Excerpt from Toronto Star article:

The six Canadian teams account for 31 per cent of the $1.1 billion (U.S.) in league ticket revenue, and have gone through league-leading double-digit increases over last season, according to the internal NHL report.

Overall, the league has seen its ticket revenue rise almost 10 per cent, but 11 of the 24 U.S.-based clubs were either revenue-flat or lost ticket income.

Atop the list of income winners is the Maple Leafs, who nudged out the Montreal Canadiens to lead the league this past season with $1.9 million worth of ticket revenue per game. Based on 41 home games, that’s $77.9 million a year – not counting revenue from pre-season games. A year ago, the Leafs generated $1.5 million a game, according the report obtained by the Star from several league sources.
