The Slump-O-Meter is a virtual stack of hockey pucks (regulation size one-inch thick), that grows inch-by-inch, puck-by-puck, one for each day since the Leafs last won the Stanley Cup on May 2, 1967. The Slump-O-Meter stack will continue to grow puck-by-puck until the drought ends.

As of today, the Slump-O-Meter pucks stack is 1,737 feet high, which is almost the height of the CN Tower (1,815 feet and 5 inches). The Slump-O-Meter will be as tall as the CN Tower on December 22, 2026 if the Leafs drought continues until then.
