Yes, that can be an issue. You are saying you are getting roughly $3000 a month, and just to make sure, the papers you sent showed even less than that? That would be roughly $36k yearly. LICO (low income cut off) for 4 people in Canada (except Quebec) is $46,362 yearly. You are 10k short, so it is a problem. If you didn't provide any more evidence to show that you would be able to support your husband financially when he arrives in Canada, or that at least he would not have the need to go into welfare (showing savings or a plan for it), I would say that it is likely that you will not get sponsor approval. The very few cases I have seen that people take many months to hear anything about sponsor approval it is because they are refused as sponsors. I am not the most experienced member in the forum, but I believe that your income is an issue to sponsor your husband indeed. You would have needed to show a detailed plan, or explanations, and some evidence, that the four of you would be doing okay in Canada, financially speaking. If you are sponsoring your husband + your step daughter, then your family size would be 5, and in that case LICO would be $52,583, for 2018. For that one, you would be $16k off.
