You are justifiably nervous. Anyone looking at your case is going to give it heightened scrutiny. However, you have some positive factors in your favour:
- you have strong documentary evidence that the relationship is genuine.
- you were married before your refusal (it looks much weaker if you are married AFTER the rejection).
You don't mention if you applied inland or outland, but I'm assuming in your circumstances you would apply inland (since you wouldn't go back to your country for an interview, presumably, since a refugee claim suggests you would suffer irreparable harm by returning). In that case, it would seem you would want to drag out the refugee process as much as possible (since as long as it is still a pending matter, you shouldn't be subject to removal.) The first stage of such application processing takes approximately a year (approval of the sponsor). If they have doubts about the legitimacy of your relationship, they will schedule you for an interview.
Of course, nobody on this forum can tell you definitively if they are going to ask you for an interview. Given the circumstances I'd think it is a distinct possibility, but it's certainly not guaranteed because as you noted you submitted considerable evidence. They may still doubt your sincerity with respect to the marriage, however, even if they think your wife and her family believe it is legitimate - there have been too many suspect cases in which the Canadian spouse thinks the relationship is genuine. On the other hand, with the new five year sponsorship ban (so even if your relationship were to dissolve, you would be banned from sponsoring anyone for five years after you gain PR) and the pending two year relationship test (so that your relationship must last at least two years past the point you gain PR - but this is pending and has not yet been finalized) there is an argument against that perspective in any case.
Sadly, you are stuck waiting. I'd suggest you think about the likelihood of an interview. Begin collecting additional information about your lives together. Go over the interview questions, etc. Be as prepared as possible, so that if you are required to do an interview, you will be ready. The only other thing you can do is wait.
