TL;DR: Hopefully soon.
The FAQ document posted on the Schulich “Admission & Requirements” page states the following: “We have rolling admissions, with offers being made as early as November and continuing to May. In May, we review all outstanding applications to be considered for a possible interview. If you are selected for an interview, we will contact you by the end of May to set one up. Interviews take place in Vancouver, Calgary, Toronto, and Halifax.”
That being said, another paragraph on the same webpage also states: “The Admissions Committee may consider applications as soon as they are received or it may postpone consideration of some or all applications until June.”
It’s not clear which is the most up-to-date information. That FAQ was technically for the Class of 2019, but hasn’t been updated since - and its continued presence suggests it may still be generally accurate. The webpage, meanwhile, has no date associated with it, so it’s unclear whether the June date is newer or older. Of course, it’s also possible that the May/June date was only a rough guideline in the first place. Either way, hopefully you’ll hear back soon. Best of luck!
