant meet the applicable immigration requirements.

Relationship requirement

When does IRCC consider a couple common-law?

For spouse or partner sponsorship, IRCC describes a common-law partner as someone who is not legally married to the sponsor, is at least 18 years old and has lived with the sponsor for at least 12 consecutive months in a conjugal relationship.

The 12-month period is based on continuous cohabitation. IRCC states that time spent apart during that period should be short and temporary, for example because of family obligations or work or business travel. Long periods apart can create an eligibility issue and should be reviewed carefully.

If one partner chooses to end the relationship, IRCC considers the common-law relationship to have ended.

Cohabitation evidence

How do you prove 12 months of living together?

The evidence should show a coherent period of shared residence and a genuine interdependent relationship. Depending on the couple, useful documents can include:

  • leases, rental agreements, property records or letters from landlords;
  • utility, internet, insurance or household accounts showing the same address;
  • government identification, immigration records or official correspondence showing shared residence;
  • joint bank, credit, insurance or beneficiary records;
  • employment, tax or financial records that help establish the same residential address;
  • travel records, photographs, communications and evidence of a shared social life; and
  • clear explanations and supporting records for any temporary period apart.

No single document proves every case. The evidence should support the dates and relationship history stated throughout the application.

Time apart

Can a temporary separation break common-law cohabitation?

Not every short absence breaks the 12-month period. IRCC specifically recognizes that partners may spend short, temporary periods apart for reasons such as work, business travel or family obligations.

The concern is whether the couple actually maintained continuous cohabitation overall. Longer separations, a separate permanent household, contradictory addresses or evidence suggesting the relationship had ended can require closer analysis. If the 12-month timeline is not straightforward, the dates and supporting evidence should be reviewed before filing.

Application route

Common-law partner in Canada class or Family Class?

IRCC has different processing routes depending on the couple's circumstances. The Spouse or Common-Law Partner in Canada class is generally relevant when the common-law partner lives with the sponsor in Canada. Family Class may be used in other circumstances, including when the qualifying partner is outside Canada.

The appropriate route can affect practical issues such as temporary resident status, travel and procedural options. It should be selected based on the actual facts rather than simply where the couple would prefer the application to be processed.

Application process

How a common-law sponsorship application is prepared

  1. Confirm the common-law timeline. Review when qualifying cohabitation began and identify any periods apart.
  2. Review sponsor and applicant eligibility. Check sponsorship restrictions, admissibility and temporary status issues.
  3. Choose the appropriate sponsorship route.
  4. Prepare sponsorship and permanent residence forms. Addresses, employment, travel, family history and relationship dates should be internally consistent.
  5. Build the cohabitation and relationship-evidence package. The evidence should support the claimed 12-month period and the continuing relationship.
  6. Submit the applications and required government fees through the applicable IRCC process.
  7. Complete biometrics, medical examinations and other requirements when requested or applicable.
  8. Respond to IRCC during processing. Additional documents, explanations or an interview may be requested.
Documents

Documents commonly needed for common-law sponsorship

The exact checklist depends on the couple and country-specific requirements, but a file commonly includes:

  • passports and identity documents;
  • civil-status and family documents;
  • proof of the sponsor's Canadian citizenship, permanent residence or other qualifying status;
  • documents establishing at least 12 consecutive months of cohabitation;
  • evidence of shared financial, household and social life;
  • police certificates and medical information when required;
  • documents for accompanying or non-accompanying family members where applicable; and
  • translations and supporting explanations for documents not in English or French or for unusual circumstances.

IRCC document checklists and country-specific instructions should be reviewed for the actual application being filed.

Working in Canada

Can a sponsored common-law partner apply for an open work permit?

Some common-law partners living in Canada who are being sponsored for permanent residence may qualify for an open work permit.

Under current IRCC instructions, the principal permanent residence applicant generally needs to be in a genuine relationship with the sponsor, be included in a permanent residence application with an acknowledgement of receipt (AOR), and be living in Canada with the sponsor. Temporary resident status requirements also apply.

IRCC has a limited exception that may allow an eligible applicant to apply before receiving the AOR when their current work permit, study permit or temporary resident status will expire in 2 weeks or less. A sponsorship application by itself does not authorize a person to work in Canada.

Common issues

Issues that can make a common-law case more complex

  • unclear or incomplete evidence covering the full 12-month cohabitation period;
  • different addresses appearing on official records without an explanation;
  • long periods apart during the claimed qualifying period;
  • a relationship timeline that conflicts across forms and supporting documents;
  • previous marriages, partnerships or sponsorship undertakings;
  • temporary status problems in Canada;
  • criminal, medical or other admissibility concerns; and
  • undeclared family members or inconsistent family-history information.

These issues do not all have the same legal effect. The important step is identifying them before submission and addressing them accurately.

FAQs

Common-law sponsorship FAQs

How long must we live together to qualify as common-law?

For this sponsorship category, IRCC generally requires at least 12 consecutive months of living together in a conjugal relationship, without long periods apart.

Do we need a joint lease?

No single document is universally required to prove the relationship. The application should contain evidence that, taken together, supports the claimed cohabitation period and genuine relationship. The applicable IRCC checklist should be followed.

Can short trips apart be acceptable?

Yes. IRCC states that time apart during the 12-month period may be acceptable when it is short and temporary, such as for family obligations or work travel.

Can I sponsor a common-law partner who is outside Canada?

Potentially, yes. A qualifying common-law partner can be sponsored through Family Class when the applicable requirements are met. The couple still needs to establish the qualifying common-law relationship.

Does having a child together automatically make us common-law for immigration sponsorship?

The family-sponsorship definition still focuses on the required common-law relationship and cohabitation. Parentage alone should not be treated as a substitute for the sponsorship requirements.
