Schao113, since you have submitted a common law application, you need to provide evidence that you and your partner have lived together CONTINUOUSLY from FEBRUARY 2019 to FEBRUARY 2020 (the date your application was received). This is the one year period that IRCC cares about.
You can go ahead and provide evidence prior to feb 2019 but anything you provide is really just a bonus. What you really need is strong evidence of continuous cohabitation from Feb 2019 to feb 2020. If your application was received Feb 3rd, 2020, you need evidence that proves continuous, uninterrupted cohabitation from feb 3rd, 2019 to feb 3rd, 2020. Hope this helps.
Hi there, I submitted proof of joint insurance and other documents from months in between Feb 2019-Feb 2020 in my initial application, which wasn't enough. I am focusing around the Feb 2019 time frame now as that was the one year mark that we have less evidence for. I will resubmit some documents such as a medical bill in March 2019. Any advice on how else I can show CONTINUOUS cohabitation given our limitations? We unfortunately just didn't have to get things like joint insurance until Nov 2019 which I've already provided the IRCC. We will get whatever we can that covers a wide range of time and all our letters will state we have been cohabitating consecutively since Oct 2018. Thank you!
