If that was the case, then you are fine, all I sated was that if your were in a CL relationship, then the same should have been disclosed irrespective of whether your partner is accompanying or not. If you were not in a CL relationship, then you need not have mentioned it.
As per IRCC:
A common-law relationship is legally a de facto relationship, meaning that it must be established in each individual case, based on the facts. This is in contrast to a marriage, which is legally a de jure relationship, meaning that it has been established in law.
In the case of a common-law partner, documentary evidence should include:
- a completed Relationship Information and Sponsorship Evaluation questionnaire (IMM 5532) (included in the application package)
- proof of separation from a former spouse if either the sponsor or the applicant were previously married
- a completed Statutory Declaration of Severance of Common-law Union form (IMM 5519) if either the sponsor or the applicant were previously in a common-law relationship with someone else
- if the principal applicant and sponsor have children in common, long-form birth certificates or adoption records listing the names of both parents
- photos of the sponsor and principal applicant showing they are in a conjugal relationship
- at least two of the following sets of documents. If the sponsor and principal applicant are unable to provide documents from a minimum of two of the following sets of documents, a detailed written explanation must be provided:
- important documents for the principal applicant and sponsor showing they are recognized as each other’s common-law partner (such as employment or insurance benefits)
- documentary evidence of financial support between the principal applicant and sponsor, and/or shared expenses
- other proof that the relationship is recognized by friends and/or family (e.g. letters from friends/family, social medical information showing a public relationship)
