There's also a much bigger complicating factor here, and that is the OP herself, is a current refugee claimant from Palestine. She also has a brother who is currently trying to do the same thing, and has a friend who is also doing the same thing in the US, seems like everyone is trying to become a refugee claimant here.
Although the friend isn't a big deal, I think the brother and sister refugee claims might have a significant impact on the spousal application. I have a feeling that this sister is possibly trying to flee her home country by marrying a Canadian (hence the fact they've never met and planning to marry after very short courtship). I think eventually CIC will find out that this sister already has 2 siblings attempting refugee claims, and with this short courtship and never having met, this spousal application is doomed to fail.
