CBC is gearing up for the latest installment of its interactive national quiz fest, Test the Nation: Sports, which hits the air at 8 p.m. on Sunday. The two-hour event is hosted by Wendy Mesley, who will be joined by Hockey Night in Canada‘s Ron MacLean. Don Cherry will also make a guest appearance, delivering one of the 50 questions from Coach’s Corner.

The pubcaster and its partners are again inviting participation from viewers online, by mobile or in public. Viewers can download the official scorecard at www.cbc.ca/testthenation and will have the chance to win a Wii by texting ‘play’ on their cell phones following an on-air call to action.

Test the Nation: Sports will see 240 Canadians from every province and territory flex their brains. It pits six teams or sports personalities against each other while celebrity ‘coaches’ play from the sidelines — including Alan Thicke (jPod), designer and Project Runway mentor Brian Bailey, hockey legend Paul Coffey, stand-up comedian Debra DiGiovanni, musician Chris Murphy from Sloan and actress Victoria Pratt.

The CBC’s first Test the Nation broadcast in March 2007 raked in 1.5 million viewers, and it was the most successful so far. Last September, Test the Nation: Watch Your Language attracted about 900,000 viewers. Following this month’s Sports edition, Test the Nation: Canada, eh? will air on CBC’s fall schedule.
