Hi Malinka,
I'm Canadian and my wife is Russian, just this week we were informed that our application has been sent to Poland for further processing. I sent our application to Mississauga January30, 2014, I was approved as sponsor February 27, 2014, and my wife's application for PR was sent to Moscow. The we waited in silence.
August 29, 2014 (Kemerovo time) is when she was sent an email about the application going to Poland. It doesn't say anything about the wait we can now expect, I'm going by the average of 8 months that CIC shows, and it says to wait for the Embassy to request any documents before sending anything to them. Her medical was done in November 2013 and she's worried she'll have to redo that, but that's up to immigration now.
We're 6 months and waiting, even if Poland takes 8 months it will be quicker than Moscow would/could have been.
Hope this helps.
Peter
