if u r sponsoring spouse there's NO INCOME requirement...i do not understand why some ppl here would suggest otherwise

....stay hopeful!!! of course u need to explain how u will support urself: how she's searching for job, how she's in touch with potential employers, how u r searching for job, how u'll get support from her family or friends there (staying with them, help financially) in case u will both need...even show bank account statements, show u have savings to start a new life in Canada, anything is good
sponsoring a spouse is different than sponsoring parents for example because most of the parents have very low chance of getting back in the job market, hence there's a strict income requirement for the sponsor...but the spouse will not just stay home waiting for the wife/husband to support them....they will both try to find job, have their own income, etc..it's a different situation
there r plenty of cases where the sponsor had no job and got approved...hopefully it will b ur case too
as for the medical, again there's no strict requirements regarding it...i'm not even sure why she would say she had a medical condition: she is the sponsor, no one should ask her that...i didn't see questions like that in the sponsor forms; only the applicant has to pass medical exam
also Canada does not treat men sponsors and women sponsors differently no matter where the visa office is...if the process is slow is cuz there r a lot of ppl applying, they lack in staff and some applications could have longer security/background checks...
good luck!
