Definitely Quantico and Designated Survivor. Both are incredible. White Collar is still my favorite show of all time.

See if Leverage suits you.

try Burn Notice. and Chuck. i loved both of those, and it may be the exact thing for you.
they are witty, funny, serious, explosions
and Bruce Campbell (in Burn Notice) and Adam Baldwin (in Chuck, no relation to Alec)
these i think are the closest thing to White Collar for what you want.

Previous posters have mentioned stuff like Castle Prison break etc. Strongly recommend you watch The Mentalist. Patrick Jane has a few glimpses of Caffrey and I think you might enjoy it

So others have mentioned Person of Interest and Burn Notice, I'd add Psych, Justified, and Mad Men to the list of shows you should check out.

you may like Burn Notice, that is my all time favorite show, i watched Whited Collar after BN.
i loved both shows, and found a lot of similarities between them, drama and comedy.
you may like it.

I recently watched Psycha bs really enjoyed it. Was more comedic and lighther than Whie Collar, but the I highly recommend if you liked WC. Along with others, I also recommend Chuch. I stuck through where others may have lost interest but overall a great series

ooh I like the name "Da Vinci's Demons". I'll check it out.
"Whatever I did, I have proof I didn't do it" Neal Caffrey

Da Vinci's Demons is great, though it's a shame there probably won't be a season 4.

Bosch, Banshee, Billions, The Expanse, Justified.

Psych is great! Watched that whole series through recently before starting White Collar

I recommend Psych, Monk, and Castle. They all have lovable main casts and stories that have a good mix of comedy and drama.

Lol great minds do think alike
And yeah I watched the whole show a while ago over the course of like a week or two so it's kind of a blur but I remember it being good, although I'm pretty sure I didn't love the ending, it wasn't a bad ending (no spoilers) I personally just wasn't a fan.
I heard it's not on Netflix anymore though so that sucks, but maybe it's just not on Canadian Netflix anymore.

Great minds think alike
Btw did you watch the entire series, Chuck? I kinda lost interest somewhere along the way. After Chuck & Sarah got married I think. I do want to go back and finish tho.
"Whatever I did, I have proof I didn't do it" Neal Caffrey

Haha yeah, actually I watched White Collar after seeing Matt Bomer on Chuck

I started watching Chuck for Matt (Bryce Larkin) as I was really missing seeing him after WC ended.
It's a great series, Zac Levi, Yvonne Strahowski are great in it. It has the general light, fun vibe of WC with good mystery and great moments. The supporting cast is just as good.

I just skim-read this thread but I was a fan of Chuck, and Psych, which are both kind of similar.

It's not a new show, but you might like
Remington Steele
. The premise of the show is that a female private detective named Laura Holt can't get any clients because she's a woman, so she invents a fictitious male boss named Remington Steele. When she catches a charming thief, she winds up having to get him to masquerade as Steele to help her out of a predicament, and the masquerade becomes a permanent arrangement. It's very humorous, but also often suspenseful. In some ways, it was like a prototype for
White Collar
, and Pierce Brosnan's Remington Steele was the Neal Caffrey of his day.

If you didn't care much for Monk you probably won't like psych but I loved that show it used to play around the same time WC aired on USA. You might not like it because it had a lot of "hullabaloo" but it was meant to have it. If you have not you should check it out and see if its something you might like.
"Baby sister, I was born game and I intend to go out that way"

Thanks!!
VM is on my list, I have watched it occasionally when it aired.
Monk - I think I watched most of the first season, then it started to bore me and it was a tad too much hullabaloo-ish, jmo of course! Maybe I'll give it another chance though :).
Quinn: Cause of Death? Masuka: Gravity

If you don't mind "old/finished" TV shows, I could also recommend Veronica Mars.
It's only 3 seasons and a movie(who was shot years later for the fans), but it pretty much has what you ask for. Comedy, Drama and suspense. Both comedy and drama are very balanced, though sometimes it has a darker tone, but there is always something light hearted around the corner. Think of Veronica Mars as "Columbo/Monk" style thing but in modern times with young people xD
Which brings me to Monk. If you like House, you might like Monk as well. It's a "COTW" type crime show, but with a lot of the characteristics of House, meaning one "socially awkward" guy is the lead and he has very few people around him that get along with his quirks and behaviour, but he is one of the best in his field.

Thanks - I'll check that out!
Quinn: Cause of Death? Masuka: Gravity

I recently finished watching Forever and it was good.
Lucifer is another one that seems interesting (premise-wise, same as Castle or Forever)
