The playoffs basically involve two game series in which the winner is based off aggregate. TFC lost on the road in game one 3-2, and they were leading 3-2 this game, so with a 5-5 aggregate they were forced to go to extras (away goals are worth more, but with identical outcomes they were cancelled out). Now they play two 15 minute halves and determine who the winner is. With TFC scoring two in the first half of extras to make it a 7-5 aggregate lead, Montreal now needs to score two to tie. The away goals rule also does not apply in extras.
