due South was initially produced by CBS in conjunction with CTV, but CBS pulled out in the first year, leaving CTV scrambling to finish off on the show, which was canceled at the end of the second season. A year later, CTV was able to obtain enough international funding to bring about a spin-off, also titled due South. In the United States, the spin-off and the original series were treated as four seasons of one series as featured in this guide.
