Alberta does not automatically accept either ASME code cases or Interpretations. See Alberta document AB-516 Rev 11 2016-01-08 page 25:

Interpretations and code cases are not part of the code, and are not automatically adopted for use in Alberta. Use of interpretations and code cases may be accepted on an individual basis upon application to ABSA. Check with ABSA Design Survey before attempting to apply interpretations or code cases.

For example code case 2596/cold stretched vessels is accepted for limited use in Alberta  see Bulletin IB13-008

Interpretations for all ASME code can be found at
