If it's tied, tiebreaker game for the division. (either NY or Toronto, depending how it ends) And as it stands right now, winner goes to the ALDS, the other plays the wild card game against Texas, LA or Minnesota.
Here's the official jargon by MLB:
"If one game is needed to break a tie for a playoff berth between two teams, it will be played on the Monday after the scheduled end to the regular season, hosted by the team that won the season series against the other. That applies to determining a division championship whether or not the losing team would still qualify as a Wild Card."
Basically, tiebreak's at the Rogers Centre as it stands, as the Jays have an 8-4 advantage in the tiebreak.
