Chinese citizenship for babies born to foreigners?

You baby can autimaticlly gain Chiense citizenship if she/he is born here, but you have to give up anyother nationality that she/he might get, because China doesn't admit dual citizenship.

I have heard that if your baby is born here it is born Chinese national, and your home country while they can povide you with citizenship will not offer you a birth certificate, which later would make things very complex for documentaiton. In some cases you will have a choice what citizenship you wish to take on, it is unlikely though that you can obtain dual citizenshoip because the last tim eI checked China does not offer thta option, you are either Chinese, or you are not. Personally I would seriously consider the benefits later in life your child will enjoy from having a first world birth certificate - it may make things much better for them.

If I have a kid I intend to fly back to Canada with my future wife to have it

For now though, go have a talk with your embassy about the policy, and don;t rely on a phone call, they can and sometimes do tell you anything over the phone. Good luck,
