Make a month-by-month address chart for the full cohabitation period. Record when you began living together, any temporary absences, address changes, and the documents available for each period. A short temporary absence does not necessarily end cohabitation, but explain its dates and reason and check IRCC’s definition.
Use a range of genuine records where available: a joint lease or rental agreement, shared utilities, government or financial mail showing the same address, insurance or benefit records, and documents about shared household responsibilities. If only one partner is named on a lease or bill, do not alter it. Add other records and a short explanation of the living arrangement. The goal is to show how the evidence fits together, not to produce the largest possible pile of paper.
The application also asks about the relationship itself. Select evidence that makes the history understandable, such as shared financial responsibilities, travel, communication, family and community recognition, or significant events together. Use dates and captions for photos or message excerpts, and avoid overwhelming the officer with repeated screenshots that do not add new information.
Check the current country-specific checklist and translation rules. If a document is missing, explain why and consider whether another reliable record supports the same fact. Do not create a retroactive lease or ask someone to misstate an address.
For a Brampton couple who moved during the year, explain each address transition and keep supporting records from both homes. Consistency among the application forms, lease dates, work history, and travel records is often more useful than a generic statement that the couple has lived together.
