They are issued with the BOWP (at least in my case)

This is what it says on an official document:

"Document to travel to Canada or re-enter
A study or work permit is not a travel document. To allow you to travel to or re-enter Canada
by air only, we have issued you an Electronic Travel Authorization (eTA) when we issued your
permit extension."

Interesting. They generally aren't issued with "within Canada" apps.

As it was not issued, you can just apply separately.
