We're also applying through Sydney for my common law visa. Sent it end of September and just yesterday we just received my Selection Certificate from Immigration Quebec.
I'm actually already in Canada with my partner, at her mother's house in Quebec, on a working holiday visa... juuust scraped in as I recently turned 31!
So I guess it's now turn for Sydney to look at my med results and criminal record check, then our evidence of relationship. If I wasn't immigrating to Quebec the processing time would've been so much less, but you get that!
Not too worried about our application being denied as we already got my partner an Australian defacto visa back in 2007 and I can't see why it should be any different.
Good luck everyone!
