Just out of curiosity, no particular reason, as indeed almost all of CTV Two programs (except news perhaps) are simsubs.
When I was in Montreal with Bell Fibe, I got CTV Two Atlantic. It acts as overflow relief for CTV Atlantic. Thus, when CTV Atlantic has programming conflict some of its programs are moved to CTV Two. Being in Atlantic time, those programs sometimes air earlier than the original US-Eastern Time broadcast.
Speaking of which, I do not understand the benefits of having timeshift East, as Central Time sync its TV programming with Eastern Time. As such, primetime in CT starts at 19:00, instead of 20:00. The exception is if one wants to watch Toronto / Montreal local news.
