You mentioned about the savings and the joint accounts and the individual accounts and your boyfriends mother having your back in the letter. But like I said you probably did not give them figures. They need those numbers cause that gives them a way to calculate. And to validate your numbers you will definitely need to give then the bank statements that show those numbers.
How much you have earned so far and are still earning will also clearly show on your notice of assessment from cra. Include that too.
If you are worried about sending financial details to ircc, don’t be. Trust me, I have done it, and it is literally what they need to see! They need those numbers.
And alao throw in the proof of addressof your current residency. You need to show them that your bf’s mother has two houses and YOU BOTH are living in one of them. That will show that you are living with her. And she then has to explicitly mention on her letter of explanation (yes she will have to write another detailed one) she will have to say that she is letting you live there till you can get back on your feet after uni. Cause a statement in a letter from you stating that “you will get a full time job after uni” is not enough for ircc. Cause they need to make sure that if your plan does not turn out successful (which sometimes it doesn’t, cause full time jobs, jobs in general are scarce now) that you have someone or something to fall back on.
Like I said, cause your situation is a little different where your bf’s mother is supporting you both. You have to, have to, have to include numbers and statements! Everything you state on that letter needs a proof.
Savings? - prove it
Rent free? - prove it
Living in a free house with mother? - prove it
Joint account with money to use? Prove it
All I am trying to say it, if you have already made these statements in letters before and ircc still is not convinced, you now need to prove it all by statements, affidavits, leases, property paperwork (for the second house where you live for free).
Its is a tedious process but trust me if done correctly will not take you more than three days! And if you need help or a template I am more than happy to share things I made during my student visa and mh parents visitors visa. PM me and I will reply as soon as I can
Breathe.
you will be fine. Just need to sort out tge paperwork
