From a practical perspective, apparently the Rogers Centre is available on Sunday, but I threw out the Toronto option in jest. But you do know they played 8 games here over the last half decade right? The customs issue isn't really the problem - except maybe how short the lead time is to get any waivers, etc. The reason it won't happen is there is some animosity between the Bills (and their fans) and the whole "Bills in Toronto" series adventure.
