## Early acting career
Seater began acting as a child. [TV Guide](https://www.edgepedia.org/tv-guide) and Rotten Tomatoes both state that his acting career began when he was ten years old, with early appearances in the drama *Twice in a Lifetime* and the television films *Vanished Without a Trace* (NBC) and *Dirty Pictures* (Showtime).[1](https://www.tvguide.com/celebrities/michael-seater/bio/3000386881/) • [4](https://www.rottentomatoes.com/celebrity/michael_seater) Through the early 2000s he worked steadily in Canadian children's and family television, starring as Lucas Randall in *Strange Days at Blake Holsey High* (2002–2006) and voicing Mattimeo in the animated *Redwall*.[3](https://www.tvmaze.com/people/92311/michael-seater) • [5](https://www.valeorine.com/reference/michael-seater)
His awards record from this period reflects that workload: Gemini nominations in 2006 and 2007, a 2009 Gemini win for Best Performance in a Children's or Youth Program or Series, and nominations and a win at the Young Artist Awards.[1](https://www.tvguide.com/celebrities/michael-seater/bio/3000386881/) • [2](https://www.them.us/contributor/michael-seater)
## Life with Derek and leading television roles
**Derek Venturi.** From 2005 to 2009 Seater played the title role of Derek Venturi on *Life with Derek*, the Family Channel comedy about two blended families in [London, Ontario](https://www.edgepedia.org/london-ontario); he appeared in 70 episodes and also wrote two episodes of the series.[3](https://www.tvmaze.com/people/92311/michael-seater) • [5](https://www.valeorine.com/reference/michael-seater) He returned to the character in the television film *Vacation with Derek* (2010) and again in the reunion film *Life with Luca* (2023).[4](https://www.rottentomatoes.com/celebrity/michael_seater)
Between and after these films he held or shared leading roles in several Canadian series: Tom Bellow in CBC's *18 to Life* (25 episodes, 2010–2011), Ivan Buchinsky in *Bomb Girls* (2012–2013), and James Clarkson in *The Wedding Planners*, a role he has played since March 2020.[3](https://www.tvmaze.com/people/92311/michael-seater) • [1](https://www.tvguide.com/celebrities/michael-seater/bio/3000386881/)
## Murdoch Mysteries and James Gillies
Seater's most durable character role is James Gillies, the murderer and criminal mastermind he played on the period detective drama *Murdoch Mysteries* from 2009 to 2017.[1](https://www.tvguide.com/celebrities/michael-seater/bio/3000386881/) TVmaze lists nine episodes on *Murdoch Mysteries* plus a further seven on its spin-off *Macy Murdoch*, with additional episodes dated 2023 and 2026, so the role has extended well past the run usually cited for the character.[3](https://www.tvmaze.com/people/92311/michael-seater) In a 2020 interview, Seater described playing the villain as a chance to "come in guns blazing," with needles to babies' necks and hairpins to women's throats, and get his face mangled.[8](https://www.tv-eh.com/2020/04/01/the-wedding-planners-michael-seater-it-speaks-to-themes-i-think-everybody-can-get/)
## Move behind the camera
Seater describes film sets as his film school: an actor from childhood, he would watch dailies as a teenager and analyze how the previous day's shooting had translated on screen.[6](https://www.michaelseater.com/about)
**Short film.** His short film *SLY CAD* (2014), which he wrote, directed, and starred in, was selected for Telefilm Canada's Not Short on Talent program at the Cannes International Film Festival.[2](https://www.them.us/contributor/michael-seater) • [6](https://www.michaelseater.com/about)
**Feature films.** His first feature, *People Hold On* (2015), written and directed with a story credit on *The Definites* and *Sadie's Last Days on Earth* to follow, opened in theaters across Canada and was nominated for a Canadian Screen Award, in the Best Original Song category for [Noah Reid](https://www.edgepedia.org/noah-reid)'s contribution.[2](https://www.them.us/contributor/michael-seater) • [5](https://www.valeorine.com/reference/michael-seater) His second feature, *Sadie's Last Days on Earth* (2016), a comedy about a high school student preparing a checklist for predicted doomsday, won a Leo award and was picked up by Netflix.[7](https://www.michaelseater.com/work) • [6](https://www.michaelseater.com/about) As an actor he also appeared in *Adventures in the Sin Bin* (2012), *Bank$tas* (2014) with [Alan Thicke](https://www.edgepedia.org/alan-thicke), and *The Definites* (2017), which he also produced.[4](https://www.rottentomatoes.com/celebrity/michael_seater)
## Branded content and commercials
A substantial part of Seater's directing work sits where narrative storytelling meets brands. He directed Walmart's first ever narrative series, the 20-episode comedy *Upstairs Amy*, and *Emerald Code*, a 30-episode STEM adventure series made with Ubisoft and Canada 2067.[7](https://www.michaelseater.com/work) • [2](https://www.them.us/contributor/michael-seater)
His commercial portfolio centers on fashion and beauty clients. For Holt Renfrew he directed multiple campaigns, including a Spring 2021 brand film in which *Gossip Girl* star Jordan Alexander covers "Lovers in a Dangerous Time," a Pride 2023 video, and a [Lunar New Year](https://www.edgepedia.org/lunar-new-year) video marking the retailer's expansion into the kids market, which won a Silver medal at the Media Innovation Awards for Best in Branded Content.[7](https://www.michaelseater.com/work) Other credits include a launch campaign for the W Hotel Toronto, a fashion film commissioned by [Thom Browne](https://www.edgepedia.org/thom-browne) featuring the musician [King Princess](https://www.edgepedia.org/king-princess) for *The Cut*, the DSQUARED2 film *Brokeback Beach* shot in Mykonos with actor Zane Phillips, and music videos including Noah Reid's "Honesty" and King Princess's "Hit the Back."[7](https://www.michaelseater.com/work) • [6](https://www.michaelseater.com/about)
## Identity and advocacy
Seater identifies as queer and has described drawing on his own perspective to make queer characters feel honest rather than put-on, an approach he applied in developing his character James on *The Wedding Planners*.[8](https://www.tv-eh.com/2020/04/01/the-wedding-planners-michael-seater-it-speaks-to-themes-i-think-everybody-can-get/) In 2023 he joined Covenant House Toronto's Next Generation council and raised money through his first Sleep Out, an annual fundraiser in which participants sleep on the street for a night to support the agency's work with youth experiencing homelessness and trafficking; he cited the organization's figure that 30 percent of homeless youth identify as 2SLGBTQIA+ and that family rejection is the most common cause of homelessness in that population.[9](https://covenanthousetoronto.ca/2023/04/13/sleeper-spotlight-actor-director-producer-michael-seater/)
