There is no "basic" requirement for spouses. I have only heard of one case where a couple was refused because of lack of income and in that case, the husbands reported income was only $5000 a year (he may have been working under the table) and because his wife spoke almost no English, they did not think it likely that she would be getting a job soon after arriving in Canada.
Even students and housewives have been accepted as sponsors. Immigration just wants to know that you will not end up on welfare. If you show that you have at least some income and you have a habit of working as opposed to a habit of being unemployed, you should be fine.
