Who Is Patrick McKenna on The Red Green Show?

Patrick McKenna is the Canadian actor who played Harold Green, the nerdy nephew of Red Green, on The Red Green Show. If you're trying to connect the actor to the character, the short answer is: McKenna is Harold — the clipboard-carrying, safety-obsessed foil to Red's duct-tape philosophy at Possum Lodge. The Classic Red Green Show Page lists both "Patrick McKenna" and "Harold Green" among its core keywords and maintains dedicated sections for Characters and Mythical Characters, making it a useful fan-built reference for cast and character details.

The actor behind Harold Green

McKenna's role as Harold is the main reason his name comes up in Red Green conversations. Harold is Red's nephew, and the show uses that family tie to set up one of its central comic dynamics: Harold represents book-smart caution, while Red represents improvised, hands-on (and frequently unsafe) solutions.

That contrast is the engine of many scenes. Harold typically arrives with a plan, a regulation, or a warning; Red typically ignores it and reaches for the duct tape.

Harold's personality and his place at Possum Lodge

Harold functions as the show's resident worrier and would-be professional. His traits tend to cluster around:

• Rule-following and safety concerns — he is the character most likely to cite procedures or object to a dangerous idea.
• Eagerness to be taken seriously — he wants credit for his competence, which the other lodge members rarely give him.
• Awkwardness — his attempts to be authoritative usually undercut themselves.

Against the lodge's older, more easygoing members, Harold reads as the odd one out. That is the point: he is the younger, more anxious generation bouncing off Red's unbothered veteran.

McKenna beyond The Red Green Show

McKenna is a working Canadian actor, and Harold is one prominent role among many rather than his only credit. If you want a fuller filmography, an industry database or his own professional listings will serve you better than a fan site — the Classic Red Green Show Page is built around the show itself, not around cast biographies.

Why Harold left, and how the show handled it

Harold's departure is a common point of confusion for viewers who notice the character's absence in later seasons. The show wrote Harold out and continued without him, and later episodes reference him rather than featuring him as a regular presence.

Because details of the exit and the exact nature of those later references vary by season and by how the show was packaged in different markets, treat any specific account with care. The most reliable approach is to check episode-by-episode rather than rely on a single summary.

Where to verify cast and character details

The Classic Red Green Show Page is a fan-driven site focused on the early years of the show, and it explicitly frames itself as a place for "nothing but the facts about this iconic Canadian show." Relevant sections include:

Two caveats worth knowing before you rely on it:

1. It is a fan site, not an official production source. The site describes itself as "the largest fan driven website for the Red Green Show" and asks readers to email corrections or submit new information and pictures.
2. It is actively being updated. As of the site's 25th-anniversary notice, the maintainer states that roughly 10–12 months of collected tips and research are still being added to the relevant areas, so some sections may be incomplete or in flux.

If you need authoritative cast credits, cross-check against official production materials or a professional credits database. Use the fan page for context, character background, and the kind of detail that official sources rarely bother to record.
