I don’t watch any show regularly except for reruns of Scrubs, as my attempt to wean myself of the cursed box seems to be working. So instead I’ll list my favorite 6 shows of this century.
In no order:
The aforemetioned Scrubs
**Gilmore Girls ** (before the current season)
*Firefly * (taken too soon from us, alas!)
Angel
Buffy the Vampire Slayer (though it is amazing how there were virtually no black, Asian, or Hispanic persons in that part of Caliafornia)
Law & Order: CI (Eames/Goren version only, and certainly prior to the current squad commander)
Star Trek: Deep Space Nine (which doesn’t qualify under my own rules, but I couldn’t think of a more recent program I liked more)
Gilmore Girls
House
Medium
Supernatural
Simpsons
Futurama
In no order (assuming this is “currently in production or on hiatus” AND “that you watch currently” [no "used to watch it]):
**My Name Is Earl
Rome (though I don’t have HBO)
The Daily Show
The Colbert Report
American Idol
Project Runway** (still wish Jeffrey hadn’t won- I know he’s talented, but he needs to be seriously battered [preferably by middle-aged overweight women with bats and chains] before he can get an award)
Shows that are still on and/or still in production:
The Office
24
Scrubs
The Shield
The Colbert Report
South Park
But the following canceled or finished shows could bump them:
Buffy the Vampire Slayer
Angel
Arrested Development
In rough order
The Colbert Report
Futurama
The Daily Show
The Simpsons
Family Guy
Scrubs
The Daily Show
Scrubs

I don’t think there’s a Canadian version is there? I’d love it if there were, but I think the original version was British, and then there was the US remake, by the Showtime network.
Currently being aired shows:
24
Rome (but series finale is Sunday so I am going to list seven shows - sue me)
Ugly Betty
Boston Legal
Shield
Wire
Sopranos
Honorable mention:
Dirt
Prison Break
Lost
Heroes
Two And A Half Men
Andy Barker PI (new show starring Andy Richter that is actually very funny)
American Idol (only to hear Melinda and Lakisha sing)
Anthony Bourdain: No Reservations
House Hunters
The Riches
Shark
And there you have pretty much my entire DVR listings.
I know that theoretically it was American, but it was filmed in Toronto, produced by Temple Street Productions along with Showtime, and its various directors were Canadian. And even though most of the lead actors were American, at least one - Thea Gill (Lindsay) - was Canadian, and all the secondary characters were Canadian…
Liberty Avenue my butt - it was filmed about two blocks from my house… 
Daily/Colbert
CSI
South Park
Rome

I have HBO, but haven’t seen The Wire because I didn’t start watching it from the beginning. I’ll rent the DVDs and try to get caught up, and maybe that will displace something else on my list.
Regrettably, many of my favorite shows aren’t on anymore…
- Mystery Science Theater 3000 - kinda surprised no one’s mentioned this yet, but then again, it’s sort of a cult thing, so I dunno. Still, it’s a show reliant on good comic timing and subtlety, which I think is painfully missing from some shows today (SNL, I’m looking at you…).
- Taxi - IMO one of the best sitcoms past or present. Louie De Palma is one of my all-time favorite TV characters.
- Da Ali G Show - short run but extremely hilarious, although it helps to have been into this one before all the Borat over-hype this past year.
- Mythbusters - it’s like that end-of-year violent chemistry experiment that the whole class waited for, except it happens every episode! Interesting, funny, and informative.
- Spongebob Squarepants - my favorite recent cartoon, it had some great subversive humor in the first three seasons. Sadly, the show seems to have taken a turn downhill since then (plus the same overhype problem that Borat had).
- The Daily Show/Colbert Report - when the real news gets too depressing, I turn to the bastions of fake news to give me a little something to laugh about.
I’m just doing ones that are on right now, though I feel compelled to mention that Seinfeld, Monty Python’s Flying Circus, and the old Doctor Whos (esp Pertwee, T. Baker, and Davison), and Buffy the Vampire Slayer are my all-time favorites.
Anyway, more or less in order:
Mythbusters
The Daily Show
Eureka
Dirty Jobs
The Colbert Report
Antiques Roadshow
The new Doctor Whos might have made it if they weren’t so preachy, and if it weren’t for all the “You human beings are just so wunnerful I wanna take you home and just kiss you all over,” and the, “Oh, you British are just the bestest of all the already wunnerful human beings” crap, but all that seems to take up about half of each script.
