What Canadian is drawing big social media crowds?

Help me out, if you can with this:

Actor Rainn Wilson, who is wonderful as Dwight on The Office, has more than 1.2 million people following him on Twitter. Oprah has 2 million. Late night talk show host has 2 million tweeps.

That's the U.S.

What about Canada?

How are Canadians or Canadian institutions doing when it comes to drawing big crowds on Twitter, Facebook or other social media platforms? I don't think we've really hit that mass inflection point yet. Comedian Rick Mercer, for example, has only about 7,000 tweeps or followers and a little better than half that when it comes to Facebook friends. David Suzuki has something north of 10,000 tweeps. But do we have anyone in this country cracking 100,000? How about 50,000?

To put things in perspective: The national network newscasts I've worked for, earlier at CTV and now at Global National, can pull in 1 million on a real good day, but are usually hovering between 700,000 and 900,000 viewers per show. A top-rated show television show in Canada — American Idol, let's say — will do better than 2 million viewers. The Toronto Star, the country's biggest daily newspaper, is selling about 350,000 copies a day. That would be your mass media benchmark.
