Saw you want to watch South Park on KSTW CW via Cable and it got replaced by an Canadian Feed that always happened to the NFL Superbowl with Global and ABC, CBS & FOX. If you live near the Canada/US Border in Canada. just try the antenna trick. I tried using a MANT902 antenna with Radioshack Pre-Amp on Cedar & Oakney Road and got in 5 US Stations from Seattle, WA even if the signal was in bad quality. some people in Canada like Vancouver, Victoria, Toronto & Winstor use Antennas to get HD US Signals to avoid SimSub on Cable TV. I tried to get HD Stations in Nanaimo but i can''t because in not in a good spot for that but some people near the border can using good luck.

How to do it, You will Need

A Big VHF/UHF Antenna like Channel Master and WineGuad and Mount it up HIGH like in the Roof or at the side of a wooden fence

A Antenna Pre-Amp (Low Noise Type)

Point the Antenna to the Station Location (Bust Luck is a clear view of the water)

Make sure you find a Strong spot to Get the Station from Fair to Clear

If you have a longer mast, Big Outdoor Antenna, Antenna Preamp and a good Location to point the Antenna, You are in Luck.

Remember keep Antennas, TV Wire and Mast away from Active Powerlines. Always use caution. and read the manual before you try it.
