McGrath started his career as a TV producer at the educational network TVOntario. In 1993, he was hired by Moses Znaimer and went to work at Toronto's groundbreaking Citytv station. As a producer on the Gemini Award-winning MediaTelevision, McGrath made the program on the intersection of digital culture and marketing one of the first in Canada to maintain an email address. Between 1993 and 1997, he did over five hundred stories on the first wave of dot.com entrepreneurs, interviewing new media figures such as John Perry Barlow, Bruce Sterling, Peter Gabriel, and Nicholas Negroponte, as well as authors and TV types from P. J. O'Rourke to Chris Carter.
In 1997, McGrath signed on as the first producer for Space: The Imagination Station, Canada's Sci-Fi channel. There, he pioneered several of the station's early program segments, including a recurring comedy segment called "Conspiracy Guy". He also created and hosted the show's late-night movie show, Spacebar.
In late 2000, McGrath left Space: The Imagination Station to become a resident of the Canadian Film Centre's Prime Time TV program.
On August 26, 2008, Across the River to Motor City received seven Gemini Award nominations. McGrath was nominated for Best Dramatic Writing in a Miniseries, along with Bob Wertheimer and Jocelyn Cornforth.[3]
In 2002, on a lark, McGrath wrote the book and lyrics for a satirical musical based on the movie Top Gun: Top Gun! The Musical, which became the highest grossing show in the history of the Toronto Fringe Festival. It was remounted in a successful commercial production at the Factory Theatre in June 2003, and was nominated for two Dora Mavor Moore Award for Best Musical and Best Leading Performance Male, Dmitry Chepovetsky.[4]
Top Gun! The Musical has received several productions, in Texas and Halifax, N.S. In 2004, the original cast and creative team, led by Director Colin Viebrock, producer Derrick Chua, and writers McGrath and Scott White took the show to the inaugural New York Musical Festival. McGrath wrote several other plays, including Press'd, American Without Tears and Pavlov's Brother (co-written with Flashpoint co-creator Mark Ellis).[citation needed]
Blog
In August 2005, McGrath started a blog called "Dead Things on Sticks." Initially a personal screenwriting blog, the site soon morphed into a much-read daily discussion covering the Canadian television industry.
