Is Canada on a different time then the East Coast in the States ? If not expect it around 11:30. I remember in 07/08 having many big HBO PPV fights set to tape at 9 so I can catch the undercard. Id always get off work at 11 and by the time I pulled up at my house id be getting in the door around 11:25/35 ish and the fights usually would be getting ready to start. When I got home for Mayweather/Hatton, Pavlik/Taylor II, Jones/Trinidad the last undercard bout was still on when I got in. When I ordered Mosley/Cotto it was the 3rd round when I got in the house but there was 2 KOs in the 1st round on the undercard which speeded things up. Probablly to much info there but I hope I could help give you an idea of when the big fight should be starting. Add in another 15 minutes for the brief promo, intros, walkthrus and maybe a national anthem.
