This is totally uncalled for!!
Between Interest to Sponsor and application, my spouse passed away (would have been co-sponser) which I was not expecting. With out knowing the personal situation dont conclude. If anyone, I need the support of my parents in Canada as I am a mother with a toddler in a foreign country and no extended family!!
I am so sorry!! I can certainly imagine the pain, scare and t he lost feel..
Last year I had heart attack and I keep thinking if I hadn't gone to the emergency, what would have happened to my wife.
My deepest condolences.
If you meet income requirements with your own income, then you don't need to worry. You can just write an explanation letter describing your situation and I am sure IRCC will accept the difference in EOI and actual application.
If you don't meet, the best option you might have is Super Visa for now. I understand the insurance is an extra burden to you. But still, at present, that's your best choice. Sorry once again.
