In order to apply for a super visa, you will need to meet minimum income requirements and this income will have to come from Canadian sources. In other words, to apply for a super visa, you will need to have a job in Canada that meets the low income cut off. A super visa will allow your mother to visit Canada for a prolonged period of time - but technically not live in Canada.
Alternatively your mother can apply for a regular visitor visa. There is no income requirement on your part for a regular visitor visa. A visitor visa will allow your mother to visit you in Canada for a few months (but once again, will not allow your mother to live with you in Canada).
There is nothing stopping you from applying to sponsor your spouse and also having your mother apply for a visitor visa (either super or regular) at the same time. A visitor visa will be processed faster than permanent residency sponsorship.
