MLS Cup Playoff fever is high in Eastern Canada right now, and Montreal may be the center of the "epidemic" at the moment.

The Montreal Impact announced on Friday the club has sold more than 50,000 tickets for the Audi 2016 MLS Cup Playoffs Eastern Conference Championship first leg match, taking place Nov. 22 against Toronto FC at Olympic Stadium (8 pm ET, TSN1/3, RDS in Canada | ESPN in US).

As a result, the game is setting up to be one of the Top 5 attended Impact matches at Olympic Stadium in history, and that place in the ranking could yet climb, with less than 10,000 tickets left for purchase as of Friday.

To show the progress of ticket sales for the game, the club lit up the stadium tower like a barometer. On Friday, the tower was 83 percent lit.
