No she does not have one...can I just use her birth certificate to drive across the boarder?
You can simply enter Canada. Your child will enter Canada as a visitor on their US passport. You will need to submit an application for your child to be recognized as a citizen. Until your child is recognized as a citizen, it's likely your child will not be covered by Canada's provincial health care program. You should buy insurance to cover emergencies. Similarly, as a returning resident, you likely won't qualify for health care coverage for the first three months you are here.
