I believe you did so much effort. MP would help and I recommend that you request the GCMS notes. You may get it in less than a month, hopefully. A friend of mine, who applied for study permit, found in the GCMS that the officer confirmed that university tuition fees were not paid but my friend provided the payment receipt. Moreover, my friend got a job offer from the current employer with a promotion and salary raise after getting the degree, in fact the employer partially fund the studies in Canada, but the officer confirmed that the employer does not offer a promotion. My friend realized that the officer do not see all documents intentionally or unintentionally. I hope this is not the case for you.
I discussed your case with a friend. I got some suggestions for you. You may consider adding the following documents to your application or your coming application.
- Wills listing each other as the beneficiary
- Medical instructions granting decision-making power to the other person (such as a living will)
- If your job provides additional benefits, then the other person listed as your spouse/partner and covered under your benefits plan
- Emergency contact or family contact information at your job
From an immigration consultant,
- Did you submit statements of a joint bank account?
- Did you submit any joint utility bills?
