Did she come to Canada on a visit and overstay?
This is a very difficult situation and, unfortunately you may not succeed in being able to bring your mother over on a super visa. Because she overstayed Canada immigration believes that she may do so again and she may not enter Canada if there's any doubt about her leaving after her visit over.
The only way you can possibly succeed is by showing new evidence that will support her clear need to return home. So if she had other family at home that would be one idea If she had a job at home that would also be another. But if she cannot prove that she absolutely will leave at the end of her visit she is not going to be a visa because she is already essentially committed an offence once already.
It is likely best that you consult with an immigration lawyer face-to-face and retain this lawyer to assist you. The lawyer will be able to put your case for it in the best possible light.
