This all boils down to whether she explicitly renounced her US citizenship (to a US government official) or had it explicitly revoked, vs. assuming her US citizenship was lost as a result of taking Canadian citizenship.
If there was explicit revocation or renunciation, her citizenship is gone and she would have to go through the usual N-400 process to get it again. But if it was just an assumed thing, she most likely still is a US citizen and should be able to obtain a US passport.
