I too applied to the U of Calgary in the specialization of Leadership in Human Services. I have been working with my BSW for 11 years and have been in a management position for the last 2 years with a company that I believe could benefit from someone with a learning in LHS. I have been unable to find any information about when decisions are mailed out for this particular specialization but since registration for the 2017 Summer semester begins on February 4th I assume that it will happen before this date. Best of luck to you!
