Monday's Game 6 of the Stanley Cup Final between Vancouver and Boston was CBC's highest-ever rated NHL game.
The game, which saw the Bruins defeat the Canucks 5-2 to tie the series 3-3, averaged an audience of 6.6 million viewers, making it the most-watched NHL broadcast in CBC history.
The introduction of a new measuring system in September 2009 has seen sports TV ratings skyrocket in Canada.
The game peaked at 8.1 million viewers near the end of the first period and reached a total of 16.2 million viewers — the most ever for the final on CBC.
This is the first Stanley Cup final featuring a Canadian team since the Ottawa Senators played the Anaheim Ducks in 2007.
Game 7 of the series goes Wednesday night in Vancouver (CBC, CBCSports.ca, 4:30 p.m. PT/7:30 p.m. ET).
