I did some digging. Atlantic Digital Networks appears to be related to Humminah Humminah Animation, a Halifax-based animation company with a second studio in Hamilton.
I'm struggling to understand why they decided to launch a TV channel now. From what I can tell, the vast majority of their productions (if not all) have been service/work-for-hire shows they don't own. The lineup itself isn't really convincing, with a lot of stuff that's either aired on the Corus channels or would've been rejected by them.
