If you grew up in the early 2000s, you probably spent at least one afternoon screaming "I'm Just a Kid" into a hairbrush. It’s a rite of passage. But while some bands from that era disappeared into the "Where are they now?" void of VH1 documentaries, these guys stayed. They stayed together. That’s actually the weirdest part about the band members of Simple Plan—they’ve had almost the exact same lineup since 1999. In an industry where people quit over "creative differences" (usually code for someone stole someone else's girlfriend or royalty check), Simple Plan is a weird anomaly of stability.
Most bands are a revolving door. Not this one.
The Core Four (and the one who stepped away)
Pierre Bouvier is the face. You know the voice—nasal in that perfect, California-via-Montreal way that defined the Warped Tour era. Pierre didn't start as the singer, though. Back in the day, in a band called Reset, he played bass and sang. It wasn't until Simple Plan started taking shape that he ditched the instrument to focus on being a frontman. Honestly, it was a smart move. He’s got that tireless energy that makes 40-year-olds feel like they're still 15 and angry at their parents.
Then you have Chuck Comeau. He’s the drummer, but he’s also basically the CEO of the band. Chuck and Pierre have been friends since they were like 13. They are the songwriting engine. If Pierre is the melody, Chuck is the logic. He’s the one who’s constantly on social media, talking to fans, and making sure the "SP Crew" is fed. He actually went to journalism school for a hot minute before the band blew up. You can tell. He’s meticulous.
The Strings: Jeff and Seb
Jeff Stinco is the lead guitarist. Unlike a lot of pop-punk players who just chug power chords, Jeff actually knows his way around a fretboard in a technical sense. He studied classical guitar. You don’t hear a ton of Mozart in "Addicted," but that technical foundation is why their live shows are so tight. He’s the guy with the shaved head and the permanent "I'm happy to be here" grin.

Sébastien Lefebvre is the rhythm guitarist and the secret weapon on backing vocals. If you listen to their harmonies, that’s usually Seb. He’s also the guy who keeps the band's "vibe" grounded. He’s got a side project or two, but his loyalty to the main ship is pretty legendary. He’s often the one doing the French-language interviews back in Quebec because, yeah, lest we forget, these guys are very, very Canadian.
What happened with David Desrosiers?
We have to talk about David. For twenty years, David Desrosiers was the bassist. He was the high-energy, wild-card member who did the crazy jumps and provided the high-pitched backing vocals that defined the No Pads, No Helmets... Just Balls era.
In 2017, David took a break to deal with major depression. He was open about it, which was actually pretty brave at the time. He came back for a bit, but then in 2020, he left the band permanently following allegations of sexual misconduct that surfaced on social media. The band acted fast. They cut ties, issued a statement, and moved on as a four-piece. Since then, they haven’t officially replaced him. When they play live, they use a touring bassist or Pierre just plays some bass parts in the studio. It’s a heavy chapter in their history, but it's part of the reality of the band members of Simple Plan today. They chose to protect the brand and their fans over keeping the "original five" narrative alive.
Why they haven't broken up yet
It’s the friendship. That sounds like a cliché you'd hear on a Disney Channel press junket, but with these guys, it’s actually true. They grew up in the same suburbs of Montreal. They ate the same poutine. They struggled through the same cold winters trying to get people to listen to their demos.

When they hit it big with "Welcome to My Life," they didn't go the "rockstar" route of destroying hotel rooms and hating each other. They bought houses near each other. They started the Simple Plan Foundation, which has donated over $2 million to youth-related charities. They turned the band into a family business.
Most people don't realize how much work it takes to keep four (formerly five) different personalities aligned for two and a half decades. They’ve navigated the death of pop-punk, the rise of emo, the total collapse of the CD market, and the TikTok revival of their own songs.
The "Reset" Connection
If you want to be a real nerd about it, you have to look at Reset. That was the band Pierre and Chuck were in before Simple Plan. When Chuck left Reset to go to school, Pierre stayed. Then Pierre left, and they eventually recruited Jeff, Seb, and David. It’s like a puzzle where the pieces kept moving until they finally clicked. The chemistry between the band members of Simple Plan isn't accidental; it’s the result of failing in other bands first.
The Simple Plan Sound: Who does what?
- Pierre Bouvier: Lead vocals, occasional guitar, the guy who writes the lyrics that make you feel like he read your teenage diary.
- Chuck Comeau: Drums, lyrics, social media mastermind, the "business" brain.
- Jeff Stinco: Lead guitar, the guy who ensures the solos actually sound like music.
- Sébastien Lefebvre: Rhythm guitar, backing vocals, the "glue" of the group's live sound.
They don't try to be Radiohead. They know what they are. They are a band that writes songs about feeling misunderstood, even though they are now multi-millionaire dads in their 40s. And the fans don't care that they're older. When you see the band members of Simple Plan on stage now, they have the same energy they had at the 2003 MTV Video Music Awards. It’s a bit of a time capsule, but it’s a high-quality one.

The 2026 Perspective: Where are they now?
As of 2026, the band is still touring heavily. They’ve embraced their status as "elder statesmen" of the pop-punk scene. You'll see them headlining nostalgia festivals like When We Were Young, but they’re also putting out new music that somehow still charts. They’ve managed to bypass the "cringe" factor by being incredibly self-aware. They know "I'm Just a Kid" is their legacy, and they play it with zero irony.
The dynamic between the members has shifted from "angry kids" to "professional brothers." They’ve survived the industry's meat grinder by sticking together when everyone else was splitting up to try solo careers that usually went nowhere.
If you're looking to really understand the band, don't just look at their Spotify numbers. Look at their credits. You'll see the same names over and over. Bouvier. Comeau. Stinco. Lefebvre.
How to follow the band today
If you want to keep up with what the guys are doing, social media is actually the best bet. Unlike some legacy acts who hire a 22-year-old intern to run their Instagram, Chuck and Seb are often the ones actually posting.
- Check the Simple Plan Foundation: If you want to see what they care about outside of music, look at their charity work. It’s the best indicator of their actual character.
- Watch the "I'm Just a Kid" TikToks: They leaned hard into the viral trend, and it’s a great way to see how they interact with a new generation of fans.
- Live Shows: They are arguably better live now than they were in 2005. The vocals are more stable, and the production is massive.
Actionable Insight for Fans:
If you're tracking the history of the band members of Simple Plan, start by listening to their 2022 album Harder Than It Looks. It’s the first album they released as a quartet and without a major label. It’s the purest distillation of who they are right now: independent, slightly older, but still incredibly loud. Also, pay attention to the songwriting credits on their early work versus their new stuff; you'll see how the Pierre-Chuck partnership has evolved from teenage angst into a polished songwriting machine that knows exactly how to trigger your nostalgia.
The lineup might be one person short these days, but the DNA of the band hasn't changed. They’re still the same kids from Montreal, just with better equipment and significantly less hair gel.
