She Left Law School for the Studio. Now Kayla Diamond Is One of the Most Credible Voices in Canadian Music.

There's a particular kind of confidence that only comes from betting on yourself and winning. Kayla Diamond has that energy. She walked away from law school in 2016 after landing her first record deal, and within a year her debut single "Carnival Hearts" had cracked the Canadian Billboard radio charts Top 30 and earned her a Canadian Radio Music Award nomination alongside Jessie Reyez. That's not a soft entry into the industry. That's a statement.

But what makes Diamond's story genuinely compelling isn't the debut chart run. It's what she did next. Most artists who land a charting single double down on performance, touring, features, the whole artist-facing machinery. Diamond quietly pivoted inward, toward the craft, toward the people and songs behind the curtain. She started producing. She started writing for other artists. She started building something bigger than her own name.

That instinct proved sharper than most people realize at the time.

"It was a really interesting experience for me to be an artist first, because you don't see a lot of labels where the president knows what it's like to be in the artist's shoes, the songwriter's shoes, and the producer's shoes. Having that experience seems like the pre-requisite for exactly what I'm doing now."

By 2024, she'd formalized that vision into Kolossal Records, a joint venture with The Orchard, making her one of the youngest female label owners in Canada. That's not a vanity project or a vanity title. That's infrastructure, built by someone who understands the full chain of how music actually moves.

The catalogue she's assembled since stepping behind the boards is hard to argue with. Over 85 million cross-platform streams, steady radio play, and recognition from names like Tiesto, Armin van Buuren, and Hardwell. Syncs on NBC's The Voice, Netflix's My Little Pony, The Ultimatum, and The Kardashians. A number one record on the CBC Top 20 and a SOCAN Rock Award for the Strumbellas' "Hold Me", a song that spent 30 straight weeks on cross-platform rotation. A 2025 Juno nomination for Rap Album of the Year for her contribution to Dom Vallie's "See You When I See You". A Silver Clio Award for her work with Banners on the Kids Help Phone campaign. And heading into 2026, she wrote, produced, and sang the title sequence for Rebel Wilson's summer comedy "Bride Hard", currently in theatres worldwide.

"The first challenge was to re-introduce myself to the industry that only knew me as 'Kayla Diamond, singer of Carnival Hearts.' What I've learned is that this is a wildly male-dominated industry that needs more women in positions of power who stand up for their vision."

That candor matters. Diamond isn't interested in performing the role of the approachable creative for optics. She's built a reputation in sessions for exactly the kind of directness and structural thinking that's hard to fake, and she's known for her ability to understand pop structure and fortify hooks, the kind of skill that gets you called back into rooms with artists across genres.

When she joined Dom Vallie's sessions, for instance, it wasn't her natural lane. "I've always been focused on pop music, so when I got the call to come in and collaborate with Dom and the duo Just Ideas, I was a little nervous to enter a world that they had already well-established," she's said. "My strength within songwriting is structure and pop hooks, but I never want to come in and change something that's already working for an artist or mess with the flow. For me it was about finding a way to enhance what was already there." The result helped push that project to a Juno nomination. That's the difference between a songwriter who writes songs and one who reads rooms.

On June 18th, Kayla Diamond is stepping into Beatcave's Cave Club session, and it's exactly the kind of conversation our members need to be part of. This isn't a panel, it's not a workshop with handouts, and it's not a networking mixer where you exchange Instagram handles with strangers. It's a direct exchange with someone who has navigated every corner of the music industry, from performing on charts to writing chart records for others, from landing syncs to running a label, from building hooks in sessions to building infrastructure through a major distribution deal.

If you're an artist trying to figure out where your music is headed, this is the room. Diamond's perspective on songwriting, production, artist development, and the realities of the Canadian music landscape is hard-earned and specific. She's not going to tell you what you want to hear. She's going to tell you what's actually useful.

"I've learned to believe my gut a lot more and not bury my voice."

That's the kind of clarity that only comes from having tested yourself, lost some ground, regained it differently, and built something real on the other side of it.

Cave Club on June 18th is a members-only session. Space is limited. If you want honest feedback on your music, an inside look at how one of Canada's sharpest behind-the-scenes operators thinks about sound and creative direction right now, don't sit this one out.
