My LTATT from Silverdale took exactly 12 days...did the club ATT course and the mandated 4 prob shoots in just under 2 weeks and it was waiting for me after my last shoot. Issue date on the LTATT showed it was 12 days from the day of my course. That was some time ago though so not sure how much has changed.
Think it has more to do with the CFO and the time of year than anything...I hear there is one person in the a ontario CFO office that does ATT's...
