Sportsnet is once again going to be broadcasting curling. On the front page of the January 2012 issue of the Curling News their was an article titled "Media Monsters". The article went on to say Sportnet will televise live the early rounds of The National (Jan. 25th - 29th) and The GP Car and Home Players' Championship (Apr. 17th - 22nd).
Someone I follow on Twitter posted an image from that article.
