My feedback: it does not matter what people here on this board say or think about whether it was an emergency, necessary, or whatever.
Or phrased as Jeff 'the Dude' Lebowski would: "that's just, like, their opinion, man."
They don't know and some profess far more certainty about these things than seems reasonable.
It only matters what the CBSA or IRCC officer evaluating your reasons thinks (and if it comes to that, the "Minister's delegate" - another govt officer - and/or IRB or the courts later on).
I don't mean to encourage or discourage you with respect to your chances (I don't know what they are); just take what people say as testing your argument and how you might respond (if asked or if it comes to that).
The CBSA/IRCC officers MUST consider your reasons. They don't have to agree with them or give them a lot of weight, but they have to consider them. Make the best case you can.
Dear I did right or wrong, I don't know. On that time I moved to Canada only 20 days. It was very hard times for me. I could not find house to stay, no job and etc. I could not deal with health card, and it expired. I choose to save my vision. On that time I had 2 years 6 month and earlier I stayed in Canada 5 months. it was enough time for me to save PR. Unfortunately, the things happened, I returned to home country and next day doctors made surgery on my eye. Besides I am nearing to 40 years old, the gel in my eye continued to separate. If someone has myopia and he got surgery for detachment he should be in regular checkup on doctor. My doctor started to do regular checkup on my eyes. after that they prohibited me to fly because it was risky.
My family felt very depressed. Me, my son is already 4 years in control of the Psychologist because we could not move to Canada permanently(my mother health problem, she passed of in the end, my father in law health problem? he also passed off and etc) . My son has very bad insulin problem and he wants to live in Canada. All of happening affect his health. I have got letter from doctor, we have laboratory analysts, also my son teacher gave letter about his depression at the lessons because of Canada. I will try to use this facts as "Best interest of child".
Besides I also have letter from Psychologist mentioned that, I was very depressed, because I could not move to Canada. I have receipts about medicine İ bought, payments and etc. Honestly to say İ tried Suicide several times, because all problem started after İ got PR and it affected my plans to move to Canada.
Already 4 years my family in the bad situation. I don't know will IRCC or CBSA consider this facts, but it is true that, we tried to return to Canada every time.
Thanks for your all for your suggestion. If you have any other recommendation, how may I use this facts as H&C, please share with me.
