How will Canadian stocks react if the BOC cuts rates by 0.5%?

I've read that it's looking like the BOC will do a bigger cut of 0.5% on Wednesday. Will this positively or negatively impact Canadian companies? How should I be thinking about this cut?
I'm not looking to do anything risky or foolish, I'm just curious and want to learn how our bank rates impact Canadian companies/market or if it's just a crap shoot $Royal Bank of Canada (RY.CA)$ $The Toronto-Dominion Bank (TD.CA)$ $Bank of Montreal (BMO.CA)$
