I have not heard back from U of A's SPH program either. In April and was told admission decision would be sent out April 30 - still no word. Since this was the first time SPH used SOPHAS, I know there was a bit of a delay (SPH waited until all transcripts were verified for applicants who made the January 31 deadline). Perhaps this has sometime to do with it? That said, others have posted acceptance/rejection updates on the grad cafe's admission results page (MPH programs, not MSc).
