I am not sure , it could be since ratings are pretty low.
it has been on the edge each season of being canceled,
but it is fairly cheap and they like it so may get a 5th.
It is good if you like historical period shows.
The guy that plays abe bothered me, I dont care for the actor and on top of that
his part was not smartly written.
The other characters are all likable and often steal the show, like robert rodgers, and simcoe.
