Yes I know but was trying to give some encouragement too. That and I am too happy to shutup now since up til last night I had been preparing to book MY trip to Russia instead.
The thing they will worry about the most is will she leave Canada. A single woman from Russia visiting a guy in Canada will be a risk to stay in their eyes. They will look at your plans and if they are well thought out, or just "a visit", they will look at her ties at home, family, home, jobs, and even how well paid she is.
It's a hard thing to try to prove something that is in the future but I think that is the most important part of what they look at.
