I think the income doesn’t matter. We don’t know for sure as it’s always a different person handling our cases.
But, for all we know it may be a hidden criteria when they are processing your application.
Net worth is an important issue here, that’s why they have a requirement on proof of funds, how much an applicant has to have in cash per person for the application. They don’t want you struggle over there if they decide to give you the PR. This also means that the money side of things is very important in an application.
I have read other forums about how some families struggle over there after their move because of lack of money and the difficulty of getting work there, despite having the minimum amount needed while they got their visas.
I believe the visa officer has to be also convinced that you can make a living on your current skills over there. If not, they would probably deny you on eligibility. Remember, they are expecting people in this category to be self-employed over in Canada, so if at any one stage you’d mention that you’d find a job there or do something unrelated, they’d probably fail your application right away on eligibility grounds.
If they can have such a requirement, it may also be possible that they may be seeing how much you are making in your current self employed situation. It may pose as a big risk to your application under the eligibility part? I’m just guessing. Would you give green lights to an applicant that makes $100-200 a month on self employed? Very hard to make a case here if I was the visa officer. Then again I could be wrong.
Remember to prove that you are paying taxes annually that will also prove how much you earn in a year. I don’t see how they will grant cases to an applicant who doesn’t pay taxes as that is one big proof on the applicant’s application on amount derived from self-employment.
Still, no harm to try man, you will only find out when you submit your application, so all the best!
