Common-law partner in Canada: requirements and proof

For Canadian immigration, a common-law partner is someone you've lived with in a conjugal relationship for at least 12 months in a row, without being married to each other. The rule applies to sponsorship, Express Entry, work permits and most other applications.

What "12 consecutive months" means

  • You've lived together continuously for at least a full year.
  • Short, temporary separations (for work travel or family obligations, for example) don't break the 12 months.
  • Living together part of the time, or only on weekends, usually isn't enough.

Documents that prove you live together

Send as many of these as you can, covering the whole 12 months:

  • a joint lease or mortgage, or property in both names
  • utility bills, phone or internet bills at the same address
  • joint bank accounts or credit cards
  • government ID and tax returns showing the same address
  • insurance naming each other as beneficiaries
  • mail sent to both of you at the same address
  • photos together over time

Most applications also need IRCC's Statutory Declaration of Common-law Union (IMM 5409), signed by both of you.

Common-law vs conjugal partner

Relationship length12+ months living together12+ months in a genuine relationship
Living togetherRequiredNot possible for reasons outside your control
When it's usedMost applicationsOnly for some sponsorships, where you couldn't marry or live together

Conjugal sponsorship is for couples who can't live together or marry, for example because of immigration barriers or legal restrictions in the partner's country. It needs strong evidence.

Common mistakes

  1. Applying before the 12 months are complete.
  2. Gaps in the paper trail, such as a lease in one name only, with no other proof.
  3. Separate addresses on ID or tax returns during the 12 months, without an explanation.
  4. Calling yourselves common-law in one application and single in another.
