To answer a question from a ways back, CTV Saskatchewan has always run Wheel and Jeopardy at 5pm, even during the winter when they air at 6 on WDIV. (They wouldn't bump the 6 o'clock news to simsub these shows -- the newscast is still more lucrative.)
I haven't seen the fall program grid for either network, but I'd have to assume that in this market, CBC will leave the two shows at 5 and 5:30, as a lead-in for CBC News at Six, and hope for some kind of bump.
I don't think up until now they've made much of a difference in that respect, though -- people are pretty entrenched in their news-viewing ways in this market, and I don't think Global (then STV) got much of a bump for their nascent news operation when they had the rights to Wheel and J! in the late 80s and early 90s, and CTV news was so powerful then, that it wouldn't have made much difference when the shows switched over to CTV.
