Early life and migration
Before Oyin Oladejo became a familiar presence to Star Trek: Discovery viewers as Lieutenant Joann Owosekun, she was a newly arrived teenager figuring out how to make a life—and eventually a creative home—in Toronto. Nigerian-born and raised, Oladejo’s migration to Canada set the coordinates for a path that would run through rigorous theatre training, seasons of stage work, and then a leap to a global franchise. That arc matters, because it explains the steadiness and specificity audiences recognize in her: a performer whose on-camera restraint is built on years of speaking text, listening deeply, and understanding ensemble craft.
She has spoken about how the move sharpened her sense of purpose, and how the multicultural fabric of Toronto gave her the room to pursue performance seriously. The result is a career that carries the imprint of multiple traditions—West African family storytelling, Canadian theatre practice, and genre screen work—and a performer who navigates all three with ease.
Training & mentors
Oladejo’s training years are less publicized than her bridge-console close-ups, but they’re the foundation of her screen presence. Toronto’s conservatory-style actor training emphasizes voice, text, and movement, and her path followed that discipline: Shakespeare and classical text work to build musculature; voice and speech for clarity and presence; and movement practices that translate into grounded stillness on camera.
Those years also brought mentors—directors, vocal coaches, and seasoned actors—who modeled rigor and flexibility. It’s not flashy material for a headline, but it shaped the way she approaches roles: attentive to language, precise about objectives, and comfortable inside an ensemble. The habits you learn in rehearsal rooms—how to lift text without pushing, how to make space for scene partners, how to modulate energy for a 500-seat house—have direct equivalents on a series that shoots fast, carries dense world-building, and relies on a company to carry story week to week.
Toronto stage years
Before Discovery, Oladejo built a résumé in Toronto’s theatre ecosystem—readings, workshops, indie houses, and classical stages—where actors are routinely asked to shift between canon and new Canadian writing. Those seasons are the under-told part of her story, but they’re key to why she reads as dependable and detailed on screen. Working in repertory, stepping into a lead in a new-play workshop on short notice, or retooling a role between previews—all of that builds a muscle for adaptation.
You can see the theatre scaffolding in the way she handles exposition-heavy dialogue, and in the economy of gesture that screen directors prize. And for a performer migrating between cultures and mediums, Toronto’s collaborative rooms become a refuge: places where a multiplicity of accents, histories, and sensibilities are assets, not obstacles.

Discovery turning point
Star Trek: Discovery was the acceleration point. As Owosekun, Oladejo stepped into a 23rd-century bridge where every reaction shot matters, and every eye-line tells story. In Paramount+’s cast materials, she introduced herself simply: “I play Lieutenant Joann Owosekun,” an operations officer whose steadiness under pressure became a visual anchor for the ship’s found family. The job required exactly what stage seasons teach: focus, generosity, and the ability to deliver truth in a tight frame.
Her contributions were notably felt in arcs that tracked the bridge crew’s cohesion and mutual care. Speaking with Space.com about the show’s ensemble, she underscored the off-screen bond that feeds on-screen chemistry: “We really support each other,” she said, describing the collaborative environment that let quieter character beats land without speechifying. Discovery gave her a global platform; it also clarified for many viewers that the so-called “supporting” craft of listening and responding is a star-making skill.
Beyond Trek: Endlings and Orah
Away from the transporter pad, Oladejo continued to diversify her screen work. In the sci‑fi/adventure series Endlings, she stepped into a family-forward genre framework made in Canada, showcasing a different register—grounded, contemporary, and keyed to younger audiences. The show’s blend of creature feature and social themes gave her room to thread empathy through action.
Then came Orah, a Nigerian‑Canadian feature that landed as a defining turn. In Lonzo Nzekwe’s thriller, Oladejo plays a Toronto taxi driver and mother pulled into the cross‑border machinery of power and survival. It’s a lead performance that draws deeply on her stage training: unshowy, precise, and powered by a clear spine of intention. The industry took note. Her Canadian Screen Award nomination for Performance in a Leading Role (Orah) marked a public acknowledgment that the actor many viewers knew from a bridge console could carry a feature with authority.
The nomination matters for another reason: it situates Oladejo within a wave of diasporic storytellers making work that moves fluidly between Canada and Africa, and between genre and social realism. Orah’s Toronto streets and Nigerian ties aren’t just setting—they’re part of a larger ecosystem that Oladejo navigates with lived knowledge.
Craft & ethos
Ask actors who spend serious time on stage what carries them on camera, and the answers are consistent: breath, listening, and specificity. Oladejo’s screen work is a case study. The breath control that powers Shakespeare lines becomes the ability to sit in silence without the frame going dead. Listening, a theatre essential, reads in close-up as presence. Specificity—of objective, of physical life—means she never needs to telegraph.
There’s also an ethos that comes through in interviews: discipline without austerity, curiosity without self-indulgence. In official Star Trek press, she often returned to ideas of representation and responsibility. Paramount+ Q&As have her stressing the impact of seeing yourself in the future: “It means a lot to be part of a world that reflects the world we live in,” she noted, connecting Discovery’s inclusive casting to the lived experience of fans. That framing helps explain why Orah resonates, too—a story anchored in a Black immigrant woman’s agency and love, played by an actor whose craft resists caricature.
Theatre artists also talk about community as a professional value. That’s visible in the way colleagues describe Discovery’s bridge ensemble and in how Oladejo frames collaboration: the work is shared, and the wins are collective. As she told Space.com about the cast’s bond, “We really support each other,” a simple line that aligns with how she moves through projects—eyes on partners, story first.
What’s next
With Star Trek: Discovery’s final season completed and Orah cementing her feature lead bona fides, the next phase is already visible in concrete ways. Orah has been on the awards circuit and release path typical for Canadian independent features, which keeps Oladejo in front of festival programmers, press, and casting directors across markets. Endlings remains available to stream, and Discovery is archived on Paramount+, introducing her to new viewers globally who are arriving late to the series.
Industry-facing profiles and credits databases show an actor positioned to continue toggling between screen and stage, and between Canadian and international projects. The practical consequence of Discovery’s wrap is calendar flexibility; the professional consequence of a CSA nomination is a widened lane. Both are facts, and together they suggest a year ahead in which Oladejo’s range—intimate drama, ensemble genre, theatre-honed text—can be put to work where it’s most valued.
Oyin Oladejo’s path makes a coherent story when you look beyond the bridge: migration that sharpened purpose; training that built durable technique; Toronto stages that taught her how to carry story alongside others; a Star Trek turn that opened doors without defining her limits; and a lead performance in Orah that signals staying power. For fans who met her on Discovery and sensed there was more craft beneath the calm, there’s satisfaction in seeing the arc confirmed. The picture that emerges is not just of an actor on the rise, but of a maker whose choices—mentored, deliberate, and community-rooted—keep expanding what a Nigerian‑Canadian career in genre and drama can look like.
