That depends on your original eAPR. Have you received a PNP from Alberta? If answer is yes, then you must complete your PR landing process in Calagry.
That can be done easily by booking a one-stop flight from home to Calagry. Air Canada or other airlines have code-share agreement with canadian carriers so you can land first at Toronto or Montrael or any other airport and board another flight to Calagry. Then only then you can do the PR process.
This is very common among many whom have received PNP and need to land at the assigned province
Goodluck
