The relationship between Iran and Canada is getting worse and worse since last week. I don't want to be optimistic... the thing is it's actually true. Just like the way Canada banned Investment Class for Iranians, they might suddenly do the same thing to other classes. Canada is now very concerned towards fraud application & documentation around Persian Gulf states and is cautious about the processing of Iranian applications received by their embassy in Ankara.
This is not personal opinion, I just summarized what I have read on valid and reliable news. But I truly hope the situation wouldn't have any influence on our files.
Always wish for the bests.
