Okay. So for Express entry program. After PR approval, both of us(first partner and I) still have to maintain relationship and living together? Are there rules restricting the break up after PR approval?This is a mess. This also puts into doubt whether the first partner should have been included in your PR application. Looks like you may spent minimal time in Canada with the 1st common law partner (how long?) after landing and then broke up, left Canada and started another common law relationship right away with someone you had been living with as a roommate or potentially more. This is a highly unusual situation. What happened to the first common law partner? Do you have proof of cohabitation in Canada? Did they remain in Canada? As a couple you would have either both relocated to Canada on a permanent basis or both planned on a short landing and leaving together.
How long did you live with the 2nd common law partner before returning to Canada? Longer than 12 months?
Yes, longer than 12 months.
