My current wife is the childs natural mother. What are some issues that could arise from this? Couldn't she get a visa to come canada?
Expect a lot of problems.
1. If you were separated on the day you landed in Canada, you should have told the border agent this. He/she would then have rescinded your PR visa. Of course, who would admit this, but still, just because your papers were finalized, does not mean you were eligible to enter Canada on a PR visa: if your circumstances change, then you are supposed to tell CIC or the border agent, and deciding to separate is a changed circumstance.
2. If you weren't separated on the day you landed, but did separate shortly after, fine, except you have admitted to the government that you were separated before landing in your divorce papers. Therefore when the visa officer processes your application to sponsor your current wife, he/she will be suspicious. They will think the first marriage was a MOC for sure; that means the second application will be gone over with a fine-tooth comb.
3. If they think the marriage with a Canadian was a MOC, then they may also suspect that your relationship with your child's mother was ongoing during the marriage. If that happens, you may not be able to sponsor her.
4. Your best bet is to get proof that the relationship with your current wife was over when you got married to the Canadian; that the marriage to the Canadian was genuine; that you broke up after you landed; and that after breaking up with your first wife you reconnected with your child's mother, fell in love, and married her.
