To everyone still waiting: If you are still in the process after 5-6 months the chances are highly unlikely that there are any problems with your application! If you submitted a good application at the beginning, your case isn't complicated, if you have given them the extra documents they requested and are a genuine candidate who qualifies, then the system will work for you. Canada has a quota of immigrants they must take every year by law through this system, and they want us to get through the system and not fall through the system. Just hang on that little bit more and you'll get your PR.
