If one lives far enough north you have (thankfully, I do) two CTV channels (CTV and CTV2) which cover the NFL. All the Sunday night games until yesterday were on CTV2. The CBC will have marathon Olympics coverage in a couple of weeks, running pretty much around the clock save for "The National" and local news. CTV, Global and Citytv carry many of the shows from the U.S. Networks, largely in the same timeslot as the originating U.S. network. So, until Tegna and dish make nice you may have an option there.
BTW: CTV in Canada will have the "Big Game." Yes, THAT one.
