Sorry I'm in North Carolina this week, the Horseshoe falls are a day trip, they are about 2 hours away so if I were you I'd do those on the weekend. As to a pub I'd say it all depends on where in Toronto you are but thje best thing to do I'd think is to do a google search for a pub within walking distance from your hotel. Perhaps a trip to the CN Tower would be an idea, or the ROM which has the Ten Commandments and the dead sea scrolls on display.
