No, that's not the case. Anti-discrimination rules don't allow that.Does country of Nationality works in the speed of application being processed?
May be an application from India or Iran takes longer than an application of Germany or British national?
Any thoughts?
I assume, however, that there is a "secondary privilege" effect: Generally countries like Germany have a bureaucracy that is more compatible with that of Canada. For example, in Germany you don't have the issue of having an actual birthday but also an "official birthday" which is on a different day (something that seems to be the case in other countries). And obtaining a police certificate is very easy compared to other countries (One letter and two weeks). So it is often easier to handle applications from such countries. The same holds true for many other documents.
So that's what I mean with "secondary privilege": Your application will not be processed faster or slower based on your origin, but depending on your origin you might have it easier to obtain necessary documentation which then makes your application easier to handle.
