I have the same problem than you... my letter of admission is "conditional" to get my master course in my country and also the CAQ from Quebec, the study permit and the medical insurance.
So, even if I demonstrate that I finished my master course my letter will be conditional to get the other requirements.
However, in my opinion, I think that they accept conditional letters but it depends, for example, our academic conditions are not accepted... if we have another conditions like language or some other things, it is possible to apply.
I will wait to get a document which I can prove that I finished my master grade in my country, then I will ask to the registration office to get another letter where the "academic condition" can be removed.
