The Toronto Maple Leafs have always had one of the priciest, hardest to find tickets* anywhere in the league. It was a testament to just how popular this team has been despite over a half century of not even losing a Stanley Cup Final.
*Not counting resellers
However, it seems as of late only the former is true. While tickets are still extremely expensive - face value of a standing room only ticket is $131 - they don’t seem to be hard to find as of late. I get numerous emails about available tickets multiple times leading up to game days, and at least once on the day of the game.
