CBC is yanking Being Erica out of Monday nights, and not a moment too soon. The five-week-old fantasy/drama drew a respectable 644,000 Monday at 9, with 285,000 of those viewers being in the 25-54-year-old demo. That’s up against some stiff competition, including Two and a Half Men on CTV (1,800,000/1,078,000) and 24 on Global (1,259,000/634,000).
