For many people around the world, John Dunsworth will always be remembered as the unforgettable Jim Lahey from Trailer Park Boys. His performance as Sunnyvale’s perpetually intoxicated trailer park supervisor became one of Canada’s most celebrated comedy roles and introduced a Nova Scotian actor to an international audience. But long before Lahey became a household name, Dunsworth had already spent decades building an extraordinary career on stages, in television studios and in countless commercials produced throughout Atlantic Canada. He even did some voiceover work.
Long Before Lahey
Born in Bridgewater, Nova Scotia, in 1946, Dunsworth’s path into acting did not begin in front of a camera. He became deeply involved in Halifax’s theatre community during the 1970s, John was a common face at Neptune Theatre as one of the country’s leading regional playhouses. As both an actor and director, he developed a commanding stage presence that made him equally comfortable performing Shakespeare, contemporary drama and comedy. Theatre remained a constant throughout his life, even after television made him famous.
One of the things I appreciate about John and something that’s often true among many theatrically trained actors, is his ability to do anything. Whatever a role required of him, he’d take to like a fish to water. That’s skill.
By the late 1970s and during 1980s, Dunsworth had also become one of the most familiar faces on Atlantic Canadian television beginning with Halifax Cablevision. And anyone who grew up in Nova Scotia during that era likely saw him in local commercials, public service announcements and promotional campaigns. Whether selling everyday products or appearing in regional advertising, he possessed an approachable, distinctly Maritime quality that made him instantly believable, if not comedically so. These performances rarely received much attention, but they made Dunsworth a recognizable figure in living rooms across the province years before his biggest role arrived. Here are a few examples of his advertisements but there are many more over on my Youtube channel.

Enter Sunnyvale
That breakthrough came in 2001 with Trailer Park Boys. As Jim Lahey, Dunsworth created a character whose elaborate speeches, theatrical delivery and chaotic rivalry with Ricky and just about everybody else became central to the series’ success. Remarkably, Dunsworth himself rarely drank alcohol, making his convincing portrayal of perpetual intoxication a testament to his skill as an actor rather than method performance. The series grew from a cult Canadian comedy into an international phenomenon, spawning films, live tours and a devoted global fan base.
Curious Minds: The Lost Series
Yet one of Dunsworth’s most fascinating performances, in my opinion, is also one of his least seen. Why? Because it basically didn’t exist… or almost didn’t.
In 1986, he starred in The Lamplighter, the pilot episode of a proposed CBC educational series called Curious Minds.
Directed by Bill MacGillivray and produced by Ralph Holt, the pilot was filmed in December 1985 at Sherbrooke Village, Nova Scotia.
The series was designed to celebrate Nova Scotian innovation by dramatizing the lives of inventors whose discoveries changed the world. Other planned episodes included the invention of the fog horn and the story of Amherst born physicist Willard Sterling Boyle, whose co-invention of the CCD image sensor laid the foundation for modern digital photography. Unfortunately, CBC never commissioned the series, and development came to an end after the pilot.
The Lamplighter
In The Lamplighter, Dunsworth portrayed Abraham Gesner, the Nova Scotian physician, geologist and inventor whose work transformed artificial lighting. The drama follows Gesner’s experiments with distillation as he searched for a cleaner, more affordable alternative to expensive whale oil for lamp fuel. His breakthrough came when he successfully separated crude coal tar into different fractions, producing a clear, highly combustible fuel that would become known as kerosene. Gesner patented the process in 1854 and initially marketed it as coal oil before kerosene became the common name. The invention dramatically reduced the cost of lighting and helped illuminate homes and businesses around the world.
A Series That Almost Was
What makes Curious Minds especially compelling today is its uniquely Nova Scotian perspective. Rather than focusing on famous international inventors, it celebrated discoveries that originated in this province and demonstrated how local innovation had global impact. It was educational without feeling dry, blending historical drama with scientific storytelling in a way that anticipated later documentary series. Had it been picked up, it might have become one of CBC Halifax’s most distinctive educational programs of the era and probably found use within the education system. Many of the proposed stories have never been put to video.
Today, The Lamplighter survives as a remarkable piece of lost Halifax television history that never was. It captures John Dunsworth years before Trailer Park Boys, showcasing the dramatic ability that often sat beneath his celebrated comedic work. It also preserves an ambitious local production that deserved a much longer life, reminding us that some of Atlantic Canada’s most interesting television stories are the ones that almost happened.
