I asked my department today (Master's) and they said they haven't heard anything yet and that although they are told to wait for students to get their letters, he will let me know when he hears anything. I'm in Ottawa. My personal assumption is that they started work on the Master's letters after they finished with the PhD's, but since there are many more Master's applications, it won't just take until this Friday but they will be finish them sometime mid next week.
We should start a petition asking them to set a strict deadline. Even if it is May 30th of every year, at least they would not be causing us (and themselves by having to answer our emails) such headaches. Anybody up to writing something up?
