What is proof of common-law partner in Canada?

To prove a common-law partnership for Canadian immigration, you must show IRCC that you and your partner lived together in a committed, marriage-like relationship for at least 12 continuous months, allowing for short, temporary interruptions. Since common-law unions are not formalized through a marriage certificate, IRCC relies heavily on solid documentation that demonstrates cohabitation and a shared life. If you need help understanding what documents are best to include, our Canadian immigration consultants can guide you through the process. You can also review a complete program overview on the Spousal Sponsorship page.

The most important evidence is clear proof of living at the same address. This can include joint leases or mortgage agreements, rent receipts with both names, property ownership records, or official mail addressed to each partner at the same residence during the required 12-month cohabitation period. These documents help IRCC confirm that the couple genuinely lived together. For more information on relationship evidence, including examples, practical tips, and common pitfalls, refer to our proof of relationship page.

IRCC also looks for evidence that your lives are financially and socially integrated. Useful documents include:

• Joint bank accounts or credit cards
• Shared utility bills (electricity, internet, phone, etc.)
• Joint insurance policies (home, life, health)
• Records of shared expenses or household purchases
• Beneficiary designations naming each other

To further demonstrate the relationship’s genuineness, couples may include supporting evidence such as:

• Photos together
• Travel history
• Communication logs (if applicable)
• Letters or sworn declarations from friends and family
• A signed Statutory Declaration of Common-Law Union (IMM 5409)

IRCC reviews the overall picture, not just one document. Strong applications typically include a combination of cohabitation proof, financial integration, and evidence of an ongoing, committed relationship. When properly documented, a common-law partnership is recognized the same way as a marriage for Canadian immigration purposes.To understand the expected timeline for these applications, you can also review our related FAQ: “How long does it take to sponsor a common-law partner in Canada?”
