@ matthew_fitzy :
my boyfriend are in a sort of similar boat. he is australian, I am canadian and we are both living in canada together. He came here on a working holiday visa and has been here a year now and we just sent off our application. we are applying outland through Sydney VO.
when we first started the application, I was unemployed and my bf was working full time. however I got a job 2 months before we applied so I was luckily able to tick the box that said "employed" but from what I have read through this forum and CIC, the sponsor's income does not matter at all as long as the sponsor is not on welfare. It would probably help to include your work info as well as that is what we did. We stated that I was unemployed for a number of months and my boyfriend worked full time supporting us...
maybe if you apply for the working holiday visa before you apply, that way you can send a copy of your visa with the application, proving that you intend to live exclusively in canada, that's what we did.
I think the more info you provide the better, so that they have a real indication of your intentions to be in canada together.
not sure if that helped at all, but nice to hear about someone else in a similar situation
