Executive producer Dean Devlin tweeted (https://twitter.com/Dean_Devlin/status/971902483437006848) news of the cancelation: "I will immediately begin the process of trying to move the show elsewhere. Please keep your fingers crossed for us!"

No...

I wonder if it’s because of Noah’s new show.

Really enjoyed the first 3 "Librarian" made for TV movies with Noah Wylie. But the series never really caught on, poor casting and writing being the main problems.
