I think you will find the the exec producers of Dark Matter did not CREATE the Stargate shows, they merely came on board in the 4th season of SG-1 and helped run things from then on out for the rest of the series. (and had a hand in Atlantis and Universe as well)

And as nepotism goes, it appears that many staff and cast from the SG shows are working on this as well, but that is Vancouver Scifi for you.

You, my Dear Sir, are a treasure.

I don't think nepotism means what you think it does.

@3 "nepotism: the practice among those with power or influence of favoring relatives or friends, especially by giving them jobs."

Standard fare in tv and film productions. Part of why I couldn't get into the business since it was so often who you knew and not what you could do.
